Easy interfacing to faster microcontrollers
Microchip has added two new devices to its PIC16C92X family of 8bit one-time-programmable microcontrollers with integrated liquid-crystal display controller.
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 (SMPSs) 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 use the programmability of digital control in power-conversion applications by providing the familiar analogue building blocks within a programmable microcontroller.

Microchip's new 2.5 V micropower operational amplifier is available in a tiny SOT-23 package.
"The PIC16F785 combines unrivalled integration of mixed-signal capabilities with the flexibility and reprogrammability 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 3MHz gain bandwidth product (GBWP) and 5mV 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 (40ns) comparators, put the PIC16F785 in a class of its own when it comes to integrated analogue 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: high speed, two-phase PWM with asynchronous feedback; 3584byte Flash program memory, 256byte EEPROM and 128byte RAM; 8MHz precision internal oscillator; Nanowatt Technology power-management features; 12 channels of 10bit A/D conversion; a standard capture/compare/PWM (CCP) module; and software-controlled brownout reset and an extended watchdog timer.
The PIC16F785 is supported by the full suite of Microchip's high-performance development tools, including: PICkit1 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 10,000-unit quantities starting at $1.75.
