Microchip Technology Inc. - 8-bit PIC Microcontrollers - next-gen peripherals - 18 June 2012

Microchip announces a new family of 8-bit microcontrollers featuring next-generation analogue and digital peripherals, making them ideal for general-purpose applications, as well as battery charging, LED lighting, ballast-control, power-conversion and system-control applications.

The PIC12F(HV)752 MCUs feature an integrated Complementary Output Generator peripheral that provides non-overlapping, complementary waveforms for inputs such as comparators and Pulse Width Modulation (PWM) peripherals, while enabling dead-band control, auto shutdown, auto reset, phase control and blanking control.

Additionally, the new MCUs feature 1.75 KB of self read-write programme memory, 64B of RAM, an on-chip 10-bit ADC, Capture-Compare PWM modules, high-performance comparators down to 40 ns response, and two 50 mA-capable I/Os, enabling engineers to increase overall system capabilities and reduce costs.

    Key Features
  • Mid-Range PIC® Architecture
  • Based on Microchip's mature 8-bit core providing POR, BOR, Interrupts and WDT to enable highly efficient circuits.
  • Self Read-Write Flash Program Memory
  • Serves as a low cost alternative to Data EE. This is very useful when an application requires remote updates, or needs to store system data or look up tables.
  • Analog Peripherals
  • The 4 channel, 10-bit ADC can be used to implement various sensors and mTouch™ applications. Fast 20 ns comparators can be used to implement efficient switching circuits.
  • Complementary Waveform Generator
  • Provides non-overlapping complementary waveform for various inputs like comparators, PWM; while affording enhanced features like dead band control, auto shutdown, auto reset, phase control and blanking control.
  • Digital to Analog Converter
  • The true 5-bit DAC offers the flexibility of output voltage range selection. The VDD or the external VREF pin can act as the reference to the circuit.
  • Capture Compare and PWM
  • This module can be utilized to implement variety of motor control and lighting applications.
  • High Voltage VDD Support
  • Allows for connection to an application that has high voltage rails, without the need of an external regulator. It promotes component cost and board area savings.

  • LED lighting
  • Lamp ballast
  • Automotive head and tail lamps
  • High Intensity Discharge (HID) lighting
  • LCD backlighting
  • Power factor correction
  • Battery monitoring and charging
  • Signal conditioning
  • Flyback AC-to-DC converter
  • Low voltage AC-to-DC converter
  • Synchronous DC-to-DC converter
