The onsemi CAT28C256LI-15T is a 262,144-bit, parallel interface CMOS EEPROM organized as 32K words by 8 bits. This device offers a maximum access time of 150ns and operates asynchronously with a 5V nominal supply voltage, ranging from 4.5V to 5.5V. It features a 32K word capacity and an 8-bit memory width. The CAT28C256 series supports data polling and a toggle bit for status monitoring. Endurance is rated at 100,000 write cycles, with data retention for a minimum of 100 years. The component is housed in a 28-pin PDIP (Plastic Dual In-line Package) for through-hole mounting. Typical applications include industrial control, automotive systems, and data logging where reliable non-volatile storage is required. The operating temperature range is -40°C to +85°C.
