Design Notes

Place pull-up resistors (typically 4.7 kOhm) on the SCL and SDA lines. The pull-up resistors should be connected to the same supply voltage as the EEPROM (VCC). For high-speed I2C (400 kHz), keep the bus capacitance below 400 pF. Place the pull-up resistors close to the EEPROM to minimize trace length and reduce noise.

Ensure the write protect (WC) pin is properly connected. If left floating, it may cause unpredictable write protection. Tie WC to ground for normal operation or to VCC for write protection. Also, respect the write cycle time (5 ms) after each write command; initiating a write before the cycle completes can corrupt data.

Decouple the VCC pin with a 0.1 uF ceramic capacitor placed as close to the pin as possible. This helps filter noise and ensures stable operation. The M24C01-RMN6TP has a standby current of 1 uA, but during write operations, current spikes can occur; the decoupling capacitor helps absorb these transients.
