The Microchip Technology Inc. 93XX46A/B/C devices are 1K bit low-voltage serial Electrically Erasable PROMs (EEPROM).
This document provides technical specifications for the Microchip Technology 93XX46A/B/C family of low-power CMOS serial Electrically Erasable PROMs (EEPROM). The devices offer a total capacity of 1,000 bits with options for 8-bit or 16-bit word organization depending on the specific part number and ORG pin configuration. They feature industry-standard 3-wire serial communication, self-timed erase/write cycles, and power-on/off data protection circuitry.
| Capacity | 1K bit |
|---|---|
| Technology | Low-power CMOS |
| Endurance | 1,000,000 E/W cycles |
| Data Retention | > 200 years |
| Clock Frequency (Industrial) | 3 MHz max at 4.5V to 5.5V |
| Operating Temperature (Industrial) | -40°C to +85°C |
The word size can be selected as either 8-bit or 16-bit depending on the external logic levels driving the ORG pin.
The DO pin indicates the status; a low level on DO means programming is in progress, while a high level means the device is ready.
