description
The CMOS PLD devices feature variable product terms, flexible outputs, and virtually zero standby power. It
combines TI’s EPIC (Enhanced Processed Implanted CMOS) process with ultraviolet-light-erasable EPROM
technology. Each output has an output logic macrocell (OLM) configuration allowing for user definition of the
output type. This device provides reliable, low-power substitutes for numerous high-performance TTL PLDs with
gate complexities between 300 and 800 gates.
The TICPAL22V10Z has 12 dedicated inputs and 10 user-definable outputs. Individual outputs can be
programmed as registered or combinational and inverting or noninverting as shown in the OLM diagram. These
ten outputs are enabled through the use of individual product terms
The variable product-term distribution on this device removes rigid limitation to a maximum of eight product
terms per output. This technique allocates from 8 to 16 logical product terms to each output for an average of
12 product terms per output. The variable allocation of product terms allows for far more complex functions to
be implemented in this device than in previously available devices.
With features such as the programmable OLMs and the variable product-term distribution, the TICP AL22V10Z
offers quick design and development of custom LSI functions. Since each of the ten output pins may be
individually configured as inputs on either a temporary or permanent basis, functions requiring up to 21 inputs
and a single output or down to 12 inputs and 10 outputs can be implemented with this device.
Design complexity is enhanced by the addition of synchronous set and asynchronous reset product terms.
These functions are common to all registers. When the synchronous set product term is a logic 1, the output
registers are loaded with a logic 1 on the next low-to-high clock transition. When the asynchronous reset product
term is a logic 1, the output registers are loaded with a logic 0 independently of the clock. The output logic level
after set or reset will depend on the polarity selected during programming.
Output registers of this device can be preloaded to any desired state during testing, thus allowing for full logical
verification during product testing.
The TICP AL22V10Z has internal electrostatic discharge (ESD) protection circuits and has been classified with
a 2000-V ESD rating tested under MIL-STD-883C, Method 3015.6. However, care should be exercised in
handling these devices, as exposure to ESD may result in a degradation of the device parametric performance.
The floating-gate programmable cells allow the devices to be fully programmed and tested before assembly to
assure high field programming yield and functionality . They are then erased by ultraviolet light before packaging.
The TICPAL22V10Z-25C is characterized for operation from 0°C to 75°C. The TICPAL22V10Z-30I is
characterized for operation from –40°C to 85°C.
design security
The ’PAL22V10Z contains a programmable design security cell. Programming this cell will disable the read
verify and programming circuitry protecting the design from being copied. The security cell is usually
programmed after the design is finalized and released to production. A secured device will verify as if every
location in the device is programmed. Because programming is accomplished by storing an invisible charge
instead of opening a metal link, the ’22V10Z cannot be copied by visual inspection. Once a secured device is
fully erased, it can be reprogrammed to any desired configuration.

output logic macrocell (OLM) description
A great amount of architectural flexibility is provided by the user-configurable macrocell output options. The
macrocell consists of a D-type flip-flop and two select multiplexers. The D-type flip-flop operates like a standard
TTL D-type flip-flop. The input data is latched on the low-to-high transition of the clock input. The Q and Q outputs
are made available to the output select multiplexer. The asynchronous reset and synchronous set controls are
available in all flip-flops.
The select multiplexers are controlled by programmable cells. The combination of these programmable cells
will determine which macrocell functions are implemented. It is this user control of the architectural structure
that provides the generic flexibility of this device.
