Features
1. Description
The AT28HC64BF is a high-performance electrically-erasable and programmable
read-only memory (EEPROM). Its 64K of memory is organized as 8,192 words by 8
bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device
offers access times to 55 ns with power dissipation of just 220 mW. When the device
is deselected, the CMOS standby current is less than 100 µA.
The AT28HC64BF 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 bytes simultaneously. During a write cycle, the addresses and 1 to
64 bytes of data are internally latched, freeing the address 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.
Atmel’s AT28HC64BF has additional features to ensure high quality and manufactura-
bility. The device utilizes internal error correction for extended endurance and
improved data retention characteristics. An optional software data protection mecha-
nism is available to guard against inadvertent writes. The device also includes an
extra 64 bytes of EEPROM for device identification or tracking.
