PRODUCT DESCRIPTION

The SST45VF512, SST45VF010 and SST45VF020 are manufactured with SST’s proprietary, high performance CMOS SuperFlash technology. The Serial Flash is organized as 16 sectors of 4096 Bytes for SST45VF512, 32 sectors of 4096 Bytes for the SST45VF010 and 64 sectors of 4096 Bytes for the SST45VF020. The memory is accessed for Read or Erase/Program by the SPI bus compatible serial protocol. The bus signals are: serial data input (SI), serial data output (SO), serial clock (SCK), write protect (WP#), chip enable (CE#), and hardware reset (RESET#).

The SST45VFxxx devices are offered in 8-pin SOIC package. See Figure 1 for the pinout.
