概述

Description

W25Q128JVEJQ is a Winbond 128-Mbit serial Flash memory with an SPI interface. It’s widely used to store firmware, code, and data in embedded systems.
Key points:
- Capacity: 128 Mbit (16 MB)
- Interface: SPI (standard), with dual/quad I/O read modes for higher throughput
- Organization: 256-byte pages; 4 KB sectors; 32 KB/64 KB blocks; total 16 MB usable space
- Voltage: typically 2.7–3.6 V
- Features: Read and Fast Read; Page Program (256 bytes); Sector Erase (4 KB); Block Erase (32 KB/64 KB); Chip Erase; Write Enable Latch; status register with WIP/WEL; protection/security features
- Package: commonly 8-pin SOIC/SOP
- Temperature: available in standard and industrial ranges (often -40°C to +85°C)
- Applications: firmware/boot memory, configuration data, and other persistent storage in microcontroller-based designs
This part is chosen for compact pin count, decent endurance, and broad MCU support.

Features

W25Q128JVEJQ is a Winbond 128-Mbit Serial NOR Flash. Key features:
- Capacity: 128 Mbit (16 MB)
- Voltage: 2.7–3.6 V (3.3 V nominal)
- Interface: SPI with Standard, Dual I/O, and Quad I/O (DQ) modes; up to 104 MHz
- Read/Access: Fast read; dual/quad read options
- Programming: Page program up to 256 bytes
- Erase: 4 KB sectors; 32 KB blocks; 64 KB blocks; Chip erase
- Endurance/Retention: ~100,000 P/E cycles; 20-year data retention
- Power: Deep power-down mode; low standby current
- Security: Block protection, write-protect, protection registers
- Addressing: 3-byte addressing by default; 4-byte addressing mode available for larger maps
- Temperature: Industrial range typically -40°C to 85°C
- Package: 8-pin SOP/SOIC (and other small packages)
Ideal for code storage, boot ROMs, and firmware updates in embedded systems.

Package

8-pin SOP (SOIC-8) surface-mount package.

Pinout

- Pin count: 8 pins (SOP-8/8-pin package)
- Function: Winbond W25Q128JVEJQ is a 128-Mbit serial flash memory with SPI interface (CS, CLK, DI, DO) plus WP and HOLD, for non-volatile storage of firmware/data. Typical operations include read/fast read, page program, sector/block erase, and chip erase.

Manufacturer

Manufacturer: Winbond Electronics Corporation.
What kind of company: A Taiwanese semiconductor company that designs and manufactures memory ICs (notably NOR flash and DRAM) for consumer electronics, automotive, and embedded applications.

Application

- Firmware storage and boot memory for microcontrollers and embedded systems
- Code and data storage for consumer electronics (set-top boxes, cameras, multimedia players, USB devices)
- IoT and industrial devices (sensors, gateways, dashboards) for firmware, logs, and config
- Networking and storage peripherals (routers, modems, NAS, USB interfaces)
- Automotive ECUs and infotainment where external flash stores firmware/data

Equivalent

W25Q128JVEJQ is a 128 Mbit, 3.3 V SPI flash. Common equivalents from other vendors (density, voltage, SPI):
- Gigadevice GD25Q128C
- Macronix MX25L12845G or MX25L12835F
