SK Hynix Memory Catalog Reveals 1.I have a Linux receiver that wouldn't flash properly, possibly due to a dodgy bootloader and thought I would try to replace the winbond chip, I have a GQ-4x programmer that I used to use for programming TSOP and luckily had an adaptor for it to fit the winbond.I have identified a replacement chip as 25Q32FVSIG.If needed a pullup resister on /CS can be used to accomplish this. The /CS input must track the VCC supply level at power-up (see “Write Protection” and figure 38). When /CS is brought low the device will be selected, power consumption will increase to active levels and instructions can be written to and data read from the device.Īfter power-up, /CS must transition from high to low before a new instruction will be accepted. When deselected, the devices power consumption will be at standby levels unless an internal erase, program or write status register cycle is in progress. When /CS is high the device is deselected and the Serial Data Output (DO, or IO0, IO1, IO2, IO3) pins are at high impedance. The SPI Chip Select (/CS) pin enables and disables device operation. – Volatile & Non-volatile Status Register Bits

– 3X256-Byte Security Registers with OTP locks – Discoverable Parameters (SFDP) Register – Power Supply Lock-Down and OTP protection

– Top/Bottom, 4KB complement array protection – 104MHz Dual SPI / 80MHz Quad SPI clocks All devices are offered in space-saving packages. The device operates on a single 2.7V to 3.6V power supply with current consumption as low as 4mA active and 1μA for power-down. They are ideal for code shadowing to RAM, executing code directly from Dual/Quad SPI (XIP) and storing voice, text and data. The 25Q series offers flexibility and performance well beyond ordinary Serial Flash devices. The W25Q32BV (32M-bit) Serial Flash memory provides a storage solution for systems with limited space, pins and power. The 25032BVSIG (32M-bit) Serial Flash Memory provides a storage solution for systems with limited space, pins and power.
