Z8 Encore! 8-Bit Microcontrollers


Zilog’s Z8 Encore! XP® Flash Microcontrollers integrate numerous functionalities for intelligent battery charging applications. Add the free development tool suite of ZDSII and you have a complete embedded control solution. Z8 Encore! XP® provides adaptive charging with automatic switch over from a constant current charge to a constant voltage mechanism and delta-V or peak-V termination methods. This is controlled by a feedback loop using the PWM output of the 16-bit multi-mode timer and the high resolution Sigma/Delta ADC, which continuously monitors both the output voltage and current of the DC-DC converter and battery current.


The Z8 Encore! XP® can perform additional tasks, such as communication, control, status/event logging and system monitoring. The extra PWM can be used to drive a DC motor with over-current protection provided by the on-chip comparator. Interface to external sensors with the high resolution Sigma/Delta ADC (which support differential inputs and chopping). Use the 8-pin device for dedicated battery charging applications or select from SOIC and SSOP 8/ 20 or 28-pin packages to optimize your design.
