The Microchip Technology 27C256-20-J is a 32K x 8 bit, 262144 bit CMOS Electrically Programmable Read-Only Memory. This device features a maximum access time of 200ns and operates from a single 5V supply with a tolerance of 4.5V to 5.5V. The 27C256-20-J utilizes a 28-pin Ceramic Dual In-line Package (CDIP28) with through-hole mounting and a 2.54mm terminal pitch. Its asynchronous operating mode and 3-state output characteristics are suitable for applications requiring reliable data storage and retrieval. Typical standby current is 100µA, with a maximum supply current of 25mA. This component is commonly found in industrial control systems, legacy embedded systems, and test and measurement equipment where non-volatile program storage is essential. The 27C256 series offers a robust solution for memory-intensive designs.
