It is implemented with the familiar sum-of-products (AND-OR) logic structure and a new concept, the “Programmable Macrocell.” The PALC22V10B is executed in a 24-pin 300-mil molded DIP, a 300-mil windowed 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. When the windowed cerDIP is exposed to UV light, the 22V10B is erased and can then be reprogrammed. The programmable macrocell provides 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 — 15 ns and “20 ns” military 10/15 ns tCO 10/17 ns tS 15/20 ns tPD 50/31 MHz • Up to 22 input terms and 10 outputs Logic Block Diagram (PDIP/CDIP) VSS I 12 11 I I I I I I I I I CP/I 10 9 8 7 6 5 4 3 2 1 PROGRAMMABLE ANDARRAY (132X 44) 8 10 12 14 16 16 14 12 10 8 Macrocell Macrocell Macrocell Macrocell Macrocell Macrocell Macrocell Macrocell Macrocell Reset Macrocell Preset 13 14 15 16 17 18 19 20 21 22 23 24 I I/O9 I/O8 I/O7 I/O6 I/O5 I/O4 I/O3 I/O2 I/O1 I/O0 VCC Cypress Semiconductor Corporation Document #: 38-03018 Rev. *A • 3901 North First Street • San Jose, CA 95134 • 408-943-2600 Revised April 22, 2004 PALC22V10B USE ULTRA37000™ FOR ALL NEW DESIGNS PLCC Top View I I CP/I N/C VCC I/O0 I/O1 I I CP/I N/C VCC I/O0 I/O1 LCC Top View 4 3 2 1 2827 26 I/O2 I/O3 I/O4 N/C I/O5 I/O6 I/O7 I I I N/C I I I 5 6 7 8 9 10 11 25 24 23 22 21 20 121314 1516 171819 I/O2 I/O3 I/O4 N/C I/O5 I/O6 I/O7 I I I I I I I/O9 I/O8 4 3 2 1 282726 25 24 23 22 21 20 19 12131415161718 I/O9 I/O8 5 6 7 8 9 10 11 VSS N/C I I I N/C I I I VSS N/C Pin Configurations Ultra37000 is a trademark of Cypress Semiconductor Corporation.
