PIC18F47Q83T-I/PT - 128KB Flash 8-bit MCU w/ CAN | Microchip
The Microchip Technology PIC18F47Q83T-I/PT is a 64 MHz 8-bit PIC microcontroller with 128 KB Flash, 13 KB SRAM, and 1 KB EEPROM, housed in a 44-pin TQFP (10x10 mm) tape-and-reel package. It integrates Core Independent Peripherals (CIPs) including a CAN FD controller, a 12-bit ADC with Computation (ADC2), a 5-bit DAC, DSM (Data Signal Modulator), PWM modules, and CIPS, alongside I2C, SPI, and UART serial interfaces.
An 8-bit PIC microcontroller (MCU) is a Harvard-architecture RISC processor widely used in embedded control for its deterministic instruction execution, low power consumption, and rich peripheral integration. Within the broader MCU taxonomy, 8-bit MCUs sit below 16-bit and 32-bit Cortex-M devices in computational capability but excel in cost-sensitive, real-time control applications. The PIC18 family adds enhanced peripherals, larger memory, and C compiler support (MPLAB XC8) while remaining pin-compatible with the legacy PIC16 baseline, making it a workhorse for industrial, automotive, and IoT designs.
Key features of the PIC18F47Q83T-I/PT include 128 KB self-programmable Flash with device ID protection, a 10-bit slope ADC2 with automated averaging, oversampling, and threshold comparison, a 5-bit DAC with internal reference, and four 16-bit PWM outputs. The device also exposes 36 digital I/O pins, four CWG (Complementary Waveform Generator) channels, and a Hardware Limit Timer for deterministic motor and lighting control. Operating voltage is 2.5 V to 5.5 V, and the operating temperature range is -40C to +85C (industrial grade).
The PIC18F47Q83 architecture combines the legacy PIC18 instruction set with modern CIP blocks, allowing developers to offload logic such as signal conditioning, motor commutation, and protocol handling from the CPU. The device supports up to 64 MHz operation from an internal 64 MHz HFINTOSC, eliminating external crystals in many designs, and integrates a CAN FD peripheral for automotive and industrial networking.
Typical applications include CAN node endpoints in industrial automation, BLDC motor control, LED lighting drivers, IoT sensor hubs, and USB-to-CAN bridges. The combination of CAN FD, PWM, and ADC2 with computation makes the PIC18F47Q83 particularly well-suited to sensor-rich, real-time control systems.
When designing with this MCU, budget carefully for the 44-pin TQFP footprint's thermal envelope. Although the part is low-power (typical active current below 10 mA at 64 MHz), high GPIO toggle rates and ADC sampling can raise junction temperature in enclosed housings. Decouple VDD with 100 nF ceramic caps adjacent to each power pin, and reserve RA5 as MCLR with a 10 kohm pull-up per Microchip's recommendation.
