Description

GD25B16ETIGR is a GigaDevice 16‑Mbit serial flash memory (2 MBytes) accessed over a standard SPI interface. It provides non‑volatile storage for code and data, with common features such as 256‑byte page programming, 4 KB sectors and 64 KB blocks erase, write enable/disable, and status/config registers with protection. It supports typical SPI command sequences (READ, FAST READ, PAGE PROGRAM, SECTOR/ BLOCK ERASE, etc.) and offers low‑power modes and deep power‑down. The ETIGR suffix indicates packaging (generally an 8‑pin package) and an industrial/extended temperature grade. Operating voltage is typically 2.7–3.6 V (variant dependent). Use cases include firmware storage and bootloaders, configuration data, and data logging in microcontroller systems. For exact timing, endurance, voltage range, pinout, and packaging details, consult the GD25B16ETIGR datasheet and packaging documentation.

Features

Here are the typical features of GD25B16ETIGR (GigaDevice 16-Mbit SPI Serial Flash, ROHS, 8-pin):
