Datasheet

8-Bit HCS08 Central Processor Unit (CPU)
• 40-MHz HCS08 CPU
• HC08 instruction set with added BGND instruction
• Support for up to 32 interrupt/reset sources
Memory Options
• FLASH read/program/erase down to 1.8 V
• Up to 16K FLASH; up to 2K RAM
Power-Saving Modes
• Three very low power stop modes
• Reduced power wait mode
• Very low power real time interrupt for use in run,
wait, and stop
Clock Source Options
• Clock sources to internal hardware frequency
locked-loop (FLL): internal, external, crystal, or
resonator
• Internal clock with ±0.2% trimming resolution and
±0.5% deviation across voltage or across
temperature
System Protection
• Optional watchdog computer operating properly
(COP) reset
• Low-voltage detection with reset or interrupt
• Illegal opcode detection with reset
• Illegal address detection with reset
• FLASH block protect and security
Peripherals
• ATD — 8-channel, 10-bit analog-to-digital
converter
• SCI — Two serial communications interface
modules
• SPI — Serial peripheral interface module
• IIC — Inter-integrated circuit bus module
• Timer —One 3-channel timer PWM module (TPM)
plus one 2-channel TPM
• KBI — 8-pin keyboard interrupt module
Input/Output
• 8 high-current pins (20 mA each)
• Software selectable pullups on ports when used as
input
• Internal pullup on RESET and IRQ pin to reduce
customer system cost
• Up to 38 general-purpose input/output (I/O) pins,
plus one output-only pin, depending on package
selection
Development Support
• Background debugging system
• Breakpoint capability to allow single breakpoint
setting during in-circuit debugging (plus two more
breakpoints in on-chip debug module)
• On-chip, in-circuit emulation (ICE) debug module
with real-time bus capture. On-chip ICE debug
module containing two comparators and nine trigger
modes. Eight deep FIFO for storing change-of-flow
addresses and event-only data.
• Single-wire background debug interface
Package Options
• 48-pin QFN
• 44-pin QFP
• 42-pin PSDIP
• 32-pin QFN
