40-MHz HCS08 CPU (central processor unit)
20-MHz internal bus frequency
HC08 instruction set with added BGND
instruction
Background debugging system
Breakpoint capability to allow single breakpoint
setting during in-circuit debugging (plus two
more breakpoints in on-chip debug module)
Debug module containing two comparators and
nine trigger modes. Eight deep FIFO for storing
change-of-ow addresses and event-only data.
Debug module supports both tag and force
breakpoints.

Memory Options
Up to 16 KB of on-chip in-circuit programmable
FLASH memory with block protection and
security options
Up to 1 KB of on-chip RAM
Clock Source Options
Clock source options include crystal, resonator,
external clock, or internally generated clock
with precision NVM trimming
System Protection
Optional computer operating properly (COP)
reset with option to run from independent
internal clock source or bus clock
Low-voltage detection with reset or interrupt
Illegal opcode detection with reset

Wait plus two stops
Peripherals
ADC — 8-channel, 10-bit analog-to-digital
converter with automatic compare function
SCI — Two serial communications interface
modules with optional 13-bit break
SPI — Serial peripheral interface module
IIC — Inter-integrated circuit bus module to
operate at up to 100 kbps with maximum bus
loading; capable of higher baud rates with
reduced loading
Timers — Three1 16-bit timer/pulse-width
modulator (TPM) modules — Two
1 2-channel
and one 4-channel; each has selectable input
capture, output compare, and edge-aligned
PWM capability on each channel. Each timer
module may be congured for buffered,
centered PWM (CPWM) on all channels
KBI — 7-pin keyboard interrupt module
Input/Output
Up to 38 general-purpose input/output (I/O)
pins
Software selectable pullups on ports when
used as inputs
Software selectable slew rate control on ports
when used as outputs
Software selectable drive strength on ports
when used as outputs
Master reset pin and power-on reset (POR)
Internal pullup on RESET, IRQ, and BKGD/MS
pins to reduce customer system cost
Package Options
48-pin quad at no-lead package (QFN)
44-pin low-prole quad at package (LQFP)
32-pin low-prole quad at package (LQFP)
