I2C

Z8FMC16100 Series Flash MCU

Product Specification

I2C

The inter-integrated circuit (I2C) controller makes the Z8 Encore! compatible with the I2C

protocol. The I2C controller consists of two bidirectional bus lines, a serial data (SDA)

line and a serial clock (SCL) line. The I2C can operate as a master and/or slave and sup-

ports multimaster bus arbitration.

Internal Precision Oscillator

The Internal Precision Oscillator (IPO) provides a stable, accurate time base without the

requirement for external components. This can reduce system cost in many applications

by eliminating the requirement for external crystals or ceramic resonators. IPO frequency

is 5.5296MHz.

Crystal Oscillator

The on-chip crystal oscillator features programmable gain to support crystals and ceramic

resonators from 32KHz to 20MHz. The oscillator can also be used with clock drivers.

Standard Timer

The 16-bit reloadable timer can be used for timing/counting events and PWM signal gen-

eration. This timer provides a 16-bit programmable reload counter and operate in One-

Shot, Continuous, Gated, Capture, Compare, Capture and Compare, and PWM modes.

This timer can measure velocity from a tachometer wheel or read sensor outputs for rotor

position for brushless DC motor commutation. The standard timer can also be used for

general purpose timing and counting operations.

Interrupt Controller

The Z8FMC16100 Series Flash MCU products support 3 levels of programmable interrupt

priority. The interrupt sources include internal peripherals, general-purpose I/O pins, and

system fault detection.

Reset Controller

The Z8FMC16100 Series Flash MCU can be reset using the RESET pin, power-on reset,

Watch-Dog Timer (WDT), Stop-Mode Recovery, or Voltage Brown-Out (VBO) warning

signal.

On-Chip Debugger

The Z8FMC16100 Series Flash MCU features an integrated On-Chip Debugger (OCD).

The single-pin OCD interface provides a rich set of debugging capabilities, such as read-
