Microchip Technology Inc. has expanded the PIC16F75X family of 8bit MCUs featuring intelligent analogueand core-independent peripherals. According to the company, the series is intended for general-purpose applications, as well as power supplies, battery charging, LED lighting, power management and power control/smart energy applications.

The PIC16F753 offers all the key features of the PIC12F752, 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, detailed Microchip. Additionally, the PIC16F753 offers an op amp with 3MHz of gain bandwidth product (GBWP), and a slope compensation circuit to help in switch mode power supply applications. Additionally, the MCU 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, added the company.

With increased intelligent analog capabilities, the PIC16F753 helps boost system performance and efficiency while reducing system costs, especially for newer LED-lighting and smart-energy applications. With its numerous on-chip general-purpose and specialized peripherals, including the integrated COG, high performance comparators and 50mA outputs for direct FET drive, the PIC16F753 MCU meets the needs of various 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, Microchip indicated.

The PIC16F753 is supported by Microchip’s standard suite of world-class development tools, including the PICDEM Lab Development Kit (part # DM163045, Rs.7,336.41 ($134.99)), the PICkit 3 (part # PG164130, Rs.2,442.93 ($44.95)) and the PICkit Low-Pin Count Demo Board (part # DM164130-9, Rs.1,412.50 ($25.99)). A free reference design for a high-power LED flashlight is available for this product.

The PIC16F753 is available for sampling in a 16-pin 4 x 4mm QFN package, as well as 14-pin PDIP, SOIC and TSSOP packages. Pricing starts at Rs.32.61 ($0.60) each, 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.
