Advanced Micro Devices AM27256 series OTP ROM, part number AM27256-20DE, offers 262144 bits of memory organized as 32K words by 8 bits. This NMOS technology device features a maximum access time of 200ns and utilizes a CDIP28 package with through-hole mounting. The component operates asynchronously with a common I/O type and 3-state output characteristics. It requires a nominal supply voltage of 5V, with a range of 4.5V to 5.5V, and a programming voltage of 12.5V. Designed for demanding applications, this ROM is suitable for use in industrial, defense, and legacy system designs requiring reliable, non-volatile storage. The ceramic, glass-sealed package ensures robust performance across an operating temperature range of -55°C to +125°C.
