PIC18F K83 8-Bit Microcontroller Family

Microchip Technology's PIC18 K83 family in 8-bit MCUs that combine an extensive array of CIPs with the PIC18 CAN product line. These cost-optimized MCUs contain 15 time-saving CIPs in 28-pins with up to 64 KB of Flash memory. These products are ideal for applications using CAN in the medical, industrial, and automotive markets, such as motorized surgical tables, asset tracking, ultrasound machines, automated conveyors, and automotive accessories. System designers can benefit greatly by saving time, as it is significantly easier to configure a hardware-based peripheral, as opposed to writing and validating an entire software routine to accomplish a task. The devices include a full complement of core independent peripherals, including cyclic redundancy check (CRC) with memory scan, for ensuring the integrity of non-volatile memory; direct memory access (DMA) enabling data transfers between memory and peripherals without CPU involvement; windowed watchdog timer (WWDT) for triggering system resets; 12-bit analog-to-digital converter with computation (ADC²) for automating analog signal analysis for real-time system response; and complementary waveform generator (CWG) for enabling high-efficiency synchronous switching for motor control.

The CAN module works with CAN 2.0 B and is fully backwards compatible with previous CAN modules. The products include the memory access partition (MAP), which supports customers in data protection and bootloader applications. Device information area (DIA) is a dedicated memory space for factory-programmed device ID and peripheral calibration values. Additionally, the MCUs have improved serial communications, including UART with support for asynchronous, DMX, DALI, and LIN protocols along with higher-speed, standalone I²C and SPI serial communication interfaces. The direct memory access (DMA) controller eliminates the need for CPU involvement in data transfers between all memory spaces and peripherals, thereby reducing the number of interrupts and improving peripheral performance. The products offer intelligent analog peripherals including zero cross detect (ZCD), on-chip comparator, and a 12-bit ADC² automating capacitive voltage divider (CVD) techniques for advanced touch sensing, averaging, filtering, oversampling, and threshold comparison. The rich feature set included in these microcontrollers make them suitable for a wide variety of IoT applications.
