MC9RS08KA8 Features
8-Bit RS08 Central Processor Unit (CPU)
• Up to 20 MHz CPU at 1.8 V to 5.5 V across
temperature range of –40°C to 85°C
• Subset of HC08 instruction set with added
BGND instruction
On-Chip Memory
• 8 KB flash read/program/erase over full
operating voltage and temperature
— KA4 has 4 KB flash
• 254 byte random-access memory (RAM)
— KA4 has 126 byte RAM
• Security circuitry to prevent unauthorized
access to RAM and flash contents
Power-Saving Modes
• Wait and stop
• Wakeup from power-saving modes using
real-time interrupt (RTI), KBI, or ACMP
Clock Source Options
• Oscillator (XOSC) — Loop-Control Pierce
oscillator; crystal or ceramic resonator
range of 31.25 kHz to 39.0625 kHz or
1 MHz to 5 MHz
• Internal Clock Source (ICS) — Internal
clock source module containing a
frequency-locked-loop (FLL) controlled by
internal or external reference; precision
trimming of internal reference allows 0.2%
resolution and 2% deviation over
temperature and voltage; supports bus
frequencies up to 10 MHz
System Protection
• Watchdog computer operating properly
(COP) reset with option to run from
dedicated 1 kHz internal clock source or
bus clock
• Low-Voltage detection with reset or
interrupt
• Illegal opcode detection with reset
• Illegal address detection with reset
• Flash-Block protection
Development Support
• Single-Wire background debug interface
• Breakpoint capability to allow single
breakpoint setting during in-circuit
debugging
Peripherals
• ADC — 12-channel, 10-bit resolution;
2.5 μs conversion time; automatic compare
function; operation in stop; fully functional
from 2.7 V to 5.5 V (8-channels available
on 16-pin package)
• TPM — One 2-channel; selectable input
capture, output compare, or buffered edge-
or center-aligned PWM on each channel
• IIC — Inter-Integrated circuit bus module
capable of operation up to 100 kbps with
maximum bus loading; capable of higher
baudrates with reduced loading
• MTIM1 and MTIM2 — Two 8-bit modulo
timers
• KBI — Keyboard interrupts with rising or
falling edge detect; eight KBI ports in
16-pin and 20-pin packages
• ACMP — Analog comparator; full
rail-to-rail supply operation; option to
compare to fixed internal bandgap
reference voltage; can operate in stop mode
Input/Output
• 14/18 GPIOs including one output only pin
and one input only pin
• Hysteresis and configurable pullup device
on all input pins; configurable slew rate and
drive strength on all output pins
Package Options
• 16-pin SOIC, PDIP or TSSOP
• 20-pin SOIC or PDIP
