PIC16LC710T-04/SS - 4MHz 8-bit OTP MCU, 13 I/O, 20-SSOP | Microchip
MPN: PIC16LC710T-04/SS ✓ نشطPIC16LC710T-04/SS نظرة عامة
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, working RAM, and digital and analog peripherals on one die. The PIC16LC710T-04/SS belongs to the broader category of embedded controllers -> microcontrollers (MCU) -> 8-bit MCU -> PIC mid-range core, where the LC suffix indicates the low-voltage CMOS process and the OTP memory class is field-programmable but not re-programmable, making the part well suited to low-to-mid volume production.
Key features include 4 MHz maximum operating frequency, 4 channels of 8-bit A/D with multiplexer, one 8-bit Timer0 with prescaler, one 16-bit Timer1 with prescaler that can be clocked during Sleep, an 8-bit Timer2, a Pulse-Width Modulation (PWM) module, a Watchdog Timer with its own on-chip RC oscillator, Brown-out Reset (BOR), and an internal/external interrupt structure. The 20-pin SSOP (5.30 mm body) package is a shrink-SOIC variant optimized for surface-mount density.
Architecturally, the PIC16LC710T-04/SS uses the Microchip mid-range 14-bit instruction set with a 200 ns instruction cycle at 4 MHz, an 8-level hardware stack, and direct, indirect, and relative addressing. The Harvard-style split program/data bus allows simultaneous fetch and access, which improves deterministic throughput for real-time control loops.
Typical applications include appliance control, sensor signal conditioning with on-chip A/D, low-cost motor control via PWM, battery-powered instrumentation, and consumer white goods. It is also widely used in industrial 24 V/5 V bridging nodes and in educational/prototyping platforms where OTP cost advantages outweigh in-circuit reprogrammability.
When designing with this part, plan the A/D acquisition time versus the oscillator frequency and place a local 0.1 µF decoupling capacitor adjacent to VDD. Note that this -04 speed grade is rated to 4 MHz; designers needing higher throughput should evaluate the -20 (20 MHz) variant or migrate to a flash-based PIC16F equivalent.

التطبيقات النموذجية
PIC16LC710T-04/SS مناسب لـ 6 التطبيقs: Appliance Control Boards, Battery-Powered Sensor Conditioning, Low-Cost PWM Motor Control, Consumer White Goods Interface Panels, Industrial 24 V to 5 V Sensor Nodes, Educational / Prototyping Platforms.
Appliance Control Boards
The PIC16LC710T-04/SS fits appliance control boards where 13 digital I/O pins, one PWM channel, and a 4-channel 8-bit ADC are sufficient to read user inputs, drive triac-friendly outputs, and sense temperature or humidity. The 2.5 V to 5.5 V supply range matches the regulated rails inside washing machines, microwave ovens, and induction cooktops, and the BOR/Watchdog combination ensures safe recovery from brown-out events on noisy AC-derived supplies. Compared with a switching front end, the PIC16LC710T-04/SS adds no switching noise to the analog front end, simplifying the EMC filter. A typical implementation uses the PWM output to drive a low-side MOSFET for fan or pump speed control, while the ADC samples thermistor dividers for closed-loop regulation.

Battery-Powered Sensor Conditioning
The PIC16LC710T-04/SS is well suited to battery-powered sensor-conditioning nodes that require a small mixed-signal front end and very low standby current. The 8-bit ADC handles up to four sensors (temperature, humidity, light, or gas) and the LC process supports full-speed operation down to 2.5 V, extending usable battery life from a single 3 V coin cell or two AA cells. The 4 MHz maximum CPU clock keeps active power consumption low, and the Brown-out Reset prevents corrupted writes when the battery droops near end-of-life. Designers typically run Timer1 from a 32.768 kHz crystal during Sleep to wake the device periodically, then service the ADC and PWM outputs before returning to Sleep.

