AT25SF041B-SSHD-B 詳細描述
Product Overview
The AT25SF041B-SSHD-B from Renesas Electronics Corporation is a non-volatile NOR flash memory IC with a 4Mbit capacity organized as 512K x 8. It uses an SPI Quad I/O interface and supports a clock frequency of 108 MHz for serial memory access in embedded hardware. The device operates from a 2.5V to 3.6V supply and is specified for an operating temperature range of -40°C to 85°C (TC). It uses an 8-SOIC surface-mount package with 0.154 inch (3.90mm) width.
Key Features
- 4Mbit non-volatile NOR flash memory organized as 512K x 8
- SPI Quad I/O interface with 108 MHz clock frequency
- 2.5V to 3.6V supply voltage range
- Operating temperature range of -40°C to 85°C (TC)
- Write cycle time of 5µs for word and 2.5ms for page
- 8-SOIC surface-mount package, 0.154 inch (3.90mm) width
Applications
- Embedded firmware and code storage in microcontroller-based systems
- Non-volatile configuration data retention for system setup
- Calibration data storage for measurement and adjustment
- Serial data buffering for host processor systems
Design & Procurement Notes
Designers should confirm host controller compatibility with the SPI Quad I/O interface, the 108 MHz clock frequency, and the 5µs for word and 2.5ms for page write cycle timing. The 2.5V to 3.6V supply range should be matched to the board power rail, and the -40°C to 85°C (TC) operating temperature range should be considered for the intended environment. Host firmware should also account for the 512K x 8 memory organization when planning address mapping. The 8-SOIC surface-mount package requires a footprint compatible with 0.154 inch (3.90mm) width leads.
