Preliminary W45B012

´ 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.
