Descripción general

Description

W25X40BVSSIG is a Winbond 4-Mbit serial SPI Flash memory in an 8‑pin SSIG (SOP‑8) package. It is designed to store firmware or data for microcontrollers and embedded systems.
Key points:
- Capacity: 4 Mbit (512 KB).
- Interface: Serial SPI with standard and fast read; supports dual/quad I/O read modes on some variants.
- Voltage: 2.7–3.6 V operation.
- Performance: Read up to high speeds (typically up to ~104 MHz); page program up to 256 bytes; sectors (often 4 KB) and blocks (32 KB/64 KB) erase; chip erase option.
- Commands: Typical SPI flash set includes WREN/WRDI, RDSR/WRSR, READ/FAST READ, PP (page program), sector/block/chip erase, and status/config registers.
- Power: Low active current; deep power-down mode available.
- Endurance/retention: ~100,000 write/erase cycles per sector; data retention around 10–20 years.
- Applications: BIOS/firmware storage, bootloaders, embedded data logging.
Note: Always refer to the exact Winbond datasheet for precise timing, command set, and feature details for your package/SR variant.

Features

- Capacity: 4 Mbit (512 KB) serial Flash memory.
- Interface: SPI-compatible serial interface (standard SPI; 3-byte addressing).
- Voltage and temp: 2.7–3.6 V supply; operating temp typically -40°C to 85°C.
- Page/erase: 256-byte page programming; 4 KB sector erase; 32 KB/64 KB block erase; chip erase supported.
- Speed: Fast read up to 80 MHz (serial clock); standard read lower.
- Status/Protection: Write Enable Latch (WEL), Write-In-Progress (WIP) status; status register with block/write protection features.
- Power: Deep power-down mode for low power; normal and low-power operation modes.
- Endurance/Retention: Endurance typically ≥100,000 erase cycles; data retention around 20 years.
- Packaging: 8-pin package (SSIG/SOIC8 form factor).
- Applications: Suitable for code and data storage in microcontrollers and embedded systems.

Package

8-pin SOP (SOP-8) package; leaded, RoHS‑compliant. The SSIG suffix denotes the SOP‑8 package variant.

Pinout

- Pin count: 8 pins (SOIC-8 package).
- Function: 4 Mbit serial NOR flash memory with SPI interface. Uses CS, CLK, DI (MOSI), DO (MISO) plus WP# (write protect), HOLD#, VCC, and GND for operation.

Manufacturer

- Manufacturer: Winbond Electronics Corporation.
- What kind of company: A Taiwan-based semiconductor company that designs and manufactures memory ICs (NOR/NAND Flash, DRAM) for consumer, automotive, and industrial applications, operating as a global memory solutions provider.

Application

Applications of W25X40BVSSIG (4 Mbit serial flash):
