Microchip PIC16F785T-I/ML: A Versatile 8-Bit Mixed-Signal Flash Microcontroller

The Microchip PIC16F785T-I/ML stands as a powerful and highly integrated solution in the realm of 8-bit microcontrollers. Designed for applications demanding robust analog and digital functionality, this MCU combines a high-performance core with a rich set of peripheral features, making it an ideal choice for a wide range of embedded control and system monitoring tasks.

At its heart, the PIC16F785 features an enhanced mid-range PIC16 architecture with a 14-bit wide instruction set and an 8-bit data path. Operating at speeds up to 20 MHz, it delivers a solid 5 MIPS of performance, ensuring responsive control for real-time applications. A significant advantage is its on-chip Enhanced Flash program memory with self-read/write capability, offering 7 KB of space for application code, complemented by 256 bytes of EEPROM and 368 bytes of RAM for efficient data handling.

The "mixed-signal" designation is truly earned through its comprehensive suite of analog peripherals. It integrates a 10-bit Analog-to-Digital Converter (ADC) with up to 11 channels, enabling precise measurement of multiple sensor inputs. Furthermore, it includes two analog comparators and a 5-bit Digital-to-Analog Converter (DAC), providing essential tools for signal conditioning and generation without external components. A standout feature is the Complementary Waveform Generator (CWG), which can produce non-overlapping PWM signals crucial for controlling half-bridge and full-bridge drivers in motor control and power conversion systems.

For digital control and communication, the microcontroller is equally capable. It offers PWM modules for precise power management, a Master Synchronous Serial Port (MSSP) that can be configured as either I²C or SPI for communication with a vast ecosystem of peripherals, and an Enhanced Universal Synchronous Asynchronous Receiver Transmitter (EUSART) for serial communication protocols like RS-232 and RS-485.

Housed in a compact 5x5mm 28-pin QFN (ML) package, the PIC16F785T-I/ML is designed for space-constrained applications. Its extended industrial temperature range (-40°C to +85°C) ensures reliable operation in harsh environments, from industrial automation and automotive subsystems to consumer appliances and sensor nodes.

ICGOODFIND: The PIC16F785T-I/ML is a highly integrated, cost-effective MCU that excels in mixed-signal control. Its potent combination of a capable core, substantial memory, advanced analog features like the ADC and DAC, and specialized digital peripherals like the CWG, makes it a superior choice for designers seeking to minimize external components and maximize functionality in their embedded designs.
