概要

Description

GD25LB256EYIGR is a 256‑Mbit serial NOR flash memory from GigaDevice (GD25LB256E family). It provides non‑volatile storage for firmware and data in embedded systems and is accessed via an SPI‑compatible interface. The device supports standard SPI and higher‑speed modes (dual/quad I/O in some configurations) and uses 4‑byte addressing to reach the full memory array. Typical flash operations include read/fast read, page programming, and sector/block erases, with security features such as write protection and status registers. The YIGR suffix denotes the specific package and temperature/ RoHS grade per GigaDevice’s naming conventions (e.g., an 8‑pin package with a defined temperature range). Common applications are microcontroller boot code storage, firmware updates, configuration data storage, and data logging in both consumer and industrial products.

Features

Key features of GD25LB256EYIGR:
- 256-Mbit serial flash memory (32 MB) with SPI-compatible interface
- Low-voltage operation: 2.7 V to 3.6 V
- Read modes: Standard, Fast, Dual I/O, and Quad I/O
- High-speed reads up to 104 MHz
- Write: 256-byte pages
- Erase: 4 KB sectors; larger blocks (64 KB and 256 KB)
- Power modes: Deep power-down and standby
- Protection: Hardware and software write protection; status register and memory protection features; WP# and HOLD# pins
- Endurance/retention: Typical 100k P/E cycles; data retention ~20 years
- Operating temperature: -40 °C to +85 °C (industrial)
- Packaging: 8-pin package (RoHS compliant)
Ideal for code boot/loading, firmware storage, and data logging in space- and power-constrained designs.
