X28HC64JI-12

The X28HC64JI-12 is designed as an 8K x 8 EEPROM, fabricated with intersil's proprietary, high performance, floating gate CMOS technology. Like all Intersil programmable nonvolatile memories, the X28HC64 is a 5V only device. It features the JEDEC approved pinto for byte-wide memories, compatible with industry standard RAMs.

X28HC64JI-12 has eight features. (1) 70ns access time. (2) Simple byte and page write which means single 5V supply, no external high voltages or VPP control circuits, self-timed, no erase before write, no complex programming algorithms and no overerase problem. (3) Low power CMOS which means 40mA active current max and 200A standby current max. (4) Fast write cycle times which means 64-byte page write operation, byte or page write cycle: 2ms typical, complete memory rewrite: 0.25 sec typical and effective byte write cycle time: 32s typical. (5) Software data protection. (6) End of write detection which means DATA polling and toggle bit. (7) High reliability which means endurance: 1 million cycles and data retention: 100 years. (8) JEDEC approved byte-wide pin out. That are all the main features.

Some absolute maximum ratings of X28HC64JI-12 have been concluded into several points as follow. (1) Its temperature under bias would be from -65°C to +135°C. (2) Its storage temperature range would be from -65°C to +150°C. (3) Its voltage on any pin with respect to Vss would be from -1V to 7V. (4) Its DC output current would be 5mA. (5) Its lead temperature (soldering, 10 seconds) would be 300°C. It should be noted that stresses above those listed under "absolute maximum ratings" may cause permanent damage to the device.

Also some DC electrical characteristics about X28HC64JI-12. (1) Its Vcc current (active) (TTL inputs) would be typ 15mA and max 40mA. (2) Its Vcc current (standby) (TTL inputs) would be typ 1mA and max 2mA. (3) Its Vcc current (standby) (CMOS inputs) would be typ 100uA and max 200uA. And so on.
