February 29, 2012 - Microchip Technology announced PIC12F(HV)752 family of 8-bit microcontrollers (MCUs) featuring analog 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 program 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 specialized peripherals, including the integrated COG, high performance comparators, 50mA outputs for direct FET drive, the PIC12F(HV)752 MCUs meet these needs.
The high-voltage variant in the family – the PIC12HV752 MCU – 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.
Development support
The PIC12F(HV)752 MCUs are supported by Microchip's standard suite of world-class development tools, including the MPLAB Integrated Development Environment (IDE), and the PICkit 3 (part # PG164130), MPLAB REAL ICE (part # DV244005), and MPLAB ICD 3 (part # DV164035) debuggers/programmers. Engineers can also use Microchip's HI-TECH C Compiler for PIC10/12/16 MCUs (part # SW500010 and SW500005).
Packaging and availability
The PIC12F752 MCU is available in a 8-pin 3 mm x 3 mm DFN package, as well as 8-pin PDIP and SOIC packages. The PIC12FHV752 is available in the same package options.
