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 60 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 4096 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 temperature

range of -40 °C to 105 °C; 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 - 16-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

– CRC - programmable cyclic redundancy check

module

– FTM - three flex timer modulators modules

including one 6-channel and two 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

– MTIM - Two modulo timers with 8-bit prescaler

and overflow interrupt

– RTC - 16-bit real timer counter (RTC)

– SCI - three serial communication interface (SCI/

UART) modules optional 13-bit break; full

duplex non-return to zero (NRZ); LIN extension

support

– SPI - one 8-bit and one 16-bit serial peripheral

interface (SPI) modules; full-duplex or single-wire

bidirectional; master or slave mode

? Input/Output

– 57 GPIOs including one output-only pin

– Two 8-bit keyboard interrupt modules (KBI)

– Two true open-drain output pins

– Eight, ultra-high current sink pins supporting 20 mA source/sink current

? Package options

– 64-pin LQFP; 64-pin QFP

– 48-pin LQFP

– 44-pin LQFP

– 32-pin LQFP
