PIC16LC710-04E/SS Visão geral
An 8-bit microcontroller (MCU) is a small, self-contained programmable processor that combines a CPU, non-volatile program memory, volatile data memory, and peripheral interfaces on a single silicon die. The PIC16LC71X family sits in Microchip's mid-range architecture tier, sitting between base-line PIC10/12/16 devices and enhanced PIC17/18 parts, sharing the 14-bit instruction word of the mid-range core. PIC microcontrollers are widely used in embedded control because their Harvard architecture and RISC instruction set deliver deterministic, predictable execution timing with very low power consumption.
Key features of the PIC16LC710-04E/SS include a 4 MHz maximum operating frequency, an operating voltage range of 2.5 V to 5.5 V, an integrated 8-bit multi-channel A/D converter (typically 4 channels), brown-out reset (BOR) circuitry, a watchdog timer (WDT), Timer0 (8-bit) and Timer1/Timer2 peripherals, and individual direction control on all I/O pins. The 13 I/O pins support digital I/O plus analog input multiplexing for the on-chip ADC, making the device well-suited for sensor-interface front-ends.
The architecture uses a 14-bit-wide instruction word, separate program and data buses (Harvard), and a 2-level hardware stack typical of PIC mid-range devices. Static CMOS logic lets the clock be stopped for true zero-current standby, and brown-out detection protects against unreliable code execution during slow VDD ramp or brown-out events.
Typical applications include battery-powered sensor nodes, simple motor/relay control, white-goods user interfaces, automotive body electronics, and consumer appliances. Its integrated ADC, low supply voltage range, and small SSOP-20 footprint make it especially attractive when PCB area, BOM cost, and analog sensing all matter simultaneously.
When designing with this part, pay attention to the OTP program memory constraint: code must be verified before committing, since OTP cannot be erased. Designers typically develop firmware on windowed (JW) or UV-erasable (PE) siblings before moving to OTP for production.

Aplicações típicas
PIC16LC710-04E/SS é adequado para 7 aplicaçãos: Battery-Powered Sensor Node, White-Goods User Interface Controller, Automotive Body Electronics, Industrial Sensor Transmitter (4-20 mA), Small Motor Control (Brushed DC, PWM), Consumer Remote Control / IR Transmitter, Security & Access Control Keypad.
Battery-Powered Sensor Node
The PIC16LC710-04E/SS fits battery-powered sensor nodes because it operates from a 2.5 V to 5.5 V supply, supports slow clocking down to DC for nanoamp standby, and integrates a 4-channel 8-bit ADC for direct thermistor, photocell, or voltage-sensing without external signal conditioning. Its 36-byte RAM and 896-byte OTP program memory suffice for periodic sample-and-transmit firmware using UART or PWM-based one-wire protocols. Placed on a 2-layer PCB with a CR2032 or 2xAA cell, the MCU enables multi-year coin-cell runtime, and its low quiescent current (~1 uA typical in sleep with WDT disabled) makes it ideal for wireless HVAC sensors, occupancy detectors, and remote telemetry units.
Recomendado
White-Goods User Interface Controller
The PIC16LC710-04E/SS suits white-goods user interfaces such as washing machines, dishwashers, and microwave oven keypads because its 13 I/O pins drive 7-segment LED displays and button matrices directly while the integrated ADC reads analog knob positions or temperature sensors. Its 4 MHz core executes keypad-debounce, rotary-encoder tracking, and PWM backlight dimming in a single chip, and the brown-out reset plus watchdog timer protect against the line-voltage transients common in appliance environments. Placed on the user-interface PCB, the device replaces a discrete logic-board design and reduces BOM cost by 30-40%.
Recomendado
Automotive Body Electronics
The PIC16LC710-04E/SS is appropriate for automotive body-electronics sub-modules such as interior lighting controllers, seat-position memory, and mirror-adjustment modules, where its -40C to +125C Extended temperature range handles under-dash and door-module thermal stress. The integrated 8-bit ADC monitors battery voltage (12V via resistor divider), temperature, and current-sense inputs, while the PWM output drives LED strings or small DC motors. Placed behind a TVS-protected 12V input, the PIC16LC710-04E/SS delivers cost-optimized, deterministic control with the watchdog timer and brown-out reset ensuring reliable startup in cranking-voltage dropouts down to 6 V transient.
