Microchip introduces a new Power Monitoring IC With High-Accuracy Signal Acquisition

Posted on by Leave a comment

Microchip Technology Inc., a leading provider of microcontroller, mixed-signal, analog and Flash-IP solutions, today announced a new power monitoring IC, the MCP39F501.  This device is a highly integrated, single-phase power-monitoring IC designed for real-time measurement of AC power.  It includes two 24-bit delta-sigma ADCs, a 16-bit calculation engine, EEPROM and a flexible two-wire interface.  An integrated low-drift voltage reference in addition to 94.5 dB of SINAD performance on each measurement channel allows accurate designs with just 0.1 % error across a 4000:1 dynamic range.

PIC32 Bluetooth Audio Development Kits

The PIC32 Bluetooth Audio Development Kit that ships with audio streaming demo code delivers up to 24-bit, 192 kHz audio and has been tested with over 100 different Bluetooth audio enabled devices, spanning 18 different manufacturers.  The Bluetooth Hardware module and the Bluetooth A2DP audio software have been Bluetooth.org certified, saving the developer significant certification costs.  The modular design allows developers to swap out the included daughter boards (one for Audio and one for Bluetooth), to create their own custom versions with their preferred audio and wireless solution.  The kit also supports USB Host and Device connectivity, Apple® device authentication module interface, a 2-inch color LCD, five general-purpose button switches, 5 LEDs and a Plug-In-Module interface for PIC32 microcontroller upgrades.  The PIC32MX450F256 MCU is included which runs at 80 MHz with 256 KB Flash and 64 KB RAM.  With such a broad feature-set and flexibility, the kit makes an excellent general purpose development tool.

Microchip introduces new temperature sensors with 1.8V SMBus and I2C™ Interface

Microchip Technology Inc. has announced a new six-member family of temperature sensor ICs called the EMC118X.  This is the world’s first family of temp sensors with 1.8V SMBus and I2C™ communications, which is required for interfacing to the latest generation of smartphone, tablet and PC chipsets.  Additionally, this integrated low-voltage I/O support reduces cost and board space because it is accomplished without an external voltage level shifter.  These are also the first temp sensors to use an advanced sample-frequency-hopping filter, which enables temperature-monitoring traces of up to 8 inches in noisy environments with accurate readings.  The EMC118X family serves a broad range of applications in the mobile, commercial and embedded computing markets, by combining the above features with options for dual, triple and quad temperature monitoring, along with hardwired system-shutdown settings that can’t be overridden by software.

Temperature and relative humidity display with adaptive brightness control

Posted on by 9 comments

The objective of this project is to illustrate a technique of implementing adaptive brightness control to seven segment LED displays. It consists of a closed loop system that continuously assesses ambient light condition using an inexpensive light-dependent resistor (LDR) and uses that information to adjust the brightness of the display. For the proof of concept, the technique is applied to construct a digital temperature and relative humidity meter that adapts the brightness of the seven segment LED displays to the surrounding lighting conditions. There are 8 seven segment LED displays used in this project and they are all driven by one MAX7219 chip. The ambient temperature and relative humidity are measured using the DHT11 sensor. The microcontroller used in this project is PIC12F683, which is a low-pin-count (8) device from 8-bit PIC microcontroller family. Auto-adjusting the brightness of the seven-segment LED display with surrounding illumination enhances the readability in all ambient lighting conditions.
