Chip used
 DSP56800E Family General Purpose 16-bit fixed point (six
members).
 DSP56800E Introduced in 2000 as improved version of
DSP568500 family
 Lower Power Consumption
 Enhanced peripherals
 Higher MIPS
 Many Peripheals:
 SCI to communicate with devices using RS232
 SPI to communicate with CODEC or EEPROM (needs a clock).
 DMA to communicate between memory and external device
