Case 948F
Features
• 8-Bit S08 Central Processor Unit (CPU)
– Up to 40 MHz CPU at 2.7 V to 5.5 V across temperature
range of –40 °C to 125 °C
– HC08 instruction set with added BGND instruction
– Support for up to 32 interrupt/reset sources
• On-Chip Memory
– 4 KB flash read/program/erase over full operating
voltage and temperature
– 128-byte 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
– Allows clocks to remain enabled to specific peripherals
in stop3 mode
• Clock Source Options
– 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 1% deviation over 0–70 °C and voltage, 2%
deviation over –40–85 °C and voltage, or 3% deviation
over –40–125 °C and voltage; supporting bus
frequencies up 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 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
• Peripherals
– IPC — Prioritize interrupt sources besides inherent
CPU interrupt table; support up to 32 interrupt sources
and up to 4-level preemptive interrupt nesting
– ADC — 8-channel, 10-bit resolution; 2.5 μs conversion
time; automatic compare function; temperature sensor;
internal bandgap reference channel; operation in stop;
fully functional from 2.7 V to 5.5 V
– TPM — One 40 MHz 6-channel and one 40 MHz
1-channel timer/pulse-width modulators (TPM)
modules; selectable input capture, output compare, or
buffered edge- or center-aligned PWM on each channel
– MTIM16 — Two 16-bit modulo timers
– PWT — Two 16-bit pulse width timers (PWT);
selectable driving clock, positive/negative/period
capture
– PRACMP — Two programmable reference analog
comparators with eight optional inputs for both positive
and negative inputs; 32-level internal reference voltages
scaled by selectable reference inputs
– IIC — Inter-integrated circuit bus module capable of
operation 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
– KBI — 4-pin keyboard interrupt module with software
selectable polarity on edge or edge/level modes
– FDS — Shut down output pin upon fault detection; the
fault sources can be optional enabled separately; the
output pin can be configured as output 1,0 and high
impedance when a fault occurs based on module
configuration
• Input/Output
– 18 GPIOs including one input-only pin and one
output-only pin
– Hysteresis and configurable pullup device on all input
pins; schmitt trigger on PWT input pins; configurable
slew rate and drive strength on all output pins.
• Package Options
– 16-pin TSSOP
– 20-pin TSSOP
