Demonstration board for 9S12XHY256
The DEMO9S12XHY256 is a demonstration board for the MC9S12XHY256 microcontroller. Application development is quick and easy with the integrated USB-BDM, sample software tools, and examples. An optional BDM_PORT port is also provided to allow use of a BDM_PORT cable. A 40-pin connector provides access to most IO signals on the target MCU.
Application development and debug for the target MC9S12XHY256 is supported through the background debug mode (BDM) interface. The BDM interface consists of an integrated USB-Multilink BDM and a 6-pin interface header (BDM_PORT). The BDM_PORT header allows connecting an external HCS12 BDM cable. Refer to the MC9S12XHY Reference Manual for details and capabilities of the BDM.
The DEMO9S12XHY256 board features an integrated USB-BDM. The integrated BDM supports application development and debug via background debug mode. All necessary signals are provided by the integrated BDM. A USB, type B, connector provides connection from the target board to a host PC.
The integrated USB-Multilink BDM provides power and ground to the target board eliminating the need for external power. Power from the USB-Multilink BDM is derived from the USB bus; therefore, total current consumption for the target board, and connected circuitry, must not exceed 500mA. This current limit describes the current supplied by the USB cable to the BDM circuit, the target board, and any connected circuitry. Excessive current drain will violate the USB specification causing the bus to disconnect. Damage to the host PC USB hub or the target board may result.
The MC9S12XHY family is an optimized, automotive, 16-bit microcontroller product line focused on low-cost and high-performance. This family is intended to bridge from low-end 16-bit microcontrollers, such as the MC9S12HY family, to high-performance 32-bit solutions. The MC9S12XHY family is targeted for the lower end of automotive instrument cluster applications; it includes support for CAN and LIN/J2602 communication and delivers typical cluster requirements such as stepper motor control with stepper stall detection (SSD) and LCD driver.
Key Applications: Automotive (Basic / Low Line Instrument Cluster, Heating Ventilation and Air Conditioning (HVAC), Automotive Audio Systems)
