RS08LE|8-bit with LCD Driver LE MCUs

Overview

Our RS08 microcontrollers (MCUs) with LCD drivers are highly integrated but extremely cost-effective. The MC9RS08LA8 and MC9RS08LE4 MCUs are intended for small appliances, medical equipment and other industrial and multi-market applications. The LA and LE families provide design flexibility with a large segment-based (8x mode) driver and an integrated charge pump to provide true system-on-chip (SoC) functionality.

Features

8-bit RS08 Central Processor Unit (CPU)

Up to 10 MHz (bus frequency) RS08 CPU at 2.7V for 100 ns minimum instruction time
Subset of HCS08 instruction set with added BGND instruction

LCD Driver and Internal Charge Pump

Integrated LCD driver supports both standard 3V and 5V LCD glass
Configurable display for 8 x 14 or 4 x 18 segment display
Capable of running in STOP mode
Front plane (FP) and black plane (BP) re-assignments
LCD driver pins are muxed with GPIO and other functions

On-Chip Memory

Up to 4 KB flash over full operating voltage and temperature
2.7V to 5.5V RAM
