Sobre este producto
- AT24C02 EEPROM Module - 2Kbit I²C Interface Storage capacity: 2Kbit (256 × 8 bits, supports page read/write) Interface: I²C bus (compatible with standard/fast/high-speed mode, up to 400kHz) Voltage: 1.8V ~ 5.5V DC (wide voltage compatible with 3.3V/5V systems) Data retention: ≥100 years @ 25°C Erase life: ≥1,000,000 cycles/byte Temp range: -40°C ~ +85°C ( Reliable) Package: SOIC-8 (surface mount, PCB compatible) Address pins: A0-A2 (supports 8 devices, addresses 0x50~0x57) Main function: Non-volatile memory with I²C interface, supports single-byte/page write (8 bytes/page), random read, and built-in write protection (WP pin). Low power (standby <1µA), Suitable for for Arduino /STM32 projects. Pin functions: VCC: 1.8V ~ 5.5V DC (0.1µF ceramic capacitor required) GND: Shared with main system ground SDA: I²C data line (4.7kΩ pull-up to VCC) SCL: I²C clock line (4.7kΩ pull-up to VCC) A0/A1/A2: Address selection (default 0x50) WP: Write protect (high = lock, low = enable) FAQ: Q1: No I²C response? A1: Check SDA/SCL pull-ups, address match, and I²C master enable. Q2: Read error after writing? A2: Wait 5ms after write, ensure page ≤8 bytes. Q3: How to set multiple device addresses? A3: Use A0/A1/A2 combinations (0x50~0x57). Q4: Is WP floating safe? A4: No, must be grounded or connected to VCC.
