Description
The AT28C16 is a low-power, high-performance Electrically Erasable and Programmable Read Only Memory with easy to use features. It is a 16K memory organized as 2,048 words by 8 bits. The device is manufactured with Atmel’s reliable nonvolatile CMOS technology.
The AT28C16 can be accessed like a static RAM for the read or write cycles without the need for external components. During a byte write, the address and data are latched internally, freeing the microprocessor address and data bus for other operations. The device has a busy state and automatically clears and writes the latched data using an internal control timer. The end of a write cycle can be determined by DATA POLLING of I/O7. Once the end of a write cycle has been detected, a new access for a read or a write can begin.
The CMOS technology offers fast access times of 150 ns at low power dissipation. When the chip is deselected, the standby current is less than 100 µA. Atmel’s 28C16 has additional features to ensure high quality and manufacturability. The device utilizes error correction internally for extended endurance and improved data retention characteristics. There are extra 32 bytes of EEPROM available for device identification or tracking.
