1 SERIAL FLASH MEMORY
GENERAL DESCRIPTION
The W45B012 is manufactured with Winbond’s high performance CMOS WinFlash technology. The
Serial Flash is organized as 32 sectors of 4096 Bytes for the W45B012. 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). This device is offered in 8L SON and 32L PLCC package.
