MC9S08QE128
8-Bit HCS08 Central Processor Unit (CPU)
– Up to 50.33-MHz HCS08 CPU above 2.4V, 40-MHz
CPU above 2.1V, and 20-MHz CPU above 1.8V, across
temperature range
– 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)
– Security circuitry to prevent unauthorized access to
RAM and flash contents
Power-Saving Modes
– Two low power stop modes; reduced power wait mode
– Peripheral clock enable register can disable clocks to
unused modules, reducing currents; allows clocks to
remain enabled to specific peripherals in stop3 mode
– Very low power external oscillator can be used in stop3
mode to provide accurate clock to active peripherals
– Very low power real time counter for use in run, wait,
and stop modes with internal and external clock sources
–6
μs typical wake up time from stop modes
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) — FLL controlled by
internal or external reference; precision trimming of
internal reference allows 0.2% resolution and 2%
deviation; supports CPU freq. from 2 to 50.33 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
– Flash block protection
Development Support
– Single-wire background debug interface
– Breakpoint capability to allow single breakpoint setting
during in-circuit debugging (plus two more breakpoints)
– On-chip in-circuit emulator (ICE) debug module
containing two comparators and nine trigger modes.
Eight deep FIFO for storing change-of-flow addresses
and event-only data. Debug module supports both tag
and force breakpoints.
ADC — 24-channel, 12-bit resolution; 2.5
μs conversion
time; automatic compare function; 1.7 mV/
°C temperature
sensor; internal bandgap reference channel; operation in
stop3; fully functional from 3.6V to 1.8V
ACMPx — Two analog comparators with selectable
interrupt on rising, falling, or either edge of comparator
output; compare option to fixed internal bandgap reference
voltage; outputs can be optionally routed to TPM module;
operation in stop3
SCIx — Two SCIs with full duplex non-return to zero
(NRZ); LIN master extended break generation; LIN slave
extended break detection; wake up on active edge
SPIx— Two serial peripheral interfaces with Full-duplex or
single-wire bidirectional; Double-buffered transmit and
receive; MSB-first or LSB-first shifting
IICx — Two IICs with; 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
TPMx — One 6-channel and two 3-channel; Selectable
input capture, output compare, or buffered edge- or
center-aligned PWMs on each channel
RTC — 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
Input/Output
– 70 GPIOs and 1 input-only and 1 output-only pin
– 16 KBI interrupts with selectable polarity
– Hysteresis and configurable pull-up device on all input
pins; Configurable slew rate and drive strength on all
output pins.
– SET/CLR registers on 16 pins (PTC and PTE)
