The Advanced Micro Devices AM27C256-90EI is a 256 Kbit (32K x 8) CMOS OTP ROM. This component offers a maximum access time of 90ns, operating from a 5V supply. It features asynchronous operation and 3-state outputs. The device is housed in a 32-lead PDSO package (JESD-30 Code R-PDSO-G32, TSOP1) with a terminal pitch of 0.5mm, suitable for surface mounting. Typical applications for this type of memory include embedded systems, industrial control, and legacy system designs requiring non-volatile program storage. The operating temperature range is -40°C to +85°C.
