PIC18LF2610-I/SO 概要
An 8-bit microcontroller (microcontroller) is a single-chip computer containing a CPU core, Flash program memory, RAM, non-volatile EEPROM, and a rich set of peripherals (timers, ADC, communication interfaces) integrated on one die. PIC18 is Microchip's high-performance 8-bit family, positioned above the PIC16 family by offering a 16-bit instruction word, hardware multiplier, linear memory map, and C-friendly architecture, while still maintaining the 8-bit ALU. Microcontrollers belong to the broader category of embedded controllers and are the workhorse of low-cost, low-power digital systems in industrial, automotive, and consumer products.
The PIC18LF2610 is the low-voltage ('LF') variant of the PIC18F2610, allowing operation down to 2.0 V (versus 4.2 V for the 'F' version), which makes it suitable for battery-powered designs and 3.3 V systems. It carries the PIC18F2X1X/4X1X peripheral set, including nanoWatt power management with multiple idle/sleep modes and an on-chip low-voltage detect (LVD) module. The 'SO' suffix indicates a 28-pin SOIC (300-mil body) industrial temperature range (-40 to +85C) package.
Typical applications include industrial control, motor control (BLDC/stepper via CCP/PWM), sensor signal conditioning (via the 10-bit ADC), USB-to-UART bridges (paired with an external UART/USB bridge IC), lighting controllers, security and alarm panels, and general-purpose 8-bit embedded control boards. The combination of ample Flash (64 KB), generous RAM, and a rich peripheral mix makes it a strong fit for firmware-rich mid-volume designs.
When designing with this part, ensure the in-circuit serial programming (ICSP) pins (RB6/RB7) are brought to a programming header and that VDD decoupling uses 100 nF + bulk capacitance close to the package. Choose the 'LF' variant explicitly when the supply rail is below 4.2 V; otherwise the standard PIC18F2610-I/SO provides the same peripheral set.

主な用途
PIC18LF2610-I/SO の用途: 6 件s: Industrial Motor Control (BLDC / Stepper), Sensor Signal Conditioning Front End, Lighting Controller (DALI / DMX / PWM Driver), Security and Alarm Panel, General-Purpose 8-bit Embedded Control Board, Battery-Operated Handheld Meter.
Industrial Motor Control (BLDC / Stepper)
The PIC18LF2610-I/SO is well suited to industrial motor control because its ECCP module delivers hardware PWM up to 10-bit resolution at 40 MHz (10 MIPS), and its 10-bit A/D with up to 11 channels can sample back-EMF or current-shunt feedback for closed-loop commutation. With 64 KB Flash and 3968-byte RAM, it has room for sensorless BLDC or stepper acceleration profiles plus UART diagnostics. The wide 2.0-5.5 V supply lets it run directly from a 24 V->3.3 V step-down in industrial cabinets. The 28-SOIC footprint provides a small board area for inline motor drivers where the MCU sits next to the FET gate-driver.
おすすめ
Sensor Signal Conditioning Front End
The PIC18LF2610-I/SO fits sensor-conditioning front ends for thermocouple, RTD, bridge and strain-gauge applications because its 10-bit A/D with 11 input channels can multiplex several sensors through one MCU, and the two on-chip analog comparators enable window comparators for alarm thresholds. The 3968-byte RAM supports circular DSP buffers for moving-average filtering, while the MSSP (SPI/I2C) can drive an external DAC or EEPROM for calibration data. Operating down to 2.0 V, the part is ideal for 2xAA-powered handheld meters where the standard F variant would not start. Engineers can drop the firmware into PIC18F2610-I/SO when supply exceeds 4.2 V.
おすすめ
Lighting Controller (DALI / DMX / PWM Driver)
The PIC18LF2610-I/SO is a strong fit for digital lighting controllers (DALI, DMX-512, 0-10 V dimming) because its ECCP module provides PWM at frequencies and resolutions ideal for dim-to-warm or RGBW LED channels, and the USART implements DMX-512 or DALI hardware protocol layers. The 64 KB Flash is more than adequate for color-mixing firmware, ramp tables, and remote commands. The 28-SOIC footprint lets the MCU sit inline with the LED driver PCB. The LF supply range allows direct operation from a 3.3 V rail coming off a buck converter downstream of the AC-DC stage.
