93LC46B1 PDF Datasheet – 1K Microwire Serial EEPROM

EEPROM stands for Electrically Erasable Programmable Read-Only Memory. It is a type of non-volatile memory used in computers, microcontrollers, and other electronic devices to store data that must be retained even when the power is turned off. EEPROM is a variation of ROM (Read-Only Memory) that can be both programmed and erased electrically.

Part Number: 93LC46B1, 93LC46BI

Function: 1K Microwire Compatible Serial EEPROM

Package: SOIC, DIP 8 Pin Type

The Microchip Technology Inc. 93AA46A / 93LC46B / 93AA46C, 93AA46BI,  93LC46B1 devices are 1Kbit low-voltage serial Electrically Erasable PROMs (EEPROM). Word-selectable devices such as the 93AA46C, 93LC46C or 93C46C are dependent upon external logic levels driving the ORG pin to set word size.

For dedicated 8-bit communication, the 93AA46A, 93LC46A or 93C46A devices are available, while the 93AA46B, 93LC46B and 93C46B devices provide dedicated 16-bit communication.
