PIC18F27Q83T-I/SO 概要
An 8-bit microcontroller (MCU) is a microprocessor that processes data in 8-bit-wide chunks and integrates Flash, RAM, EEPROM, peripherals, and interrupt logic on a single die. The PIC18 family uses an enhanced Harvard RISC architecture with a 16-bit instruction word and an 8-bit data path; it sits in the hierarchy: 8-bit MCU -> microcontroller -> embedded processor -> semiconductor. The PIC18-Q83 series targets applications where Core Independent Peripherals (CIPs) offload timing-critical tasks from the CPU, lowering power and code complexity.
Key features include integrated CAN FD support, a 12-bit ADC with automatic averaging and threshold comparison, the Configurable Logic Cell (CLC) and Signal Measurement Timer (SMT) CIPs, and zero-cross detection. The device operates from 1.8V to 5.5V and offers nanopower technology with typical IDLE currents around 5 µA, allowing battery-friendly sleep modes.
Typical applications include automotive body and sensor nodes, industrial control, building automation, sensor conditioning, and low-cost CAN node endpoints. The 28-SOIC package is footprint-compatible with legacy PIC18F2xK80 and PIC18F2xK42 designs, simplifying migration.
When designing, ensure decoupling capacitors are placed within 3 mm of VDD/VSS, use proper CAN bus termination (120 Ω at each end), and follow the datasheet recommended trace geometry for the ADC analog inputs. The 'T' suffix indicates Tape & Reel packaging.

主な用途
PIC18F27Q83T-I/SO の用途: 6 件s: Automotive Body & Sensor Nodes, Industrial Sensor Conditioning & Control, Building Automation & HVAC Nodes, Low-Cost CAN Endpoint Modules, Battery-Powered IoT Edge Devices, Consumer Appliance Control Boards.
Automotive Body & Sensor Nodes
The PIC18F27Q83T-I/SO integrates a hardware CAN FD controller compliant with ISO 11898-1, making it ideal for automotive body and sensor nodes. With 128 KB Flash and 13 KB SRAM, the device can host a CANopen or J1939 stack alongside application firmware, while the 12-bit ADCC handles temperature, pressure, or position sensors with hardware averaging that frees CPU cycles. The 1.8V to 5.5V supply range allows direct connection to a 5V or 3.3V automotive bus, and nanopower Sleep reduces quiescent draw on always-on nodes. Designers pair it with the MCP2517FD external CAN FD controller only if high-speed CAN FD channels are needed; otherwise the internal module is sufficient.
おすすめ
Industrial Sensor Conditioning & Control
The 12-bit ADC with computation (ADCC) and on-chip 5/8-bit DAC make the PIC18F27Q83T-I/SO a natural fit for industrial sensor signal conditioning. The ADCC supports hardware averaging, oversampling, and threshold comparison, so an analog front end feeding a 4-20 mA loop or resistive bridge can be digitized with minimal CPU overhead. The SMT and CLC CIPs perform timing-critical measurement tasks in hardware, allowing the CPU to remain in IDLE for long periods - critical for energy-harvesting or battery-powered industrial nodes. The wide 1.8V to 5.5V supply allows direct interfacing with 24V industrial rails via a single LDO.
おすすめ
Building Automation & HVAC Nodes
Building automation nodes - thermostats, damper controllers, lighting keypads - benefit from the PIC18F27Q83T-I/SO's combination of 128 KB Flash, 13 KB SRAM, and multiple communication peripherals (UART, I2C, SPI). The 28-SOIC footprint fits compact wall-mount enclosures, and nanopower Sleep with wake-on-touch via the CLC allows battery-powered touch interfaces that wake only on user input. The hardware CWG and PWM channels drive LED dimmers and small triac gates without software bit-banging. With CAN FD on-board, multiple nodes can be networked over a robust differential backbone rather than daisy-chained UART.
おすすめ
Low-Cost CAN Endpoint Modules
When designing cost-sensitive CAN endpoint modules - simple sensor or actuator nodes that sit at the edge of a CAN network - the PIC18F27Q83T-I/SO provides a single-chip solution: the integrated CAN FD controller eliminates an external CAN ASIC, while the 12-bit ADCC handles analog sensor inputs directly. With 128 KB Flash it can support modest protocol stacks, and the 1 KB EEPROM allows node-ID and calibration storage without an external memory chip. The hardware CLC and NCO let designers implement custom bit-streams, PWM, or frequency synthesis without taxing the CPU. The 28-SOIC footprint is well-suited to hand-soldering prototypes.
おすすめ
Battery-Powered IoT Edge Devices
For battery-powered IoT edge devices the PIC18F27Q83T-I/SO offers nanopower Sleep with IDLE currents around 5 µA typical, and peripherals like the SMT, RTC, and CLC can run while the CPU is asleep to wake on real events. The 1.8V to 5.5V supply range permits direct operation from a single CR2032 or 2x AA cell stack without boost conversion. With 13 KB SRAM and 128 KB Flash, the MCU can run lightweight wireless stacks (custom or proprietary) over UART/SPI radios. The 28-SOIC package is footprint-compatible with hand-rework-friendly designs and supports industrial temperature range for outdoor deployments.
おすすめ
Consumer Appliance Control Boards
White goods and consumer appliances benefit from the PIC18F27Q83T-I/SO's integrated 12-bit ADC, multiple PWM channels, and small 28-SOIC footprint. The CIPs (CLC, NCO, CWG, DSM) handle appliance-specific tasks such as motor soft-start, triac zero-crossing, and tone generation in hardware, dramatically reducing firmware complexity and BOM cost. The 128 KB Flash hosts UI logic, fault diagnostics, and communication stacks, while 1 KB EEPROM stores user settings and error logs across power cycles. The wide supply range and industrial temperature grade ensure reliable operation in kitchen or laundry environments.

設計ノート
Place a 0.1 µF ceramic decoupling capacitor within 3 mm of each VDD/VSS pair (pins 8 and 20 on the SOIC-28). For noise-sensitive analog sampling, add a bulk 10 µF tantalum or aluminum-polymer cap at the board's main supply input. The PIC18F27Q83T-I/SO draws IDLE currents around 5 µA typical - ensure your LDO has low Iq or use the internal Sleep modes to extend battery life in IoT deployments.
Route the CAN FD differential pair (CANTX/CANRX) as a 120 Ω differential microstrip with matched length (±2 mm) and impedance-controlled to 120 Ω. Place the MCP2562FD transceiver adjacent to the MCU with the bus-side ESD protection (e.g., PESD1CAN) within 5 mm of the connector. Keep analog traces away from digital switching nodes; the ADCC channels are noise-sensitive and benefit from a guarded analog ground island.
Avoid floating digital inputs - unused I/O pins on the PIC18F27Q83T-I/SO must be configured as outputs or tied to VDD/VSS to prevent shoot-through and excess current. Do not operate VDD below 1.8V or above 5.5V; ADC accuracy degrades outside 2.3V to 5.5V. The 'T' suffix indicates Tape & Reel; confirm reel orientation against your pick-and-place feeder to avoid soldering mirrored parts onto the board.
Estimated: at maximum activity (64 MHz, all peripherals enabled, 3.3V supply), the PIC18F27Q83T-I/SO dissipates roughly 30 mW. The 28-SOIC package's thermal resistance θJA is approximately 80 C/W on a 2-layer FR-4 board, giving a junction-to-ambient rise of only 2.4 C - well within the 85 C industrial limit. For higher ambient temperatures, improve θJA by adding thermal vias under the exposed pad or upgrading to a 4-layer board.
