概述

Description

GD25Q32EWIGR is a GigaDevice 32‑Mbit serial flash memory. It provides non-volatile storage accessed over SPI, with options for dual/quad I/O modes.
Key points:
- Capacity and organization: 32 Mb (4,194,304 B); 256‑byte page size; erasable in 4 KB sectors, 32 KB, 64 KB blocks, or the whole chip.
- Interfaces and speed: supports standard SPI, dual I/O, and quad I/O (QIO/DIO); up to about 104 MHz operation.
- Voltage and power: typically 2.7–3.6 V supply; includes deep power‑down and low‑power modes.
- Operations: write enable/disable, page program, sector/block/chip erase, read and fast read; status and protection registers available.
- Packaging: 8‑pin packages with RoHS-compliant suffix (WIGR in the part number refers to the specific package/trace variant).
- Applications: firmware/code storage for microcontrollers, boot ROM, data storage, or EEPROM replacement.
If you need exact timing, command set, and electrical characteristics, consult the GD25Q32E/WIGR datasheet.

Features

Key features of GD25Q32EWIGR (32M-bit serial flash, 8-pin):
- 32 Mbit (4 MB) of non-volatile memory
- SPI-compatible with Dual/Quad I/O and QPI modes for higher throughput
- Operating voltage: 2.7 V to 3.6 V
- High-speed read up to 104 MHz (SPI); supports fast read with dummy cycles
- Page program: 256-byte pages
- Erase types: 4 KB sectors; 32 KB and 64 KB blocks; chip erase
- Endurance: typically 100,000 P/E cycles; data retention ~20 years
- Low-power features: deep power-down mode; rapid wake
- Security/protection: status register, block protection (BP bits), write protection
- Temperature range: -40 °C to 85 °C (industrial)
- Package: 8-pin package (WIGR), RoHS-compliant
Note: exact electrical/timing figures may vary by revision; consult the datasheet for precise specs.

Package

GD25Q32EWIGR is in an 8-pin SOP (SOIC-8) package, RoHS-compliant.

Pinout

- Pin count: 8 pins (8-pin package, e.g., SOIC).
- Function: 32-Mbit SPI serial flash memory (GD25Q32E family). Pinout (typical 8-pin): 1 CS#, 2 DO (MISO), 3 WP#, 4 GND, 5 DI (MOSI), 6 CLK, 7 HOLD#, 8 VCC. WP# and HOLD# are active-low; VCC is the supply.

Manufacturer
