MC9RS08KA8
MC9RS08KA8 Series
Covers: MC9RS08KA8
MC9RS08KA4
Features:
⢠8-Bit RS08 Central Processor Unit (CPU)
â Up to 20 MHz CPU at 1.8 V to 5.5 V across temperature
range of â40°C to 85°C
â Subset of HC08 instruction set with added BGND
instruction
⢠On-Chip Memory
â 8 KB flash read/program/erase over full operating
voltage and temperature; KA4 has 4 KB flash
â 254 byte random-access memory (RAM); KA4 has 126
byte RAM
â Security circuitry to prevent unauthorized access to
RAM and flash contents
⢠Power-Saving Modes
â Wait and stop
â Wakeup from power-saving modes using real-time
interrupt (RTI), KBI, or ACMP
⢠Clock Source Options
â Oscillator (XOSC) â Loop-Control Pierce oscillator;
crystal or ceramic resonator range of 31.25 kHz to
39.0625 kHz or 1 MHz to 5 MHz
â Internal Clock Source (ICS) â 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
â Watchdog computer operating properly (COP) reset
with option to run from dedicated 1 kHz internal clock
source or bus clock
â Low-Voltage detection with reset or interrupt
â Illegal opcode detection with reset
â Illegal address detection with reset
â Flash block protection
⢠Development Support

â Single-Wire background debug interface
â Breakpoint capability to allow single breakpoint setting
during in-circuit debugging
⢠Peripherals
â ADC â 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)
â TPM â One 2-channel; selectable input capture, output
compare, or buffered edge- or center-aligned PWM on
each channel
â IIC â Inter-Integrated circuit bus module capable of
operation up to 100 kbps with maximum bus loading;
capable of higher baudrates with reduced loading
â MTIM1 and MTIM2 â Two 8-bit modulo timers
â KBI â Keyboard interrupts with rising or falling edge
detect; eight KBI ports in 16-pin and 20-pin packages
â ACMP â Analog comparator: full rail-to-rail supply
operation; option to compare to fixed internal bandgap
reference voltage; can operate in stop mode
⢠Input/Output
â 14/18 GPIOs including one output only pin and one
input only pin
â Hysteresis and configurable pullup device on all input
pins; configurable slew rate and drive strength on all
output pins
⢠Package Options
â 16-pin SOIC, PDIP or TSSOP
â 20-pin SOIC or PDIP
