Architecture overview

SPEAr300

Main features:

● Supports the following SPI-compatible Flash and EEPROM devices:

– STMicroelectronics M25Pxxx, M45Pxxx

– STMicroelectronics M95xxx, except M95040, M95020 and M95010

– ATMEL AT25Fxx

– YMC Y25Fxx

– SST SST25LFxx

● Acts always as a SPI master and up to 2 SPI slave memory devices are supported

(through as many chip select signals), with up to 16 MB address space each

● SMI clock signal (SMICLK) is generated by SMI (and input to all slaves)

● SMICLK can be up to 50 MHz in fast read mode (or 20 MHz in normal mode). It can be

controlled by 7 programmable bits.
