PIC18F26K83-I/ML - 8-Bit 64MHz 64KB Flash MCU w/ CAN | Microchip

The Microchip Technology PIC18F26K83-I/ML is a 64 MHz 8-bit PIC18 XLP microcontroller with 64 KB Flash, 4 KB RAM, and integrated CAN, offered in a 28-pin QFN (6x6 mm) package with an exposed thermal pad. It operates across 2.3V-5.5V with XLP (eXtreme Low Power) technology, integrates a 12-bit ADC with Computation (ADC2) supporting Capacitive Voltage Divider (CVD) touch sensing, and provides Functional Safety (FuSa) features for safety-critical designs. A microcontroller (MCU) is a single-chip computer containing a CPU, memory (Flash/RAM), and programmable peripherals that engineers configure to read sensors, drive actuators, and exchange data via serial busses. PIC18 MCUs use a modified Harvard architecture optimized for deterministic real-time control, and the K-series extends that line with enhanced peripherals like ADC2, DMA, and CIP (Core Independent Peripherals). Within Microchip's 8-bit portfolio, the PIC18F26K83 sits in the K83 sub-family that combines an MSSP-based CAN module, 12-bit differential ADC, and XLP battery-friendly sleep currents below 100 nA. Key features of the PIC18F26K83-I/ML include 64 KB self-programmable Flash (32K x 16 words), 4 KB SRAM, 1 KB EEPROM, four 16-bit timers, two I2C, two SPI, four UART, and a CAN 2.0B module. ADC2 automates oversampling, averaging, and threshold comparison without CPU intervention, freeing cycles for higher-level control loops. The device also includes a Peripheral Pin Select (PPS) engine that remaps most digital peripherals to any I/O pin, simplifying PCB routing on dense boards. Designed for industrial-grade reliability, the PIC18F26K83-I/ML supports -40C to +85C operation, watch timers, windowed WDT, and CRC/SCAN memory integrity checking. The 28-QFN exposed pad provides a low theta_JA footprint suitable for compact industrial modules and energy-meter PCBs that previously required larger SSOP packages. Internal DMA moves data between peripherals and RAM without CPU load, enabling efficient noise-filter pipelines and high-speed UART/CAN traffic. Typical applications include industrial CAN node controls (sensor hubs, motor pre-drivers, building automation), touch-sensing human-machine interfaces using CVD, automotive body and accessory ECUs, e-metering, and battery-powered IoT sensor nodes. Designers benefit from MPLAB X IDE, MCC pin/clock code generators, and the PIC18F26K83 Plug-In Module (MA180037) for rapid prototyping on Microchip development boards. When selecting this part, consider that the 28-QFN variant (-I/ML, industrial -40 to +85C) is drop-in compatible with the 28-SSOP (-I/SS) and 28-SOIC (-I/SO) variants, but PCB re-layout is required to migrate between QFN and leaded packages. Designers migrating from the older PIC18F25K80 gain ADC resolution (12-bit vs 10-bit), CAN-FD capability, DMA, and CIP peripherals with software-level compatibility through the XC8 toolchain. This page synthesizes distributor pricing, drop-in alternatives sourced from Microchip's K80/K42 families, design notes covering ADC2 configuration and CAN bus termination, and an AEO-optimized FAQ tailored to engineers evaluating this MCU for new designs or replacement of legacy K80 silicon.

Key features of this part include a 12-bit Analog-to-Digital Converter with Computation (ADCC) supporting capacitive voltage divider (CVD) touch sensing, three 16-bit dual PWMs providing six PWM outputs, six Direct Memory Access (DMA) controllers, vectored interrupts with selectable priority and 3-instruction-cycle fixed latency, and CLC (Configurable Logic Cell) hardware customization blocks. The device operates from 1.8 V to 5.5 V and includes XLP extreme-low-power sleep modes. The architecture is built on an enhanced PIC18 Harvard core with 16-bit instructions, a hardware multiplier, and a 31-level stack. Internal high-frequency oscillator, PLL, and low-power LFINTOSC minimize external components. Six DMA channels offload data movement between peripherals and memory, freeing the CPU for application logic and improving real-time response in motor control, lighting, and sensor-fusion designs. Typical applications include capacitive touch user interfaces, BLDC/PMSM motor control using the 16-bit PWMs and PGA-equipped ADCC, LED lighting and signage controllers, IoT sensor nodes, battery-powered consumer appliances, and industrial control front-ends. The combination of XLP sleep currents and DMA-driven peripherals enables long battery life in always-on systems. When designing with the PIC18F26Q43T-I/STX, follow Microchip AN2931 and AN2407 for PCB layout guidelines, place a 0.1 µF decoupling capacitor on each VDD pin with trace length under 5 mm, and use the MPLAB X IDE with MPLAB Code Configurator (MCC) for peripheral setup. Keep in mind that the 28-pin VQFN variant differs from the 28-pin SPDIP/SOIC variants only in thermal pad connection—review the pinout diagram before routing.

