• Motorola Modular Development System (MMDS11)
  This powerful, full-featured emulation system supports the development of embedded systems based on an M68HC11 MCU.

• Motorola HC11 Evaluation System (EVS)
  Developers can use this EVS to economically design, debug, and evaluate target M68HC11-based systems.

• Motorola HC11 Serial Programmer SPGMR11)
  The Serial Programmer is used to program M68HC11 devices that contain an EPROM or EEPROM array.

• Motorola HC11 Evaluation Boards (M68HC11EVB and M68HC11EVBU)
  These low-cost boards, the M68HC11 Evaluation Board and the Universal Evaluation Board, help developers evaluate code destined for a subset of devices in the M68HC11 family of MCUs.

• Station module - This metal case allows easy access for installing or replacing emulation modules. The station module includes these items:
  
  
  • RS-232C serial cable (9-lead)
  • RS-232C adapter (9->25-pin)
  • two cables and 16 logic clips for selecting individual signals
  • built-in power supply (85 to 264 VAC)
  • The station module works across many devices of the M68HC11 family, and once purchased can be reused for any number of M68HC11 development projects.
  
  
  

  Note: The following device-specific components must be purchased separately from the station module. An emulator module or a target cabling component can often be adapted to a wide range of M68HC11 devices.

• Emulation module - Printed circuit board that plugs into the control board and fits inside the station module. The device-specific EM completes functionality for one or more M68HC11 MCUs.
• Target head - Adapter that plugs into the target system's MCU socket. Where necessary, it includes a TQ socket that aligns target-head guidepins with the target.
• Flex cable - Matched impedance ribbon cable that connects the EM to the target head.

• single chip - I/O only
• expanded - full bus access
• special test - expanded plus additional features.

• Platform board (PFB) - Printed circuit board that works across all devices of the M68HC11 family and which can be reused across all M68HC11 derivatives. Includes a low-cost assembler and interface software.
• Emulation module - Smaller printed circuit board that plugs onto the PFB to complete the Evaluation System functionality for one or more MCUs.
• Target head - Special adapter that plugs into the MCU socket of a target system.
• Flex cable - Ribbon cable that connects the EM to the target head.

M68HC11EVS software components include:

• IDE - The MMEVS IDE, which comes with the platform board, provides an editor, an assembler, ans a source-level debugger with graphical user interface to support target system emulation.
• IASM11,EVM11 - The IASM11 is an absolute assembler for DOS. The EVM11 is a absolute debugger for DOS. Each is shipped with the M68HC11 PFB.

Third-party software products are also available for use with the M68HC11EVS.

Third-party Software for the HC11EVS

The following steps help you put together a complete system. A table below, MMDS11 and M68HC11EVS Development Systems, helps with the specifics.

• Step 1. Identify the device to be emulated and its package type. The components that complete the development system or the evaluation system are ordered according to the device to be emulated.
• Step 2. Select the emulation module that goes with the device. Each device requires an EM. A particular EM can be adapted for multiple devices—which means you frequently will not need to order multiple emulation modules for multiple M68HC11 development or evaluation projects.
• Step 3. Select the device-specific flex cable. Flex cables are often reusable across devices and with multiple EMs, so you may not need to reorder this component.
• Step 4. Select the device-specific target head. Like flex cables, target heads are often reusable for other devices and EMs.

MMDS11 and M68HC11EVS Development Systems

Serial Programmer for HC11 MCUs (SPGMR11)

• Operate as a standalone programmer connected to a host computer. (In this case, a 5-volt power supply must be connected to the SPGMR11.)
• Connect a host computer to the MMDS11 station module. (In this instance, the MMDS11 supplies 5-volt power.)

An on-board programming-voltage circuit eliminates the need for an external 12-volt supply. The SPGMR11 also includes a +5-volt power cable and a DB9-to-DB25 connector adapter, along with programming software that runs on the host computer. One or two standard DB9 male/female cables are required to make the system connections.

Hardware and Software Components

• Serial programmer base unit (M68SPGMR11) – This small, lightweight box connects to the host computer's serial communication port via a standard 9-lead cable. If used as a standalone programmer, the base unit connects directly to a +5-volt DC power supply. If used with an MMDS11, the base unit connects to the MMDS with a 9-lead cable and a +5-volt power cable. (The +5-volt power cable is included with the MMDS11.)
• Programming adapter – Device-specific programming adapters enable the Serial Programmer to program a variety of M68HC11 microcontroller devices in various package configurations. Connectors on the programming adapter plug into connectors in the top of the serial programmer case. The programming adapter is ordered separately from the serial programmer base unit.

• Step 1. Order the Serial Programmer base unit. Regardless of the type of device to be programmed, the Serial Programmer base unit—M68SPGMR11—is required. The M68SPGMR11 is used across the full spectrum of devices that contain EPROM or EEPROM arrays.
• Step 2. Select the device-specific programming adapter kit. Device-specific programming adapters must be purchased separately from the base unit.

HC11 Evaluation Boards (EVB/EVBU)

• MC68HC11A8
• MC68HC11E9
• MC68HC711E9
• MC68HC811E2

• The BUFFALO ROM monitor program, which resides in the on-board MC68HC11, provides one-line assembly, disassembly, and debugging commands to simplify debugging and evaluation of M68HC11 MCUs.
• Either expanded mode of operation, with full bus access for debugging and evaluation (EVB), or single-chip (I/O only) mode of operation (EVBU).
• Built-in RS-232C I/O port circuitry that supports communication and data transfers between the EVB/EVBU and the external terminal or host computer.
• In the EVBU, a wire-wrap area for MCU custom interfacing, with a hole pattern that allows installation of most DIP sockets, strip sockets, headers, and connectors. This interfacing takes advantage of the MCU I/O port connector.

System Requirements Both the EVB and the EVBU use an RS-232C I/O-compatible external terminal or a host computer running such a terminal program. For the EVBU, a +5-volt DC power supply is needed; for the EVB, the power supply must provide +5-volt DC, +12-volt DC, and –12-volt DC.

Selecting and Ordering the Right Board To order the EVB or EVBU for evaluation of one of the four M68HC11 devices for which they can be used, simply indicate the required part number:

• MC68HC11EVB – Includes one flat-ribbon cable for target use.
• MC68HC11EVBU – Contains a wire-wrap area for system development use.
