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
