Description
AT25SF161B-SHB-T is a 16-Mbit serial flash memory from Atmel/Microchip with an SPI interface. It is designed for code and data storage in embedded systems and uses 3-byte addressing, allowing access to a 2-MB array from a single device.
Key points:
- Interface: SPI (SCK, MOSI, MISO, CS)
- Density: 16 Mb
- Voltage: typically 2.7–3.6 V
- Features: fast read, page program, sector/block erase, write enable/disable, status register and protection features, low-power modes (including deep power-down)
- Package: SHB denotes the 8-pin surface-mount package variant; -T indicates tape-and-reel packaging for production
- Typical uses: boot firmware, firmware/data storage for MCUs, data logging, secure memory in consumer/industrial electronics
Why choose: small footprint, simple software interface, robust SPI memory with standard erase/program operations and low idle power.
