Microchip announces a new family of 8-bit microcontrollers (MCUs) 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 (COG) 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. Engineers are constantly challenged to increase system performance and efficiency while reducing system costs, especially for newer LED-lighting and battery-charging applications. With their numerous on-chip, general-purpose and specialised peripherals, including the integrated COG, high-performance comparators and 50mA outputs for direct FET drive, the PIC12F(HV)725 MCUs meet these needs. The high-voltage variant, PIC12HV752, incorporates a shunt regulator that allows operation from 2V to an unspecified user-defined maximum voltage level, with less than 2mA operation current.
This high-voltage variant is ideal for cost-sensitive applications with high-voltage power rails. Additionally, the 4-channel, 10-bit ADC can be used to implement various sensors and mTouch™ sensing applications, including capacitive touch.
The PIC12F(HV)725 MCUs are supported by Microchip’s standard suite of world-class development tools, including the MPLAB® Integrated Development Environment (IDE); the PICkit™ 3 (PG164130) priced at $44.95 each; MPLAB REAL ICE™ (DV244005) priced at $499.98 each; and MPLAB ICD3 (DV164035) debugger/programmer priced at $189.99. Engineers can also use Microchip’s HI-TECH C® Compiler for PIC10/12/16 MCUs (SW500010 and SW500005). The PIC12F752 and PIC12FHV752 MCUs are available in 8-pin 3 mm × 3 mm DFN, as well as 8-pin PDIP and SOIC packages.