Low-Cost PWM Motor Control
The PIC16LC710T-04/SS supports low-cost brushed DC motor control via its on-chip PWM module plus the 8-bit ADC for closed-loop current or speed sensing. Operating up to 4 MHz, the part can drive MOSFET gate drivers for sub-100 W motors used in small fans, pumps, and toy vehicles. The 13 I/O pins can be allocated to direction control, fault inputs, and Hall-effect sensor feedback, while the PWM duty cycle is updated from the ADC result to maintain regulation. Compared with a dedicated motor-control IC, this PIC mid-range MCU offers programmable flexibility for soft-start, current limit, and stall-recovery algorithms at a fraction of the cost.

Consumer White Goods Interface Panels
The PIC16LC710T-04/SS is a strong fit for consumer white-goods interface panels where it scans button matrices, drives 7-segment or LED indicators via its GPIO, and reads analog inputs from potentiometers or thermistors. The 20-SSOP package fits behind a small display PCB, and the LC supply range lets the MCU share a 3.3 V rail with the panel backlight driver. Brown-out Reset protects user settings stored in RAM during power dips caused by mains transients. The 4-channel ADC is sufficient to read water level, temperature, and door-latch analog sensors without external signal conditioning.

Industrial 24 V to 5 V Sensor Nodes
The PIC16LC710T-04/SS can be paired with a small buck regulator to form a 24 V industrial sensor node that monitors a process variable and transmits the reading via GPIO bit-banging or a serial protocol. Its 36-byte RAM is sufficient to buffer a few sensor samples and a serial frame, while the 8-bit ADC handles up to 4 inputs from bridge sensors, RTDs, or 4-20 mA loops via external conversion. The industrial-temperature variant is required for deployments near motors or outdoor enclosures, and the Watchdog Timer with dedicated RC ensures the node recovers from software faults without external intervention.

Educational / Prototyping Platforms
The PIC16LC710T-04/SS is widely adopted in educational and prototyping platforms because its 14-bit instruction set, 35 single-word instructions, and 8-level hardware stack are easy to teach and debug in classroom settings. The integrated A/D and PWM allow students to complete real mixed-signal labs without external ICs, and the 20-SSOP package is friendly to breakout-board adapters for breadboarding. Compared with more complex 32-bit ARM Cortex devices, this 8-bit MCU keeps the focus on fundamentals: timing, interrupts, and register-level peripheral control. Its low cost and Microchip's MPLAB X IDE support make it a popular starter device.

ملاحظات التصميم
Place a local 0.1 µF decoupling capacitor as close as possible to the VDD pin (pin 20) and a bulk 10 µF capacitor at the regulator output. The PIC16LC710T-04/SS draws a few mA active at 4 MHz; the LC process allows full-speed operation down to 2.5 V. For Sleep-mode operation, gate all unused peripherals via the TRIS registers and disable the ADC to minimize sub-µA standby current.
Estimated: at 4 MHz active and 5 V VDD, the PIC16LC710T-04/SS typically draws ~2 mA active, which is 10 mW dissipation - well within the 20-SSOP thermal envelope (theta_JA ~ 90 C/W on a 1 oz 4-layer board). For closed enclosures without airflow, ensure the board temperature stays below 70 C ambient for the commercial -04 grade, or migrate to the industrial -I/SS variant for harsher environments.
Route the MCLR line with a short trace to its pull-up resistor and keep the OSC1/OSC2 traces short and surrounded by ground to avoid coupling noise into the internal clock. The SSOP-20 lead pitch is 0.65 mm; use a fine-pitch soldering tip and no-clean flux if hand-rework is required. Expose a generous copper pour under the package to share thermal load and reduce ground-bounce on I/O switching.
Do not confuse the -04 speed grade (4 MHz) with the -20 grade (20 MHz); programming the device for >4 MHz oscillator operation will cause out-of-spec timing and possible EEPROM/OTP write corruption. Also, ensure the A/D acquisition time is programmed for at least 19.72 µs (Tad = 1.6 µs minimum at 4 MHz) when the ADC is enabled, and always set the TRIS bits for ADC channels as inputs before the GO/DONE bit is asserted.
