DATASHEET 64k, 8k x 8-Bit 5 Volt, Byte Alterable EEPROM X28HC64 Features The X28HC64 is an 8k x 8 EEPROM, fabricated with Intersils 70ns access time proprietary, high performance, floating gate CMOS technology. Simple byte and page write Like all Intersil programmable nonvolatile memories, the -Single 5V supply X28HC64 is a 5V only device. It features the JEDEC approved -No external high voltages or V control circuits P-P pinout for byte-wide memories, compatible with industry -Self-timed standard RAMs. - No erase before write The X28HC64 supports a 64-byte page write operation, effectively - No complex programming algorithms providing a 32s/byte write cycle, and enabling the entire - No overerase problem memory to be typically written in 0.25 seconds. The X28HC64 also features DATA Polling and Toggle Bit Polling, two methods Low power CMOS providing early end of write detection. In addition, the X28HC64 - 40mA active current maximum includes a user-optional software data protection mode that 200A standby current maximum further enhances Intersils hardware write protect capability. Fast write cycle times Intersil EEPROMs are designed and tested for applications - 64-byte page write operation requiring extended endurance. Inherent data retention is - Byte or page write cycle: 2ms typical greater than 100 years. - 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 WE A 12 4 3 2 1 32 31 30 3 26 NC A 7 A 5 A 29 6 8 A 4 25 A 8 6 A 6 28 A 5 9 A 5 24 A 9 5 A 7 27 A 4 11 6 23 A A 11 4 A 8 26 NC 3 A 7 22 OE X28HC64 3 X28HC64 OE A 9 25 2 A 8 21 A 10 2 A 10 24 A 1 10 A 9 20 CE 1 A 11 23 CE 0 A 10 19 I/O 7 0 12 22 I/O NC 7 I/O 11 18 I/O 6 0 I/O 13 21 I/O 0 6 I/O 12 17 I/O 14 15 16 17 18 19 20 1 5 I/O 13 16 I/O 4 2 V 14 15 I/O SS 3 June 27, 2016 CAUTION: These devices are sensitive to electrostatic discharge follow proper IC Handling Procedures. 1 1-888-INTERSIL or 1-888-468-3774 Copyright Intersil Americas LLC 2005, 2006, 2009, 2015, 2016.
