8 Kbit serial EEPROM in a SOT-23-6 — what it stores and how it talks
The Microchip 93LC76AT-I/OT is an 8 Kbit serial EEPROM organized as 1K x 8 bits, communicating over a Microwire bus at up to 3 MHz. It is a non-volatile memory for storing calibration constants, configuration parameters, serial numbers, or small lookup tables in embedded systems.
The Microwire interface uses a simple 3-wire serial bus (CS, SK, DI/DO) that most microcontrollers can bit-bang or drive with a dedicated SPI peripheral — just watch the polarity and protocol because Microwire is not directly SPI-compatible. At 3 MHz the read cycle completes in a few microseconds; the write cycle takes up to 5 ms per word or page, so plan for that latency in your firmware state machine.
Temperature grade — industrial range covers most environments
No need to step up to an automotive-grade part unless your spec calls for AEC-Q100 or 125°C junction.
