概要

Description

GD25Q20CEIGR is a GigaDevice 2-Mbit SPI serial flash memory. It’s used to store code or data in embedded systems.
Key points:
- Capacity: 2 Mb (256 KB).
- Interface: Standard SPI (also supports faster/parallel/quad modes on related parts); 8-pin package.
- Voltage: Typically 2.7–3.6 V.
- Performance: Read up to high MHz range (commonly ~104 MHz); supports standard and fast read.
- Memory organization: 256-byte-page programming; sectors/blocks for erasing (e.g., 4 KB sectors; 32/64 KB blocks as applicable).
- Power and features: Deep Power-Down mode, Hold and WP# pins for protection; WIP/WEL status bits.
- Endurance/retention: About 100,000 P/E cycles with data retention on the order of years (often ~10–20 years).
- Temperature: Industrial range typically -40 to 85°C.
- Applications: Firmware storage, boot memory, microcontroller data/log storage.
Note: “GR”/“EI” suffixes indicate RoHS-compliant packaging and related grade options.
