PALC22V10D
Flash Erasable, Reprogrammable CMOS PAL(R) Device
Features
* Advanced second-generation PAL architecture * Low power -- 90 mA max. commercial (10 ns) -- 130 mA max. commercial (7.5 ns) * CMOS Flash EPROM technology for electrical erasability and reprogrammability * Variable product terms -- 2 x(8 through 16) product terms * User-programmable macrocell -- Output polarity control -- Individually selectable for registered or combinatorial operation * Up to 22 input terms and 10 outputs * DIP, LCC, and PLCC available -- 7.5 ns commercial version 5 ns tCO 5 ns tS 7.5 ns tPD 133-MHz state machine -- 10 ns military and industrial versions 6 ns tCO 6 ns tS 10 ns tPD 110-MHz state machine -- 15-ns commercial and military versions -- 25-ns commercial and military versions * High reliability -- Proven Flash EPROM technology 100% programming and functional testing vides the capability of defining the architecture of each output individually. Each of the 10 potential outputs may be specified as "registered" or "combinatorial." Polarity of each output may also be individually selected, allowing complete flexibility of output configuration. Further configurability is provided through "array" configurable "output enable" for each potential output. This feature allows the 10 outputs to be reconfigured as inputs on an individual basis, or alternately used as a combination I/O controlled by the programmable array. PALC22V10D features a variable product term architecture. There are 5 pairs of product term sums beginning at 8 product terms per output and incrementing by 2 to 16 product terms per output. By providing this variable structure, the PAL C 22V10D is optimized to the configurations found in a majority of applications without creating devices that burden the product term structures with unusable product terms and lower performance. Additional features of the Cypress PALC22V10D include a synchronous preset and an asynchronous reset product term. These product terms are common to all macrocells, eliminating the need to dedicate standard product terms for initialization functions. The device automatically resets upon power-up. The PALC22V10D, featuring programmable macrocells and variable product terms, provides a device with the flexibility to implement logic functions in the 500- to 800-gate-array complexity. Since each of the 10 output pins may be individually configured as inputs on a temporary or permanent basis, functions requiring up to 21 inputs and only a single output and down to 12 inputs and 10 outputs are possible. The 10 potential outputs are enabled using product terms. Any output pin may be permanently selected as an output or arbitrarily enabled as an output and an input through the selective use of individual product terms associated with each output. Each of these outputs is achieved through an individual programmable macrocell. These macrocells are programmable to provide a combinatorial or registered inverting or non-inverting output. In a registered mode of operation, the output of the register is fed back into the array, providing current status information to the array. This information is available for establishing the next result in applications such as control state machines. In a combinatorial configuration, the combinatorial output or, if the output is disabled, the signal present on the I/O pin is made available to the array. The flexibility provided by both programmable product term control of the outputs and variable product terms allows a significant gain in functional density through the use of programmable logic. Along with this increase in functional density, the Cypress PALC22V10D provides lower-power operation through the use of CMOS technology, and increased testability with Flash reprogrammability.

Functional Description
The Cypress PALC22V10D is a CMOS Flash Erasable second-generation programmable array logic device. It is implemented with the familiar sum-of-products (AND-OR) logic structure and the programmable macrocell. The PALC22V10D is executed in a 24-pin 300-mil molded DIP, a 300-mil cerDIP, a 28-lead square ceramic leadless chip carrier, a 28-lead square plastic leaded chip carrier, and provides up to 22 inputs and 10 outputs. The 22V10D can be electrically erased and reprogrammed. The programmable macrocell pro-

Notes: 7. Part (a) of AC Test Loads and Waveforms is used for all parameters except tER and tEA(+). Part (b) of AC Test Loads and Waveforms is used for tER. Part (c) of AC Test Loads and Waveforms is used for tEA(+). 8. Min. times are tested initially and after any design or process changes that may affect these parameters. 9. This specification is guaranteed for all device outputs changing state in a given access cycle. 10. The test load of part (a) of AC Test Loads and Waveforms is used for measuring tEA(-). The test load of part (c) of AC Test Loads and Waveforms is used for measuring tEA(+) only. Please see part (e) of AC Test Loads and Waveforms for enable and disable test waveforms and measurement reference levels. 11. This parameter is measured as the time after output disable input that the previous output data state remains stable on the output. This delay is measured to the point at which a previous HIGH level has fallen to 0.5 volts below VOH min. or a previous LOW level has risen to 0.5 volts above VOL max. Please see part (e) of AC Test Loads and Waveforms for enable and disable test waveforms and measurement reference levels. 12. This specification indicates the guaranteed maximum frequency at which a state machine configuration with external feedback can operate. 13. This specification indicates the guaranteed maximum frequency at which the device can operate in data path mode. 14. This specification indicates the guaranteed maximum frequency at which a state machine configuration with internal only feedback can operate. 15. This parameter is calculated from the clock period at fMAX internal (1/fMAX3) as measured (see Note above) minus tS. 16. The registers in the PALC22V10D have been designed with the capability to reset during system power-up. Following power-up, all registers will be reset to a logic LOW state. The output state will depend on the polarity of the output buffer. This feature is useful in establishing state machine initialization. To insure proper operation, the rise in VCC must be monotonic and the timing constraints depicted in Power-Up Reset Waveform must be satisfied.
