Motion-control MCU responds at touch of a virtual button

The Zilog Z8 Encore! XP® F1680 MCU family combines the Zilog EZ8™ CPU core with peripherals for touch-screen and motor-control applications.

In addition to its peripheral set, the F1680 series incorporates best-in-class stepper-motor control techniques for functions including micro-stepping. This delivers performance advantages in addition to higher integration and board-space savings in products requiring both touch-screen and stepmotor functionality. The performance of the EZ8 CPU core also benefits motor-control applications, with 10MIPS capability allowing rapid execution of motor-control algorithms.

The touch-sensor peripherals allow designers to easily implement resistive or capacitive sensing, touch-screen functionality, backlight controls and temperature compensation.

Complementing its motor-control capabilities, the F1680 series also implements an on-chip temperature sensor that enables designers to measure the die temperature to within ±7°C over the full operating range from -40°C to 105°C. Within the range 20°C to 30°C, the reading is accurate to ±1.5°C.
