The M24C02-RDS6G is a 2Kbit serial EEPROM from STMicroelectronics organized as 256 x 8 bits, accessed through an I²C interface at clock frequencies up to 400 kHz. The 900 ns access time and 5 ms write cycle per word or page set the timing budget for the host controller's polling loop — the device signals completion on the acknowledge bit, so the firmware must wait the full write cycle before attempting the next command.
Package options and board-fit
The supplier device package is 8-MSOP, with the package / case also listed as 8-TSSOP, 8-MSOP (0.118", 3.00mm Width). The 8-MSOP footprint is a standard 3×3 mm body with 0.65 mm pitch — the same land pattern serves both MSOP and TSSOP variants, so a single PCB layout accepts either package from the same reel. Surface-mount assembly with a standard reflow profile for lead-free solder (260°C peak) is compatible. The MSOP package has an exposed pad on the bottom — the datasheet recommends a thermal via array under the pad for heat sinking in high-temperature environments, though the 2Kbit density rarely generates enough self-heating to require it.
STMicroelectronics lists the M24C02-RDS6G as Obsolete. For a BOM that requires this exact 8-MSOP package and 2Kbit density, the M24C02 family (base product number M24C02) includes multiple package and temperature variants — the RDS6G suffix denotes the 8-MSOP package and industrial temperature range. A cross-reference to a different suffix (e.g., the 8-TSSOP variant) would require a PCB footprint change if the land pattern differs.
