Notes: exact block sizes and available protection options can vary by revision; refer to the latest datasheet for precise specs.

- Pin count: 8 pins (8-pin SOP)
- Pinout and function (pin 1 to 8, order may vary by package, but function is standard for GD25Q32E family):
1. CS# — Chip Select (active low)
2. DO — MISO (Data Out)
3. WP# — Write Protect (active low)
4. GND — Ground
5. DI — MOSI (Data In)
6. CLK — Serial Clock
7. HOLD# — Hold (active low)
8. VCC — Power supply (3.3V typical; 2.7–3.6V range)
Note: GD25Q32EWIGR is a 32M-bit SPI flash; these pins provide the standard SPI interface plus optional features via WP# and HOLD#.
