概要

Description

GD25LQ64ENIGR is a 64-Mbit serial flash memory from GigaDevice, intended for firmware storage, code boot, and data logging. It uses a serial SPI interface (supports standard SPI and dual/quad I/O read modes) and stores 8 MB of non-volatile data.
Key points:
- Capacity and addressing: 64 Mbit with 3-byte addressing (up to 16 MB address space, suitable for current MCU interfaces).
- Organization and operations: 256-byte page programming; erase operations for 4 KB sectors, 32 KB/64 KB blocks, and a full-chip erase.
- Performance: fast read options, high clock rates in drive-by-mode families; supports Deep Power-Down to save energy.
- Endurance and retention: typical program/erase endurance in the tens to hundreds of thousands of cycles; data retention typically many years.
- Power and packaging: operates from a single supply in the ~2.7–3.6 V range (variants exist); packaged in an 8-pin ENIGR form factor.
Typical uses: firmware storage, boot loaders, and data logging in microcontroller-based systems.

Features

Key features of GD25LQ64ENIGR (64 Mbit serial flash):
- Density: 64 Mbit (8 MB) of non-volatile flash memory.
- Interface: SPI-compatible with standard, dual-SPI, and quad-SPI I/O modes.
- Supply and range: 2.7–3.6 V operation (3.3 V nominal); -40 °C to 85 °C industrial temp range.
- Read speed: Fast/continuous read up to 104 MHz; supports various read modes.
- Organization: 256-byte page size; 4 KB sectors; 64 KB blocks (and sector/block protection options).
- Program/erase: Page program (256 bytes); sector erase; block erase.
- Power modes: Deep power-down for low current; normal standby modes.
- Security and protection: Write enable, status register, block/sector protection, and security features.
- Packaging: 8-pin RoHS-compliant package (e.g., SOIC/8-pin variants).
- Reliability: Data retention typically long-term; erase/write endurance in the typical flash range (consult datasheet for exact figures).
Note: Always verify exact electrical/timing figures in the latest datasheet for kernel design margins.

Package

GD25LQ64ENIGR uses an 8-pin SOP (SOIC-8) package; RoHS-compliant, supplied in Tape & Reel.

Pinout

- Pin count: 8 pins (SOP-8).
- Function: 64-Mbit serial flash memory (non-volatile) with an SPI-compatible interface (CS, MOSI, MISO, SCK) plus WP and HOLD pins, used to store firmware/data.
