概述

Description

GD25Q40EEIGR is a Gigadevice 4 Mbit serial flash memory (GD25Q40E family). It uses a standard SPI-compatible interface to store firmware and data for embedded systems. Key features:
- Capacity: 4 Mbit (512 KB)
- Package: 8-pin, RoHS-compliant (likely SOP8)
- Supply: typically 2.7–3.6 V
- Performance: fast read up to around 104 MHz; supports standard SPI read, page program (256 bytes), and sector/block erases (4 KB, 32 KB, 64 KB) plus chip erase
- Operations: write enable/disable, status register with write protection, power-down/deep power-down modes
- Compatibility: JEDEC-compatible IDs; optional dual/quad I/O modes on some variants
Uses: boot code storage, firmware updates, and data storage in microcontroller and embedded designs. For exact timing, voltage, temperature range, and packaging details, consult the official datasheet.

Features

Here are the typical features of GD25Q40EEIGR:
- 4 megabit (512 KB) serial flash memory
- SPI interface (SI, SO, SCK, CS) in an 8-pin package
- 3-byte addressing (no 4-byte address needed)
- Fast Read up to ~104 MHz
- Page program: up to 256 bytes
- Erase granularity: 4 KB sectors; 32 KB and 64 KB blocks; Chip erase option
- Power-down mode with fast wake-up
- Hardware protection: block/sector protection; WP# and HOLD# pins
- Endurance: typical around 100,000 P/E cycles; data retention ~years
- Supply voltage: 2.7–3.6 V
- Operating temp ranges available (industrial grade options, e.g., -40°C to 85°C)
- RoHS-compliant,GD25Q40E family in an 8-pin SOP (IGR) package
Notes:
- Specifics (e.g., exact voltage/ temp ranges, endurance) may vary by lot/grade; always refer to the latest datasheet for exact figures.

Package

The GD25Q40EEIGR comes in an 8-pin SOP (SOIC-8) package (lead-free/RoHS compliant).

Pinout

- Pin count: 8 pins (SOP-8).
- Function: 4 Mbit serial SPI flash memory (GD25Q40E family). Used to store code/data; supports standard SPI and Dual/Quad I/O modes. Pinout typically: CS, CLK, DI (MOSI), DO (MISO), WP#, HOLD#, VCC, GND. Common operations include Read, Fast Read, Page Program, Sector/Evac/Erase commands, and Chip Erase.
