Wegatech Electronic Releases New Design Using Microcontroller with Closed Loop Control and Safety Monitoring

Kuala Lumpur, Malaysia, November 25, 2014 --(PR.com)-- Wegatech Electronic, a company located in Malaysia currently support new microcontroller family from Microchip with Proportional Integral Derivative.

This new microcontroller from Microchip is offering a completely core independent calculations, with the capability to perform 16-bit math and PID operations. The family also includes the Angular Timer (AngTmr), which is a hardware module that calculates the rotational angel in functions, such as motor control, TRIAC control, or Capacitive Discharge Ignition (CDI) systems. Regardless of speed, the AngTmr allows recurring interrupts at a specific rotational or sinusoidal angle without using the core’s computation. The CIPs can be configured to perform a host of given functions that increase execution speeds and decrease software requirements. Offloading these functions frees up the CPU to do other tasks, consumes less program memory, and reduces the overall power consumption of the MCU.

In addition to the MATH ACC and AngTmr, the microcontroller features several other peripherals designed to ease implementation and add flexibility of various functions. The 24-bit Signal Measurement Timer (SMT) performs high-resolution measurements of digital signal, in hardware, resulting in more precise and accurate measurements. This is ideal for speed control, range finding and RPM indicators. This family also includes the Zero Cross Detect (ZCD) module, which can monitor AC line voltage, and indicate zero crossing activity. Simplifying TRIAC control applications greatly reduces both CPU demand and BOM cost. In combination with the new high-current I/Os (100 mA) and the proven Configurable Logic Cell (CLC) along with I2C™, SPI and EUSART for communications, this integration helps speed design, eases implementation and adds flexibility.

This family also supports the implementation of safety standards such as Class B and UL 1998 or fail-safe operations by combining the Windowed Watchdog Timer (WWDT) which monitors proper software operation within predefined limits, improving reliability and Cyclic Redundancy Check with Memory Scan (CRC/SCAN) that detects and scans memory for corrupted data. Along with the Hardware Limit Timers (HLT), which detect hardware fault conditions (stall, stop, etc.), engineers can now enable safety and monitoring functions in their applications with minimum to zero involvement of the CPU. Along with all these features, the family offers low-power XLP technology and is provided in small-form-factor packages, ranging from 8-, 14- and 20- pin packages.
