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

– Handheld power tools
– Circuit breaker
– Medical device/equipment
– Instrumentation
– Lighting

– 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
• Analog

dynamic x2, x4 programmable amplifier
– One 20-channel, 16-bit ADC
– Four analog comparators with integrated 6-bit DAC
references
– One 12-bit DAC
• PWMs and timers

at standby mode) and 32 kHz
– Crystal / resonator oscillator
• System
– DMA controller
– Integrated power-on reset (POR) and low-voltage
interrupt (LVI) and brown-out reset module
– Inter-module crossbar connection
– JTAG/enhanced on-chip emulation (EOnCE) for
unobtrusive, real-time debugging
Freescale reserves the right to change the detail specifications as may be
required to permit improvements in the design of its products.
