A FLASH MCU SOLUTION

68HC908RK2

8-bit Microcontroller

TARGET APPLICATIONS

• Remote keyless entry

• Hand held battery

operated devices

FEATURES

BENEFITS

HIGH-PERFORMANCE 68HC08 CPU CORE

• 4 MHz bus operation at 3V operation for

250 nsec minimum instruction cycle time

• Object code compatible with the 68HC05

• Easy to learn and use architecture

• 2 MHz bus operation at 1.8V for 500

nsec minimum instruction cycle time

• Efficient instruction set including

multiply and divide

• 16 flexible addressing modes including

stack relative with 16-bit stack pointer

• Fully static low-voltage, low-power

design with wait and stop modes

• C optimized architecture provides

compact code

The 68HC908RK2 is optimized for

low-power operation down to 1.8V.

The 68HC908RK2 is a flexible, functional

solution that reduces operating costs

with on-chip features like an internal

oscillator that requires no external

components. The 68HC908RK2 also

includes multiple system protection

features and timers.

INTEGRATED FIRST GENERATION FLASH MEMORY

• In-application re-programmable

• Cost-effective programming changes

and field software upgrades via

in-application programmability and

re-programmability

• FLASH programming across the

68HC08’s full operating supply voltage

with no extra programming voltage

• Allows re-programmable battery

powered applications

KBI

CPU08

PORT A

• Flexible block protection and security

• Protects code from unauthorized reading

and to guard against unintentional

erasing/writing of user-programmable

segments of code

128 RAM

2K FLASH

MON

BRK

INTERNAL CLOCK GENERATOR

• Software selectable bus frequencies

• 2% accuracy with trim capability

• Clock monitor

• Option to use external clock source or

external crystal/ceramic oscillator

• Programmable internal clock eliminates

the need and cost of an external clock

source

• Accurate across temperature and

voltage

SIM

IRQ

TWO PROGRAMMABLE 16-BIT TIMER CHANNELS

TIM

ICG

PORT B

• 250 nsec resolution at 4 MHz bus

• Free-running counter or modulo up-

counter

• Each channel independently

programmable for input capture, output

compare or unbuffered PWM

• Pairing timer channels provides a

buffered PWM function

COP

LVI
