MAX 7000A Programmable Logic Device Family Data Sheet
MAX 7000A devices use CMOS EEPROM cells to implement logic functions. The user-configurable MAX 7000A architecture accommodates a variety of independent combinatorial and sequential logic functions. The devices can be reprogrammed for quick and efficient iterations during design development and debug cycles, and can be programmed and erased up to 100 times.
MAX 7000A devices contain from 32 to 512 macrocells that are combined into groups of 16 macrocells, called logic array blocks (LABs). Each macrocell has a programmable­register with independently programmable clock, clock enable, clear, and preset functions. To build complex logic functions, each macrocell can be supplemented with both shareable expander product terms and high­speed parallel expander product terms, providing up to 32 product terms per macrocell.
MAX 7000A devices provide programmable speed/power optimization. Speed-critical portions of a design can run at high speed/full power, while the remaining portions run at reduced speed/low power. This speed/power optimization feature enables the designer to configure one or more macrocells to operate at 50% or lower power while adding only a nominal timing delay. MAX 7000A devices also provide an option that reduces the slew rate of the output buffers, minimizing noise transients when non-speed-critical signals are switching. The output drivers of all MAX 7000A devices can be set for 2.5 V or 3.3 V, and all input pins are
2.5-V, 3.3-V, and 5.0-V tolerant, allowing MAX 7000A devices to be used in mixed-voltage systems.

MAX 7000A devices are supported by Altera development systems, which are integrated packages that offer schematic, text—including VHDL, Verilog HDL, and the Altera Hardware Description Language (AHDL)—and waveform design entry, compilation and logic synthesis, simulation and timing analysis, and device programming. The software provides EDIF 2 0 0 and 3 0 0, LPM, VHDL, Verilog HDL, and other interfaces for additional design entry and simulation support from other industry-standard PC- and UNIX-workstation-based EDA tools. The software runs on Windows-based PCs, as well as Sun SPARCstation, HP 9000 Series 700/800, and IBM RISC System/6000 workstations.

Logic Array Blocks

The MAX 7000A device architecture is based on the linking of high-performance LABs. LABs consist of 16-macrocell arrays, as shown in
Figure 1. Multiple LABs are linked together via the PIA, a global bus that
is fed by all dedicated input pins, I/O pins, and macrocells.
Each LAB is fed by the following signals:

Macrocells

MAX 7000A macrocells can be individually configured for either sequential or combinatorial logic operation. The macrocells consist of three functional blocks: the logic array, the product-term select matrix, and the programmable register. Figure 2 shows a MAX 7000A macrocell.

Product Terms
Shared Logic Expanders
Altera Corporation 7
MAX 7000A Programmable Logic Device Family Data Sheet
Combinatorial logic is implemented in the logic array, which provides five product terms per macrocell. The product-term select matrix allocates these product terms for use as either primary logic inputs (to the OR and XOR gates) to implement combinatorial functions, or as secondary inputs to the macrocell’s register preset, clock, and clock enable control functions.
Two kinds of expander product terms (“expanders”) are available to supplement macrocell logic resources:
Shareable expanders, which are inverted product terms that are fed
back into the logic array
Parallel expanders, which are product terms borrowed from adjacent
macrocells
The Altera development system automatically optimizes product-term allocation according to the logic requirements of the design.
For registered functions, each macrocell flipflop can be individually programmed to implement D, T, JK, or SR operation with programmable clock control. The flipflop can be bypassed for combinatorial operation. During design entry, the designer specifies the desired flipflop type; the MAX+PLUS II software then selects the most efficient flipflop operation for each registered function to optimize resource utilization.
Each programmable register can be clocked in three different modes:
Global clock signal. This mode achieves the fastest clock-to-output
performance.
Global clock signal enabled by an active-high clock enable. A clock
enable is generated by a product term. This mode provides an enable on each flipflop while still achieving the fast clock-to-output performance of the global clock.
Array clock implemented with a product term. In this mode, the
flipflop can be clocked by signals from buried macrocells or I/O pins.
Two global clock signals are available in MAX 7000A devices. As shown in Figure 1, these global clock signals can be the true or the complement of either of the global clock pins, GCLK1 or GCLK2.
8 Altera Corporation
MAX 7000A Programmable Logic Device Family Data Sheet
Each register also supports asynchronous preset and clear functions. As shown in Figure 2, the product-term select matrix allocates product terms to control these operations. Although the product-term-driven preset and clear from the register are active high, active-low control can be obtained by inverting the signal within the logic array. In addition, each register clear function can be individually driven by the active-low dedicated global clear pin (GCLRn). Upon power-up, each register in a MAX 7000AE device may be set to either a high or low state. This power-up state is specified at design entry.
All MAX 7000A I/O pins have a fast input path to a macrocell register. This dedicated path allows a signal to bypass the PIA and combinatorial logic and be clocked to an input D flipflop with an extremely fast (as low as 2.5 ns) input setup time.

