Key features
• 8-Bit S08 central processor unit (CPU)
– Up to 20 MHz bus at 2.7 V to 5.5 V across
temperature range of -40 °C to 105 °C
– Supporting up to 40 interrupt/reset sources
– Supporting up to four-level nested interrupt
– On-chip memory
– Up to 16 KB flash read/program/erase over full
operating voltage and temperature
– Up to 256 byte EEPROM; 2-byte erase sector;
program and erase while executing flash
– Up to 2048 byte random-access memory (RAM)
– Flash and RAM access protection
• Power-saving modes
– One low-power stop mode; 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
• Clocks
– Oscillator (XOSC) - loop-controlled Pierce
oscillator; crystal or ceramic resonator range of
31.25 kHz to 39.0625 kHz or 4 MHz to 20 MHz
– Internal clock source (ICS) - containing a frequency
locked-loop (FLL) controlled by internal or external
reference; precision trimming of internal reference
allowing 1% deviation across temperature range of 0
°C to 70 °C and 2% deviation across the whole
operating temperature; up to 20 MHz
• System protection
– Watchdog with independent clock source
– Low-voltage detection with reset or interrupt;
selectable trip points
– Illegal opcode detection with reset
– Illegal address detection with reset
• Development support
– Single-wire background debug interface
– Breakpoint capability to allow three breakpoints
setting during in-circuit debugging
– On-chip in-circuit emulator (ICE) debug module
containing two comparators and nine trigger modes
• Peripherals
– ACMP - one analog comparator with both positive
and negative inputs; separately selectable interrupt
on rising and falling comparator output; filtering
– ADC - 12-channel, 12-bit resolution; 2.5 µs
conversion time; data buffers with optional
watermark; automatic compare function; internal
bandgap reference channel; operation in stop mode;
optional hardware trigger

module
– FTM - two flex timer modulators modules including
one 6-channel and one 2-channel ones; 16-bit
counter; each channel can be configured for input
capture, output compare, edge- or center-aligned
PWM mode
– IIC - One inter-integrated circuit module; up to 400
kbps; multi-master operation; programmable slave
address; supporting broadcast mode and 10-bit
addressing; supporting SMBUS and PMBUS

modules; full-duplex or single-wire bidirectional;
master or slave mode
– TSI - supporting up to 16 external electrodes;
configurable software or hardware scan trigger; fully
support N✖P touch sensing software library;
capability to wake MCU from stop3 mode
• Input/Output
– Up to 37 GPIOs including one output-only pin
– One 8-bit keyboard interrupt module (KBI)
