Features

  • Dual-SPI interface for 2x data throughput compared to standard SPI
  • Two 256-byte SRAM buffers for read-modify-write operations
  • Flexible page erase with individual page, block, or sector granularity
  • Page program with built-in erase cycle (simplifies write operations)
  • Deep power-down mode with 7μA typical current
  • Hardware and software write protection

Applications

  • Data logging and event recording in industrial systems
  • Firmware and code storage for embedded processors
  • Audio and voice storage in consumer devices
  • Parameter and calibration data storage
  • Secure data storage with write protection

The AT45DB081E-SSHN-T from Microchip Technology is an 8Mbit (1 megabyte) DataFlash serial Flash memory optimized for data logging, firmware storage, and general-purpose non-volatile storage applications. Unlike standard SPI Flash memories, the DataFlash architecture integrates two 256-byte SRAM buffers that enable read-modify-write operations without external RAM, simplifying data logging applications. The device supports standard SPI (up to 85MHz) and Dual-SPI (2-bit) interfaces for high-throughput data transfer, with flexible page erase granularity including individual page (256 bytes), block (2KB), sector (64KB), and full-chip erase options.

The AT45DB081E operates using a unique buffer-based DataFlash architecture. (1) The SPI interface receives commands, addresses, and data through the SI pin (and optionally SO pin in Dual-SPI mode) synchronized to the SCK clock, with CS active-low chip select. (2) The two 256-byte SRAM buffers (Buffer 1 and Buffer 2) serve as intermediate storage for Flash page operations. A Main Memory Page Program via Buffer operation loads data into a buffer and then transfers it to the Flash array in a single command sequence, performing the erase and program cycle automatically. (3) The Flash array is organized as 4096 pages of 256 bytes each, with pages further grouped into blocks (8 pages) and sectors (256 pages). Read operations can access the Flash array directly or through either buffer, with continuous read capability across page boundaries.

Pin Name Function
1 SI SPI data input (MOSI)
2 SO SPI data output (MISO) / Dual-SPI I/O1
3 WP Hardware write protect (active low)
4 VSS Ground
5 SI/SIO0 SPI input / Dual-SPI I/O0
6 SCK SPI clock
7 RESET Hardware reset (active low)
8 VCC Power supply (2.3-3.6V)
  • Industrial data logging with continuous write using dual-buffer ping-pong operation
  • Firmware and boot code storage with Dual-SPI high-speed read access
  • Audio and voice recording applications with sequential page storage
  • Parameter and calibration storage with flexible write protection
  • Medical device event recording with SRAM buffer for atomic writes
