Microchip Technology Offers New PIC16F785 MCU

Microchip Technology Inc. (Chandler, AZ), a provider of microcontroller (MCU) and analog semiconductors, announced its new PIC16F785, which provides a complete set of integrated peripherals for cost-effective digital control in power-conversion designs. The eight-bit flash microcontroller has a large complement of onboard analog peripherals, including analog-to-digital converters, 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 is suitable for power-conversion applications, including appliances, automotive, consumer and industrial.

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 and battery chargers. 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.

By providing two general-purpose op amps with a 3 MHz gain bandwidth product and 5 mV input-offset voltage, the PIC16F785 allows designers the flexibility to implement filters, input gains stages and other functions. The two op amps, combined with an integrated 1.2 V bandgap voltage-reference output and two high-speed (40 ns) comparators, make the PIC16F785 suitable for closed-loop control applications. Other features include high-speed, two-phase PWM with asynchronous feedback; 8 MHz precision internal oscillator; nanoWatt technology power-management features; 12 channels of 10-bit A/D; standard capture/compare/PWM (CCP) module; and software-controlled brownout Reset and an extended watchdog timer.

General sampling is available now, and volume production is expected in February, for the PIC16F785 microcontroller. Package options include PDIP, SOIC, SSOP and 4×4 QFN, with unit pricing in 10,000-unit quantities starting at $1.75.
