AT28C64B-15PU – ATMEL

The AT28C64B-15PU is a 64-kilobit (8K x 8) parallel EEPROM manufactured by ATMEL, packaged in a 28-pin plastic dual in-line package (PDIP). This device features an access time of 150 nanoseconds, specified for read operations. It utilizes a standard parallel interface for data input/output and address decoding, enabling direct memory access with microprocessors and microcontrollers. The AT28C64B incorporates an internal address latch and data latch, simplifying write cycle timing. It operates on a single 5V power supply and offers in-system electrical erasability and programmability, allowing for non-volatile data storage and modification without requiring removal from the circuit. The device supports page write mode, enabling the programming of multiple bytes in a single operation to improve write performance. The AT28C64B-15PU is suitable for applications requiring moderate density, non-volatile memory with relatively fast access times and in-system programmability.
