Low Voltage and Low Power Solutions with F1680 Series Microcontrollers


Zilog's F1680 Series of Flash Microcontrollers are ideal for Low Voltage and Low Power Applications. The 1.8V to 3.6V operating range provides optimal operation from two 1.5V battery cells. These Z8 Encore! XP devices are based on the popular eZ8 CPU core and feature highly integrated analog and digital peripheral functionality optimized for the touch screen panel and motor control markets. The F1680 Series of Flash microcontrollers supports 1.8–3.6 V operation with very low Active, Halt, and Stop Mode currents and many power-saving features.


F1680 Series


Zilog’s F1680 Series devices tie together key peripherals to offer a solid solution for those looking for a device that can accommodate such features as capacitive and resistive sensing, touchscreen functionality, backlit control, panel control, and temperature compensation. Additionally, the F1680 Series incorporates a best-in-class feature set that is optimized for stepper motor/microstepping control, making it an excellent product of choice for applications that require both touch screen and step motor functionality. 



This fully integrated, single-chip solution helps simplify your overall system design, afford a better system Bill of Materials (BOM) cost, and allows a fast time-to-market advantage over competing solutions. The F1680 Series is also a full drop-in/pin-compatible replacement to any existing Z8 Encore! XP 20- or 28-pin device.
