GENERAL DESCRIPTION

The MACH110 is a member of AMD’s high-performance EE CMOS MACH 1 family. This device has approximately three times the logic macrocell capability of the popular PAL22V10 without loss of speed.

The MACH110 consists of two PAL blocks interconnected by a programmable switch matrix. The two PAL blocks are essentially “PAL22V16” structures complete with product-term arrays and programmable macrocells. The switch matrix connects the PAL blocks to each other and to all input pins, providing a high degree of connectivity between the fully-connected PAL blocks. This allows designs to be placed and routed efficiently.

■ 32 Outputs

■ 32 Flip-flops; 2 clock choices

■ 2 “PAL22V16” Blocks

■ Pin-compatible with MACH111, MACH210,

MACH211, MACH215

The MACH110 macrocell provides either registered or combinatorial outputs with programmable polarity. If a registered configuration is chosen, the register can be configured as D-type or T-type to help reduce the number of product terms. The register type decision can be made by the designer or by the software. All macrocells can be connected to an I/O cell. If a buried macrocell is desired, the internal feedback path from the macrocell can be used, which frees up the I/O pin for use as an input.

FUNCTIONAL DESCRIPTION

The MACH110 consists of two PAL blocks connected by a switch matrix. There are 32 I/O pins and 6 dedicated input pins feeding the switch matrix. These signals are distributed to the two PAL blocks for efficient design implementation. There are two clock pins that can also be used as dedicated inputs.

The PAL Blocks

Each PAL block in the MACH110 (Figure 1) contains a 64-product-term logic array, a logic allocator, 16 macrocells and 16 I/O cells. The switch matrix feeds each PAL block with 22 inputs. This makes the PAL block look effectively like an independent “PAL22V16”.

There are four additional output enable product terms in each PAL block. For purposes of output enable, the 16 I/O cells are divided into 2 banks of 8 macrocells. Each bank is allocated two of the output enable product terms.

An asynchronous reset product term and an asynchronous preset product term are provided for flip-flop initialization. All flip-flops within the PAL block are initialized together.

The Switch Matrix

The MACH110 switch matrix is fed by the inputs and feedback signals from the PAL blocks. Each PAL block provides 16 internal feedback signals and 16 I/O feedback signals. The switch matrix distributes these signals back to the PAL blocks in an efficient manner that also provides for high performance. The design software automatically configures the switch matrix when fitting a design into the device.

The Product-Term Array

The MACH110 product-term array consists of 64 product terms for logic use, and 6 special-purpose product terms. Four of the special-purpose product terms provide programmable output enable, one provides asynchronous reset, and one provides a synchronous preset. Two of the output enable product terms are used for the first eight I/O cells; the other two control the last eight macrocells.

The Logic Allocator

The logic allocator in the MACH110 takes the 64 logic product terms and allocates them to the 16 macrocells as needed. Each macrocell can be driven by up to 12 product terms. The design software automatically configures the logic allocator when fitting the design into the device.

Table 1 illustrates which product term clusters are available to each macrocell within a PAL block. Refer to Figure 1 for cluster and macrocell numbers.

The Macrocell

The MACH110 macrocells can be configured as either registered or combinatorial, with programmable polarity. The macrocell provides internal feedback whether configured as registered or combinatorial. The flip-flops can be configured as D-type or T-type, allowing for product-term optimization.

The flip-flops can individually select one of two clock pins, which are also available as data inputs. The registers are clocked on the LOW-to-HIGH transition of the clock signal. The flip-flops can also be asynchronously initialized with the common asynchronous reset and preset product terms.

The I/O Cell

The I/O cell in the MACH110 consists of a three-state output buffer. The three-state buffer can be configured in one of three ways: always enabled, always disabled, or controlled by a product term. If product term control is chosen, one of two product terms may be used to provide the control. The two product terms that are available are common to eight I/O cells. Within each PAL block, two product terms are available for selection by the first eight three-state outputs; two other product terms are available for selection by the last eight three-state outputs.

These choices make it possible to use the macrocell as an output, an input, a bidirectional pin, or a three-state output for use in driving a bus.
