Flash MCUs are optimised for motor
control
Microchip has developed its first general-purpose Flash PIC microcontrollers with peripherals for more cost-effective control of fans or small motors.
Microchip has developed its first general-purpose Flash PIC microcontrollers with peripherals for more cost-effective control of fans or small motors The 14-pin PIC16F616/610 and the 8-pin PIC12F615/609 microcontrollers can substantially reduce component count and cost with specialised peripherals such as full-bridge pulsewidth modulation (PWM) with deadband control, timer gate control for pulsewidth measurement, a comparator with hysteresis for Hall-effect sensor interfaces, and an A/D convertor for temperature and other monitoring functions

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.
As an example application, when used in cooling fan controls, the PIC16F616/610 and PIC12F615/609 Flash microcontrollers can provide greater functionality than discrete fan-control components, including linear speed control, improved dynamic response and a firmware-customisable design.
The PIC16HV616/610 and PIC12HV615/609 variants add an internal shunt regulator which allows the PIC microcontroller to run from higher voltage rails without the addition of external voltage regulators.
Many higher voltage applications, such as motor controls and power supplies, require components to step down the input voltage.

Flash microcontrollers run up to 10MIPS
Microchip's new PIC18F010 and PIC18F020 Flash microcontrollers offer an industry-leading performance of 10MIPS, 4Kbyte of program memory, 256byte of user RAM and 64byte of EEPROM.
These new HV PIC microcontrollers allow engineers to design systems running from 2.0V up to a user-defined maximum without having to add a regulator, reducing cost and board space even further.
In addition, such applications often require intermediate voltages for power drivers and other components.
The PIC16F616/HV616 family can provide these using the built-in S/R latch to implement a switch-mode power supply.
Specific application examples include home appliances, cooling-fan and other motor control, power tools, system control and monitoring, battery chargers and power supplies.
These microcontrollers are supported by Microchip's development tools, including the free MPLAB IDE (integrated development environment), the low-cost MPLAB ICD 2 (in-circuit debugger) and the MPLAB PM3 universal device programmer.
In addition, the PICkit 2 starter kit (DV164120) enables engineers to easily and cheaply begin development with the PIC16F616/HV616 family.
The kit uses a full-speed USB 2.0 connection, which allows faster programming and firmware upgradeability, and also provides a power supply for the programmer and target applicationboard.
The PIC16F616/610 and PIC16HV616/610 microcontrollers are available in 14-pin PDIP, SOIC, TSSOP and QFN packages.
The PIC12F615/609 and PIC12HV615/609 are available in 8-pin PDIP, SOIC, DFN and MSOP packages.
All the devices are available now for sampling and volume production.
