MD27C64-35/B

The MD27C64-35/B is designed as one kind 64-Kbit ultraviolet erasable programmable read-only memory which organized as 8K words by 8 bits per word, operates from a single +5 V supply, has a static standby mode, and features fast single address location programming. This device has a CMOS standby mode which reduces the maximum VCC current to 100 mA and also has two control functions, both of which must be logically satisfied in order to obtain data at the outputs.

Features of the MD27C64-35/B are:(1)standard 28-pin DIP, PDIP, and 32-pin PLCC packages;(2)versatile features for simple interfacing:both CMOS and TTL input/output compatibility, two line control functions;(3)high noise immunity;(4)latch-up protected to 100 mA from -1 V to Vcc+1 V;(5)100% flashrite progra-mming: typical programming time of 1 second;(6)±10% power supply tolerance available;(7)single +5 V power supply;(8)JEDEC-approved pinout;(9)low power consumption:20 mA typical CMOS standby current;(10)fast access time:45 ns.

The absolute maximum ratings of the MD27C64-35/B can be summarized as:(1)storage temperature OTP products:-65°C to +125°C;(2)storage temperature all other products:-65°C to +150°C;(3)ambient temperature with power applied:-55°C to +125°C;(4)voltage with respect to Vss (all pins except A9,Vpp,Vcc):-0.6 V to Vcc+0.5 V;(5)voltage with respect to Vss (A9 and Vpp):-0.6 V to +13.5 V;(6)voltage with respect to Vss (Vcc):-0.6 V to +7.0 V.
