The part carries the -I (industrial) temperature grade spanning -40C to +85C and integrates rich Core Independent Peripherals (CIPs), a 12-bit ADC with Computation (ADC2), Configurable Logic Cells (CLC), Direct Memory Access (DMA), and UART/SPI/I2C serial interfaces. A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, volatile data memory, and peripheral subsystems on one die. PIC18F microcontrollers are 8-bit RISC-Harvard architecture devices in the broader PIC family, which sits hierarchically under microcontrollers -> embedded processors -> semiconductor devices. The K42 sub-family is the PIC18F24/25/45/46K42 line that introduces XLP (eXtreme Low Power) technology and Functional Safety (FuSa) diagnostics, positioning these parts at the high end of the 8-bit PIC portfolio.

The XLP idle/doze/sleep modes plus nanoWatt XLP peripherals enable typical sleep currents below 1 uA, which is essential for battery-powered nodes. Architecturally the device pairs a modified Harvard RISC core with a vectored interrupt controller (fixed-latency IVT) and a System Bus Arbiter that coordinates DMA, CPU, and CLC transactions without CPU intervention. The 64 MHz internal oscillator and PLL eliminate external crystals in most applications, while four 16-bit timers, two CCP modules, three ECCP modules (with PWM), and a CWG (Complementary Waveform Generator) provide flexible waveform synthesis for motor, lighting, and power-control loops. Typical applications include consumer appliances, IoT sensor nodes, touch-button human-machine interfaces, low-end motor control, LED lighting controllers, and functional-safety systems that benefit from the FuSa diagnostics. The combination of DMA + CLC + ADC2 allows a single 28-pin part to replace discrete logic and a small companion MCU in cost-sensitive designs. Design considerations: ensure the SSOP-28 land pattern follows IPC-7351 nominal density, place a 100 nF decoupling cap within 2 mm of each VDD pin, and reserve the MCLR pin through a 10 kohm pull-up for in-circuit serial programming (ICSP). The -I/SS variant operates from -40C to +85C; use the -E/SS extended grade for -40C to +125C automotive or industrial environments.

Key differentiating features include the integrated CAN 2.0B module with dedicated masks and filters, a 12-bit differential ADC2 with hardware CVD for robust touch and proximity sensing, DMA that moves data between peripherals and memory without CPU intervention, a 5-bit DAC, four 16-bit timers, four CLC blocks, and Microchip's eXtreme Low Power (XLP) technology that drops the device into nanoWatt sleep with full RAM retention. The UQFN-28 (6x6 mm) package with thermal pad supports compact automotive PCB layouts while keeping the die thermally bonded to the board. Typical applications include CAN-connected automotive body and chassis nodes (lighting, HVAC, sensor clusters), industrial CAN-bus sensors and actuators, capacitive touch user interfaces, low-power battery-powered metering with periodic wake, and any 8-bit node requiring deterministic analog sampling and protocol bridging. The combination of CAN, ADC2/CVD, DMA, and CLC means that one PIC18K83 device can replace a discrete MCU plus external ADC plus logic IC, reducing BOM and PCB area. When designing with the PIC18F25K83-E/MX, ensure the UQFN exposed pad is soldered to a sufficient copper pour for thermal and electrical grounding, place the two decoupling capacitors (100 nF and a bulk 1-10 uF) within 3 mm of VDD/VSS pairs, and verify the CAN bus termination and biasing network against ISO 11898-1. Engineers migrating from earlier PIC18 K-series parts must confirm that the new ADC2 register map and CIP blocks are handled by the latest MPLAB X IDE and XC8 compiler to take advantage of the hardware-accelerated touch and math libraries.

