1 / 12 page FINAL Publication# 11407 Rev: G Amendment/0 Issue Date: May 1998 Am27C2048 2 Megabit (128 K x 16-Bit) CMOS EPROM DISTINCTIVE CHARACTERISTICS s Fast access time — Speed options as fast as 55 ns s Low power consumption — 100 µA maximum CMOS standby current s JEDEC-approved pinout — Plug-in upgrade of 1 Mbit EPROM — 40-pin DIP/PDIP — 44-pin PLCC s Single +5 V power supply s ±10% power supply tolerance standard s 100% Flashrite programming — Typical programming time of 16 seconds s Latch-up protected to 100 mA from –1 V to VCC + 1 V s Versatile features for simple interfacing — Both CMOS and TTL input/output compatibility — Two line control functions s High noise immunity GENERAL DESCRIPTION The Am27C2048 is a 2 Mbit, ultraviolet erasable pro- grammable read-only memory. It is organized as 128 K words, operates from a single +5 V supply, has a static standby mode, and features fast single address loca- tion programming. The Am27C2048 is ideal for use in 16-bit microprocessor systems. The device is available in windowed ceramic DIP packages, and plastic one time programmable (OTP) PDIP and PLCC packages. Data can be typically accessed in less than 55 ns, al- lowing high-performance microprocessors to operate without any WAIT states. The device offers separate Output Enable (OE#) and Chip Enable (CE#) controls, thus eliminating bus contention in a multiple bus micro- processor system. AMD’s CMOS process technology provides high speed, low power, and high noise immunity. Typical power consumption is only 125 mW in active mode, and 100 µW in standby mode. All signals are TTL levels, including programming sig- nals. Bit locations may be programmed singly, in blocks, or at random. The device supports AMD’s Flashrite programming algorithm (100 µs pulses), re- sulting in a typical programming time of 16 seconds.
