PIC18F K83 Product Family

8-Bit MCUs That Combine CAN
and Core Independent Peripherals

The PIC18 K83 family continues our longstanding tradition of innovation in 8-bit MCUs by combining an extensive array of Core Independent Peripherals (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.

Improve Response Time
in CAN System Networks

Intelligent Analog

The products offer intelligent analog peripherals including Zero Cross Detect (ZCD), on-chip comparator, and a 12-bit ADC with Computation (ADC2) automating Capacitive Voltage Divider (CVD) techniques for advanced touch sensing, averaging, filtering, oversampling, and threshold comparison.

Improved Peripheral Performance

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.

Faster Interrupt Response Times

The Vectored Interrupt (VI) reduces response time by providing hardware ensured interrupt latency.

Enhanced System Features

The Controller Area Network (CAN) module works with CAN 2.0B 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.

Development Made Easy

The PIC18F K83 family will be supported by MPLAB® Code Configurator (MCC), a free software plug-in that provides a graphical interface to configure peripherals and functions specific to your application. MCC is incorporated into our award-winning development environments, the downloadable MPLAB X IDE and the cloud-based MPLAB Xpress IDE.

Direct Memory Access (DMA)
Direct Memory Access (DMA) - Direct Memory Access (DMA) is used to move data among Flash, EEPROM, RAM and peripherals without intervention from the CPU and in the background of CPU operation.
Memory Access Partition (MAP)
Advanced Memory Features - Memory Access Partition (MAP) 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.
Peripheral Module Disable (PMD)

Power Conserving Functionality - IDLE and DOZE low-power modes allow applications to optimize device performance and power consumption. The Peripheral Module Disable (PMD) allows unused peripherals to be turned off individually, further reducing power consumption.  PIC18F "K83" devices feature the industry leading eXtreme Lower Power (XLP) technology.
