Digital Signal Controller

The MC56F825x/MC56F824x is a member of the 56800E core-based family of digital signal controllers (DSCs). It combines, on a single chip, the processing power of a DSP and the functionality of a microcontroller with a flexible set of peripherals to create a cost-effective solution. Because of its low cost, configuration flexibility, and compact program code, it is well-suited for many applications. The MC56F825x/MC56F824x includes many peripherals that are especially useful for cost-sensitive applications, including:

? Industrial control

? Home appliances

? Smart sensors

? Fire and security systems

? Solar inverters

? Battery chargers and management

? Switched-mode power supplies and power management

? Power metering

? Motor control (ACIM, BLDC, PMSM, SR, and stepper)

? Handheld power tools

? Arc detection

? Medical devices/equipment

? Instrumentation

? Lighting ballast

The MC56F825x/MC56F824x supports program execution from internal memories. Two data operands per instruction cycle can be accessed from the on-chip data RAM. A full set of programmable peripherals supports various applications. Each peripheral can be independently shut down to save power. Any pin, except Power pins and the Reset pin, can also be configured as General Purpose Input/Outputs (GPIOs). On-chip features include:

? 60 MHz operation frequency

? DSP and MCU functionality in a unified, C-efficient architecture

? On-chip memory

– 56F8245/46: 48 KB (24K x 16) flash memory; 6 KB (3K x 16) unified data/program RAM

– 56F8247: 48 KB (24K x 16) flash memory; 8 KB (4K x 16) unified data/program RAM

– 56F8255/56/57: 64 KB (32K x 16) flash memory; 8 KB (4K x 16) unified data/program RAM

? eFlexPWM with up to 9 channels, including 6 channels with high (520 ps) resolution NanoEdge placement

? Two 8-channel, 12-bit analog-to-digital converters (ADCs) with dynamic x2 and x4 rogrammable amplifier, conversion time as short as 600 ns, and input current-injection protection

? Three analog comparators with integrated 5-bit DAC references

? Cyclic Redundancy Check (CRC) Generator

? Two high-speed queued serial communication interface (QSCI) modules with LIN slave functionality

? Queued serial peripheral interface (QSPI) module

? Two SMBus-compatible inter-integrated circuit (I2C) ports

? Freescale’s scalable controller area network (MSCAN) 2.0 A/B module

? Two 16-bit quad timers (2 x 4 16-bit timers)

? Computer operating properly (COP) watchdog module

? On-chip relaxation oscillator: 8 MHz (400 kHz at standby mode)

? Crystal/resonator oscillator

? Integrated power-on reset (POR) and low-voltage interrupt (LVI) and brown-out reset module

? Inter-module crossbar connection

? Up to 54 GPIOs

? 44-pin LQFP, 48-pin LQFP, and 64-pin LQFP packages

? Single supply: 3.0 V to 3.6 V
