AT25SF081B-SHD-T 詳細描述
Product Overview
The AT25SF081B-SHD-T from Renesas Electronics Corporation is a non-volatile FLASH memory IC using NOR technology. It provides 8Mbit of storage organized as 1M x 8 and communicates through an SPI Quad I/O interface at a clock frequency of 108 MHz. 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 is supplied in a surface-mount 8-SOIC package with a 5.30mm body width.
Key Features
- 8Mbit non-volatile FLASH memory using NOR technology, organized as 1M x 8.
- SPI Quad I/O interface with a 108 MHz clock frequency.
- Word write cycle time of 50µs and page write cycle time of 2.4ms.
- 2.5V to 3.6V supply voltage range.
- Operating temperature range of -40°C to 85°C (TC).
- Surface-mount 8-SOIC package with 0.209 in (5.30 mm) width.
Applications
- Storing firmware images in embedded systems that use SPI memory.
- Retaining configuration settings or calibration values after power cycling.
- Providing local non-volatile data storage in compact surface-mount assemblies.
Design & Procurement Notes
Designers should verify that the host controller supports SPI Quad I/O signaling and a 108 MHz clock before selecting the AT25SF081B-SHD-T. The 2.5V to 3.6V supply range and -40°C to 85°C (TC) operating range should be checked against the system power rail and board temperature conditions. The 1M x 8 organization can simplify byte-oriented addressing for 8Mbit of capacity, while the 50µs word and 2.4ms page write times may influence firmware update or data logging scheduling. The 8-SOIC surface-mount package with 0.209 in (5.30 mm) width should be confirmed against the board layout and assembly constraints.
