The Advanced Micro Devices AM90C255-08PCB is a 256K x 1 bit CMOS DRAM featuring nibble mode operation for enhanced data access. This asynchronous memory component offers an 80ns maximum access time and utilizes RAS-only refresh. Designed with separate I/O, it operates within a 4.5V to 5.5V supply voltage range and is housed in a 16-pin PDIP package suited for through-hole mounting. The AM90C255 series is recognized for its application in embedded systems, industrial control, and consumer electronics requiring reliable memory solutions. The device supports 256 refresh cycles and operates within a 0°C to 70°C temperature range. Its 3-state output characteristic is a key feature for bus interfacing.
