TBD
28 W-SOIC
Case 751F
Features:
⢠8-Bit RS08 Central Processor Unit (CPU)
â Up to 20 MHz CPU at 2.7 V to 5.5 V across temperature
range of â40°C to 85°C
â Subset of HC08 instruction set with added BGND
instructions
⢠On-Chip Memory
â 4 KB flash memory read/program/erase over full
operating voltage and temperature
â 256-byte random-access memory (RAM)
â Security circuitry to prevent unauthorized access to flash
memory contents
⢠Power-Saving Modes
â Wait and stop
⢠Clock Source Options
â Oscillator (XOSC) â Loop-control Pierce oscillator;
crystal or ceramic resonator range of 31.25 kHz to
39.0625 kHz or 1 MHz to 20 MHz
â 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 2% deviation over temperature and voltage;
supports bus frequencies up to 10 MHz
⢠System Protection
â Watchdog computer operating properly (COP) reset
with option to run from dedicated 1 kHz internal clock
source or bus clock
â Low-voltage detection with reset or interrupt
â Selectable trip points
â Illegal opcode detection with reset
â Illegal address detection with reset
â Flash memory block protection
⢠Development Support
â Single-wire background debug interface
â Breakpoint capability to allow single breakpoint setting
during in-circuit debugging
⢠Peripherals
â LCD â Up to 8 Ã 14 or 4 Ã 18 segments; compatible
with 5 V or 3 V LCD glass displays using on-chip
resistor bias network; functional in wait, stop modes for
very low power LCD operation; frontplane and
backplane pins multiplexed with GPIO functions;
selectable frontplane and backplane configurations
â ADC â 8-channel, 10-bit resolution; 2.5 μs conversion
time; automatic compare function; 1.7 mV/°C
temperature sensor; internal bandgap reference channel;
operation in stop; fully functional from 2.7 V to 5.5 V.
â TPM â Two 2-channel 16-bit timer/pulse-width
modulator (TPM) modules; selectable input capture,
output compare, or buffered edge- or center-aligned
PWM on each channel
â SCI â One serial communications interface module
with optional 13-bit break; LIN extensions
â KBI â 8-pin keyborad interrupt module
⢠Input/Output
â 26 GPIOs including 1 output-only pin and 1 input-only
pin
â Hysteresis and configurable pullup device on all input
pins; configurable slew rate and drive strength on all
output pins
⢠Package Options
â 28-pin SOIC
