24LC01-RK

Particle driver for the Microchip 24AA01/24LC01B/24FC01 I2C Serial EEPROM

Yes, it's really small in size (128 byte, 1Kbit) but it it's cheap (US$0.19) in single quantities and it's tiny in the SOT-23/SC-70 package. It's also low-power, 1 uA in standby, so it's great for board identification.

Using the code

Typically you create a global variable for the EEPROM:

EEPROM_24LC01 eeprom;

The first parameter is the Wire interface to use, typically Wire (D0/D1). On the Electron you can also use Wire1 (C4/C5).

There is no address option, as the I2C address is not configurable on the 24xx01.

From setup you typically call:

eeprom.begin();

To read and write data you use the readData and writeData methods:

bool readData(size_t eepromAddr, uint8_t *data, size_t dataLen);
bool writeData(size_t eepromAddr, const uint8_t *data, size_t dataLen);

You can also use get and put like the EEPROM API. This makes it easy to convert code between using the built-in EEPROM and I2C EEPROM as you can use the calls nearly identically.

Release notes

0.0.2 (2024-05-09)

Increased number of completion retries from 10 to 100 as the chip may not be done writing within 10 tries.
Allow configuration of retries using withReadWriteTries() and withCompletionTries().
