| Abstract: | This paper introduces the basic operation of C8051F340 MCU of U.S. CYGNAL company working in the SPI efficient serial data interface mode. The hardware interface of the MCU and ATMEL＇s FLASH ROM chip called AT45DB 161D with SPI interface is designed. Read and write operations about this serial of memory under SPI mode in detail are introduced. This paper has a certain representativeness and practicality for the operation of FLASH ROM chip with MCU. |
