PIC18F2610T-I/SO 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, volatile data memory, and multiple peripherals on a single silicon die. The PIC18 family belongs to the broader 8-bit MCU category, occupying the lower tier of the embedded processing hierarchy: microcontroller -> microprocessor -> semiconductor device. Its strength is real-time deterministic control with low power consumption (nanoWatt Technology), trading raw compute throughput for predictable interrupt response and rich peripheral integration.
Key differentiating specifications of the PIC18F2610T-I/SO include 25 digital I/O pins, hardware USART, MSSP (SPI/I2C), and enhanced flash program memory (32K x 16 organization). The integrated 10-bit A/D converter, capture/compare PWM modules, and nanoWatt power management make this part adaptable to a wide range of cost-sensitive industrial, consumer, and automotive subsystems.
Architecturally the PIC18F2610T-I/SO leverages an enhanced Harvard architecture with a 16-bit instruction word (vs the 14-bit PIC16 baseline), allowing 32K instruction words of addressing per 64 KB of flash and a linear program counter space. The RISC-style instruction set delivers most instructions in one instruction cycle (4 oscillator clocks at 40 MHz = 100 ns), supporting tight timing loops without an external DSP or ARM-class core.
Typical applications include industrial sensor conditioning, building automation controllers, low-end consumer appliances, automotive body and lighting modules, USB-less embedded human-machine interfaces, and small motor-control loops. The 28-SOIC footprint, broad industrial temperature range (-40C to +85C for the I-suffix), and stable supply make it a drop-in for designs already laid out around PIC18F mid-range pinouts.
When designing with this MCU, provide a stable 5 V rail and decouple VDD/AVDD/VSS with 100 nF + 10 uF ceramic capacitors placed close to the package pins. ISP via ICSP requires the PGC/PGD lines to be reserved in the schematic even if unused in production - retro-fitting an in-system programming connector later forces a board revision.

主な用途
PIC18F2610T-I/SO の用途: 6 件s: Industrial Sensor Conditioning Hub, Building Automation Controller, Low-End Consumer Appliance Control, Automotive Body and Lighting Module, USB-less Embedded HMI Front Panel, Small Motor Control Loop (Brushed DC / Stepper).
Industrial Sensor Conditioning Hub
The PIC18F2610T-I/SO fits industrial sensor hubs because its integrated 10-bit A/D converter samples up to 25 analog channels at 100 ksps, which is sufficient for the analog signal-chain front ends in PLCs and 4-20 mA sensor transmitters. Combined with the 40 MHz core clock yielding 10 MIPS, it can simultaneously digitize thermocouples, RTDs, or pressure sensors while running the Modbus RTU protocol over the integrated USART. The 4.2-5.5 V supply range is compatible with 24 V industrial rails after downstream regulation. NanoWatt Technology reduces standby current to microamperes, supporting battery-backed fault loggers that must survive months without external power. Compared with discrete A/D + CPLD designs, this single-chip approach cuts BOM cost while keeping the firmware path upgradeable through ICSP without removing the module from the panel.
おすすめ
Building Automation Controller
For HVAC and lighting controllers, the PIC18F2610T-I/SO provides 25 I/O lines that are enough to drive 8-12 relay outputs, 4-6 keypad rows, and 4-8 sensor inputs without external mux chips. The 64 KB Flash holds BACnet or KNX-style proprietary protocol stacks plus HVAC state-machine firmware, and the MSSP peripheral implements SPI/I2C master control of dimmers and digital temperature sensors like the MCP9808. Wide industrial temperature range (-40C to +85C) allows installation in unheated utility closets. The 5 V supply voltage aligns directly with analog HVAC actuator drivers so no level shifter is needed. Compared with PIC16F877 legacy designs, the PIC18F2610 doubles code space and adds a hardware multiplier so PID loops can run with full precision instead of lookup tables.
おすすめ
Low-End Consumer Appliance Control
Microwave ovens, dishwashers, washing machines, and small kitchen appliances rely on 5 V 8-bit MCUs to coordinate timing, motor sequencing, switch-matrix keypads, and 7-segment LCDs. PIC18F2610T-I/SO's 64 KB Flash and 3.8 KB RAM fit appliance firmware with margin for safety-watchdog logic, fault logging, and self-test routines. The built-in PWM captures the 7-segment multiplexing without external drivers, and the USART talks to the front-panel microcontroller sharing LED patterns. At 100 ns instruction cycle, the core reacts to button press debouncing in real time, critical for ergonomic user experience. Compared with PIC16F devices, this part provides a hardware multiplier so RPM estimation can be done by direct integer math instead of pre-computed tables stored in flash.
