S08LL|Segment LCD LL MCUs

Overview

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.

Features

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
