The Advanced Micro Devices AM27C040-255JI is a 4-Mbit, single-supply, high-performance CMOS 512K x 8-bit One-Time Programmable (OTP) Read-Only Memory. This component features an access time of 250 ns, enabling fast data retrieval for demanding applications. Operating from a single 5V supply (4.75V to 5.25V), it offers a low standby current of 100 µA and a maximum operating current of 40 mA. The device utilizes CMOS technology for reduced power consumption and enhanced noise immunity.
Designed with a PQCC32 package (JESD-30 Code R-PQCC-J32), this surface-mount component is suitable for high-density board layouts. Its memory organization is 512K words by 8 bits, providing a total capacity of 4,194,304 bits. The AM27C040 series is commonly employed in industrial control systems, telecommunications infrastructure, and consumer electronics where reliable, non-volatile program storage is critical. The output characteristics are 3-state, facilitating bus compatibility.
