GD25Q32CTIG

GD25Q32CTIG is GigaDevice’s 32-Mbit serial flash memory (GD25Q32C family) in an 8‑pin package (CTIG). It uses an SPI-compatible interface (standard SPI; some variants support dual/quad IO modes) to store firmware and data.
Key features:
- 3.3 V operation; 4 MB user data
- 256‑byte page size; 4 KB sectors; 64 KB blocks
- Read, Fast Read, Page Program; Sector/Block/Chip Erase; Write Enable/Disable
- Status and Identification registers; deep power-down; hold and write-protect features
- Data retention typically ~20 years; erase/program endurance ~100k cycles
- Clock up to ~104 MHz (Quad/PIO modes may enable higher effective bandwidth)
Typical applications:
- Firmware/boot code storage for MCUs and microcontrollers
- Embedded system data storage and code updates
Note: exact timings, pinout, voltage range, and mode support vary by variant; consult the GD25Q32CTIG datasheet for precise specifications.

GD25Q32CTIG is an 8-pin serial flash memory (32 Mbit, 4 MB) with a 4‑wire SPI interface.
Pinout (8 pins):
- 1 CS# — Chip Select (active low)
- 2 SO / DO — Data Out (MISO)
- 3 GND — Ground
- 4 SI / DI — Data In (MOSI)
- 5 SCK — Serial Clock
- 6 WP# — Write Protect (active low)
- 7 HOLD# — Hold (active low)
- 8 VCC — Power Supply
Note: WP# and HOLD# are optional protections/hold controls; SPA (CS, SCK, DI, DO) form the standard SPI interface.
