8 Kbit I²C EEPROM for parameter storage
The STMicroelectronics M24C08-RDW6TP is an 8Kbit serial EEPROM organized as 1K x 8 bits, accessed over an I²C bus at up to 400 kHz. It stores configuration data, calibration constants, and device identity in designs where non-volatile memory is needed without battery backup. The 900 ns access time is the random-read cycle — sequential reads run at the bus clock rate, so throughput depends on the master's addressing overhead.
Write cycle and endurance context
Page and word writes complete in 5 ms typical. For a 1K x 8 array, that means a full-memory rewrite takes roughly 40 ms if the master pages efficiently. The EEPROM technology supports 1 million write cycles per byte — adequate for calibration updates and event logs, not for high-frequency data logging.
