ST93C56, 56C ST93C57C 2K (128 x 16 or 256 x 8) SERIAL MICROWIRE EEPROM NOT FOR NEW DESIGN 1 MILLION ERASE/WRITE CYCLES, with 40 YEARS DATA RETENTION DUAL ORGANIZATION: 128 x 16 or 256 x 8 BYTE/WORD and ENTIRE MEMORY PROGRAMMING INSTRUCTIONS SELF-TIMED PROGRAMMING CYCLE with AUTO-ERASE READY/BUSY SIGNAL DURING PROGRAMMING SINGLE SUPPLY VOLTAGE: – 4.5V to 5.5V for ST93C56 version – 3V to 5.5V for ST93C57 version SEQUENTIAL READ OPERATION 5ms TYPICAL PROGRAMMING TIME ST93C56, ST93C56C, ST93C57C are replaced by the M93C56 DESCRIPTION This specification covers a range of 2K bit serial EEPROM products, the ST93C56, 56C specified at 5V ± 10% and the ST93C57C specified at 3V to 5.5V. In the text, products are referred to as ST93C56. The ST93C56 is a 2K bit Electrically Erasable Programmable Memory (EEPROM) fabricated with SGS-THOMSON’s High EnduranceSingle Polysilicon CMOS technology. The memory is accessed through a serial input (D) and output (Q). The 2K bit memory is divided into either 256 x 8 bit bytes or 128 x 16 bit words. The organization may be selected by a signal applied on the ORG input. Table 1.
