Microchip Technology's AT28BV256-25JJ is a 32K x 8 parallel EEPROM featuring a 250ns asynchronous access time. This CMOS device operates from a 2.7V to 3.6V supply, with a nominal 3V requirement, and supports a wide industrial temperature range of -40°C to +85°C. The AT28BV256 series offers automatic write capabilities and a write cycle time of 10ms maximum. Packaged in a 32-lead PQCC (J-lead) format with a 1.27mm terminal pitch, this surface-mount component is suitable for applications in industrial control, telecommunications, and embedded systems requiring non-volatile data storage. Its memory density is 262144 bits.
