Freescale introduces the first RS08 cost-effective MCUs with LCD drivers. The highly integrated but extremely low-cost 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 functionality.
Features
- Up to 10 MHz (bus frequency) RS08 CPU at 1.8 volts for 100 ns minimum instruction time
- Configurable display for 8 x 14 or 4 x 18 segment display
- LCD driver pins are muxed with GPIO and other functions
- Up to 4 KB flash read/program/erase over full operating voltage and temperature
- 8-channel,10-bit resolution analog-to-digital converter (ADC)— 2.5 µs conversion time
- Timer— two 2-channel selectable input capture.
- Serial communications interface (SCI) 26 general purpose input/output (GPIO), one output-only pin and one input-only pin
- Watchdog computer operating properly (COP)
- Low-voltage detection with reset or interrupt; selectable trip points
- Single-wire background debug interface
