Key Differentiators
- Wide supply voltage range down to 1.8V (vs M24C02-WMN6TP)
- Tape and reel packaging for automated assembly (vs M24C02-RMN6P)
- Industrial temperature range (vs M24C02-RMN6TP (commercial grade))
Design Notes
Place pull-up resistors (typically 4.7kΞ©) on the SDA and SCL lines for I2C communication. For 400 kHz operation, ensure the bus capacitance does not exceed 400 pF. Keep traces short and avoid routing near high-noise sources. Connect the WC pin to ground for normal write operations, or to VCC to enable write protection.
Decouple the VCC pin with a 0.1Β΅F ceramic capacitor placed as close as possible to the device. The M24C02-RMN6TP operates from 1.8V to 5.5V, so ensure the supply voltage is within this range. For battery-powered applications, the low standby current (typically 1Β΅A) helps extend battery life.
Ensure the device address pins (A0, A1, A2) are correctly tied to VCC or GND to avoid address conflicts on the I2C bus. The M24C02 uses a 7-bit address with the upper 4 bits fixed as 1010, and the lower 3 bits set by A0-A2. Incorrect address settings will prevent communication with the device.
Compliance Information
RoHS compliant per STMicroelectronics product page. AEC-Q100 not applicable as this is a standard EEPROM, not an automotive-grade part.
