2/2/2005 - Microchip Technology Inc., a leading provider of microcontroller and analog semiconductors, announced the PIC16F785, which provides a complete set of integrated peripherals for cost-effective digital control in power-conversion designs. This 8-bit Flash microcontroller has a large complement of onboard analog peripherals, including analog-to-digital converters (A/Ds), comparators, a voltage reference and two operational amplifiers (op amps), which also appeals to a broad range of sensing and closed-loop control applications.
The PIC16F785 offers engineers the flexibility to cost effectively address a wide variety of power- conversion topologies and parameters in applications such as Switch Mode Power Supplies (SMPS) and battery chargers. Digital control in power-conversion applications is emerging as a viable means to manage the increasingly complex power requirements in today's electronic systems, which require intelligent and deterministic control of multiple power rails, startup conditions, fault detection, exception handling, and complex battery-charging algorithms. The PIC16F785 makes it easier for power-supply designers to utilize the programmability of digital control in power-conversion applications by providing the familiar analog building blocks within a programmable microcontroller.
"The PIC16F785 combines unrivaled integration of mixed-signal capabilities with the flexibility and re-programmability of a Flash microcontroller," said Steve Drehobl, vice president of Microchip's Security, Microcontroller and Technology Division. "The PIC16F785 is an excellent fit for power-conversion applications, but our customer base is very creative and will find many applications in all the markets Microchip serves, including appliance, automotive, consumer and industrial."
By providing two general-purpose op amps with a 3 MHz Gain Bandwidth Product (GBWP) and 5 millivolt input offset voltage, the PIC16F785 allows designers the flexibility to implement filters, input gains stages and other functions. These two op amps, combined with an integrated 1.2V bandgap voltage-reference output and two high-speed (40 nanosecond) comparators, put the PIC16F785 in a class of its own when it comes to integrated analog peripherals for input sensing. In addition, the PIC16F785's rich standard features make it an excellent general-purpose microcontroller for closed-loop control applications. Other key features include:
The PIC16F785 is supported by the full suite of Microchip's high-performance development tools, including: PICkit™ 1 Flash Starter Kit, MPLAB® IDE (Integrated Development Environment), MPLAB ICD 2 (In-Circuit Debugger), PRO MATE® II and MPLAB PM3 universal device programmers, PICSTART® Plus cost-effective development system. Application notes related to power conversion are currently being created.
