概述

Description

GD25B64CSIGR is a GigaDevice 64-Mbit serial NOR flash memory with an SPI interface. It’s used to store firmware, configuration, or data in embedded systems and can be embedded alongside microcontrollers or processors.
Key points:
- Density: 64 Mbit (8 MBytes)
- Interface: standard SPI (single I/O); clock up to ~104 MHz; modes 0–3
- Supply: 2.7–3.6 V
- Package: 8-pin SOP (SIGR denotes RoHS-compliant package)
- Memory organization: 256-byte page size; 4 KB sectors; 64 KB blocks; full-chip erase
- Operations: Read, Fast Read; Page Program (up to 256 bytes); Write Enable/Disable; sector/block/chip erase
- Features: Write protection, status registers (WIP/WEL), Deep power-down, typical low-power operation
- Applications: bootloaders, firmware storage, configuration data, nonvolatile code storage
Note: exact features/speeds may vary by revision. For precise electrical characteristics and timing, consult the latest datasheet.
