Description

The ST93CS56 and ST93CS57 are 2K bit Electrically Erasable ProgrammableMemory (EEPROM) fabricatedwith SGS-THOMSON'sHigh Endurance Single Polysilicon CMOS technology. The memory is accessed through a serial input D and output Q.The 2K bit memory is organized as 128 x 16 bit words.Thememory is accessed by a set of instructions which include Read,Write, PageWrite, Write All and instructions of the ST93CS57 used to set the memory protection.A Read instruction loads the address of the first word to be read into an internal address pointer.
