PIC16C711-04/P - 8-bit 4MHz 1.75KB OTP MCU 18-PDIP | Microchip
MPN: PIC16C711-04/P ✗ Akhir HidupPIC16C711-04/P Ringkasan
An 8-bit microcontroller (MCU) is a small computer-on-a-chip that integrates a CPU, non-volatile program memory, working RAM, digital I/O, and (in this case) analog peripherals into a single IC. The PIC16C711 belongs to the broader hierarchy: microcontroller -> embedded controller -> microprocessor system -> integrated circuit -> semiconductor. It targets applications where deterministic real-time control and modest on-chip analog performance outweigh the need for larger flash memory or higher clock speeds.
Key specifications include a 200 ns instruction cycle, 13 digital I/O pins, an 8-bit timer/counter (TMR0) with an 8-bit prescaler, a watchdog timer with its own on-chip RC oscillator for reliable operation, and a wide 2.5 V to 6.0 V operating voltage range. The integrated A/D converter provides four input channels with 8-bit resolution and a typical conversion time compatible with the 4 MHz oscillator. Brown-out reset and power-on reset simplify power supply design.
Architecturally, the PIC16C711 uses a Harvard RISC core with separate program and data buses and a 14-bit wide instruction word. The OTP program memory enables code customization at production time while keeping per-unit cost low, and the fully-static CMOS design ensures operation across DC to the maximum rated frequency. Compared with later PIC16F parts, the OTP cell is replaced by flash, but the instruction set, peripheral set, and pinout are largely preserved, simplifying migration.
Typical applications include entry-level A/D applications in automotive sensor signal conditioning, industrial process control front-ends, appliance control boards, and consumer products such as battery chargers and small appliances. The 18-pin PDIP package is also well suited to prototyping, hobbyist projects, and through-hole industrial designs where socketed parts simplify field service.
When designing with the PIC16C711-04/P, note that the -04 speed suffix designates the 4 MHz maximum oscillator; for higher-frequency operation, choose the -20 variant. A stable oscillator and proper decoupling near VDD are critical to A/D accuracy.

Aplikasi Umum
PIC16C711-04/P cocok untuk 6 aplikasis: Entry-Level A/D Sensor Signal Conditioning, Industrial Process Control Front-End, Appliance Control Boards, Automotive Sensor Modules (Legacy), Battery Chargers and Power Management, Educational and Hobbyist Prototyping.
Entry-Level A/D Sensor Signal Conditioning
The PIC16C711-04/P integrates a 4-channel 8-bit A/D converter alongside an 8-bit RISC core, making it a compact single-chip solution for digitizing analog sensor outputs in entry-level designs. With 4 MHz CPU clock and 200 ns instruction cycle, the MCU can sample and post-process four channels at modest update rates suitable for thermistor, photocell, or potentiometer front-ends. Its 2.5 V to 6.0 V operating range allows direct connection to 5 V analog rails without level shifting. Compared with using a discrete ADC plus separate MCU, the PIC16C711-04/P reduces BOM count and PCB area while keeping firmware simple through the PIC16CXX mid-range instruction set.

Industrial Process Control Front-End
The PIC16C711-04/P suits industrial process control front-ends that require reliable 8-bit computation, brown-out reset, and an integrated watchdog timer with dedicated on-chip RC oscillator. The watchdog provides fail-safe recovery independent of the system clock, an essential feature for factory automation nodes. The 18-pin PDIP package is socketable, simplifying field service for installed PLC-style I/O modules. The 8-bit ADC captures 4-20 mA loop-derived voltages through scaling resistors, while the 13 digital I/O drive indicator LEDs and relay coils via transistors.

Appliance Control Boards
Consumer and white-goods appliance control boards benefit from the PIC16C711-04/P's combination of OTP memory (low per-unit cost in high volume), integrated ADC, and 18-pin PDIP form factor that fits legacy through-hole assembly lines. Typical uses include washing-machine water-level sensing, microwave oven keypad scanning, and small kitchen-appliance thermostat control. The PIC mid-range 35-instruction set is straightforward for appliance firmware teams, and brown-out reset handles noisy rectified mains environments. OTP eliminates in-field firmware tampering risk for safety-critical consumer devices.

Automotive Sensor Modules (Legacy)
Although not AEC-Q100 qualified, the PIC16C711-04/P has historically been used in non-safety automotive sub-modules such as seat-position sensors, HVAC flap position feedback, and ambient light sensors. The integrated 8-bit ADC reads four sensor channels, and the watchdog timer ensures recovery from electrical transients common in 12 V automotive environments. The -04I/P industrial variant extends operation to -40 C to +85 C. Designers targeting new automotive designs should select AEC-Q100 qualified parts such as PIC16F1939 or dsPIC33 families, per Microchip automotive product selection guidance.

Battery Chargers and Power Management
The PIC16C711-04/P's 2.5 V to 6.0 V operating range makes it well suited to single-cell Li-ion and multi-cell NiMH battery chargers that monitor voltage, current, and temperature via the 4-channel ADC. The 13 digital I/O control charging FETs, indicator LEDs, and user input buttons, while the 4 MHz CPU is fast enough for CC/CV charge profile updates. Brown-out reset and the watchdog timer protect batteries from firmware lockup. Compared with dedicated charger ICs, the PIC16C711-04/P provides flexible, user-upgradable charge algorithms via OTP programming.

Educational and Hobbyist Prototyping
The PIC16C711-04/P's 18-pin PDIP through-hole package is breadboard-friendly and widely used in university embedded systems courses, hobbyist robotics, and Maker projects. Students can program the OTP device with low-cost PIC programmers such as PICkit 2/3 in development, then move to PIC16F711 for final flash-based deployment. The 4 MHz internal clock option removes external crystal requirements for the simplest projects, while the 4-channel ADC teaches analog signal acquisition fundamentals.

- Faster execution than the -04 speed grade (vsPIC16C711-10/P)

- Reprogrammable flash instead of one-time-programmable memory (vsPIC16F711-I/P)
Catatan Desain
Place a 0.1 uF ceramic decoupling capacitor as close as possible to the VDD pin (pin 14) and a bulk capacitor (e.g., 10 uF tantalum or aluminum) at the supply rail. The PIC16C711-04/P draws modest current (typically < 2 mA active, < 1 uA sleep) but the integrated ADC is sensitive to supply noise - a clean analog supply filtered through a ferrite bead is recommended when sampling low-level signals below 100 mV full scale.
For through-hole 18-pin PDIP designs, route the crystal/oscillator traces (OSC1/OSC2) as short as possible and keep them away from high-current switching traces to avoid injecting clock noise into the ADC. When using ICSP programming via RB6/RB7, ensure those pins are not pulled low by external circuitry during reset - this is a common boot failure mode on PIC16 mid-range devices, per Microchip ICSP application notes.
Do not assume the PIC16C711-04/P is field-reprogrammable: OTP memory can be programmed once and cannot be erased or rewritten. For prototypes and field-upgradable designs, use the PIC16F711 (flash) variant instead - it shares the same 18-pin PDIP pinout and most peripheral registers but allows in-system reprogramming via ICSP. Brown-out reset and watchdog configuration bits must be set correctly during OTP programming; mistakes cannot be undone.