PIC18F26Q84-E/SO - 8-bit MCU, 64KB Flash, CAN FD, 28-SOIC

The Microchip Technology PIC18F26Q84-E/SO is an 8-bit PIC microcontroller with 64KB Flash, 64 MHz CPU speed, and Controller Area Network Flexible Data Rate (CAN FD) support, housed in a 28-pin SOIC (SO) wide-body package. It integrates an extensive set of Core Independent Peripherals (CIPs) including CWG, CCP, DSM, NCO, math accelerator, 12-bit ADC, and high-speed comparators, enabling deterministic real-time control without CPU intervention. What is a PIC18-Q84 microcontroller? The PIC18-Q84 family is part of Microchip's 8-bit PIC microcontroller portfolio, combining Core Independent Peripherals (CIPs) with CAN FD connectivity for automotive and industrial applications. These cost-optimized MCUs include time-saving CIPs in 28/40/44/48-pin packages, sit within the broader PIC18 family of 8-bit microcontrollers, and address the category of small-footprint, low-power embedded controllers for sensor and actuator networks. Key features include 64 KB Flash program memory, 4 KB SRAM, 1 KB EEPROM, a 12-bit differential ADC with Computation, up to six PWM channels, two UART, two SPI, two I2C, two CAN FD, and an integrated math accelerator for sensor math pipelines. The device operates from 2.3V to 5.5V and is qualified for the -40C to +125C extended industrial temperature range, supporting harsh-environment deployments. The PIC18F26Q84 architecture pairs a Harvard RISC CPU with a rich CIP block, allowing hardware-driven peripheral actions (e.g., ADC-triggered PWM, timer-triggered ADC) that free the core for higher-level tasks. This CIP-based design yields deterministic latency and reduced firmware complexity compared with CPU-driven interrupt architectures, while the on-chip CAN FD peripheral brings automotive-grade bus bandwidth for sensor and actuator networks. Typical applications include CAN-based sensor nodes, automotive body and chassis ECUs, industrial automation controllers, building automation gateways, and battery management systems. The wide temperature range and CAN FD make it especially well suited to vehicle networks and factory-floor control loops requiring deterministic, real-time response. Design consideration: when using CAN FD, ensure that the bit-time configuration matches the chosen CAN transceiver and bus topology; for 28-pin SOIC layouts, dedicate adequate copper to the exposed thermal pad area to keep junction temperature within range at full CPU speed.

A PIC (Peripheral Interface Controller) is a family of 8-bit, 16-bit, and 32-bit microcontrollers manufactured by Microchip Technology, featuring a RISC architecture with Harvard bus design. PIC microcontrollers are widely used in embedded systems due to their low cost, low power consumption, and rich peripheral integration. Within the product taxonomy, the PIC18F26Q84 belongs to the broader category: microcontroller -> 8-bit MCU -> PIC18 family -> PIC18-Q84 sub-family -> CAN FD enabled CIPs. Key features of the PIC18F26Q84-E/SP include 25 ADC channels with 12-bit resolution, a 10-bit DAC, multiple 16-bit timers, capture/compare/PWM peripherals, and a high-endurance Flash program memory rated for 10K erase/write cycles. The CAN FD peripheral supports data rates up to 8 Mbps, while the device operates from 1.8V to 5.5V supply voltage with low-power sleep, idle, and dozing modes for battery-powered applications. The instruction set is backward-compatible with earlier PIC18 devices, easing migration from older designs. The architecture pairs a modified Harvard RISC CPU with deterministic interrupt handling and a hardware multiplier, executing most instructions in one clock cycle at 64 MHz (15.6 ns instruction cycle). On-chip CIPs handle tasks like signal generation, waveform measurement, and motor control without CPU loading, allowing the CPU to focus on system-level logic and communication stacks. The device also includes configurable logic cells and a math accelerator for offloading arithmetic operations. Typical applications include automotive body and comfort modules, industrial sensor hubs, building automation, CAN FD node endpoints, motor control, LED lighting controllers, and battery management systems. The wide operating voltage and temperature range also suit industrial-grade PLCs and outdoor equipment. When designing with this device, ensure that the CAN FD bit-rate configuration matches the bus network topology, and that appropriate bus termination (typically 120 ohm at each end) is provided. Use Microchip's MPLAB X IDE with the XC8 compiler for firmware development. For migration from earlier PIC18F26K-series devices, verify the peripheral pin select (PPS) mapping as additional pins are remappable on the Q84 family.
