1 / 13 page CAT28C65B 1 Doc. No. 1009, Rev. E © 2005 by Catalyst Semiconductor, Inc. Characteristics subject to change without notice CAT28C65B 64K-Bit CMOS PARALLEL EEPROM FEATURES I Fast read access times: – 90/120/150ns I Low power CMOS dissipation: – Active: 25 mA max. – Standby: 100 µA max. I Simple write operation: – On-chip address and data latches – Self-timed write cycle with auto-clear I Fast write cycle time: – 5ms max I CMOS and TTL compatible I/O I Hardware and software write protection I Commercial, industrial and automotive temperature ranges I Automatic page write operation: – 1 to 32 bytes in 5ms – Page load timer I End of write detection: – Toggle bit – DATA DATA DATA DATA DATA polling – RDY/ BUSY BUSY BUSY BUSY BUSY I 100,000 program/erase cycles I 100 year data retention DESCRIPTION The CAT28C65B is a fast, low power, 5V-only CMOS parallel EEPROM organized as 8K x 8-bits. It requires a simple interface for in-system programming. On-chip address and data latches, self-timed write cycle with auto-clear and VCC power up/down write protection eliminate additional timing and protection hardware. DATA Polling, a RDY/BUSY pin and Toggle status bits signal the start and end of the self-timed write cycle. Additionally, the CAT28C65B features hardware and software write protection. The CAT28C65B is manufactured using Catalyst’s advanced CMOS floating gate technology. It is designed to endure 100,000 program/erase cycles and has a data retention of 100 years. The device is available in JEDEC- approved 28-pin DIP, 28-pin TSOP, 28-pin SOIC or 32- pin PLCC packages. BLOCK DIAGRAM Doc. No. 1009, Rev. E ALO GEN FR TM LEAD FREE ADDR. BUFFER & LATCHES ADDR.
