概述

Description

The 25LC160AT-I/SN is a 16-kbit serial EEPROM with an SPI interface. It stores 2K x 8 data non-volatile memory that retains data when power is removed. Interface pins: CS, SCK, SI (MOSI), SO (MISO); plus WP (write protect) and HOLD. It operates from a single supply (roughly 2.7–5.5 V). Features include random/read, page-write capability, write enable/disable control, and a status register with a write-in-progress bit. Useful for storing small config data, calibration data, or logs in embedded systems. Packaging is 8-pin (e.g., SOIC/DIP), and the suffix -I typically indicates industrial temperature range, while -SN denotes RoHS-compliant packaging. For exact timing, page size, and command set, refer to the datasheet.

Features

Here are the key features of 25LC160AT-I/SN (8-pin SPI EEPROM):
- 16 Kbit serial EEPROM (2K × 8)
- SPI-compatible interface (CS, SCK, SI, SO)
- Operating voltage: 2.7–5.5 V
- Industrial-temp variant: -40°C to +85°C (suffix -I)
- 2K × 8 organization; supports random and sequential reads
- Page write capability (16-byte page); single-write operation with address increment
- Write Enable (WREN)/Write Disable (WRDI) and Write Protect (WP) input
- HOLD input to pause SPI communications (low-power feature)
- Endurance: typically up to 1,000,000 write cycles
- Data retention: typically 100 years
- 8-pin package (SOIC/8), RoHS compliant
- Typical SPI clock up to ~20 MHz (device supports standard SPI modes)
Note: exact timing, power, and clock specs may vary by exact package/revision; consult the datasheet for precise numbers.

Package

8-pin Small Outline Integrated Circuit (SOIC) surface-mount package (SMD).

Pinout

- Pin count: 8 pins (8-pin package)
- Function: 16K-bit serial SPI EEPROM (Microchip 25LC160A); non-volatile memory with SPI interface. Pin roles typical: 1 CS, 2 SO, 3 WP, 4 GND, 5 SI, 6 SCK, 7 HOLD, 8 VCC. Used for read/write storage with write-protect and hold controls.

Manufacturer
