allows die temperature measurement over a range of –40 ºC to +105 ° C.
These devices also include an on-chip low voltage detect block with
user-selectable threshold.
Two full-duplex, 9-bit UARTs provide serial, asynchronous communica-
tion and support the local interconnect network (LIN) serial communica-
tions protocol. The LIN bus is a cost-efficient, single master, multiple
slave organization that supports speed up to 20 kbps. The Z8 Encore! XP
F1680 Series also support an Enhanced Serial Peripheral Interface (ESPI)
controller that provides buffered full-duplex, synchronous, character-
oriented channel, and a I
2
C Master/Slave port to allow easy incorporation
into any system.
The Z8 Encore! XP F1680 Series feature three 16-bit timers with Pulse-
Width Modulation (PWM), Capture, and Compare capabilities. The
timers can operate in Stop mode using a low-power 32 kHz peripheral
clock. The noise filter prevents false MCU wakeup, which eventually
results in long-lasting battery. The Z8 Encore! XP F1680 Series also
feature a multichannel timer that supports four Capture/Compare modules
on one timer.
The Z8 Encore! XP F1680 Series feature a user-selectable system clock
and an external 32 kHz, watch-crystal-based, low-power peripheral clock.
System clock sources include a high accuracy Internal Precision Oscilla-
tor (IPO) requiring no external components and an on-chip oscillator
using external crystal, resonator, or low-cost RC circuit. The on-chip IPO
is 2% accurate over standard temperature and voltage, and its output
frequency is selectable in the 11 MHz to 43 kHz range. A low-power
external 32 kHz, watch-crystal-based peripheral clock is available for the
operation of timers in STOP mode as well as for the implementation of a
real-time clock.
The Z8 Encore! XP F1680 Series support a single-pin debugger and
programming interface that simplifies code development and allows easy
in-circuit programming.
