Chandler, Ariz.-- Microchip Technology Inc.'s PIC16F785 flash microcontroller provides system designers with a complete set of integrated peripherals that are said to address a wide variety of power- conversion topologies and parameters in applications such as Switch Mode Power Supplies (SMPS) and battery chargers.
This 8-bit flash MCU has a large complement of onboard analog peripherals, including analog-to-digital converters, two high-speed comparators, a voltage reference and two operational amplifiers, which also appeals to a broad range of sensing and closed-loop control applications.
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, according to Steve Drehobl, vice president of Microchip's Security, Microcontroller and Technology Division.
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.
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.
General sampling is available now, and volume production is expected in February, for the PIC16F785 microcontroller. Package options include PDIP, SOIC, SSOP and 4x4 QFN, with unit pricing in 10k quantities starting at $1.75.
