概要

Description

AT45DB161E-MHD-T is a 16‑Mbit Serial DataFlash memory from Atmel/Microchip. It provides non-volatile storage for embedded systems and is accessed over a Serial Peripheral Interface (SPI).
Key points
- SPI-compatible interface with commands for read, write, erase, and status.
- Two internal data buffers plus page-level programming and sector/block erase.
- Random read capability with 3-byte addressing; supports fast/continuous read modes.
- Features such as a status register (busy flag), deep power-down, and hardware write protection.
- RoHS-compliant, typically available in an 8-pin MHD-T package (package and reel details vary by supplier).
Typical use
- Store firmware, configuration, logs, or data for microcontroller systems.
- Efficient data updates by buffering data in internal buffers and then writing to flash (BUFFER WRITE followed by BUFFER-TO-PAGE).
Note
- Check the datasheet for exact page sizes, erase block sizes, timing, and the specific packaging/temperature details for your lot.

Features

Here are the key features of AT45DB161E-MHD-T (16‑Mbit Serial DataFlash):
- 16 Mbit (2 MBytes) serial DataFlash with SPI interface
- SPI-compatible interface with CS, SCK, SI, SO; supports standard and continuous read
- Page-based memory with two internal data buffers for buffered writes
- Flexible erase: page erase, block/sector erase, and chip erase
- Read/Write operations with Ready/Busy status; fast programming via internal buffers
- Endurance and retention: typical ~100k P/E cycles; data retention ~20 years
- Low‑power modes including Deep Power-Down
- Supply voltage: typically 2.7–3.6 V
- Operating temperature: industrial range (typical -40°C to +85°C)
- Packaging: compact 8‑pin package; MHD‑T denotes available tape-and-reel/packaging variant
Note: exact page size, block sizes, and timings are specified in the datasheet for the device revision.

Package

8-pin Small Outline Integrated Circuit (SOIC) package, Tape‑and‑Reel (T).

Pinout

- Pin count: 8 pins.
- Function: 16-Mbit Serial DataFlash memory (SPI interface). It provides non-volatile storage with an SPI-compatible interface (CS, SCK, SI, SO) plus WP and HOLD, plus VCC and GND.

Manufacturer

Manufacturer: Atmel Corporation (now part of Microchip Technology). Type of company: A semiconductor company that designs and manufactures integrated circuits, including memory devices (DataFlash) and microcontrollers.

Application

Applications of AT45DB161E-MHD-T (16‑Mbit SPI DataFlash):
- Embedded systems: firmware storage, bootloaders, and configuration data
- Data logging: industrial, environmental, medical sensors (event logs, history)
- Caching/buffering: high‑speed data streams (audio, video capture, image sensors)
- Consumer electronics: cameras, MP3 players, handheld devices
