PIC16F610-I/SL Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash, SRAM, EEPROM), peripherals (timers, ADC, comparators), and I/O on one die. Within the broader taxonomy, the PIC16F610 belongs to the 8-bit microcontroller family -> RISC microcontroller -> CMOS MCU -> semiconductor. Mid-range PIC16 parts use a 14-bit instruction word and a 35-instruction RISC core, delivering predictable 200 ns instruction execution at 20 MHz while keeping the programming model simple.
Key features include enhanced mid-range 14-bit core, 1.75 KB self-programmable Flash, 72-byte SRAM, internal 8 MHz and 31 kHz oscillators, 4-channel 8-bit ADC, 2 comparators, 1Γ 8-bit and 1Γ 16-bit timers, nanoWatt power management with sleep current below 1 Β΅A typical, and ICD debugging via two pins. Twelve general-purpose I/O pins support interrupt-on-change and weak pull-ups.
The PIC16F610 implements Microchip's enhanced mid-range 14-bit RISC architecture with single-cycle instruction execution except for program branches. The on-chip debug (ICD) and in-circuit serial programming (ICSP) interfaces share two pins, leaving the remaining pins for application use. Peripherals such as comparators and the ADC can be routed to device pins through the Peripheral Pin Select (PPS) mechanism, simplifying board routing for analog and mixed-signal designs.
Typical applications include low-power sensor nodes, battery-powered home appliances, LED lighting control, automotive body electronics (non-safety), small motor control, and consumer remote controls. The wide 2.0V-5.5V supply range supports both lithium battery and regulated 3.3V/5V rails, while nanoWatt modes allow multi-year coin-cell operation.
When designing with this device, allocate one pin pair for ICSP/ICD regardless of production intent - removing debug access early blocks field firmware updates. Place a 100 nF decoupling capacitor within 5 mm of VDD and a 10 Β΅F bulk capacitor near the supply entry, and keep the MCLR pull-up under 47 kΞ© to guarantee reset in noisy environments.

Typical Applications
PIC16F610-I/SL is suitable for 6 applications: Battery-Powered Sensor Node, LED Lighting Control, Home Appliance Control, Consumer Remote Control, Small DC Motor Control, Automotive Body Electronics (Non-Safety).
Battery-Powered Sensor Node
The PIC16F610-I/SL is well-suited to coin-cell or 2xAA sensor nodes because its nanoWatt sleep current drops below 1 Β΅A typical, allowing multi-year standby on a 220 mAh CR2032. The internal factory-calibrated 8 MHz oscillator eliminates an external crystal, while the 2.0-5.5 V supply range covers battery droop down to end-of-life voltage. The 4-channel 8-bit ADC handles temperature, light, or humidity sensors directly. Compared with PIC16F506, the PIC16F610 integrates the 8 MHz HFINTOSC and offers 72 bytes of RAM for modest protocol stacks, removing two external components and shrinking the BOM. Place the device in sleep between ADC conversions and wake via Watchdog Timer to maximize battery life in wireless sensor designs.
Recommended
LED Lighting Control
The PIC16F610-I/SL drives LED strings and RGB lighting through PWM channels and on-chip comparators, with the 16-bit timer providing flicker-free dimming resolution. Its 20 MHz CPU computes color-mixing profiles and DMX-style lighting protocols in real time, while the 12 GPIO pins can scan multiple switch inputs or rotary encoders without external logic. The wide 2.0-5.5 V supply range allows direct connection to 3.3 V or 5 V LED driver rails, simplifying power architecture. Compared with discrete 555-based LED dimmers, this part offers programmable curves, soft-start, and current limiting via the on-chip comparators all in a single 14-pin SOIC, enabling compact, low-cost architectural and signage lighting.
Recommended
Home Appliance Control
The PIC16F610-I/SL is widely deployed in white-goods control boards for washing machines, dishwashers, and microwave ovens, where it sequences motors, solenoids, relays, and user-interface keypads. The 14-pin SOIC footprint drops onto legacy boards designed for older PIC16C/F parts, while Flash-based program memory supports last-minute firmware changes via ICSP without re-spinning hardware. Its two on-chip comparators provide over-current detection for motor drivers, and the 16-bit timer captures tachometer pulses for RPM feedback. Compared with PIC16F505, this part offers 64% more Flash and an internal 8 MHz oscillator, cutting crystal cost and easing EMI compliance in motor-noise environments.
