概述
Description
GD25B16ETIGR is GigaDevice’s 16-Mbit serial flash memory in the GD25B16 family. It uses a standard 8-pin SPI (single‑bit) interface for storing firmware and data. The device operates at 2.7–3.6 V and is offered in an industrial temperature range with RoHS-compliant packaging (suffix ETI/GR). Key features include Read and Fast Read, Page Program (256-byte pages), Sector/Block/Chip Erase, Write Enable/Disable, and Read/Write Status Register, along with write protection via status/block-protection bits and HOLD/WP pins. Common uses are boot code storage, embedded firmware, and data logging in microcontroller systems. For exact timings, voltage, packaging, and command details, consult the GD25B16ETIGR datasheet.
