Microchip Technology's 28C256-20-K is a 262Kbit CMOS Electrically Erasable Programmable Read-Only Memory organized as 32K words by 8 bits. This parallel interface EEPROM features a maximum access time of 200ns and a 5V programming voltage. The device supports data polling and toggle bit functions for efficient read and write operations, with a write cycle time of 2ms. Its endurance rating is 10,000 write cycles. The 28C256 series is suitable for applications in industrial control, automotive systems, and data logging where non-volatile data storage is critical. This component is housed in a 32-lead Ceramic Quad Flat No-Lead (CQFN) package, adhering to JESD-30 R-CQCC-N32 specifications, with a terminal pitch of 1.27mm. The operating temperature range is 0°C to 70°C.
