AT25DL081-SSHN-B

Product Overview

The AT25DL081-SSHN-B from Renesas Electronics Corporation is an 8-Mbit non-volatile FLASH memory IC with an SPI serial interface. It is housed in an 8-SOIC surface-mount package and is suitable for embedded systems that require serially accessed code, configuration, or data storage. The device operates from a 1.65 V to 1.95 V supply and supports a clock frequency of 100 MHz. Its memory organization is 256 bytes x 4096 pages.

Key Features

• 8-Mbit FLASH memory organization of 256 bytes x 4096 pages
• SPI serial interface with a 100 MHz clock frequency
• Write cycle times of 8 µs for word operations and 3 ms for page operations
• 1.65 V to 1.95 V supply voltage range
• Operating temperature range of -40°C to +85°C (TC)
• 8-SOIC (0.154 in, 3.90 mm width) surface-mount package
• Non-volatile memory format using FLASH technology

Applications

• Firmware or code storage for SPI-attached host systems
• Configuration and parameter retention for embedded controllers
• Lookup-table or calibration data storage for SPI-connected processors
• Small-record data logging in non-volatile memory for embedded devices

Design & Procurement Notes

Design teams should confirm that the host controller supports SPI operation at a 100 MHz clock and that the system supply remains within 1.65 V to 1.95 V. The 256-byte page organization is relevant for buffer sizing and page write operations, while the 8 µs word and 3 ms page write times should be considered in firmware update or data logging routines. The 8-SOIC footprint, including the 0.154 in and 3.90 mm width, should be checked against the PCB layout and surface-mount assembly process. The -40°C to +85°C (TC) operating range should be verified for the intended environmental conditions.
