概述

Description

GD25B256EFIRR is a 256-Mbit serial NOR flash memory from GigaDevice. It stores firmware or data and is accessed via an SPI-compatible interface (standard SPI, with optional dual/quad I/O modes on some variants). Key points:
- Capacity: 256 Mbit (32 MB)
- Interface: SPI-compatible; supports standard and fast read; some modes may include dual/quad I/O
- Organization: page program (typically 256-byte pages); sector/block erase (commonly 4 KB sectors and larger blocks)
- Features: hardware write protection, status register, deep power-down for low standby power
- Supply: voltage range and temperature grade vary by device; “IRR” indicates Industrial-grade packaging/temperature
- Package: small 8-pin package commonly used for SPI Flash devices
For exact electrical specs, timing, available modes, and pinout, refer to the GD25B256EFIRR datasheet.

Features

GD25B256EFIRR is a 256‑Mbit serial SPI flash memory from GigaDevice. Key features (highlights):
- Capacity: 256 Mbit (32 MB) of non-volatile storage
- Interface: Serial SPI (standard and fast read)
- Voltage and temp: 2.7–3.6 V operation; industrial temp range (-40°C to 85°C)
- Package: 8-pin RoHS-compliant package
- Operations: 256-byte page programming; erase by sectors (4 KB) and blocks (64 KB); chip erase option
- Data protection: software write protection and hardware block protection
- Power: low-power modes including deep power-down with fast wake
- Reliability: datasheet-specified endurance and data retention
Note: For exact electrical specs (read speeds, exact P/E cycles, timings, and sector/block details), consult the GD25B256EFIRR datasheet.

Package

GD25B256EFIRR uses an 8-pin SOP (SOIC) package, RoHS-compliant.

Pinout

- Pin count: 8 pins (SOIC-8/SOP-8)
- Function: 256-Mbit serial SPI NOR flash memory (non‑volatile storage) for firmware/data. Interfaces over SPI (CS, CLK, DI/MOSI, DO/MISO) plus WP, HOLD, VCC, GND; supports standard flash operations such as Read/Fast Read, Page Program, Sector/Block/Chip Erase, Write Enable/Disable, Read/Write Status, and Deep Power-Down.

Manufacturer

- Manufacturer: GigaDevice Semiconductor Inc. (GigaDevice).
- What kind of company: A Beijing-based fabless semiconductor company that designs and markets flash memory ICs (e.g., SPI/NOR/NAND flash) and microcontrollers, outsourcing fabrication to foundries.

Application

GD25B256EFIRR is a 256-Mbit SPI serial flash. Common applications:
- Storing firmware and boot code for microcontrollers
- External program/data memory for embedded systems
- Firmware updates and recovery
- Non-volatile storage for configuration, logs, and assets (fonts/graphics)
- Used in IoT, consumer electronics, networking equipment, and other embedded systems needing reliable non-volatile storage
