The Advanced Micro Devices AM27C400-255JI is a 4 Mbit (256K x 16 bit) CMOS One-Time Programmable (OTP) Read-Only Memory. This device features an asynchronous operating mode with a maximum access time of 250 ns. It operates from a 5V supply voltage (4.75V to 5.25V) and utilizes CMOS technology for low power consumption, with a standby current of 100 µA maximum and a maximum operating current of 40 mA. The AM27C400-255JI is housed in a 44-lead J-leaded ceramic quad flat package (CQFP), designed for surface mounting. Applications for this memory component include industrial control systems, consumer electronics, and telecommunications equipment requiring non-volatile code storage. The memory organization is 256K words by 16 bits, providing a total density of 4,194,304 bits.
