Description

AT24C32CN-SH-T is a 32‑Kbit I2C serial EEPROM from Atmel/Microchip. It stores 4 KBytes of non-volatile data and is accessed over the I2C two‑wire bus.
Key features
- Capacity: 32 Kbit (4096 x 8).
- Interface: I2C with two‑byte (16‑bit) memory addressing (0x0000–0x0FFF).
- Addressing: A0–A2 pins select up to 8 devices on the same bus; WP pin for write protection.
- Page size: 32 bytes; supports random and sequential reads/writes.
- Write cycle: Typical tWC ~5 ms; endurance around 1,000,000 write cycles.
- Voltage: Wide supply range (check exact grade; commonly ~1.7–5.5 V).
- Temperature: Available grades for industrial/extended ranges; typical operation −40 to 85°C (and higher for some versions).
- Package: 8‑pin small‑outline; -SH‑T suffix indicates a specific small-outline package in tape-and-reel.
Typical use cases
- Persisting configuration data, calibration tables, small data logs, or device IDs for microcontroller projects.
Pinout (8 pins): A0, A1, A2, GND, SDA, SCL, WP, VCC.
