The MC9S08SG8 members of the low-cost, high-performance HCS08 family of 8-bit microcontroller units (MCUs). All MCUs in the family use the enhanced HCS08 core and are available with a variety of modules, memory sizes, memory types, and package types. The high-temperature devices have been qualified to meet or exceed AEC Grade 0 requirements to allow them to operate up to 150 °C TA.
- 8-Bit HCS08 Central Processor Unit (CPU)
- 40 MHz HCS08 CPU (central processor unit)
- 36 MHz HCS08 CPU for temperatures greater than 125°C
- 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 16MHz
- 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 1.5% deviation over temperature –40 to 125°C or 3% deviation for temperature > 125°C and voltage; supports bus frequencies from 2 MHz to 20MHz.
- 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; 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 (plus 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.
- Input/Output
- 16 general purpose I/O pins (GPIOs)
- 8 interrupt pins with selectable polarity
- Ganged output option for PTB[5:2] and PTC[3:0]; allows single write to change state of multiple pins
- Hysteresis and configurable pull up device on all input pins; Configurable slew rate and drive strength on all output pins.
- Package Options
- 20-TSSOP (not available on high-temperature rated devices)
- 16-TSSOP
- 8-SOIC (not available on high-temperature rated devices)
