HM-6642 March 1997 512 x 8 CMOS PROM Description The HM-6642 is a 512 x 8 CMOS NiCr fusible link Programmable Read Only Memory in the popular 24 pin, byte wide pinout. Synchronous circuit design techniques combine with CMOS processing to give this device high speed performance with very low power dissipation. On-chip address latches are provided, allowing easy interfacing with recent generation microprocessors that use multiplexed address/data bus structures, such as the 8085. The output enable controls, both active low and active high, further simplify microprocessor system interfacing by allowing output data bus control independent of the chip enable control.