おすすめ
Security and Alarm Panel
The PIC18LF2610-I/SO is widely used in security/alarm panels because its 25 I/O pins can scan a 4x4 keypad matrix, drive a 16-character LCD via the MSSP/SPI, and monitor multiple zones (PIR, door contact, glass-break) through the 10-bit A/D and comparators. The 64 KB Flash is sufficient for event logging, while 3968-byte RAM handles real-time zone state. The 2.0-5.5 V LF range allows backup-battery (3.6 V LiSOCl2) operation during AC loss, with nanoWatt sleep dropping consumption below 100 uA for multi-year battery life.
おすすめ
General-Purpose 8-bit Embedded Control Board
The PIC18LF2610-I/SO is a flexible general-purpose 8-bit control board MCU, suitable for educational kits, hobby platforms, and mid-volume OEM controllers. Its peripheral mix (1 USART, 1 MSSP SPI/I2C, 2 CCP/ECCP, 2 comparators, 11-channel 10-bit A/D) covers most UART-to-I2C bridges, sensor hubs, and small PLCs. With 64 KB Flash it can run a USB-to-UART converter firmware stack. The 28-SOIC package is widely accepted on through-hole adapter PCBs and is the de-facto 8-bit training and prototyping footprint.
おすすめ
Battery-Operated Handheld Meter
The PIC18LF2610-I/SO is well matched to battery-operated handheld meters (digital multimeters, environmental loggers, portable gas detectors) because the 'LF' 2.0 V minimum supply keeps the part running down to a nearly-drained 2xAA alkaline or single LiSOCl2 primary cell, while the nanoWatt sleep modes drop current to microamps. Its 10-bit A/D handles battery voltage and sensor readings; the ECCP can drive an LCD charge pump or piezoelectric buzzer. The 28-SOIC compact 7.5 mm body saves board area in pocket-sized form factors.

設計ノート
Place a 100 nF decoupling capacitor as close as possible to each VDD/AVSS pair (pins 19/28 on 28-SOIC). Add a bulk 10 uF tantalum or aluminum-polymer on the 3.3 V rail feeding the MCU to handle ECCP PWM inrush. The LF variant tolerates supply down to 2.0 V, but if you run close to brown-out, set the BOR (brown-out reset) voltage to the lowest acceptable level to maximize battery life. Source: Microchip DS39626G, Section 2 (Electrical Characteristics).
Always bring out the ICSP pins (RB6/PGC = pin 26, RB7/PGD = pin 27) to a 5-pin or 6-pin programming header. Microchip recommends a 100-mil spaced 2x3 or single-row header for ICD/PICkit compatibility. Add MCLR pull-up (typically 10 kohm) and route the MCLR trace away from high-frequency PWM lines to avoid spurious resets. Source: Microchip application note TB087 (ICSP layout recommendations).
Do not assume PIC18LF2610 and PIC18F2610 are interchangeable at low VDD - the LF variant is required below 4.2 V. Also note: the LF variant still requires the configuration bits CONFIG1L (e.g., IESO, FCMEN) to be correctly set; an unprogrammed fresh device has LVP (low-voltage programming) enabled by default, which can interfere with RB5 if used as general I/O. Estimated: typical idle current for LF part at 3.3 V, 1 MHz is ~50 uA (datasheet figure).
Keep analog input traces (AN0-AN12) short and away from PWM and oscillator traces. Use a separate analog ground (AVSS, pin 28) tied to VSS at a single point. Add a 100 nF + 10 uF decoupling pair on AVSS/VDD if the 10-bit A/D drives ADC precision-critical sensors. Estimated: with 1.5 kohm source impedance, 12 TAD acquisition time gives ~10-bit accuracy at 40 MHz.
For the 28-SOIC (0.295 in / 7.50 mm body), the recommended land pattern follows JEDEC SOIC-28 standard: pads ~0.05 in wide x 0.085 in long with 0.050 in pitch. Use a four-layer PCB with a dedicated ground plane directly under the MCU, and route VDD power as a wide (>=20 mil) trace or small pour. Place the 40 MHz crystal (if used) within 0.25 in of OSC1/OSC2 with short traces and a ground guard ring.
コンプライアンス情報
RoHS compliant per Microchip product page. Not AEC-Q100 qualified (use PIC18F26K80 or similar for automotive). LF variant indicates low-voltage operation 2.0-5.5 V (vs F variant 4.2-5.5 V).