Recommended
Consumer Remote Control
The PIC16F610-I/SL fits IR remote controls because its nanoWatt sleep current (below 1 Β΅A typical) lets a single CR2032 last the shelf life of the remote. The on-chip comparators detect the IR demodulated signal without an external op-amp, and the 16-bit timer measures carrier frequency for protocol decoding (NEC, RC5, SIRC). Its 12 GPIO matrix-scan up to 64 keys using a 4Γ8 keypad, while Flash-based memory supports multi-protocol universal remotes. Compared with PIC12F parts, the PIC16F610 offers more Flash for protocol libraries and more RAM for buffer-based encoding algorithms in the same SOIC-14 footprint.
Recommended
Small DC Motor Control
The PIC16F610-I/SL drives small brushed DC motors and micro-steppers via PWM plus on-chip comparators for back-EMF sensing and current limiting. The 16-bit timer generates 20 kHz PWM above the audible band, while the 8-bit ADC reads current-sense amplifiers for closed-loop torque control. The wide supply range allows direct operation from 3-cell alkaline packs or 1S Li-ion, simplifying the power tree. Compared with discrete analog motor control, this part adds programmability for soft-start, stall detection, and adaptive braking without external op-amps or comparators, fitting hobby robotics, small appliances, and toys.
Recommended
Automotive Body Electronics (Non-Safety)
The PIC16F610-I/SL is used in non-safety automotive body modules such as interior lighting, seat controllers, and accessory switches, where 12 V battery transients are handled by an external regulator feeding the 2.0-5.5 V VDD. Its 8-bit ADC reads switch positions and analog sensors, while GPIO drives relays, LEDs, and LIN bus transceivers. Note that this -I/SL grade is rated -40C to +85C; for under-hood or AEC-Q100 environments, choose PIC16F610-E/SL (extended -40C to +125C) or an AEC-Q100-qualified part. Compared with PIC16C505, this Flash-based variant supports field firmware updates via ICSP, critical during a vehicle's service life.

Key Differentiators
- Integrated 8 MHz factory-calibrated internal oscillator (vs PIC16F506-I/SL)
- Larger SRAM for protocol stack buffering (vs PIC16F506-I/SL)
- Industrial -40Β°C to +85Β°C temperature grade for cost-optimized designs (vs PIC16F610-E/SL)
Design Notes
Place a 100 nF decoupling capacitor within 5 mm of the VDD pin and a 10 Β΅F bulk capacitor near the supply entry point. The PIC16F610's nanoWatt sleep current drops below 1 Β΅A typical only when all peripherals are disabled and the internal HFINTOSC is shut down; leaving an ADC channel active in sleep can raise Iq to 200-300 Β΅A. For battery life calculations, use the Microchip datasheet DS41267E Figure for Iq vs VDD at 25Β°C, not the headline 1 Β΅A spec which assumes optimal settings.
The MCLR pin (pin 4) is shared with RA3 and the programming voltage VPP; do not leave it floating in production. Use a 10 kΞ© pull-up to VDD and a 100 nF cap to ground to filter ESD transients. Attempting ICSP on a board without proper MCLR isolation (or with the pull-up above 47 kΞ©) results in programming failures that look like dead silicon but are actually reset-line noise.
ICSP and ICD share pins RA0 (ICSPDAT) and RA1 (ICSPCLK); if the application uses both pins as analog inputs, isolate them with 100 Ξ© series resistors or a 4.7 kΞ© pull-down so the in-circuit programmer can drive them without contention. Route ICSPCLK away from switching signals and oscillators to avoid debug-session lockups. The exposed SOIC-14 thermal pad is not present on this package, so no thermal copper pour is required beyond standard signal traces.
Compliance Information
RoHS and REACH compliant per Microchip product page; lead-free and halogen-free per DS41267E. Not AEC-Q100 qualified - choose PIC16F610-E/SL (extended temp) or an AEC-Q100 part for automotive designs.
