Description
GD25LR256EYIGR is a 256‑Mbit serial NOR flash memory from GigaDevice, designed for non-volatile code and data storage. Key points:
- Interface: SPI, with dual/quad SPI options for higher throughput.
- Density and organization: 256 Mbit (32 MB); 256-byte page size; 4 KB sectors; 64 KB and/or 256 KB blocks for erase.
- Voltage and temp: typically 2.7–3.6 V operation; industrial temperature range (-40 to 85 °C).
- Features: fast read modes, power-down/deep power-down, hardware write protection and security features, and standard read/write/erase commands.
- Package: 8-pin package (suffix indicates specific packaging/RoHS/temperature options).
Common use: firmware storage, boot memory, and non-volatile data storage in microcontrollers, FPGAs, and SoCs. For exact timing, command set, and electrical specs, consult the official GD25LR256E datasheet for the EYIGR variant.
