ADuC7000 family is based on ARM7TDMI core with implemented some very unique features which are not seen in any other vendor:12-Channel, 12-bit, 1MSPS ADC, Quad 12-bit Voltage Output DACs, On-Chip 20ppm/°C Voltage Reference, On-Chip Temperature Sensor (±3°C), Three-phase 16-bit PWM generator, PLA – Programmable Logic (Array)
PLUS:
Fast core runs at up to 45Mhz from single 32Khz crystal.
Unique analogue peripherials: ADC/DAC 12 bit with 1Msps, 3-phase PWM generator
very useful for motor control applications
MINUS:
Only 62KB internal Flash, 8KB SRAM
No cache memory. No DMA.
