GD5F1GM7UEY1GR SPI NAND Flash Memory
The GD5F1GM7UEY1GR is a 1Gb SLC SPI NAND Flash memory from GigaDevice designed for cost-effective, high-density non-volatile storage in space-constrained embedded systems. It operates from a 2.7V to 3.6V supply and supports Standard, Dual, and Quad SPI interfaces with clock frequencies up to 133MHz, enabling fast data transfer and efficient code or data storage. The device features internal ECC that is user-selectable and enabled by default, enhancing reliability by detecting and correcting errors during reads without requiring host-side ECC management.
This SPI NAND integrates a 2KB page size with a 64-byte spare area when internal ECC is enabled, and includes a 2KB cache register to accelerate random reads and copy-back operations, simplifying garbage collection and wear leveling for the host. It offers advanced features such as a 20KB one-time programmable (OTP) region, hardware and software write protection, and a power-on read function that automatically loads the first page to cache for fast boot. The low pin count (8 pins) and consistent pinout across densities make board design and migration straightforward.
Alternative SPI NAND Models
1. Micron MT29F1G01ABAFDWB: 1Gb SLC SPI NAND Flash with x1/x2/x4 interface, 3.3V supply, and robust reliability for embedded storage and code shadowing.
2. Winbond W25N01GVZEIG: 1Gb SLC QSPI NAND Flash featuring 2.7V–3.6V operation and up to 83MB/s continuous read, ideal for XIP and data logging in compact designs.
3. Macronix MX35LF1GE4AB: 1Gb SLC serial NAND with internal 4-bit ECC, 104MHz x1/x2/x4 interface, and 8-WSON 8x6mm package for reliable, low-power embedded applications.
