Features
• ^{This family of digital signal controllers (DSCs) is}
based on the 32-bit 56800EX core. Each device
combines, on a single chip, the processing power of a
DSP and the functionality of an MCU with a flexible
set of peripherals to support many target applications:
– Industrial control
– 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 80 MIPS at 80 MHz core frequency
– DSP and MCU functionality in a unified, C-efficient
architecture
• ^{On-chip memory}
– Up to 128 KB (96 KB + 32 KB) flash memory,
including up to 32 KB FlexNVM
– Up to 16 KB RAM
– Up to 2 KB FlexRAM with EEE capability
– 80 MHz program execution from both internal flash
memory and RAM
– On-chip flash memory and RAM can be mapped
into both program and data memory spaces
