Key features of the PIC18F26Q43 include a 12-bit Analog-to-Digital Converter with Computation (ADCC) that automates capacitive voltage-divider (CVD) touch sensing, averaging, filtering, oversampling, and threshold comparison. A new 16-bit Pulse-Width Modulation (PWM) peripheral, multiple Core Independent Peripherals (CIPs), and configurable logic cells let sophisticated hardware behaviour be implemented without CPU intervention. The device also integrates a 5-bit DAC, comparators, configurable communications (UART/SPI/I2C), and a windowed watchdog timer for functional-safety-capable designs. Typical applications for the PIC18F26Q43-I/SP include capacitive touch user interfaces, LED lighting control, sensor hub nodes, motor and fan control, low-cost IoT edge nodes, and industrial automation controllers. Its 64 KB Flash, 4 KB SRAM, and rich peripheral set allow designers to consolidate what would otherwise require an external ADC plus logic into a single 28-pin through-hole part, simplifying layout and BOM. When designing with this MCU, reserve a 100 nF decoupling capacitor close to each VDD pin, configure the MCLR pin correctly for in-circuit serial programming (ICSP), and review the ADCC sequencing if capacitive touch performance is critical. The 28-SPDIP footprint also makes it an easy hand-solderable option for prototypes, education, and field-service replacements.

The 28-pin SOIC package offers 25 digital I/O pins, each with interrupt-on-change and weak pull-up, and supports ICSP (In-Circuit Serial Programming) plus ICD (In-Circuit Debugger) via the standard PGC/PGD pins. The wide operating voltage of 1.8V to 5.5V covers single-cell Li-ion and 5V industrial rails, and eXtreme Low Power (XLP) sleep modes reduce quiescent current below 100 nA for battery-powered sensor nodes. Typical applications include automotive body and comfort modules, CAN FD sensor nodes, industrial control with brushless DC motor drives, building automation, smart energy metering, and USB-to-CAN bridges. The combination of CAN FD with USB and high-resolution PWM is unusual at this price point and addresses compact automotive gateway designs. A key design tip is to allocate the CAN FD peripheral to pins RB2/RB3 via PPS (Peripheral Pin Select) and reserve the DMA controller for ADCC-to-memory transfers to free the CPU for protocol stack execution. Use the high-resolution PWM with NCO for fine-grained current control in switching power supplies.

PIC18 J-series devices sit in the PIC microcontroller family hierarchy as PIC -> PIC18 -> PIC18 J-series, designed for cost-sensitive applications that need higher memory density and peripheral flexibility than baseline PIC16 parts. The J-series is distinguished from K-series parts by its 2.0-3.6 V core supply and 5.5 V tolerant I/O, making it ideal for mixed-voltage systems. Key features include 128 KB (64K x 16) Flash program memory, 4 KB RAM, 12-bit A/D converter with up to 10 channels, two comparators, two CCP/ECCP modules, four 8/16-bit timers, hardware RTCC, two MSSP (SPI/I2C) ports, two enhanced USART modules, and a 10-bit DAC reference output. The deep-sleep mode current is in the hundreds of nanoamperes, while run-current is roughly a few mA per MHz, enabling years of battery life on coin cells. The PIC18F27J13-I/SS uses a modified Harvard RISC architecture with a 16-bit instruction word and 8-bit data path. Code is executed from Flash via a 2-stage pipeline that lets the next instruction pre-load while the current one executes, supporting the 12 MIPS throughput at 48 MHz. Peripherals are memory-mapped through SFRs and configured via PPS (Peripheral Pin Select) for flexible pin assignment. Typical applications include portable medical devices, low-power wireless sensor nodes, USB HID peripherals (with the PIC18 USB J-series siblings), consumer appliances, smart meters, and industrial control boards. The wide memory and deep-sleep capability suit applications that wake occasionally to log or transmit data. When designing with this device, ensure the core VDD stays within 2.0 V to 3.6 V while the I/O pins can be pulled up to 5.5 V for mixed-voltage buses. Decouple VDD/VSS with 100 nF ceramic caps close to each pin pair, and configure unused I/O as outputs to minimize sleep current. Use the PPS system to remap peripherals to alternate pins if board layout constraints change. This page synthesizes distributor pricing, drop-in same-package alternatives, and engineering design notes not found in the manufacturer datasheet alone, giving procurement and design engineers a single reference for sourcing and implementing the PIC18F27J13-I/SS.

PIC18F27J13T-I/ML

PIC18F27J13T-I/ML - 8-Bit 48MHz 128KB Flash MCU | Microchip

The Microchip PIC18F27J13T-I/ML is an 8-bit PIC microcontroller in the PIC18 J-series family, delivering 48 MIPS performance at 48 MHz with 128 KB of Flash program memory, packaged in a 28-pin QFN (6x6 mm) surface-mount form factor. The T-suffix denotes Tape-and-Reel packaging and the ML suffix indicates the QFN package; the operating temperature grade is industrial -40C to +85C. The '27' prefix means 28 pins, the 'F' indicates Flash memory, and 'J13' places the device in the nanoWatt XLP low-power J-series. A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and programmable I/O peripherals. The PIC18 family uses an enhanced 8-bit RISC Harvard architecture with 16-bit-wide instructions, enabling most instructions to execute in a single cycle. PIC MCUs target cost-sensitive embedded applications where deterministic real-time response, low power consumption, and ease of development matter more than raw computational throughput, and they sit in the broader category of 8-bit microcontrollers alongside 8051 and AVR devices. Key features of this device include 128 KB self-programmable Flash, 3.8 KB RAM, 8-channel 10-bit ADC, two USART modules, two SPI and two I2C peripherals, and up to 22 digital I/O pins. Microchip's nanoWatt XLP technology adds a deep-sleep mode drawing nanoamp-level current, making the device well suited to battery-powered designs. The integrated RTCC and CTMU peripherals reduce external component count for touch and timing applications. Architecture-wise the PIC18F27J13 uses an internal PLL to derive a 48 MHz system clock from a wide range of external crystals or internal oscillator sources. The 28-pin QFN package leaves I/O count intentionally limited but offers an exceptionally small 6x6 mm footprint with an exposed thermal pad, while keeping all analog and digital peripherals accessible from the remaining GPIO. Typical applications include consumer electronics control boards, low-power IoT sensor nodes, battery-powered handheld instruments, USB peripherals with on-chip transceivers, home automation gateways, and educational/development boards. Designers often choose this MCU when they need more Flash than the PIC18F25 series but fewer pins than the 44-pin PIC18F46 variants, with nanoWatt XLP enabling years of operation from a coin cell. For new designs, verify the latest silicon revision in the datasheet before commit because the PIC18F27J13 family has multiple silicon revs. Ensure decoupling capacitors are placed as close as possible to VDD/VDDCORE pins and that the QFN thermal pad is soldered to a properly sized ground copper pour for thermal dissipation. This page synthesizes distributor pricing, drop-in cross references, and practical design notes that go beyond what appears in any single manufacturer document, giving engineers and procurement teams a single source for technical and commercial decisions about this MCU.
