PIC16LC711-04/P Overview
A PIC (Peripheral Interface Controller) microcontroller is a Harvard-architecture RISC device that separates program and data memory paths to allow simultaneous instruction fetch and operand access, increasing throughput relative to von Neumann CISC devices. The PIC16C71X family is positioned in Microchip's mid-range tier, offering 14-bit instruction words, a 35-instruction opcode set, an 8-level hardware stack, and integrated ADC peripherals - the PIC16LC711 specifically targets battery-powered and low-voltage commercial applications where the standard PIC16C711's 4.5-6.0 V range is too restrictive.
Key features include 13 digital I/O pins, 4 analog input channels multiplexed to an 8-bit successive-approximation ADC with 25 us conversion time, power-on reset, watchdog timer with on-chip RC oscillator, power-saving SLEEP mode, and in-circuit serial programming (ICSP) capability via RB6/RB7. The LC variant's wider 2.5 V minimum operating voltage enables direct connection to 3.3 V logic rails without level shifting, while its lower quiescent current extends battery life in sleep-dominant duty cycles. The 18-pin PDIP package is the most user-friendly form factor for prototype, hobby, education, and legacy through-hole PCB designs.
Typical applications include battery-powered sensor nodes, low-cost consumer white goods, educational trainer boards, automotive interior accessories (non-safety), industrial control panels with analog front-ends, and legacy embedded system retrofits. The 8-bit ADC simplifies designs that require analog sensing without adding a dedicated ADC IC. Designers should note that the OTP variant cannot be reprogrammed in-circuit - the windowed UV-erasable PIC16LW711 is the development counterpart. When migrating designs, the 18-pin PDIP footprint is shared across the PIC16C710, PIC16C71, PIC16C711, PIC16C715 and PIC16LC family members.
Design considerations: ensure the oscillator start-up time is observed at power-on, especially with low-frequency crystals. Place a 0.1 uF decoupling capacitor within 5 mm of VDD, and reserve pin RB0/INT for an external interrupt source if wake-on-event functionality is required. The device is rated for commercial (0C to +70C) operating temperature; for industrial or automotive temperature grades, the PIC16LC711-04I variant is required.

Typical Applications
PIC16LC711-04/P is suitable for 6 applications: Battery-Powered Sensor Node, Educational Microcontroller Trainer, Industrial Control Panel with Analog Inputs, Consumer White Goods Controller, Automotive Interior Accessory (Non-Safety), Legacy Embedded System Retrofit.
Battery-Powered Sensor Node
The PIC16LC711-04/P's extended 2.5 V minimum VDD and integrated SLEEP mode make it ideal for battery-powered sensor nodes that duty-cycle between active ADC conversion and sleep states. With 68 bytes RAM and 1.75 KB OTP, the device can run a temperature/humidity sampling loop, store calibration constants, and wake on watchdog overflow. Its 4-channel 8-bit ADC reads thermistor or sensor outputs directly without an external ADC IC, reducing BOM cost. Compared with a 5 V PIC16C711, the LC variant extends battery life by enabling direct 3 V lithium or 2x AA alkaline operation without boost regulation. The 18-pin PDIP package simplifies hand-soldered prototypes and low-volume production.
Recommended
Educational Microcontroller Trainer
The PIC16LC711-04/P in 18-pin PDIP is widely used in university and hobbyist microcontroller courses because the through-hole package is breadboard-friendly and the PIC16C71X instruction set is well-documented in textbooks. With 1.75 KB OTP, 13 I/O pins, and integrated ADC, students can build projects ranging from LED blinking to analog sensor interfacing within a single semester. The 4 MHz oscillator is forgiving for timing-accuracy exercises, and ICSP via RB6/RB7 enables iterative programming without removing the chip. Wide availability at $1.55-$2.45 per unit keeps student lab kits affordable.