PIC18F25K83-E/SO - 8-Bit 64MHz 32KB Flash MCU | Microchip
PIC18F25K83-E/SO

PIC18F25K83-E/SO - 8-Bit 64MHz 32KB Flash MCU | Microchip

The Microchip PIC18F25K83-E/SO is an 8-bit PIC microcontroller from the PIC18(L)F25/26K83 family featuring CAN technology, a 12-bit ADC with Computation (ADC2), and 32KB of Flash program memory. The device runs at up to 64MHz and is housed in a 28-pin SOIC wide-body package. The "-E" temperature grade denotes an extended automotive temperature range of -40C to +125C, and the "/SO" suffix identifies the 28-SOIC (SOIC-28 wide, 7.50mm body width) package. A microcontroller (MCU) is a single-chip computer containing a processor core, program memory (Flash), data memory (RAM), and a rich set of peripheral interfaces (ADC, timers, communication ports, GPIO). The PIC18 family is built on an enhanced Harvard RISC architecture with a modified 16-bit instruction word; the "18K" designation refers to the K83 sub-family that integrates CAN, ADC2 (computation engine with averaging, oversampling, and CVD capacitive touch), and Microchip's eXtreme Low Power (XLP) technology. The PIC18F25K83 sits within the broader taxonomy: MCU -> 8-bit MCU -> PIC microcontroller -> PIC18 family -> PIC18F2xK83 sub-family. Key features include 32KB (16K x 16) Flash, 2KB RAM, 1KB EEPROM, a 12-bit differential ADC2 with up to 100 channels of capacitive touch sensing via CVD, a CAN 2.0B controller, multiple UART/SPI/I2C peripherals, a 16-bit CRC/Scan module for functional safety, and XLP nanoWatt sleep currents below 50 nA. The 64MHz internal oscillator and 4x PLL deliver 16 MIPS of CPU throughput. The 12-bit ADC2 is the headline differentiator: it performs automatic Capacitive Voltage Divider scans for mTouch touch buttons, sliders, and proximity sensors without CPU intervention, and supports hardware oversampling/averaging for higher effective resolution. Combined with the 16-bit CRC peripheral and memory BIST support, the K83 series is qualified for IEC 61508 / ISO 26262 functional-safety applications. Typical applications include automotive body and HVAC controllers, CAN node peripherals, capacitive touch user interfaces, industrial sensor transmitters, low-power IoT edge nodes, and functional-safety subsystems. The wide temperature grade makes it suitable for under-hood and chassis modules. When designing with this device, allocate one of the 28 SOIC pins for MCLR (reset), ensure adequate decoupling on VDD/AVDD/VBAT, and consult the ADC2 CVD tuning guide for noise-free capacitive touch channels. The "E" temperature grade requires derating for thermal resistance of the 28-SOIC at 1oz 4-layer PCB copper.

PIC18F25K83-E/SP

PIC18F25K83-E/SP - 8-bit 64MHz 32KB Flash MCU w/ CAN | Microchip

The Microchip PIC18F25K83-E/SP is an 8-bit PIC18 microcontroller with XLP low-power technology and Functional Safety (FuSa) support, offering 64 MHz CPU performance, 32 KB Flash, 2 KB RAM, and integrated CAN bus technology in a 28-pin SPDIP through-hole package. It belongs to the PIC18(L)F25/26K83 family of 28-pin low-power, high-performance MCUs. An 8-bit microcontroller (MCU) is a single-chip computer built around an 8-bit data path, designed for embedded control tasks such as sensor reading, motor driving, and protocol bridging. Microcontrollers sit within the broader hierarchy of microprocessors -> computing ICs -> integrated circuits -> semiconductors, and the PIC18 family is Microchip's mainstream high-performance 8-bit line, upgraded from the baseline PIC16 architecture with a 16-bit instruction word and linear memory addressing. Key features of this device include a 12-bit ADC with Computation (ADC2) that automates Capacitive Voltage Divider (CVD) techniques for advanced touch sensing, averaging, filtering, and oversampling; a CAN 2.0B module for vehicle or industrial networking; multiple Core Independent Peripherals (CIPs) that offload tasks from the CPU; and XLP technology for sleep currents in the nanoamp range. The 28-SPDIP package is the most repair-friendly through-hole option for prototype and industrial designs. The architecture pairs a 16-bit instruction word with an 8-bit data path, supporting up to 64 MHz operation from an internal oscillator, plus a hardware multiplier and C-optimized compiler support via MPLAB XC8. CIPs include Complementary Waveform Generator (CWG), Configurable Logic Cell (CLC), and multiple PWM/SCCP/MCCP modules. Together these allow the MCU to handle capacitive touch, motor control, and CAN communication largely without CPU intervention. Typical applications include CAN-connected automotive body controllers, industrial sensor nodes, capacitive-touch user interfaces, low-power battery monitors, and small motor-control subsystems where 32 KB Flash and 2 KB RAM are sufficient. The Extended (-E) temperature grade supports -40 C to +125 C operation for harsh environments. When designing with this part, route the CAN bus with a 120-ohm twisted pair and use an external CAN transceiver such as the MCP2562; do not rely on the internal CAN module to drive the bus directly. For capacitive touch, follow the CVD layout guidelines in the datasheet and dedicate a ground ring around each electrode for noise immunity. This page synthesizes verified distributor pricing, drop-in compatible alternatives from the same PIC18 K-series family, and practical design notes beyond the manufacturer datasheet to support both new design and second-source qualification.

