Visão Geral

Description

25LC160AT-I/SN is Microchip’s 16‑Kbit I2C serial EEPROM (2,048 x 8). It stores nonvolatile data for microcontrollers and uses a two‑wire I2C interface up to 400 kHz. Packaged in an 8‑pin SOIC (SN) with industrial temperature range (-40°C to +85°C); A0–A2 address pins allow multiple devices on a bus, and WP provides write protection. Supply voltage is 2.7–5.5 V. Features include standard and fast I2C modes, random and sequential reads, and 16‑byte page writes. Typical write cycle time is 5 ms (max around 10 ms). Endurance is about 1,000,000 write cycles with data retention around 100 years. Suitable for config storage, calibration data, logs, and other small I2C memory needs in embedded systems.

Equivalent

Equivalent SPI 16K serial EEPROMs (pin/protocol compatible):
- AT25C160 (Atmel/Microchip)
- CAT25C16 (Catalyst Semiconductor)
- 25LC160A / 25AA160A (Microchip)
Notes: All are 16K SPI EEPROMs in 8-pin packages. Check voltage range (2.7–5.5V), timing, and WP/HOLD pin usage to ensure full compatibility.

Features

Pinout

Pin count: 8 (8-pin package, e.g., SOIC8/DIP8).
Function: 16K-bit SPI Serial EEPROM. Pins:
- 1 CS – Chip Select (active low)
- 2 SO – Serial Data Out
- 3 WP – Write Protect
- 4 VSS/GND – Ground
- 5 SI – Serial Data In
- 6 SCK – Serial Clock
- 7 HOLD – Hold
- 8 VCC – Power
Notes: Non-volatile memory; uses SPI interface with CS, SCK, SI, SO, plus WP and HOLD for protection and hold functionality.
