1. Description
The Atmel AT27C4096 is a low-power, high-performance, 4,194,304-bit, one-time programmable, read-only memory (OTP EPROM) organized as 256K by 16 bits. It requires a
single 5V power supply in normal read mode operation. Any word can be accessed in less
than 55ns, 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 AT27C4096 typically consumes 15mA. Standby mode supply current is
typically less than 10µA
The AT27C4096 is available in industry-standard, JEDEC-approved, one-time programmable (OTP) PDIP and PLCC packages. The device features two-line control (CE, OE) to
eliminate bus contention in high speed systems.
With high-density 256K word storage capability, the AT27C4096 allows firmware to be
stored reliably and to be accessed by the system without the delays of mass storage media.
The AT27C4096 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 50µs/word. The Integrated product identification code electronically identifies the device and manufacturer. This
feature is used by industry-standard programming equipment to select the proper programming algorithms and voltages.
