ATMEL AT28HC256E-70JU EEPROM, 高速, 256 Kbit, 32K x 8位, 并行, 塑料有引线芯片载体, 32 引脚
The is a 256k high-performance Electrically Erasable and Programmable Read-Only Memory EEPROM organized as 32768 words by 8-bit. Manufactured with Atmels advanced nonvolatile CMOS technology, the AT28HC256 offers access times to 70ns with power dissipation of just 440mW. When the AT28HC256 is deselected, the standby current is less than 5mA. The AT28HC256 is accessed like a static RAM for the read or write cycle without the need for external components. The device contains a 64-byte page register to allow writing of up to 64-byte simultaneously. During a write cycle, the address and 1 to 64-byte of data are internally latched, freeing the addresses and data bus for other operations. Following the initiation of a write cycle, the device will automatically write the latched data using an internal control timer. The end of a write cycle can be detected by DATA Polling of I/O7. Once the end of a write cycle has been detected a new access for a read or write can begin.
