Features
1.
The Atmel AT27C2048 is a low-power, high-performance 2,097,152-bit, one-time pro-
grammable, read-only memory (OTP EPROM) organized as 128K by 16 bits. It requires a
single 5V power supply in normal read mode operation. Any word can be accessed in less
than 55 ns, eliminating the need for speed-reducing WAIT states. The x16 organization
makes this part ideal for high-performance, 16- and 32-bit microprocessor systems.
In read mode, the AT27C2048 typically consumes 15mA. Standby mode supply current is
typically less than 10µA
The AT27C2048 is available in an industry-standard, JEDEC-approved, one-time program-
mable (OTP) PLCC package. The device features two-line control (CE, OE) to eliminate
bus contention in high-speed systems.
With high-density, 128K word storage capability, the AT27C2048 allows firmware to be
stored reliably and to be accessed by the system without the delays of mass storage media.
The AT27C2048 has additional features that ensure high quality and efficient production
use. The rapid programming algorithm reduces the time required to program the part and
guarantees reliable programming. Programming time is typically only 50 µs/word. The Inte-
grated product identification code electronically identifies the device and manufacturer. This
feature is used by industry-standard programming equipment to select the proper pro-
gramming algorithms and voltages.
