This application note describes how to optimize the accuracy of the ST62 family micro-controllers' internal A/D converter. It includes instructions on how to filter analog input noise, how to put the MCU in wait state to minimize power supply noise, and how to make several successive A/D conversions and take an average of the results.
This document provides guidance on how to choose a resonator or quartz crystal in order to achieve reliable oscillation with the ST62 Microcontroller. The document first provides the major resonator parameters useful for a design. It then proposes measurement methods to ensure a safe oscillation.
This application note describes low-cost reset circuits for ST6 microcontrollers, including external reset circuitry and internal low voltage detector (LVD) reset circuitry, providing power-up and power-down monitoring, and delay power-on reset.
This note provides information on the steps required in order to perform in-circuit programming of ST62Exxx EPROM or OTP devices for both on-chip EPROM and EEPROM.
This application note describes how to generate a digital signal locked in phase and frequency (PLL) with a calibrated delay starting from an active edge on the Auto-reload timer input pin.
This application note describes how to use the ST62 Auto-reload Timer (ARTimer) to generate a PWM signal with tunable frequency and duty cycle. As an example, the generation of a 31.25kHz PWM signal with duty cycle proportional to an analog input voltage is presented.
This document describes the concepts of movement detectors for noisy environments. The use of microcontrollers can improve the performance of traditional movement detectors.
This application note explains the architecture and functionality of the I/O ports in the ST62 series microcontrollers, and provides guidance on how to use these features safely. The ST62 series is suitable for industrial control and other applications.
