A FLASH MCU SOLUTION

68HC908AB32

8-bit Microcontroller

TARGET APPLICATIONS

FEATURES

BENEFITS

• Appliances

• Data loggers

• Industrial equipment

• Automotive body electronics

HIGH-PERFORMANCE 68HC08 CPU CORE

• 8 MHz bus operation at 5V operation for

125 nsec minimum instruction cycle time

• Object code compatible with the 68HC05

• Easy to learn and use architecture

• Efficient instruction set including multiply

and divide

• C optimized architecture provides

compact code

• 16 flexible addressing modes including stack

relative with 16-bit stack pointer

• Fully static low-voltage, low-power design

with wait and stop modes

The 68HC908AB32 FLASH microcontroller

utilizes Motorola’s highly successful 68HC08

architecture and is code compatible with

68HC05 microcontrollers providing an efficient

migration path to higher performance FLASH

MCUs. With 32,256 bytes of in-system,

programmable FLASH memory and in-circuit

programming capability, the 68HC908AB32

delivers high-performance while lowering

costs. The 68HC908AB32 provides security

and reliability with innovative features like a

computer operating properly (COP) watchdog,

selectable FLASH security, memory-mapped

input/output registers, low-voltage inhibit

(LVI) and stop and wait modes.

INTEGRATED SECOND GENERATION FLASH MEMORY

• In-application re-programmable

• Extremely fast programming, encoding

64 bytes in as fast as 2 msec

• FLASH programming across the 68HC08’s

full operating supply voltage with no extra

programming voltage

• 10K write/erase cycles minimum over

temperature

• Cost-effective programming changes and

field software upgrades via in-application

programmability and re-programmability

• Reduces production programming costs

through ultra-fast programming

• Allows re-programmable battery-powered

applications

• 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

• Flexible block protection and security

INTEGRATED EEPROM

• Byte erasable

32K Flash

8-BIT ANALOG-TO-DIGITAL CONVERTER

8-ch 8-bit

ADC

• 8 channels

• Single conversion in 17 µsec

• Fast, easy conversion from analog inputs like

temperature, pressure, and fluid levels to

digital values for CPU processing

SCI

SPI

1K RAM

CLOCK GENERATION MODULE WITH PLL

• Programmable clock frequency in integer

multiples of external crystal reference

• Provides high performance using low-cost,

low-frequency reference crystals

512 EEPROM

• 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)

4-ch + 4-ch

16-bit Timer

COP

LVI

8 PROGRAMMABLE 16-BIT TIMER CHANNELS

51 GPIO

• 125 nsec resolution at 8 MHz bus

• Each channel independently programmable

for input capture, output compare or

unbuffered PWM

• Free-running counter or modulo up-counter

• Pairing timer channels provides a buffered

PWM function