Recommended
Industrial Control Panel with Analog Inputs
In industrial control panels requiring front-panel potentiometer reading or 4-20 mA loop monitoring, the PIC16LC711-04/P provides 4 channels of 8-bit ADC directly, eliminating the need for an external ADC chip. The 18-pin PDIP allows easy socket-mounting on control PCBs, simplifying field replacement. Its 0 C to +70 C commercial range covers most factory-floor enclosures, and the LC voltage range supports 24 V industrial bus rails after a simple regulator. The 4 MHz clock and 35-instruction opcode set enable responsive keypad scanning and LED multiplexing with predictable timing.
Recommended
Consumer White Goods Controller
Low-cost consumer white goods such as washing machine control boards, dishwasher timers, and small kitchen appliances use the PIC16LC711-04/P for its integrated ADC, low cost (~$1.76 at 500-piece pricing), and OTP memory that supports one-time production programming. The 4 MHz speed and 13 I/O pins easily handle relay driving, button matrix scanning, and rotary encoder input. The LC voltage range enables direct 3.3 V operation, allowing shared rails with display drivers. Mass-production economies of the PIC16C71X family keep unit costs low for high-volume appliance runs.
Recommended
Automotive Interior Accessory (Non-Safety)
For non-safety automotive interior accessories such as seat heaters, ambient lighting controllers, or window lift timers, the PIC16LC711-04/P is a proven low-cost solution. The automotive-grade version of this family uses the PIC16LC711-04I/P for -40 C to +85 C operation, which is the standard automotive interior temperature range. The integrated ADC reads NTC thermistor inputs for temperature-based seat heater control, and the SLEEP mode extends battery life when the vehicle is parked. Note: for safety-critical automotive applications, the AEC-Q100 qualified dsPIC or PIC18 variants are required instead.
Recommended
Legacy Embedded System Retrofit
The PIC16LC711-04/P is commonly used to retrofit legacy 8051 or PIC16C5X-based designs that require additional features such as an integrated ADC, more RAM (68 bytes), or wider voltage operation. The 18-pin PDIP footprint is pin-compatible with the broader PIC16C71X family, so redesigns can drop the LC variant into existing PCBs with no layout changes. The ICSP capability allows in-system firmware updates during retrofit, while OTP memory prevents accidental reprogramming in the field. This makes it a preferred migration target for legacy industrial equipment.

Key Differentiators
- Extended low-voltage VDD operation down to 2.5 V (vs PIC16C711-04/P)
- Industrial temperature grade variant available in same footprint (vs PIC16LC711-04I/P)
- Integrated 4-channel 8-bit ADC eliminating external chip (vs PIC16LC710-04/P)
Design Notes
Decouple VDD (pin 14) with a 0.1 uF ceramic capacitor placed within 5 mm of the IC pin, plus a bulk 10 uF electrolytic on the same rail. The PIC16LC711 has internal power-on reset but is sensitive to VDD droop during ADC conversion. If the design drives heavy loads from VDD, add a 100 ohm ferrite bead to isolate analog and digital supply noise. For sleep-current-sensitive battery designs, verify the actual Iq in the datasheet DC characteristics section because the value differs between LC and C variants.
Do not assume the MCLR pin (pin 4) can be left floating - it requires a 10 kohm pull-up to VDD for normal operation. When using ICSP programming, isolate MCLR from external reset circuitry with a series resistor or diode to prevent programming voltage conflicts. Watchdog timer is enabled by configuration fuse and must be either serviced in firmware or disabled to avoid unintended resets. The PORTA RA4 pin is open-drain and requires a pull-up for logic-high output.
The 18-pin PDIP (0.300 in / 7.62 mm) is through-hole with 2.54 mm (0.100 in) pin pitch. Reserve a standard DIP socket footprint for socket-mounting during prototype phases, especially for OTP parts that cannot be reprogrammed. Route the crystal or resonator traces between OSC1 (pin 16) and OSC2 (pin 15) symmetrically, with the load capacitors within 5 mm of the pins and a ground guard ring to minimize EMI pickup. Keep ADC analog traces (RA0-RA3) short and away from switching node traces.
Compliance Information
RoHS and lead-free status not explicitly stated in the verified web data; the LC-series PIC16C71X family is generally lead-free per Microchip policy but specific certificate PDF was not retrieved. AEC-Q100 not qualified - use dsPIC33CH AEC-Q100 variants for automotive safety applications.
