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

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

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

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

FOURTEEN BIDIRECTIONAL INPUT/OUTPUT (I/O) LINES
• High-current sink/source capability on
all I/O
• Keyboard scan with selectable
interrupts on six pins
• High-current I/O allows direct drive of
LED and other circuits to eliminate
external drivers and reduce systems
costs
• Keyboard scan with programmable
pullups eliminates external glue logic
when interfacing to simple keypads
• Software programmable pullups on six
pins
