Main features:
●
●
●
●
Supports the following SPI-compatible Flash and EEPROM devices:
–
–
–
–
–
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.
