MC9S08SH8CTGR Description
The 8-bit microcontroller architecture is simpler and has an easy to understand programming model. It usually needs just a single supply. Despite marketing claims to the contrary, modern 8-bit architectures are lower power compared to 32-bit because the innards toggle fewer bus signals.
MC9S08SH8CTGR Features
8-Bit HCS08 Central Processor Unit (CPU)
? 40-MHz HCS08 CPU (central processor unit)
? HC08 instruction set with added BGND instruction
? Support for up to 32 interrupt/reset sources
On-Chip Memory
? FLASH read/program/erase over full operating
voltage and temperature
? Random-access memory (RAM)
Power-Saving Modes
? Two 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
? Oscillator (XOSC) — Loop-control Pierce
oscillator; Crystal or ceramic resonator range of
31.25 kHz to 38.4 kHz or 1 MHz to 16 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 from 2 MHz to 20 MHz.
System Protection
? Watchdog computer operating properly (COP)
reset with opti/n to run from dedicated 1-kHz
internal clock source or bus clock
? Low-voltage detection with reset or interrupt;
selectable trip points
? Illegal opcode detection with reset
? Illegal address detection with reset
? FLASH block protect
Development Support
? Single-wire background debug interface
? Breakpoint capability to allow single breakpoint
setting during in-circuit debugging (pluss two
more breakpoints in on-chip debug module)
? On-chip, in-circuit emulation (ICE) debug module
containing two comparators and nine trigger
modes. Eight deep FIFO for storing
change-of-flow address and event-only data.
Debug module supports both tag and force
breakpoints.
MC9S08SH8CTGR Applications
These features make the STM32F105xx and STM32F107xx connectivity line microcontroller family suitable for a wide range of applications such as motor drives and application control, medical and handheld equipment, industrial applications.
