64-LQFP
Case 840F
80-LQFP
Case 917A
8-Bit HCS08 Central Processor Unit (CPU)
– Up to 40 MHz CPU at 3.6 V to 2.1 V across temperature
range of –40 °C to 85 °C
– Up to 20 MHz at 2.1 V to 1.8 V across temperature range
of –40 °C to 85 °C
– HC08 instruction set with added BGND instruction
– Support for up to 32 interrupt/reset sources
On-Chip Memory
– Dual array 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
– Low-power run and wait modes allow peripherals to run
while voltage regulator is in standby
– Peripheral clock gating register can disable clocks to
unused modules, thereby reducing currents
– Very low-power external oscillator that can be used in
stop2 or stop3 modes to provide accurate clock source to
time-of-day (TOD) module
–6
μs typical wakeup time from stop3 mode
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; supporting
bus frequencies from 1 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 warning with interrupt
– Low-voltage detection with reset or interrupt
– Illegal opcode detection with reset; illegal address
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 in
on-chip debug module)
– On-chip in-circuit emulator (ICE) debug module
containing three comparators and nine trigger modes
Peripherals
– LCD — Up to 8
×36 or 4×40 LCD driver with internal
charge pump and option to provide an
internally-regulated LCD reference that can be trimmed
for contrast control
– ADC —10-channel, 12-bit resolution; up to 2.5
μs
conversion time; automatic compare function;
temperature sensor; operation in stop3; fully functional
from 3.6 V to 1.8 V
– IIC — Inter-integrated circuit bus module to operate at up
to 100 kbps with maximum bus loading; multi-master
operation; programmable slave address; interrupt-driven
byte-by-byte data transfer; broadcast mode; 10-bit
addressing
– ACMP — Analog comparator with selectable interrupt on
rising, falling, or either edge of comparator output;
compare option to fixed internal reference voltage;
outputs can be optionally routed to TPM module;
operation in stop3
– SCIx — Two full-duplex non-return to zero (NRZ)
modules (SCI1 and SCI2); LIN master extended break
generation; LIN slave extended break detection; wakeup
on active edge
–SPI — Full-duplex or single-wire bidirectional;
double-buffered transmit and receive; master or slave
mode; MSB-first or LSB-first shifting
– TPMx — Two 2-channel (TPM1 and TPM2); selectable
input capture, output compare, or buffered edge- or
center-aligned PWM on each channel
– TOD — (Time-of-day) 8-bit, quarter second counter with
match register; external clock source for precise time
base, time-of-day, calendar, or task scheduling functions
– VREFx — Trimmable via an 8-bit register in 0.5 mV
steps; automatically loaded with room temperature value
upon reset; can be enabled to operate in stop3 mode;
trim register is not available in stop modes.
Input/Output
– Dedicated accurate voltage reference output pin, 1.15 V
output (VREFOx); trimmable with 0.5 mV resolution
– Up to 39 GPIOs, two output-only pins
– Hysteresis and configurable pullup device on all input
pins; configurable slew rate and drive strength on all
output pins
Package Options
– 14mm
× 14mm 80-pin LQFP, 10 mm × 10 mm 64-pin
