Advanced Micro Devices AM90C255 series NIBBLE MODE DRAM, part number AM90C255-12PC, offers a 256K x 1 memory organization with a maximum access time of 120ns. This CMOS component utilizes nibble mode for enhanced data transfer efficiency and features RAS-only refresh for simplified refresh cycles. The separate I/O architecture and 3-state output characteristics are designed for asynchronous operation. Packaged in a 16-lead PDIP (R-PDIP-T16) with a 2.54mm terminal pitch, this through-hole component operates within a supply voltage range of 4.5V to 5.5V and an ambient temperature range of 0°C to 70°C. Its applications span industrial control systems and legacy computing platforms requiring reliable memory solutions.
