Freescale TWR-56F8400 32位数字信号控制器开发方案

The MC56F8400 Tower 32-bit MCU Module (TWR-56F8400) is an evaluation, demonstration and development board. The TWR-56F8400 can operate stand-alone or as the main control board in a Tower system with peripheral modules. It can also be used as the main control board with an APMOTOR56F8000E motor control board.

TWR-56F8400 MCU模块主要特性:

32 bit Digital Signal Controller module featuring MC56F84789

Tower compatible

Selectable Power sources: o USB on 56F8400 card

o Barrel connector on 56F8400 card

o Motor control board plug direct to 56F8400 card, no Tower connection, plug Motor control to nine volts

o Tower elevator board (USB or Barrel on Primary side)

Filtered power for VDDA and VSSA on the 32-bit MC56F84789DSC

MC56F84789 DSC (Digital Signal Controller) in an 100 LQFP package

Optional 8 MHz crystal circuit for the MC56F84789 DSC

9 LEDs controlled by the MC56F84789 DSC

Motor Control Board connector for the APMOTOR56F8000E motor control board

Auxiliary Signal connector

Four Thermistors for single ended or differential analog inputs to the MC56F84789 DSC

CAN transceiver, header, and termination

Two push buttons for user input or interrupts to the MC56F84789 DSC

Reset push button for the MC56F84789 DSC

JTAG header for the MC56F84789 DSC with header to disconnect from OSBDM/OSJTAG

Headers to connect SCI signals to either USB bridge with CDC(one channel) or elevator board (two channels) or connect one to each

Expansion via Primary Elevator connector

MC9S08JM60 (‘JM60) MCU with a 4 MHz crystal provides: o Open Source Debug (OSBDM/OSJTAG) circuit

o USB to SCI bridge with CDC and other techniques supported by third parties

o Simultaneious OSBDM/OSJTAG and USB to SCI bridge functions with no header required to select

o Bootloader enable header allows easy upgrade to latest S08 firmware pushed down by CodeWarrior

o BDM header for the MC9S08JM60 MCU

o Status and Target Power indicator LEDs

o Control of semiconductor switch to enable power to board from USB

o Voltage translators between 5V MC9S08JM60 MCU chip and 3.3V MC56F84789 DSC chip
