Freescale Semiconductor  
Data Sheet: Advance Information  
MC56F844XX  
MC56F844xx Advance  
Information  
Supports the 56F84462VLH,  
56F84452VLH, 56F84451VLF,  
56F84442VLH, 56F84441VLF  
Features  
Analog  
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  
– Two high-speed, 8-channel, 12-bit ADCs with  
dynamic x2, x4 programmable amplifier  
– One 20-channel, 16-bit ADC  
– Up to four analog comparators with integrated 6-bit  
DAC references  
– One 12-bit DAC  
– 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  
PWMs and timers  
– One eFlexPWM module with up to 24 PWM outputs  
– Two 16-bit quad timer (2 x 4 16-bit timers)  
– Two Periodic Interval Timers (PITs)  
– One Quadrature Decoder  
– Two Programmable Delay Blocks (PDBs)  
Communication interfaces  
– Two high-speed queued SCI (QSCI) modules with  
LIN slave functionality  
– Two queued SPI (QSPI) modules  
– Two SMBus-compatible I2C ports  
– One flexible controller area network (FlexCAN)  
module  
– Circuit breaker  
– Medical device/equipment  
– Instrumentation  
– Lighting  
DSC based on 32-bit 56800EX core  
– Up to 60 MIPS at 60 MHz core frequency  
– DSP and MCU functionality in a unified, C-efficient  
architecture  
Security and integrity  
– Cyclic Redundancy Check (CRC) generator  
– Computer operating properly (COP) watchdog  
– External Watchdog Monitor (EWM)  
On-chip memory  
– Up to 160 KB (128 KB + 32 KB) flash memory,  
including up to 32 KB FlexNVM  
Clocks  
– Two on-chip relaxation oscillators: 8 MHz (400 kHz  
at standby mode) and 32 kHz  
– Crystal / resonator oscillator  
– Up to 24 KB RAM  
– Up to 2 KB FlexRAM with EEE capability  
– 60 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  
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
