AT25SF041B-SHD-T 詳細描述
Product Overview
The AT25SF041B-SHD-T from Renesas Electronics Corporation is a non-volatile NOR flash memory IC providing 4 Mbit of storage in an 8-SOIC surface-mount package. The FLASH - NOR technology and 512K x 8 organization define its memory format and address structure. The device communicates through an SPI - Quad I/O interface at a clock frequency of 108 MHz. It operates from a 2.5V to 3.6V supply and is specified for an operating temperature range of -40°C to 85°C (TC). Word and page write cycle times are 50 µs and 2.4 ms, respectively.
Key Features
- 4 Mbit non-volatile NOR flash memory with 512K x 8 organization
- SPI - Quad I/O serial memory interface supporting a 108 MHz clock
- 2.5V to 3.6V supply voltage range
- 50 µs word write cycle time and 2.4 ms page write cycle time
- -40°C to 85°C (TC) operating temperature range
- 8-SOIC (0.209 in, 5.30 mm width) surface-mount package
Applications
- Embedded firmware storage in systems with serial memory interfaces
- Configuration and calibration data retention in equipment requiring non-volatile storage
- Parameter logging in control systems
Design & Procurement Notes
Design considerations include matching the 2.5V to 3.6V supply domain, routing the SPI - Quad I/O signals for operation at 108 MHz, and confirming that the 50 µs word and 2.4 ms page write cycle times suit the update routine. The 8-SOIC (0.209 in, 5.30 mm width) package and -40°C to 85°C (TC) range should be checked against the board layout and thermal environment. The 4 Mbit capacity and 512K x 8 organization determine address mapping, data partitioning, and data layout.
