Functional Description (continued) Power-Up Reset The PALCE16V8 is executed in a 20-pin 300-mil molded DIP, a 300-mil cerdip, a 20-lead square ceramic leadless chip carrier, and a 20-lead square plastic leaded chip carrier. All registers in the PALCE16V8 power-up to a logic LOW for predictable system initialization. For each register, the associated output pin will be HIGH due to active-LOW outputs. The device provides up to 16 inputs and 8 outputs. The PALCE16V8 can be electrically erased and reprogrammed. The programmable macrocell enables the device to function as a superset to the familiar 20-pin PLDs such as 16L8, 16R8, 16R6, and 16R4. Electronic Signature The PALCE16V8 features 8 product terms per output and 32 input terms into the AND array. The first product term in a macrocell can be used either as an internal output enable control or as a data product term. Security Bit There are a total of 18 architecture bits in the PALCE16V8 macrocell; two are global bits that apply to all macrocells and 16 that apply locally, two bits per macrocell. The architecture bits determine whether the macrocell functions as a register or combinatorial with inverting or noninverting output. The output enable control can come from an external pin or internally from a product term. The output can also be permanently enabled, functioning as a dedicated output or permanently disabled, functioning as a dedicated input. Feedback paths are selectable from either the input/output pin associated with the macrocell, the input/output pin associated with an adjacent pin, or from the macrocell register itself. An electronic signature word is provided in the PALCE16V8 that consists of 64 bits of programmable memory that can contain user-defined data. A security bit is provided that defeats the readback of the internal programmed pattern when the bit is programmed. Low Power The Cypress PALCE16V8 provides low-power operation through the use of CMOS technology, and increased testability with Flash reprogrammability. Product Term Disable Product Term Disable (PTD) fuses are included for each product term. The PTD fuses allow each product term to be individually disabled.

These are absolute values with respect to device ground. All overshoots due to system or tester noise are included. 4. VIL (Min.) is equal to -3.0V for pulse durations less than 20 ns. 5. The leakage current is due to the internal pull-up resistor on all pins. 6. Not more than one output should be tested at a time. Duration of the short circuit should not be more than one second. VOUT = 0.5V has been chosen to avoid test problems caused by tester ground degradation. 7. Tested initially and after any design or process changes that may affect these parameters.

Notes: 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. This parameter is measured as the time after OE pin or internal disable input disables or enables the output pin. 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. 11. This specification indicates the guaranteed maximum frequency at which a state machine configuration with external feedback can operate. 12. This specification indicates the guaranteed maximum frequency at which the device can operate in data path mode. 13. This specification indicates the guaranteed maximum frequency at which a state machine configuration with internal only feedback can operate. 14. This parameter is calculated from the clock period at fMAX internal (1/fMAX3) as measured (see Note 7 above) minus tS.