Expander Product Terms

Although most logic functions can be implemented with the five product terms available in each macrocell, more complex logic functions require additional product terms. Another macrocell can be used to supply the required logic resources. However, the MAX 7000A architecture also offers both shareable and parallel expander product terms that provide additional product terms directly to any macrocell in the same LAB. These expanders help ensure that logic is synthesized with the fewest possible logic resources to obtain the fastest possible speed.

Shareable Expanders

Each LAB has 16 shareable expanders that can be viewed as a pool of uncommitted single product terms (one from each macrocell) with inverted outputs that feed back into the logic array. Each shareable expander can be used and shared by any or all macrocells in the LAB to build complex logic functions. A small delay (t shareable expanders are used. Figure 3 shows how shareable expanders can feed multiple macrocells.

Parallel Expanders

Parallel expanders are unused product terms that can be allocated to a neighboring macrocell to implement fast, complex logic functions. Parallel expanders allow up to 20 product terms to directly feed the macrocell OR logic, with five product terms provided by the macrocell and 15 parallel expanders provided by neighboring macrocells in the LAB.
The compiler can allocate up to three sets of up to five parallel expanders to the macrocells that require additional product terms. Each set of five parallel expanders incurs a small, incremental timing delay (t example, if a macrocell requires 14 product terms, the Compiler uses the five dedicated product terms within the macrocell and allocates two sets of parallel expanders; the first set includes five product terms, and the second set includes four product terms, increasing the total delay by 2 ×

Two groups of eight macrocells within each LAB (e.g., macrocells 1 through 8 and 9 through 16) form two chains to lend or borrow parallel expanders. A macrocell borrows parallel expanders from lower­numbered macrocells. For example, macrocell 8 can borrow parallel expanders from macrocell 7, from macrocells 7 and 6, or from macrocells 7, 6, and 5. Within each group of eight, the lowest-numbered macrocell can only lend parallel expanders, and the highest-numbered macrocell can only borrow them. Figure 4 shows how parallel expanders can be borrowed from a neighboring macrocell.

Programmable Interconnect Array

Logic is routed between LABs on the PIA. This global bus is a programmable path that connects any signal source to any destination on the device. All MAX 7000A dedicated inputs, I/O pins, and macrocell outputs feed the PIA, which makes the signals available throughout the entire device. Only the signals required by each LAB are actually routed from the PIA into the LAB. Figure 5 shows how the PIA signals are routed into the LAB. An EEPROM cell controls one input to a 2-input AND gate, which selects a PIA signal to drive into the LAB.
Figure 5. MAX 7000A PIA Routing
To LAB
PIA Signals
While the routing delays of channel-based routing schemes in masked or field-programmable gate arrays (FPGAs) are cumulative, variable, and path-dependent, the MAX 7000A PIA has a predictable delay. The PIA makes a design’s timing performance easy to predict.

I/O Control Blocks

The I/O control block allows each I/O pin to be individually configured for input, output, or bidirectional operation. All I/O pins have a tri-state buffer that is individually controlled by one of the global output enable signals or directly connected to ground or VCC. Figure 6 shows the I/O control block for MAX 7000A devices. The I/O control block has 6 or 10 global output enable signals that are driven by the true or complement of two output enable signals, a subset of the I/O pins, or a subset of the I/O macrocells.

