These DSP devices feature a modified Harvard architecture supported by one program bus and two on-chip data buses.
This bus structure is supported by two address generators and six register pointers to ensure that the 20 MIPS DSP CPU is continually active.
The Z893X3 DSP family is designed to provide a complete DSP and control system on a single chip.
By integrating various peripherals, such as a high-speed 4-channel, 8-bit A/D, an SPI, three timers with PWM and WDT support, the Z893X3 family provides a compact system solution and reduces overall system cost.
