简 介:Preliminary W45B012 1M × 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.
