概要

Description

SST25WF080B-40I/SN is an 8-megabit (1 MB) serial SPI flash memory from Silicon Storage Technology (SST; now Microchip). It’s designed for firmware and data storage in embedded systems.
Key features
- Capacity: 8 Mbit; 3-byte addressing (24-bit) for 1,048,576 bytes.
- Interface: 4-wire SPI; supports standard SPI modes (clock up to 40 MHz).
- Voltage: typically 2.7–3.6 V (single-supply).
- Page/Erase: 256-byte pages; 4 KB sectors; 32 KB and 64 KB blocks.
- Commands: WREN, WRDI, READ (03h), FAST READ (0Bh), PAGE PROGRAM (02h), sector/block erase, READ STATUS (05h), READ ID (90h/ABh), etc.
- Special modes: Deep Power-Down (B9h) and release (ABh); WP#/HOLD pins for protection and hold.
- Temp range and package: Industrial temperature (-40 to +85°C); 8-pin small-outline package (SN suffix indicates RoHS-compliant).
Applications
- Firmware boot/loading, code storage, data logging in microcontroller systems.
Note: exact electrical specs and command timing should be confirmed from the latest datasheet for -40I/SN.

Package

It comes in an 8‑pin SOP (SOIC) package (150‑mil body), RoHS‑compliant.

Pinout

- Pin count: 8 pins (8-pin package such as SOIC/SOP)
- Function: 8 Mbit SPI serial flash memory. Pinout: 1 CS, 2 DO (MISO), 3 WP#, 4 GND, 5 DI (MOSI), 6 CLK, 7 HOLD#, 8 VCC.

Manufacturer

- Manufacturer: SST (Silicon Storage Technology), a semiconductor company that designs and manufactures non-volatile memory products (notably serial flash memory). SST is now a brand of Microchip Technology, a leading global semiconductor company.

Application

Applications: External 8-Mbit SPI flash for embedded systems needing reliable firmware storage and data storage.
- Firmware storage and bootloaders for MCUs
- Firmware updates and recovery in IoT, automotive, and industrial devices
- Data logging and temporary storage for sensors
- Small-file storage/cache for consumer electronics, wearables, and IoT
- Code caching/expansion memory in MCU-based designs
Key specs: 40 MHz SPI, industrial temp range (-40°C to +85°C), 8 Mbit.
