Thermostat Reference Design

MC9S08LL16 Series Covers: MC9S08LL16 and MC9S08LL8

Features

• 8-Bit HCS08 Central Processor Unit (CPU)

– Up to 20-MHz CPU at 3.6V to 1.8V across temperature range of -40°C to 85°C

– HC08 instruction set with added BGND instruction

– Support for up to 32 interrupt/reset sources

• On-Chip Memory

– Dual Array FLASH read/program/erase over full operating voltage and temperature

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

– Low power run and wait modes allow peripherals to run while voltage regulator is in standby

– Peripheral clock gating register can disable clocks to unused modules, thereby reducing currents.

– Very low power external oscillator that can be used in stop2 or stop3 modes to provide accurate clock source to real time counter
