93C46CB3
93C46CB3 is ST93C46CB manufactured by STMicroelectronics.
DESCRIPTION
This specification covers a range of 1K bit serial EEPROM products, the ST93C46A,46C,46T specified at 5V±10% and the ST93C47C,47T specified at 3V to 5.5V. In the text, products are referred to as ST93C46. The ST93C46 is a 1K bit Electrically Erasable Programmable Memory (EEPROM) fabricated with SGS-THOMSON’s High Endurance Single Polysilicon CMOS technology. The memory is accessed through a serial input (D) and output (Q). Table 1. Signal Names

Notes: 1. Except for the rating ”Operating Temperature Range”, stresses above those listed in the Table ”Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other conditions above those indicated in the Operating sections of this specification is not implied. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability. Refer also to the SGS-THOMSON SURE Program and other relevant quality documents. 2.
