MC9S08SG32 Series Features
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 from â40 up to 150 °C
⢠Random-access memory (RAM)
⢠Security circuitry to prevent unauthorized access
to RAM and FLASH contents
Power-Saving Modes
⢠Two very low power stop modes
⢠Reduced power wait mode
⢠Very low power real time counter for use in run,
wait, and stop
Clock Source Options
⢠Oscillator (XOSC) â 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) â 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 â40 to 125 °C
⢠3% deviation for temperature > 125 °C
⢠ICS supports bus frequencies from 2 MHz to
20 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;
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 9 trigger modes.
Eight-deep FIFO for storing change-of-ï¬ow
address and event-only data. Debug module
supports both tag and force breakpoints
Peripherals
⢠ADC â 16-channel, 10-bit resolution, 2.5 μs
conversion time, automatic compare function,
temperature sensor, internal bandgap reference
channel; runs in stop3
⢠ACMP â Analog comparators with selectable
interrupt on rising, falling, or either edge of
comparator output; compare option to ï¬xed
internal bandgap reference voltage; output can be
optionally routed to TPM module; runs in stop3
⢠SCI â Full duplex non-return to zero (NRZ); LIN
master extended break generation; LIN slave
extended break detection; wake up on active edge
⢠SPI â Full-duplex or single-wire bidirectional;
Double-buffered transmit and receive; Master or
Slave mode; MSB-ï¬rst or LSB-ï¬rst shifting
⢠IIC â Up to 100 kbps with maximum bus loading;
Multi-master operation; Programmable slave
address; Interrupt driven byte-by-byte data
transfer; supports broadcast mode and 10-bit
addressing
⢠MTIM â 8-bit modulo counter with 8-bit prescaler
and overï¬ow interrupt
⢠TPMx â Two 2-channel timer pwm modules
(TPM1, TPM2); Selectable input capture, output
compare, or buffered edge- or center-aligned
PWM on each channel
⢠RTC â (Real-time counter) 8-bit modulus counter
with binary or decimal based prescaler; External
clock source for precise time base, time-of-day,
calendar or task scheduling functions; Free
running on-chip low power oscillator (1 kHz) for
cyclic wake-up without external components, runs
in all MCU modes
Input/Output
⢠22 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 conï¬gurable pull up device on all
input pins; Conï¬gurable slew rate and drive
strength on all output pins
Package Options
⢠28-TSSOP, 20-TSSOP, 16-TSSOP (20-pin
package options not available on high-temperature
rated devices).
