S9S08RNA16W2MLC 8-bit Microcontrollers – MCU 8-bit MCU, S08 core, 16KB Flash, 20MHz, -40/+125degC, Automotive Qualified, QFP 32

• 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 125 °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 with ECC; 2-byte erase sector; EEPROM program and erase while executing code from 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

– 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 -40 °C to 85 °C, 1.5% deviation across temperature range of -40 °C to 105 °C, and 2% deviation across temperature range of -40 °C to 125 °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