When the tri-state buffer control is connected to ground, the output is tri-stated (high impedance) and the I/O pin can be used as a dedicated input. When the tri-state buffer control is connected to VCC, the output is enabled.
The MAX 7000A architecture provides dual I/O feedback, in which macrocell and pin feedbacks are independent. When an I/O pin is configured as an input, the associated macrocell can be used for buried logic.

SameFrame Pin-Outs

MAX 7000A devices support the SameFrame pin-out feature for FineLine BGA packages. The SameFrame pin-out feature is the arrangement of balls on FineLine BGA packages such that the lower-ball­count packages form a subset of the higher-ball-count packages. SameFrame pin-outs provide the flexibility to migrate not only from device to device within the same package, but also from one package to another. A given printed circuit board (PCB) layout can support multiple device density/package combinations. For example, a single board layout can support a range of devices from an EPM7128AE device in a 100-pin FineLine BGA package to an EPM7512AE device in a 256-pin FineLine BGA package.
The Altera design software provides support to design PCBs with SameFrame pin-out devices. Devices can be defined for present and future use. The software generates pin-outs describing how to lay out a board to take advantage of this migration (see Figure 7).

In-System Programma­bility (ISP)
MAX 7000A devices can be programmed in-system via an industry­standard 4-pin IEEE Std. 1149.1 (JTAG) interface. ISP offers quick, efficient iterations during design development and debugging cycles. The MAX 7000A architecture internally generates the high programming voltages required to program EEPROM cells, allowing in-system programming with only a single 3.3-V power supply. During in-system programming, the I/O pins are tri-stated and weakly pulled-up to eliminate board conflicts. The pull-up value is nominally 50 k.
MAX 7000AE devices have an enhanced ISP algorithm for faster programming. These devices also offer an ISP_Done bit that provides safe operation when in-system programming is interrupted. This ISP_Done bit, which is the last bit programmed, prevents all I/O pins from driving until the bit is programmed. This feature is available in EPM7032AE, EPM7064AE, EPM7128AE, EPM7256AE, and EPM7512AE devices only.
ISP simplifies the manufacturing flow by allowing devices to be mounted on a printed circuit board (PCB) with standard pick-and-place equipment before they are programmed. MAX 7000A devices can be programmed by downloading the information via in-circuit testers, embedded processors, the Altera BitBlaster serial download cable, ByteBlaster parallel port download cable, ByteBlasterMV parallel port download cable, and MasterBlaster serial/USB communications cable. Programming the devices after they are placed on the board eliminates lead damage on high-pin-count packages (e.g., QFP packages) due to device handling. MAX 7000A devices can be reprogrammed after a system has already shipped to the field. For example, product upgrades can be performed in the field via software or modem.
In-system programming can be accomplished with either an adaptive or constant algorithm. An adaptive algorithm reads information from the unit and adapts subsequent programming steps to achieve the fastest possible programming time for that unit. A constant algorithm uses a pre­defined (non-adaptive) programming sequence that does not take advantage of adaptive algorithm programming time improvements. Some in-circuit testers cannot program using an adaptive algorithm. Therefore, a constant algorithm must be used. MAX 7000AE devices can be programmed with either an adaptive or constant (non-adaptive) algorithm. EPM7128A and EPM7256A device can only be programmed with an adaptive algorithm; users programming these two devices on platforms that cannot use an adaptive algorithm should use EPM7128AE and EPM7256AE devices.
The Jam programming and test language can be used to program MAX 7000A devices with in-circuit testers, PCs, or embedded processors.

