The PIC16(L)F1769 family includes intelligent analog and digital peripherals, including a tri-state operational amplifier, a 10-bit analog-to-digital converter (ADC), a 5/10-bit digital-to-analog converter (DAC), a 10/16-bit PWM, a high-speed comparator, and two 100mA high-current I/Os. By integrating these various combinations of peripherals, multiple independent closed-loop power channels and system management can be supported, and the design can be simplified to an 8-bit platform to improve efficiency and performance, while significantly reducing the number of components within the power conversion system.

In addition to power conversion peripherals, the PIC MCU provides unique hardware-based LED dimming control capabilities implemented by the interaction of a Delta Signal Modulator (DSM), operational amplifier, and 16-bit PWM. The combination of these peripherals creates switching control synchronization for the LED dimming engine, eliminating LED current overshoot and decay. Output switching synchronization facilitates smooth dimming and minimizes color shift, while also extending LED lifespan and reducing heat generation. Furthermore, this product family includes Core Independent Peripherals (CIPs) such as Configurable Logic Cells (CLCs), Output Generators (COGs), and Zero Cross Detectors (ZCDs). Designed to handle tasks without code or CPU intervention to maintain operation after initial setup, Core Independent Peripherals elevate 8-bit PIC MCU performance to a new level. As a result, complex control systems can be easily implemented, providing the flexibility to unleash developers' innovation. CLC peripherals enable the creation of custom logic and interconnects for applications, allowing for the reduction of interrupt delays and code space while adding functionality. COG peripherals are powerful waveform generators that produce complementary waveforms, supporting fine-tuning of key parameters such as phase, dead-band, blanking, emergency stop states, and error recovery strategies. This waveform generator is a cost-effective solution that reduces board space and component costs. ZCD detects when a high-voltage AC signal passes through ground and is ideal for TRIAC control functions.

The newly released 8-bit PIC MCU family provides multiple independent closed-loop power channels and system management capabilities, making it suitable for a wide range of power supplies, battery management, LED lighting, interior and exterior automotive lighting, and general-purpose applications. In addition to these features, the family incorporates EUSART, I2C™/SPI, and Ultra Low Power (XLP) technologies, all of which are available in a small 14-20 pin form factor package.

"The core of the PIC16F1769 family is the ability to interconnect peripherals to create application-specific custom functions," said Steve Drehobl, Vice President of Microchip's MCU8 product business unit. "By combining this with the ability to simultaneously control standalone closed-loop channels, it enables a new level of functionality not seen in existing low-cost 8-bit PIC MCUs."
