概述

Description

GD25LD20CEIGR is a GigaDevice 2‑Mbit serial NOR flash memory. It uses an SPI interface for read/write/erase, making it suitable for firmware and nonvolatile data storage in microcontroller systems. It comes in an 8‑pin SOP package and supports industrial temperature range (-40°C to 85°C).
Key specs:
- Capacity: 2 Mbit (256 KB)
- Interface: SPI (standard and fast read)
- Page/Erase: 256-byte page program; 4 KB sectors; 32 KB/64 KB blocks; chip erase
- Voltage: typically 2.7–3.6 V
- Clock: up to ~50 MHz
- Features: Write Enable, status register, hold, power-down
- Endurance/Data retention: ~100,000 write/erase cycles; ~20 years data retention
Typical uses: firmware/bootstrap storage, nonvolatile configuration data, and code storage in embedded systems. For exact electricals, timing, and command set, see the GD25LD20C/CE datasheet.

Features

Here are the key features of GD25LD20CEIGR:
- Density: 2 Mbit (256 KB)
- Interface: SPI-compatible serial flash
- Endurance/Retention: ~100,000 erase/program cycles; data retention >20 years
- Memory organization: 256-byte page size; 4 KB sectors; 64 KB blocks
- Power: 2.7V–3.6V operation; low-power modes including deep power-down
- Temperature range: -40°C to 85°C
- Packaging: 8-pin RoHS-compliant package (EIGR code indicates package type)
- Security/Protection: hardware write protection and standard security features

Note: The above summarizes common GD25LD20C-series features; always refer to the official datasheet for exact timing and mode details.

Package

8-pin SOP (SOIC-8) package.

Pinout

- Pin count: 8 pins (SOP-8)
- Function: Serial SPI flash memory (non-volatile) with about 2 Mbit capacity; uses standard SPI signals: CS, SCK, SI (MOSI), SO (MISO), plus WP, HOLD, VCC, and GND.

Manufacturer

Manufacturer: GigaDevice Semiconductor (GigaDevice).
Type of company: A Chinese fabless semiconductor company that designs nonvolatile memory and microcontroller products (e.g., serial flash like GD25 series) and outsources manufacturing to contract foundries.

Application

Applications:
- Code and data storage for MCUs in embedded systems
- Firmware/bootloader storage and updates
- Non-volatile data logging and configuration memory
- Small-capacity storage for IoT devices, wearables, and consumer electronics
- Auxiliary or automotive peripheral memory in embedded systems

Equivalent

GD25LD20CEIGR is a 2 Mbit, 3.3V SPI NOR flash. Common equivalents (same density and interface) include:
- Winbond W25Q20BV/W25Q20DL
- Macronix MX25L2006E (MX25L2006D/UME variants)
- Puya P25Q20U
They share the 8-pin SPI NOR flash design and command set; verify exact package, voltage, and timing in the datasheet cross-reference.