Programmable Speed/Power Control

Output Configuration
MAX 7000A devices offer a power-saving mode that supports low-power operation across user-defined signal paths or the entire device. This feature allows total power dissipation to be reduced by 50% or more because most logic applications require only a small fraction of all gates to operate at maximum frequency.
The designer can program each individual macrocell in a MAX 7000A device for either high-speed (i.e., with the Turbo Bit option turned on) or low-power operation (i.e., with the Turbo Bit option turned off). As a result, speed-critical paths in the design can run at high speed, while the remaining paths can operate at reduced power. Macrocells that run at low power incur a nominal timing delay adder (t

MultiVolt I/O Interface

The MAX 7000A device architecture supports the MultiVolt I/O interface feature, which allows MAX 7000A devices to connect to systems with differing supply voltages. MAX 7000A devices in all packages can be set for 2.5-V, 3.3-V, or 5.0-V I/O pin operation. These devices have one set of VCC pins for internal operation and input buffers (VCCINT), and another set for I/O output drivers (VCCIO).
The VCCIO pins can be connected to either a 3.3-V or 2.5-V power supply, depending on the output requirements. When the VCCIO pins are connected to a 2.5-V power supply, the output levels are compatible with
2.5-V systems. When the VCCIO pins are connected to a 3.3-V power supply, the output high is at 3.3 V and is therefore compatible with 3.3-V or 5.0-V systems. Devices operating with V incur a slightly greater timing delay of t always be driven by 2.5-V, 3.3-V, or 5.0-V signals.

Open-Drain Output Option

MAX 7000A devices provide an optional open-drain (equivalent to open-collector) output for each I/O pin. This open-drain output enables the device to provide system-level control signals (e.g., interrupt and write enable signals) that can be asserted by any of several devices. It can also provide an additional wired-OR plane.
Open-drain output pins on MAX 7000A devices (with a pull-up resistor to the 5.0-V supply) can drive 5.0-V CMOS input pins that require a V
3.5 V. When the open-drain pin is active, it will drive low. When the pin is inactive, the trace will be pulled up to 5.0 V by the resistor. The open­drain pin will only drive low or tri-state; it will never drive high. The rise time is dependent on the value of the pull-up resistor and load impedance. The IOL current specification should be considered when selecting a pull-up resistor.

Programmable Ground Pins

Each unused I/O pin on MAX 7000A devices may be used as an additional ground pin. In EPM7128A and EPM7256A devices, utilizing unused I/O pins as additional ground pins requires using the associated macrocell. In MAX 7000AE devices, this programmable ground feature does not require the use of the associated macrocell; therefore, the buried macrocell is still available for user logic.

Slew-Rate Control

The output buffer for each MAX 7000A I/O pin has an adjustable output slew rate that can be configured for low-noise or high-speed performance. A faster slew rate provides high-speed transitions for high-performance systems. However, these fast transitions may introduce noise transients into the system. A slow slew rate reduces system noise, but adds a nominal delay of 4 to 5 ns. When the configuration cell is turned off, the slew rate is set for low-noise performance. Each I/O pin has an individual EEPROM bit that controls the slew rate, allowing designers to specify the slew rate on a pin-by-pin basis. The slew rate control affects both the rising and falling edges of the output signal.

Because MAX 7000A devices can be used in a mixed-voltage environment, they have been designed specifically to tolerate any possible power-up sequence. The V

in any order.
Signals can be driven into MAX 7000AE devices before and during power­up without damaging the device. Additionally, MAX 7000AE devices do not drive out during power-up. Once operating conditions are reached, MAX 7000AE devices operate as specified by the user.
All MAX 7000A devices contain a programmable security bit that controls access to the data programmed into the device. When this bit is programmed, a design implemented in the device cannot be copied or retrieved. This feature provides a high level of design security because programmed data within EEPROM cells is invisible. The security bit that controls this function, as well as all other programmed data, is reset only when the device is reprogrammed.
MAX 7000A devices are fully tested. Complete testing of each programmable EEPROM bit and all internal logic elements ensures 100% programming yield. AC test measurements are taken under conditions equivalent to those shown in Figure 9. Test patterns can be used and then erased during early stages of the production flow.
Figure 9. MAX 7000A AC Test Conditions
Power supply transients can affect AC measurements. Simultaneous transitions of multiple outputs should be avoided for accurate measurement. Threshold tests must not be performed under AC conditions. Large-amplitude, fast-ground­current transients normally occur as the device outputs discharge the load capacitances. When these transients flow through the parasitic inductance between the device ground pin and the test system ground, significant reductions in observable noise immunity can result. Numbers in brackets are for 2.5-V outputs. Numbers without brackets are for
3.3-V outputs.
