Memory IC datasheet and documents for AT25DF081-SSHN-B
Memory IC Overview
The AT25DF081-SSHN-B is an 8-megabit SPI serial flash memory device manufactured by Renesas Electronics. It operates with a minimum supply voltage of 1.65V and supports clock frequencies up to 66 MHz. The component utilizes a single, dual SPI interface for data transfer. It is housed in an 8-pin SOIC-N package with a 150mil body width. The device is rated for industrial temperature ranges from -40°C to +85°C.
Memory IC Feature Summary
- Supports low-voltage operation starting at 1.65V
- Compatible with standard SPI protocols including dual I/O modes
- Designed for high-volume consumer applications requiring code storage
Memory IC Applications
- Consumer electronics firmware storage
- Embedded system program code retention
- Data logging in portable devices
Memory IC Procurement Notes
Verify the specific suffix 'B' indicates tube packaging rather than tape and reel. Confirm the 1.65V minimum voltage rating against your system power rails. Ensure the 66 MHz speed grade meets your timing requirements. Check current availability status as this series may have restricted supply or lifecycle limitations.
Memory IC Selection Notes
Select this part when a low-voltage 8Mbit capacity is required. Compare against the AT25DF081A series if higher speeds or different voltage ranges are needed. Ensure the SOIC-N 8-pin footprint matches your PCB layout. Verify compatibility with your microcontroller's SPI controller capabilities.
Memory IC Part Context
This component belongs to the AT25DF081 family of serial flash memories. It serves as a non-volatile storage solution for embedded systems. The device replaces older parallel flash technologies in space-constrained designs. It maintains backward compatibility with standard SPI command sets.
Memory IC Replacement Considerations
The AT25DF081A-SSH-B offers similar capacity but operates at 2.7V minimum and supports 100 MHz speeds. The AT25DF081A-SSH-T shares the 3.0V range but uses tape and reel packaging. Verify pinout and command set compatibility before substitution.
