GD25D20CKIGR – Serial NOR Flash – GigaDevice

The GD25D20CKIGR is a GigaDevice 2 Mbit (256K x 8) serial NOR flash memory with Standard SPI and Dual I/O interface, 2.7V-3.6V supply, in a compact USON-8 1.5 x 1.5 mm package.

The GD25D20CKIGR is a 2 Mbit (2,097,152-bit) Serial NOR Flash memory from GigaDevice, part of the GD25D 3.3V Uniform Sector Standard and Dual Serial Flash family. Organized as 256K x 8 bits, it provides reliable non-volatile code and data storage for cost- and space-constrained embedded designs. The “KIGR” ordering option delivers the device in the industry-compact USON-8 1.5 x 1.5 mm package, making it well suited to applications where PCB area and battery life are critical.

The device supports Standard SPI and Dual I/O operation, with a maximum clock frequency of 104 MHz in standard (single-I/O) mode and 80 MHz in dual-I/O mode, across a 2.7V to 3.6V supply range. It uses a uniform 4 KB sector architecture with 256-byte page programming, and includes a factory-programmed Unique ID and hardware Write Protect (WP#) support.
