AT25FF081A-SSHN-B

Product Overview

The AT25FF081A-SSHN-B from Renesas Electronics Corporation is a non-volatile FLASH memory IC using NOR technology with an 8Mbit capacity and a 2M x 4 organization. It is packaged in an 8-SOIC surface-mount package and communicates through an SPI - Quad I/O interface at a 133 MHz clock frequency. The device operates from a 1.65V to 3.6V supply and is specified for an operating temperature range of -40°C to 85°C (TC).

Key Features

• 8Mbit non-volatile FLASH memory with NOR technology and 2M x 4 organization.
• SPI - Quad I/O serial interface supporting a 133 MHz clock frequency.
• Write cycle times of 32µs for word writes and 6.5ms for page writes.
• 1.65V to 3.6V supply voltage range.
• 8-SOIC surface-mount package with 0.154" (3.90mm) width.
• Operating temperature range of -40°C to 85°C (TC).

Applications

• Embedded systems that store program code or configuration data in serial NOR flash.
• Control boards that retain calibration, identity, or parameter data across power cycles.
• Microcontroller or processor systems that use an SPI flash interface for external code or data storage.

Design & Procurement Notes

When selecting this device, verify that the host controller supports an SPI - Quad I/O serial flash interface and can operate within the 133 MHz clock frequency specification. Confirm that the board supply remains within 1.65V to 3.6V during normal operation and that the operating temperature stays within -40°C to 85°C (TC). Account for the 32µs word write and 6.5ms page write timing in firmware or system write sequences, and check that the 8-SOIC (0.154", 3.90mm) footprint and surface-mount assembly process match the PCB design.
