125 nsec minimum instruction cycle time

• Object code compatible with the 68HC05

• Easy to learn and use architecture

• Appliance compressors

• Smart appliances

• Efficient instruction set including multiply

and divide

• C optimized architecture provides compact

code

• Industrial compressors (HVAC)

• Variable speed pumps (well, gas)

• HVAC blowers and fans

• General purpose drives

• Exercise equipment

• 16 flexible addressing modes including

stack relative with 16-bit stack pointer

INTEGRATED SECOND GENERATION FLASH MEMORY

• In-application re-programmable

• Extremely fast programming, encoding

64 bytes in as fast as 2 msec

• Cost-effective programming changes and

field software upgrades via in-application

programmability and re-programmability

• Seat module control

• Uninterruptible power supplies

• Reduces production programming costs

through ultra-fast programming

• Byte-writable for data as well as program

memory

• Protects code from unauthorized reading

and to guard against unintentional

erasing/writing of user-programmable

segments of code

• FLASH programming across the 68HC08’s

full operating supply voltage with no extra

programming voltage

• 10K write/erase cycles minimum over

temperature

• Flexible block protection and security

The 68HC908MR8 improves design

capabilities for 3-phase, variable speed

motion control. Each device incorporates

the fault tolerant and flexible 6-channel,

12-bit Pulse Width Modulator, supporting

center and edge-aligned modes with

automatic dead-time insertion and

patented dead-time compensation

capability. The 68HC908MR8 is designed

to save money and space, and includes

powerful features like 8K of FLASH

memory, a 10-bit analog-to-digital

converter (ADC), an asynchronous serial

communications interface (SCI) and small

outline packages.

10-BIT ANALOG-TO-DIGITAL CONVERTER

• 7 channels

• Provides single or continuous conversion

• Single conversion in 17 µsec

• Generates an interrupt when input signal

exceeds a software programmable limit

12-BIT PULSE WIDTH MODULATION FOR MOTOR CONTROL

• 3 complementary or 6 independent PWM

signals

• Provides multiple motor or multi-phase

control capability

• Programmable output polarity

• Edge- or center-aligned waveforms

• Reduces system cost through integration of

digital/analog circuitry

• Drastically reduces system-noise and

improves efficiency of the drive without the

need for external current sensors with

patented dead-time compensation

• Allows direct drive of the opto-coupling

stage

• Automatic dead-time

generation/compensation

• 20 mA sink on all PWMMC pins

• Programmable fault detection

7-CHANNEL/

10-BIT ADC

CPU08

PORT A

256/192

RAM

• Guarantees immediate shutdown of the

PWM outputs ensuring motor and

consumer safety

8K FLASH

4K ROM

CLOCK GENERATION MODULE WITH PLL

MON

SIM

PORT C

PORT B

• Programmable clock frequency in integer

multiples of external crystal reference

• Provides high performance using low-cost,

low-frequency reference crystals

TIMA

TIMB

• Crystal reference of 1 MHz to 8 MHz

• External clock option with or without PLL

• Reduces generated noise while still

providing high performance (up to 32 MHz

internal clock)

IRQ

COP

LVI

SCI

FOUR PROGRAMMABLE 16-BIT TIMER CHANNELS

• 125 nsec resolution at 8 MHz bus

• External clock input pin

• Configurable for input capture, output
