2 / 25 page 2 ATF1502AS(L) 0995J–PLD–09/02 44-lead TQFP Top View 44-lead PLCC Top View Description The ATF1502AS is a high-performance, high-density complex programmable logic device (CPLD) that utilizes Atmel’s proven electrically-erasable technology. With 32 logic macrocells and up to 36 inputs, it easily integrates logic from several TTL, SSI, MSI, LSI and classic PLDs. The ATF1502AS’s enhanced routing switch matrices increase usable gate count and the odds of successful pin-locked design modifications. The ATF1502AS has up to 32 bi-directional I/O pins and four dedicated input pins, depending on the type of device package selected. Each dedicated pin can also serve as a global control signal, register clock, register reset or output enable. Each of these control signals can be selected for use individually within each macrocell. 1 2 3 4 5 6 7 8 9 10 11 33 32 31 30 29 28 27 26 25 24 23 I/O/TDI I/O I/O GND PD1/I/O I/O TMS/I/O I/O VCC I/O I/O I/O I/O/TDO I/O I/O VCC I/O I/O I/O/TCK I/O GND I/O 7 8 9 10 11 12 13 14 15 16 17 39 38 37 36 35 34 33 32 31 30 29 TDI/I/O I/O I/O GND PD1/I/O I/O I/O/TMS I/O VCC I/O I/O I/O I/O/TDO I/O I/O VCC I/O I/O I/O/TCK I/O GND I/O |
