Übersicht

Description

AT45DB081E-SSHN2B-T is an 8‑Mbit Serial DataFlash memory from Atmel (now Microchip) in an SSHN2B‑T 8‑pin package. It provides nonvolatile storage with an SPI-compatible interface and is intended for embedded data storage, firmware buffering, or configuration data.
Key points:
- SPI interface (CS, SCK, SI, SO) with a standard command set
- Main memory array plus two internal data buffers for fast writes
- Supports reads (including continuous/high‑speed reads), page programming, and sector/block erases
- Features include Ready/Busy status, hardware write protection, and Deep Power‑Down for low power
- Operating voltage typically in the 2.7–3.6V range (voltage depends on revision)
- Package: SSHN2B‑T, an compact 8‑pin package
Typical uses: firmware storage, data logging, buffering data for MCUs, and general nonvolatile storage in space‑constrained systems.
For exact timing, page size, memory organization, and command codes, refer to the AT45DB081E datasheet.

Features

Here are concise features of AT45DB081E-SSHN2B-T:
- 8 Mbit (1 MB) serial DataFlash memory with SPI-compatible interface
- Operating voltage 2.7–3.6 V; industrial temperature range -40°C to +85°C
- 264-byte page size; memory organized in pages
- Two internal 264-byte SRAM buffers for fast data transfer (Buffer A/B)
- Page programming via buffers (Buffer to Memory Page Program)
- Read operations: random access, Page Read and Continuous/Sequential Read
- Erase options: Sector erase (4 KB), Block erase (32 KB and 64 KB), Chip erase
- Ready/Busy status (RDY/BSY); hardware write-protect (WP) pin
- Low-power modes: Deep Power-Down and standby
- SPI clock up to high speed (typical implementations up to tens of MHz)
- 8-pin package variant (SSHN2B-T)
These cover core functionality and typical operating conditions.
