Zilog's Z8F1680 Series of Flash Microcontrollers are ideal for low voltage and low power applications. The 1.8 V to 3.6V operating range provides optimal operation from two 1. 5V battery cells.
For common low power applications in which the Microcontroller (MCU ) is normally in STOP Mode and periodically wakes up to determine if any actions must be taken, the Z8F1680 series provides low Stop mode current and multiple wake up methods. The Watch Dog Timer (WDT), General Purpose I/Os (GPIO), Comparator and dedicated 32-KHz timer can all be used to wake the device from Stop mode. Additionally, 1 KB of the devices RAM can be assigned as Low Power Program RAM for execution, so power is conserved even in Active (Run) modes.
Wake uptime from Stop mode is 6µS (maximum, worst case, extended temperature), so very little power is wasted as the device comes out of Stop mode.
The 10-bit SAR ADC combined with the 4-channel 16-bit PWM timer array provides support for multicell battery charging applications and multi-phase motor control.
By taking advantage of the on-chip temperature sensor, Op Amp, ADC, and independent programmability of each PWM channel, this timer array also becomes an ideal RGBW LED controller.
As part of the Z8 Encore! XP® family, the Z8F1680 series is pin for pin compatible with Z8F082A, Z8F0830, and Z8F083A series, features a single-pin, on-chip debugger (OCD), and is supported by Zilog Developer Studio (ZDS-II) Integrated Development Environment.
With its extended, intelligent peripheral set and significant power savings, the Z8F1680 Series adds even more design flexibility and choice for many low voltage and low power applications.
