– Home appliances
– Smart sensors
– Fire and security systems
– Switched-mode power supply and power
management
– Uninterruptible Power Supply (UPS)
– Solar and wind power generator
– Power metering
– Motor control (ACIM, BLDC, PMSM, SR, stepper)
– Handheld power tools
– Circuit breaker
– Medical device/equipment
– Instrumentation
– Lighting
• DSC based on 32-bit 56800EX core
– Up to 100 MIPS at 100 MHz core frequency
– DSP and MCU functionality in a unified, C-efficient
architecture
