M24C32-WDW6TP

M24C32-WDW6TP is a 32‑kbit I2C (2‑wire) Serial EEPROM from STMicroelectronics (M24Cxx family). It provides non-volatile storage for microcontroller applications.
Key points:
- Capacity: 32 Kbit (4 KBytes) of writable memory.
- Interface: I2C two‑wire bus; supports standard and fast modes.
- Memory organization: 4096 x 8 bits.
- Read/Write: random read, sequential read; page write up to a device‑specific page size (typical ~32 bytes); write cycle around a few milliseconds.
- Endurance/Retention: ~1,000,000 write cycles per byte; data retention on the order of 100 years.
- Addressing: uses I2C device address with A0–A2 pins; supports multiple devices on the same bus; internal memory addressing uses a small address pointer (memory address within the device).
- Power: operates from a low to mid voltage range (check datasheet; commonly ~1.7–5.5 V); includes a low‑power mode.
- Package: 8‑pin package; WDW6TP indicates specific packaging/ordering variant (tape‑and‑reel, temperature range). Refer to the datasheet for exact specs.
Ideal for small, non‑volatile data storage in embedded systems. For exact electrical details and pinout, consult the official datasheet.
