Preliminary W45B512
512K × 1 SERIAL FLASH
GENERAL DESCRIPTION
The W45B512 is manufactured with Winbonds’ high performance CMOS WinFlash technology. The
Serial Flash is organized as 16 sectors of 4096 Bytes for the W45B512. 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.