PIC18F25K83-E/SS - 64MHz 8-bit MCU, 32KB Flash, CAN, 28-SSOP | Microchip
PIC18F25K83-E/SS

PIC18F25K83-E/SS - 64MHz 8-bit MCU, 32KB Flash, CAN, 28-SSOP | Microchip

The Microchip Technology PIC18F25K83-E/SS is a 64 MHz 8-bit PIC18 microcontroller with 32 KB Flash, 2 KB RAM, and 1 KB EEPROM in a 28-pin SSOP package, integrating CAN technology and a 12-bit ADC with Computation (ADC²) for advanced touch sensing. The '-E' suffix denotes the extended industrial temperature grade of -40 °C to +125 °C, while the '/SS' suffix designates the 28-pin SSOP package, and the part belongs to the PIC18F25K83 sub-family alongside the PIC18F26K83, PIC18F45K83, and PIC18F46K83 variants. A PIC18F-series 8-bit MCU is a CISC/RISC hybrid microcontroller built around the PIC Harvard architecture, enhanced instruction set, and Core Independent Peripherals (CIPs). It sits in the hierarchy: PIC18F -> 8-bit PIC MCU -> PIC microcontroller -> microcontroller -> embedded computing. The K83 generation specifically adds an integrated CAN module (CAN FD capable), a 12-bit differential ADC² with Capacitive Voltage Divider (CVD) hardware, and vectored interrupt controller with fixed latency for deterministic real-time response. Key features include a maximum CPU clock of 64 MHz (16 MIPS), 25 general-purpose I/O pins, an 8-channel 12-bit ADC² with hardware oversampling and CVD for capacitive touch, one CAN FD module, one I²C, two SPI/I²S, two UART modules, a 5-bit DAC, and four 16-bit timers. Power-saving features include nanoWatt XLP technology with typical idle current under 1 µA, sleep current under 100 nA, and an operating voltage range of 2.3 V to 5.5 V supporting both 3.3 V and 5 V rails. The PIC18F25K83 family combines Core Independent Peripherals with a CAN bus interface, allowing offloading of touch sensing, signal conditioning, and communication tasks from the CPU. Hardware CVD automates capacitive touch measurements, the DMA-capable ADC² performs averaging and thresholding autonomously, and CIPs such as the CWG, NCO, and PWM modules allow motor control and waveform generation without CPU intervention, making the K83 well suited for real-time industrial and automotive body-control designs. Typical applications include capacitive touch human-machine interfaces, CAN node industrial controllers, automotive body and lighting modules, sensor hub platforms, low-power IoT edge nodes, and small motor or fan control subsystems. Designers should pick this part when they need CAN connectivity plus integrated touch in a compact SSOP footprint. A key design consideration is decoupling: place 100 nF and 1 µF ceramic capacitors as close as possible to VDD/AVDD pins, route the 32.768 kHz crystal traces short and guarded, and keep the CAN bus 120 Ω termination accurate to maintain signal integrity on industrial networks. The 28-SSOP package also requires thermal relief on the PCB pad for hand rework. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, delivering engineering value beyond the standalone 28-pin 8-bit MCU documentation.
