GD25R64ESIGR – Serial NOR Flash – GigaDevice

The GigaDevice GD25R64ESIGR is a 64Mbit (8MB) RPMC-enabled SPI Serial NOR Flash memory in an SOP-8 (208mil) package, supporting Standard/Dual/Quad SPI and a 2.7V-3.6V supply for secure code storage in PC and embedded applications.

The GigaDevice GD25R64ESIGR is a 64Mbit (8 Mbyte) serial NOR Flash memory device from GigaDevice’s GD25R RPMC family of high-security SPI Flash. The GD25R series is a 3V, 4KB uniform-sector device that integrates a hardware Replay Protected Monotonic Counter (RPMC) function, making it a popular choice for platform security and secure boot in PC and embedded designs. It communicates over a Serial Peripheral Interface and supports Standard, Dual, and Quad SPI modes for flexible, high-throughput access.

This device is supplied in an industry-standard SOP-8 (208mil) package, operates from a single 2.7V-3.6V supply, and is rated for the industrial temperature range. With proven endurance and long data retention, the GD25R64ESIGR is well suited to applications that require trusted, tamper-resistant non-volatile storage.
