Summary of PIC18F-Q84 FAMILY OF MICROCONTROLLERS
Microchip’s PIC18-Q84 family are 8-bit PIC microcontrollers that combine numerous configurable integrated peripherals (CIPs) with CAN FD communications. Available in packages up to 48 pins and up to 128 KB Flash, they provide customizable timers, automated analog signal analysis, DMA, vectored interrupts, standard serial interfaces (I2C, SPI, UART with DMX/DALI/LIN), JTAG boundary scan, and 32-bit CRC with memory scan on boot to enhance system safety and reduce development time by offloading tasks to hardware.
Parts used in the PIC18-Q84 Project:
- PIC18-Q84 family MCU (up to 48-pin, up to 128 KB Flash)
- CAN FD module (integrated in MCU)
- Direct Memory Access (DMA) controller (integrated)
- I2C interface (integrated)
- SPI interface (integrated)
- UART interface with support for asynchronous, DMX, DALI, and LIN (integrated)
- Vectored interrupt (VI) subsystem (integrated)
- Customizable timers (CIPs)
- Automated analog signal analysis peripheral (CIP)
- JTAG boundary scan (integrated)
- 32-bit cyclic redundancy check (CRC) with memory scan on boot (integrated)
Microchip’s PIC18-Q84 8-bit PIC® MCUs with an extensive array of CIPs and CAN FD
The PIC18-Q84 family of microcontrollers (MCUs) from Microchip Technology expands the 8-bit PIC MCUs by combining an extensive array of CIPs with controller area network flexible data rate (CAN FD). These MCUs contain time-saving CIPs in up to 48-pins with up to 128 KB of Flash memory. The family offers increased flexibility with customizable timers and automated analog signal analysis for real-time response. Additionally, they include industry-standard features like the JTAG boundary scan, 32-bit cyclic redundancy check (CRC) with memory scan on boot for added system safety. Users can benefit greatly from the saved time since it is significantly easier to configure a hardware-based peripheral instead of writing and validating an entire software routine to accomplish a task.
