概述

Description

GD25LQ32DQIGR is a 32‑Mbit serial flash memory from GigaDevice (GD25LQ32 family). It provides a SPI‑compatible interface with Standard, Dual I/O, and Quad I/O (QPI) modes for high‑speed data access. It operates on a supply of 2.7–3.6 V (industrial grade variant). Memory organization is 4 MB with 256‑byte pages, 4 KB sectors, and larger erase blocks (including chip erase). Typical read speeds in SPI mode reach up to about 104 MHz; QPI enables even higher throughput. It supports fast read, Deep Power‑Down, and standard write protections via WP/HOLD pins. The suffix IG/R indicates Industrial grade, RoHS‑compliant packaging in an 8‑pin package. Common applications include firmware storage and boot code for microcontrollers, as well as data storage in embedded systems. If you need exact timing, voltage, and command lists, consult the GD25LQ32D datasheet.

Features

Key features of GD25LQ32DQIGR:
- Capacity: 32 Mbit (4 MB) serial flash.
- Interface: Quad I/O SPI (DQI) with support for standard SPI and Dual/Quad I/O modes.
- Voltage and Temp: 2.7–3.6 V operation; Industrial grade temperature range -40°C to 85°C.
- Package: 8-pin SOIC (DQIGR variant).
- Memory organization: 256-byte page; sectors: 4 KB; blocks: 32 KB and 64 KB.
- Performance: Fast read up to 104 MHz; Quad I/O up to similar speeds.
- Endurance/Retention: ~100,000 P/E cycles; data retention ~20 years.
- Power features: Deep power-down mode; power-on reset; standard WIP/WEL status tracking.
- Security/Protection: Status registers with Quad Enable (QE) bit; Write Protection and BP (block protect) mechanisms.
- Addressing: 3-byte addressing (4-byte addressing mode available for larger devices if needed).
Also supports typical erase/program operations, suspend/resume of program/erase, and standard industry-wide command set for flash memory.
