Datasheet

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.
Peripherals
• ADC — 12-channel, 10-bit resolution, 2.5 μs
conversion time, automatic compare function,
temperature sensor, internal bandgap reference
channel; runs in stop3
• ACMP — Analog comparator with selectable
interrupt on rising, falling, or either edge of
comparator output; compare option to fixed
internal bandgap reference voltage; output can be
optionally routed to TPM module; runs in stop3
• SCI — Full duplex non-return to zero (NRZ); LIN
master extended break generation; LIN slave
extended break detection; wake up 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
• IIC — 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 — 8-bit modulo counter with 8-bit prescaler
and overflow interrupt
• TPMx — Two 2-channel timer pwm modules
(TPM1, TPM2); Selectable input capture, output
compare, or buffered edge- or center-aligned
PWM on each channel
• RTC — (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
• 17 general purpose I/O pins (GPIOs) and 1
output-only pin
• 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
• 24-QFN, 20-TSSOP, 20-SOIC, 20-PDIP,
16-TSSOP, 8-SOIC
