4 Mbit SPI NOR flash for embedded code and data logging
The Microchip AT45DB041E-SHNHA-T is a 4 Mbit serial NOR flash memory organized as 264 bytes per page across 2048 pages. It communicates over an SPI bus at up to 85 MHz. The supply range is 1.65 V to 3.6 V. Page write completes in 8 µs and a full page erase in 3 ms.
Package and temperature grade — board fit and environment
Housed in an 8-SOIC wide-body package (5.30 mm width), the AT45DB041E-SHNHA-T uses a standard footprint that routes easily on two-layer boards and is hand-solderable for prototyping. The industrial temperature range of -40°C to 85°C covers outdoor telecom cabinets, factory-floor controllers, and unheated enclosures — but not under-hood automotive or extended military soak.
Lifecycle and supply posture
This part carries an Active product status with ROHS3 compliance.
