The S08LL 8-bit segment LCD microcontroller family is ideal for battery-powered applications such as medical diagnostics or handheld appliances. The S08LL family extends battery life with industry leading low-power technology, speeds development time and eliminates excess cost with its complete tower ecosystem.
S08 Central Processor Unit (CPU)
- Up to 40 Mhz CPI at 3.6V to 2.1V
- Up to 20 MHz CPU at 2.1V to 1.8V across temperature range of -40°C to +85°C
- HCS08 instruction set with added BGND instruction
Enablement and Development Support
- Low-cost, reconfigurable Tower evaluation and demonstration platform
- Breakpoint capability
- ICE debug module
- three comparators and nine trigger modes
- Eight deep FIFO for storing change-of-flow addresses and event-only data
- supports both tag and force breakpoints.
- Migration path from smaller flash size devices (LL16)
Power-Saving Features
- Two ultra-low-power stop modes, one of which allows limited use of peripherals