おすすめ
Automotive Body and Lighting Module
Within automotive body-electronics (interior lighting, mirror controls, seat memory modules), the PIC18F2610T-I/SO functions as a 5 V-tolerant, 40 MHz switch and dimmer controller. Its PWM modules (CCP) drive LED current-regulator FETs and H-bridge motors at refresh rates beyond 200 Hz, eliminating visible flicker in cabin lighting. 25 I/O lines coordinate CAN-side wakeup signals, LIN slave interface (via USART), and interior cockpit buttons. While the I-suffix part is rated to +85C, the PIC18F2610-E/SO variant extends headroom to +125C for under-hood applications. Compared with R8C and RL78 competitors, the PIC18 ecosystem's MPLAB X IDE and XC8 toolchain shorten firmware development time for tier-1 OEMs.
おすすめ
USB-less Embedded HMI Front Panel
Operator-interface panels for industrial machines use the PIC18F2610T-I/SO to scan 4x4 keypads, drive 16x2 character LCDs via MSSP, and stream ASCII menu updates through the USART to a host controller. The 64 KB Flash supports multi-language font tables plus full state menu firmware without an external memory. 40 MHz CPU throughput keeps the LCD refresh at the recommended 60 Hz even during heavy interrupt load from keypad scanning. The 28-SOIC footprint fits behind the LCD PCB inside the panel's housing footprint. Compared with graphical-TFT designs that use STM32, this part lets engineers deliver a cost-sensitive 5V HMI on existing PIC18 layouts without retooling firmware.
おすすめ
Small Motor Control Loop (Brushed DC / Stepper)
Closed-loop brushed DC motor and stepper drivers use the PIC18F2610T-I/SO for trapezoidal commutation, current-limit detection, and PI speed regulation via the on-chip CCP/PWM peripherals running at up to 40 MHz. The 10-bit A/D samples back-EMF and shunt current at rates adequate for sub-kilowatt motor control, and the 64 KB Flash accommodates state tables for trapezoidal commutation plus encoderless startup firmware. The 5 V supply fits directly to small motor FET pre-driver logic. Compared with dedicated motor-control ICs, the PIC18 approach lets the same firmware drop into multiple motor form-factors by changing look-up tables.

設計ノート
Decouple VDD (pin 20) and VSS (pin 19) with a 100 nF X7R ceramic in parallel with a 10 uF X5R ceramic placed within 5 mm of the package body. Forboard layouts with multiple ICs, route a separate analog ground (AVSS) only if the PIC18F2610 variant used exposes it on this pinout (the 28-SOIC SO package ties AVSS to VSS internally). Bulk capacitance on the 5 V regulator should be 100 uF or larger, sized to support the high pin-toggle transients when parallel ports switch simultaneously.
Reserve the RB6 (PGC) and RB7 (PGD) lines in the schematic even if not used in production; routing them to a 2x5 header with MCLR/VPP enables in-circuit programming via MPLAB PICkit 5 without a board revision. Place the crystal load capacitors (typically 15-22 pF NPO/C0G) within 5 mm of OSC1/OSC2 pins, with the oscillator traces guarded by an analog ground island to reduce jitter from switching noise on adjacent lines.
The 40 MHz core generates 10 MIPS, which can produce fast edges on PORTB digital outputs - if driving long PCB traces, place a 22-100 ohm series resistor at the driver to dampen reflections. On MSSP (SPI/I2C) lines, add 4.7 kohm pull-ups on I2C SDA/SCL and keep SPI traces under 50 mm to avoid ringing at 10 MHz. For RS-485 communications via USART, use a slow slew-rate transceiver (e.g., MAX3485) instead of high-speed parts to keep EMI under CISPR 11/22 limits.
Estimated: the 64 KB Flash writes via ICSP take approximately 4-6 seconds per page with PICkit 5 - do not size the production code beyond 95% of available space or page-write verification failures can occur at extreme temperatures. The MCLR reset pin needs a 10 kohm pull-up to VDD; floating MCLR is the most common cause of intermittent start-up behavior on PIC18 boards in the field. If you migrate from PIC18F2610 to PIC18F2620 firmware, validate that stack pointer initialization matches (both use 31-level hardware stack).
コンプライアンス情報
RoHS and lead-free status per the Microchip product page. The I-suffix variant is industrial grade (-40C to +85C); automotive AEC-Q100 qualification is not standard on this part - select the PIC18F2620-I/SO automotive version if AEC-Q100 is mandatory.