Recomendado
Industrial Sensor Transmitter (4-20 mA)
The PIC16LC710-04E/SS supports 4-20 mA loop-powered sensor transmitters because its 2.5 V minimum supply lets it operate from the 4 mA loop minimum with a low-dropout regulator front-end, and its 8-bit ADC digitizes bridge sensors, RTDs, or thermocouples referenced against the loop supply. Its 4 MHz core runs the linearization, range-mapping, and HART-style FSK modulation firmware in the 896-byte OTP budget, while the PWM output drives the loop-current controlling NPN transistor. Placed in a head-mount transmitter housing, the MCU meets intrinsic-safety power budgets below 1 mA quiescent, and its 36-byte RAM is sufficient for moving-average filtering.
Recomendado
Small Motor Control (Brushed DC, PWM)
The PIC16LC710-04E/SS drives small brushed DC motors in toys, small appliances, and HVAC damper actuators because its Capture/Compare/PWM module generates the switching signal directly and its ADC samples the motor current shunt for closed-loop torque or speed control. Its 13 I/O pins allocate 2 for PWM outputs (one direction + brake), 2 for quadrature encoder input, and several for end-stop and button inputs, fitting typical 2-wire bidirectional motor-control topologies. Placed on a motor-control PCB with dual N-FET half-bridges, the PIC16LC710-04E/SS delivers variable-speed torque control with hardware brown-out protection preventing FET shoot-through during low-battery conditions.
Recomendado
Consumer Remote Control / IR Transmitter
The PIC16LC710-04E/SS is well-suited to consumer IR remote controls and wireless key fobs because its 2.5 V minimum supply runs from a single 3 V coin cell, the PWM module generates 38 kHz carrier for IR LED modulation, and the 36-byte RAM holds 8-16 button states plus timing. Its low-power CMOS design yields years of battery life when the MCU spends most of its time in sleep mode with WDT waking it on button-press interrupts. Placed in a remote-control PCB, the PIC16LC710-04E/SS drives the IR LED directly via a single transistor and supports multi-protocol encoding (RC5, NEC, SIRC) within its 896-byte OTP budget.
Recomendado
Security & Access Control Keypad
The PIC16LC710-04E/SS powers security keypad controllers for door access and alarm panels because its 13 I/O pins scan 4x4 matrix keypads directly while the ADC detects tamper-switch resistance changes and supervises the backup-battery voltage. Its watchdog timer and brown-out reset ensure the lock or alarm state is held in non-volatile EEPROM during power outages, and the 4 MHz core runs debounce, code-comparison, and relay-driver firmware within the 896-byte OTP budget. Placed in an access-control panel, the MCU replaces a discrete logic-board design with a single IC and provides magnetic-stripe or Wiegand-card reader interfaces via UART/SPI.

Notas de projeto
PIC16LC710-04E/SS uses OTP (One-Time Programmable) memory - firmware errors cannot be erased and re-flashed in production. Estimated: always develop and validate code on a JW (windowed CERDIP) or PE (UV-erasable) sibling before committing to OTP parts; failed OTP units must be physically discarded, raising production cost. Budget for at least one engineering prototype cycle plus a final OTP qualification run.
Decouple VDD (pin 20) and VSS (pin 19) with a 100 nF ceramic capacitor placed within 5 mm of the package, plus a 10 uF bulk tantalum or aluminum-polymer capacitor at the supply entry point. The PIC16LC710-04E/SS internal analog and digital sections share VDD, so high-current Port B transitions can inject supply noise into the ADC; a small ferrite bead (600 ohm at 100 MHz) on VDD reduces this effect during ADC sampling.
Place the crystal (or ceramic resonator) within 5 mm of pins 15 (OSC1) and 16 (OSC2), with short symmetric traces to keep the oscillator startup margin and frequency stability within datasheet limits. The MCLR/VPP pin (pin 4) needs a 10 kohm pull-up to VDD and a 100 nF decoupling cap to VSS for proper reset behavior during power-up; do NOT leave MCLR floating or the device may enter programming mode unexpectedly.
The PIC16LC710-04E/SS ADC conversion accuracy depends on source impedance; per Microchip's PIC16C71X datasheet, the analog input source impedance should be below 10 kohm to avoid gain and offset errors caused by the ADC's sample-and-hold charging current. Add an op-amp buffer or a low-pass RC network when sensing high-impedance sensors like pH probes or photodiodes.
