Заметки по проектированию
Place a 0.1uF decoupling capacitor close to the VCC pin (pin 8) and a 10kOhm pull-up resistor on both SDA and SCL lines to VCC. For high-speed operation (1 MHz), keep the I2C trace lengths short and avoid stubs to minimize signal reflections.
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 to enable write protection. Also, verify that the device address pins (A0, A1, A2) are set correctly to avoid bus conflicts.
The M24C512-RMN6TP operates from 1.8V to 5.5V. Ensure the supply voltage is stable and within this range. During write operations, the current can spike; use a bulk capacitor (e.g., 10uF) in addition to the 0.1uF decoupling capacitor to maintain voltage stability.
