DATASHEET X28HC64 FN8109 Rev 4.00 64k, 8k x 8-Bit 5 Volt, Byte Alterable EEPROM June 27, 2016 The X28HC64 is an 8k x 8 EEPROM, fabricated with Intersils Features proprietary, high performance, floating gate CMOS technology. 70ns access time Like all Intersil programmable nonvolatile memories, the X28HC64 is a 5V only device. It features the JEDEC approved Simple byte and page write pinout for byte-wide memories, compatible with industry -Single 5V supply standard RAMs. -No external high voltages or V control circuits P-P The X28HC64 supports a 64-byte page write operation, effectively -Self-timed providing a 32s/byte write cycle, and enabling the entire - No erase before write memory to be typically written in 0.25 seconds. The X28HC64 - No complex programming algorithms also features DATA Polling and Toggle Bit Polling, two methods - No overerase problem providing early end of write detection. In addition, the X28HC64 includes a user-optional software data protection mode that Low power CMOS further enhances Intersils hardware write protect capability. - 40mA active current maximum Intersil EEPROMs are designed and tested for applications 200A standby current maximum requiring extended endurance. Inherent data retention is Fast write cycle times greater than 100 years. - 64-byte page write operation - Byte or page write cycle: 2ms typical - Complete memory rewrite: 0.25s typical - Effective byte write cycle time: 32s typical Software data protection End of write detection - DATA polling -Toggle bit High reliability - Endurance: 100,000 cycles - Data retention: 100 years JEDEC approved byte-wide pinout Pb-free available (RoHS compliant) Pin Configurations X28HC64 X28HC64 (28 LD PDIP, SOIC) (32 LD PLCC) TOP VIEW TOP VIEW 1 28 V NC CC 2 27 A WE 12 4 3 2 1 32 31 30 3 NC A 26 7 A 5 29 A 6 8 4 25 A A 8 6 A 6 28 A 5 9 5 24 A A 9 5 A 7 27 A 4 11 A A 6 23 11 4 A 8 26 NC 3 7 22 A OE X28HC64 3 X28HC64 A 9 25 OE 2 8 21 A A 10 2 A 10 24 A 10 1 A 9 20 CE 1 11 23 CE A 0 10 19 I/O A 0 7 12 22 I/O NC 7 I/O 11 18 I/O 0 6 13 21 I/O I/O 0 6 I/O I/O 14 15 16 17 18 19 20 12 17 1 5 13 16 I/O I/O 4 2 V 14 15 I/O SS 3 FN8109 Rev 4.00 Page 1 of 18 June 27, 2016 I/ O A 7 1 A I/O 12 2 V NC SS NC NC I/O V 3 CC I/O WE 4 I/O NC 5X28HC64 Ordering Information TEMPERATURE ACCESS TIME PKG.
