Description
GD25B64CSIGR is a 64-Mbit serial (SPI) flash memory from GigaDevice (GD25B64C family). It provides 8 MBytes of non-volatile storage accessible over a standard SPI bus (MOSI/MISO, SCLK, CS). Key features: typical page size 256 bytes; supports read (including fast read), page program, and erase operations (4 KB sectors, 32 KB/64 KB blocks, and full-chip erase); requires a Write Enable (WREN) before programming/erasing and exposes a status register with a WIP bit. Supply voltage is in the common SPI flash range (around 2.7–3.6 V), with high-speed SPI operation possible (clock rates in the tens of MHz, depending on device variant and setup). Package: 8-pin SOP (SIL/ SOIC) with RoHS-compliant packaging (suffix “SIGR”). Applications include firmware storage, bootloaders, and data logging in embedded systems. For exact electrical specs, timing, and the complete command set, consult the GD25B64C datasheet; the “SIGR” suffix denotes the SOP-8 RoHS package variant of the device.
