AT25SF081B-SSHD-T FLASH - NOR Memory IC 8Mbit SPI - Quad I/O 108 MHz
The AT25SF081B-SSHD-T is Renesas (Dialog) 8Mbit serial NOR flash memory in an 8-pin SOIC surface mount package, supporting standard SPI, dual I/O and quad I/O communication up to 108MHz clock speed. It operates with 2.5V to 3.6V single supply voltage, features XiP execute-in-place function, SFDP parameter support and uniform 4KB sector erase architecture. This non-volatile flash delivers 100,000 program/erase cycles and 20-year data retention, works within -40°C to 85°C industrial temperature range, and integrates OTP security registers plus hardware and software write protection for reliable firmware and configuration storage in embedded IoT and consumer electronic systems.
Key Features and Applications
● Multi-mode SPI interface supporting single, dual and quad I/O, maximum 108MHz frequency and XiP continuous read for direct code execution.
● Wide 2.5V~3.6V operating voltage, compatible with common 3.3V embedded platforms and featuring low standby power consumption.
● Flexible erase options including 4KB sector, 32KB block, 64KB block and full chip erase, with 256-byte page programming buffer.
● Hardware WP pin, software block protection and three OTP security registers with factory pre-programmed unique 64-bit ID for data security.
● Program and erase suspend/resume function allows high-priority read operations during ongoing flash erasure.
This serial NOR flash is widely adopted for MCU and FPGA bootloader and firmware storage, IoT wireless sensor nodes, smart home devices, portable handheld instruments, networking peripheral modules, consumer audio equipment and industrial embedded control boards. It stores boot codes, calibration parameters, unique device identifiers and system log data for compact embedded hardware requiring reliable nonvolatile memory.
