The Intel M27C64 is a 5V only,65,536-bit ultraviolet erasable and electrically programmable read-only memory
(EPROM). The M27C64 employs advanced CHMOS lI-E Circuitry for systems requiring low power, high per-
formance speeds, and immunity to noise.
Several advanced features have been designed into the M27C64 that allow fast and reliable programming-Quick-Pulse ProgrammingTM, the inteligent ProgrammingTM Algorithm and the inteligent IdentifierTM Mode.
Programming equipment that takes advantage of these innovations will electronically identify the M27C64 and then rapidly program it using an efficient programming method.
The M27C64 also offers extremely low power consumption compared to typical 64K EPROMS. The maximum active current is 25 mA while the maximum standby current is only 140 A. The standby mode lowers power consumption without increasing access time.
Two-line control and JEDEC-approved,28-pin packaging are standard features of all Intel higher density EPROMs. This ensures easy microprocessor interfacing and minimum design efforts when upgrading, adding or choosing between non-volatile memory alternatives.
The highest degree of protection against latch-up is achieved through Intel's unique EPI processing. Preven-
tion of latch-up is provided for stresses up to 100 mA on address and data pins from Vcc -0.5V to VeC+0.5V.
