Its 64K of memory is organized 8,192 words by 8 bits. Manufactured with Atmel’s advanced nonvolatile CMOS technology, the device offers access times to 200 ns with power dissipation less than 30 mW. When the device is deselected the standby current is less than 50 µA. continued Pin Configurations Pin Name A0 - A12 CE OE WE I/O0 - I/O7 RDY/BUSY NC DC Function Addresses Chip Enable Output Enable Write Enable Data Inputs/Outputs Ready/Busy Output No Connect Don’t Connect PLCC Top View PDIP, SOIC Top View RDY/BUSY 1 A12 2 A7 3 A6 4 A5 5 A4 6 A3 7 A2 8 A1 9 A0 10 I/O0 11 I/O1 12 I/O2 13 GND 14 28 VCC 27 WE 26 NC 25 A8 24 A9 23 A11 22 OE 21 A10 20 CE 19 I/O7 18 I/O6 17 I/O5 16 I/O4 15 I/O3 TSOP Top View 4 A7 3 A12 2 RDY/BUSY 1 DC 32 VCC 31 WE 30 NC A6 5 A5 6 A4 7 A3 8 A2 9 A1 10 A0 11 NC 12 I/O0 13 29 A8 28 A9 27 A11 26 NC 25 OE 24 A10 23 CE 22 I/O7 21 I/O6 OE 1 A11 2 A9 3 A8 4 NC 5 WE 6 VCC 7 RDY/BUSY 8 A12 9 A7 10 A6 11 A5 12 A4 13 A3 14 28 A10 27 CE 26 I/O7 25 I/O6 24 I/O5 23 I/O4 22 I/O3 21 GND 20 I/O2 19 I/O1 18 I/O0 17 A0 16 A1 15 A2 64K 8K x 8 Battery-Voltage Parallel EEPROMs AT28BV64 I/O1 14 I/O2 15 VSS 16 DC 17 I/O3 18 I/O4 19 I/O5 20 The AT28BV64 is 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. Following the initiation of a write cycle, the device will go to a busy state and automatically clear and write the latched data using an internal control timer. The device includes two methods for detecting the end of a write cycle, level detection of RDY/BUSY and 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 28BV64 has additional features to ensure high quality and manufacturability. The device utilizes error correction internally for extended endurance and for improved data retention characteristics. An extra 32-bytes of EEPROM are available for device identification or tracking.
