Microchip Technology recently expanded its PIC16F75X line of 8bit microcontrollers (MCUs). The MCUs feature intelligent analogue and core-independent peripherals aimed at general purpose applications as well as power supplies, battery charging, LED lighting, power management and power control/smart energy applications.

The new PIC16F753 MCU builds on the PIC12F752 and offers all its key features, such as the 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.

The PIC16F753 also offers an Op Amp with 3MHz of Gain Bandwidth Product (GBWP), and a slope compensation circuit to help in Switch Mode Power Supply applications. It features 3.5KB of self read-write program memory, 128B of RAM, an on-chip 10bit ADC, 9bit DAC, Capture Compare PWM modules, high-performance comparators, and two 50mA capable I/Os, enabling engineers to increase overall system capabilities and reduce costs.

With increased intelligent analogue capabilities, the PIC16F753 helps boost system performance and efficiency while reducing system costs, especially for newer LED-lighting and smart-energy applications. The high-voltage version 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 8-channel, 10bit ADC can be used to implement various sensors and mTouch sensing applications, including capacitive touch.

The PIC16F753 is available now for sampling in a 16-pin 4x4mm QFN package, as well as 14-pin PDIP, SOIC and TSSOP packages. It is supplied in 10,000-unit quantities. The PIC16F753 is also available in a High Voltage (HV) variant for all packages. Volume production is expected in July.
