Intel PE21040-12 is a 4M x 1 Fast Page Mode DRAM utilizing CMOS technology. This component offers an access time of 120ns and supports multiple refresh modes, including RAS-only, CAS-before-RAS, and hidden refresh cycles, with 1024 refresh cycles. The memory organization is 4M words by 1-bit, with separate I/O. Operating within a temperature range of 0°C to 70°C, it requires a supply voltage of 5V (±10%). The PE21040-12 is housed in a 20-pin SOJ (Small Outline J-Lead) package, designed for surface mounting. Its characteristics make it suitable for applications in memory systems requiring efficient data access.
