Description
Introduction to AT24C32CN-SH-T
- Type: 32‑Kbit I2C Serial EEPROM (4,096 x 8), used for nonvolatile storage.
- Interface: I2C two‑wire, up to 400 kHz (Fast Mode); device address base 0x50 with A0–A2 selecting the subaddress.
- Memory addressing: 16‑bit word addressing (two‑byte memory address) to access locations.
- Power and temp: Vcc 2.7–5.5 V; temperature range typically -40°C to +85°C (industrial).
- Endurance/retention: about 1,000,000 write cycles; data retention roughly 100 years.
- Package: 8‑pin device; SH suffix indicates a small‑outline package; -T denotes Tape & Reel packaging.
- Applications: config data, device IDs, calibration data, small data logging in microcontroller systems.
- Key note: Suitable when you need extra nonvolatile storage with simple I2C interface and moderate density without SRAM refresh requirements.
