Development Tools

M68HC05 Family

The M68HC05 Family is supported by a variety of

development tools including Evaluation Modules (EVM) and

Evaluation Systems (EVS). Both provide an economical

means of designing, debugging, and evaluating M68HC05

microcontrollers in a target system environment.

Many new M68HC05 CSIC devices are supported by an

MCU–specific EVS. The EVS is a two–board system

consisting of a 68HC05 Platform Board (PFB) and an

Emulator Module (EM) which contains the emulating

microcontroller, and control circuits.

The M68HC05 Family is also supported by the Compact

Development System (CDS) for 8–bit microcontrollers

(M68CDS8HC05),

powerful,

portable,

full–featured

emulator for debugging hardware and software operations.

The

CDS8HC05

features

high–speed,

non–invasive,

in–circuit emulation with real–time trace, and a powerful bus

state analyzer. Commands are entered from an MS–DOS

host computer.

The Motorola Modular Development System for the

M68HC05 Family, MMDS05, allows the use of Emulation

Modules (EM) that are compatible with the existing EVS

product line. The MMDS05 provides an upgrade for

CDS8HC05 customers. The MMDS05 has all of the features

of the CDS8HC05, and includes a notable enhancement. A

dual–port RAM “memory window” allows a user to to modify

memory while a program is running at full speed. An internal

power

supply

and

totally

shielded

enclosure

assure

compliance

with

FCC

and

EC92

regulations.

The

development software provided with the MMDS05 is an

enhancement of the EVM05/EVM11 front end — it provides an

integrated development environment with true Source Level

Debug (SLD).

M68HC11 Family

The M68HC11 Family is supported by a variety of

economical development tools. These include Evaluation

Boards (EVB), Evaluation Modules (EVM), and Evaluation

Systems (EVS).

An EVB allows a user to debug code under the BUFFALO

(Bit

Operations)

monitor/debugging program contained in the microcontroller

ROM. The EVB emulates only the single–chip mode of

operation and has no EPROM programmer. The EVBU, a

“universal” version of the EVB, includes a wire–wrap area for

custom interfacing.

EVM are low–cost tools for designing, debugging, and

evaluating M68HC11 devices in a target system. An EVM

provides essential microcontroller signals and timing, and

on–board monitor/debugging firmware contains extensive

commands for controlling I/O and debug operations.

An EVS is a two–board system consisting of a 68HC11

Platform Board (PFB) and an Emulator Module (EM). The EM

contains control circuits and a 68HC11 MCU for the part or

series of parts being emulated. An EVS provides expanded,

multiplexed, special test, and single–chip mode emulation, a

dual 64 kbyte memory map with 64 kbytes of emulation RAM,

and an RS–232 port.

In addition, the Intermetrics Whitesmiths 68HC11 C

Compiler/Assembler (M68S11CCAB) and 68HC11 Simulator

Debugger (M68S11SIMAB) are now available through

Motorola.

Modular Microcontroller

Families

In–circuit debuggers for modular microcontroller families

(M68ICD32 and M68ICD16) are economical development

and debugging environments. ICD make use of the

non–intrusive Background Debug Mode (BDM) interface, and

provide sophisticated software debugging functions. The ICD

consist of debugger and assembler development software, a

small interconnect board, and target system cable. The

IASM32

and

IASM16

assemblers

provide

single

development environment that includes an editor and

cross–assembler programs. ICD source–level debugger

software uses easy–to–read screen windows to display

breakpoints, program memory, and data memory.

The MC68331 and MC68332 are supported by evaluation

kits (EVK). These multi–board systems include a common

platform board, a Business Card Computer (BCC) that

contains the MCU being emulated, and the CPU32BUG

debug monitor program. The EVK is a cost–effective system

for designing, debugging, and evaluating target system

software and hardware. The MC68340 is supported by an

evaluation system (EVS) similar to the EVK with the addition

of a development interface board for a comprehensive

development environment.

The

Evaluation

Board

(EVB)

inexpensive tool for designing, debugging, and evaluating the

MC68HC16Z1.

Features

include

background–mode

operation,

integrated

assembly/editing/emulation

environment, and logic analyzer pod connectors.

Modular evaluation boards (MEVB) for each modular

family member are under development. The MEVB system is

a multi–board evaluation system that consists of a common

platform board (PFB) and interchangeable MCU personality

boards (MPB). The MEVB system provides an economical

development environment for downloading and debugging

software generated with IASM16 and IASM32.

Motorola also sells the Intermetrics Whitesmiths 68HC16

Compiler/Assembler

(M68S16CCAB)

and

68HC16

Simulator Debugger (M68S16SIMAB) for the M68HC16

Family. In addition, the Intermetrics InterTools

™ 683XX C

Compiler/Assembler (M68S32CCAB) and 683XX ROM

Monitor Debugger (M68S32ROMAB) for the M68300 Family

are now available through Motorola.
