Key Differentiators
- Wide operating voltage range (1.8V to 5.5V) (vs M24C08-WMN6TP)
- Industrial temperature range (-40C to +85C) (vs AT24C08C-SSHM-T)
- Pin-compatible with industry-standard SOIC-8 EEPROMs (vs CAT24C08LI-G)
Design Notes
Place a 0.1 uF ceramic decoupling capacitor as close as possible to the VCC pin (pin 8) and GND (pin 4) to filter high-frequency noise. For I2C lines, use pull-up resistors (typically 4.7 kOhm) to VCC. The pull-up values may need adjustment based on bus capacitance and speed. Ensure the SDA and SCL traces are kept short and away from high-noise sources.
Do not leave the WC (write protect) pin floating; tie it to GND for normal write operations or to VCC to protect the memory. Ensure the device address pins (A0, A1, A2) are connected to defined logic levels (GND or VCC) to avoid address conflicts on the I2C bus. Also, verify that the I2C bus speed does not exceed 400 kHz to ensure reliable communication.
The M24C08-RMN6TP has a maximum active current of 2 mA at 400 kHz. During write operations, the current may spike; ensure the power supply can handle transient loads. The standby current is only 1 uA, making it suitable for battery-powered applications. Use a low-dropout regulator if the supply voltage is near the minimum operating voltage to maintain stable operation.
Compliance Information
