AM27C128

FINAL Am27C128 128 Kilobit (16 K x 8-Bit) CMOS EPROM DISTINCTIVE CHARACTERISTICS s Fast access time — Speed options as fast as 45 ns s Low power consumption — 20 µA typical CMOS standby current s JEDEC-approved pinout s Single +5 V power supply s ±10% power supply tolerance standard s 100% Flashrite™ programming — Typical programming time of 2 seconds s Latch-up protected to 100 mA from –1 V to VCC + 1 V s High noise immunity s Versatile features for simple interfacing — Both CMOS and TTL input/output compatibility — Two line control functions s Standard 28-pin DIP, PDIP, and 32-pin PLCC packages GENERAL DESCRIPTION The Am27C128 is a 128-Kbit, ultraviolet erasable programmable rea d-only me mory. It is orga nized as 16 Kwords by 8 bits per word, operates from a single +5 V supply, has a s tatic standby m ode, and features fast single addr ess l ocation p rogramming . P roducts are available in w indowed ceramic DIP packages, as well as pl astic one time pr ogrammab le (O TP) P DIP and PLCC packages. Data can be t ypically accessed in les s than 45 ns, allowing high-performance microprocessors to operate without any WAIT s tates. Th e de vice offers separate Output Enable (OE#) and Chip Enable (CE#) controls, thus eliminating bus contention in a multiple bus microprocessor system.
