PIC16C711T-04/SO - 8-Bit 4MHz OTP MCU 1.75KB | Microchip
MPN: PIC16C711T-04/SO ✗ Cuối đờiPIC16C711T-04/SO Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (program + data), and programmable I/O peripherals into one package. The PIC16C711 sits within the broader taxonomy: microcontroller -> embedded processor -> integrated circuit -> semiconductor. OTP MCUs are programmed once via dedicated programmers and retain code without a battery, distinguishing them from flash-based parts. Mid-range PIC MCUs target cost-sensitive, deterministic control applications where simplicity, low cost, and predictable interrupt latency outweigh large memory footprints.
Key features of the PIC16C711 include four channels of 8-bit A/D conversion with on-chip sample-and-hold, an internal 4MHz RC oscillator option, power-on reset, watchdog timer with on-chip RC oscillator, code protection, and a wide operating voltage range that supports both 5V regulated and battery-powered designs. The 'T-04' suffix denotes tape-and-reel packaging and the 4MHz speed grade, while the 'I' or 'E' variants extend the industrial temperature range to -40C to +125C. The SOIC-18 footprint is one of the most common surface-mount 8-bit MCU packages, allowing hand-prototyping and reflow assembly.
Architecturally, the PIC16C711 uses a 14-bit instruction word, an 8-bit data path, and a two-stage pipeline, giving an effective throughput of 5 MIPS at 20MHz. The Harvard-style separate program and data buses allow the next instruction to be fetched while the current one executes, a hallmark of PIC performance efficiency. The integrated ADC draws from a dedicated reference and the device's VDD rail, simplifying sensor-interface designs that previously required an external converter.
Typical applications for the PIC16C711T-04/SO include consumer appliance control, automotive interior modules, sensor signal conditioning, simple motor control loops, security alarm keypads, HVAC damper drivers, low-cost battery chargers, and embedded educational platforms. The 5V operating point and 13 I/O pins make it well suited to interfacing 5V logic peripherals and analog sensor front-ends without level translation. Microchip explicitly recommends the flash-based PIC16F716 as a modern, drop-in-compatible replacement for new designs.
When designing with this part, ensure programmer compatibility (PICSTART Plus, MPLAB PM3, or third-party OTP programmers) and confirm that your tool chain supports OTP mid-range PIC devices. Because OTP cannot be reprogrammed, allocate engineering time to in-system emulation via MPLAB ICE or a PIC16F716 flash equivalent during firmware bring-up before committing the OTP one-time programming budget.

Ứng dụng tiêu biểu
PIC16C711T-04/SO phù hợp cho 6 Áp dụngs: Consumer Appliance Control, Automotive Interior Modules, Sensor Signal Conditioning, Security and Alarm Keypads, Battery Charger Controllers, Educational and Hobby Platforms.
Consumer Appliance Control
The PIC16C711T-04/SO fits consumer appliance control thanks to its 5V operation, 13 digital I/O pins, and integrated 4-channel 8-bit ADC. Its 4 MHz oscillator and 35-instruction RISC core deliver deterministic control loops ideal for washing-machine controllers, microwave oven user interfaces, and small kitchen appliances. Unlike flash MCUs, the OTP memory reduces per-unit cost once firmware is finalized, while the 4-channel ADC reads thermistor, weight, and humidity sensors directly, eliminating an external converter. The wide 3.0-5.5V supply range also tolerates rectified mains-derived rails typical in appliance designs.

Automotive Interior Modules
The PIC16C711T-04/SO suits automotive interior modules such as HVAC flap drivers, seat position controllers, and lighting dimmers. The 4 MHz clock, 200ns instruction cycle, and 13 I/O lines give deterministic control over stepper or DC motors, while the 4-channel ADC reads position feedback and temperature sensors. The industrial-grade 711T-04I/SO variant extends the temperature range to -40 C to +85 C, meeting the cabin environment envelope. Although automotive safety-critical systems require Q-100 certified parts, the 711 platform remains useful for non-safety interior convenience features.

Sensor Signal Conditioning
The PIC16C711T-04/SO operates as a low-cost sensor signal conditioner, using its 4-channel 8-bit ADC to digitize analog front-end signals and its 13 I/O pins to drive calibration relays or status LEDs. The 5V supply and 0-5V ADC input range pair naturally with sensors that output 0-5V ratiometric signals, such as potentiometric position sensors, photo-diodes with transimpedance amplifiers, and low-cost strain gauges. Firmware running on the 35-instruction RISC core applies linearization, averaging, and threshold comparisons before driving a 4-20mA loop or PWM output.

Security and Alarm Keypads
The PIC16C711T-04/SO is a strong fit for security alarm keypads and simple access-control panels. Its 13 I/O pins matrix-scan a 4x4 keypad (using 8 lines) and drive status LEDs, piezo buzzers, and a relay output for the door strike. The 1.75KB OTP memory stores the keypad map and PIN-validation logic, while the 4-channel ADC supports battery monitoring on the backup cell. The OTP architecture reduces reverse-engineering risk, an advantage for anti-tamper applications. Low standby current and the 3-5.5V operation preserve battery life.

Battery Charger Controllers
The PIC16C711T-04/SO can manage low-power NiMH or lead-acid battery chargers by combining its 8-bit ADC for voltage and current sensing, its 13 I/O pins for relay/PFET control, and the deterministic 4 MHz core for closed-loop PWM regulation. Charge states (trickle, bulk, absorption, float) fit comfortably in the 1.75KB OTP program space along with temperature-compensation tables. The wide supply range tolerates direct connection to a 6V or 12V nominal source after external regulation. The OTP one-time-programmable nature prevents field firmware tampering that could overcharge cells.
Được đề xuất
Educational and Hobby Platforms
The PIC16C711T-04/SO is widely used in undergraduate embedded systems and hobbyist projects because the PIC16 mid-range architecture is simple (35 instructions, 14-bit words), well-documented, and supported by free MPLAB X IDE toolchains. The 18-pin SOIC package is breadboard-friendly with adapter boards, while the on-chip ADC lets students explore analog interfacing without external chips. PICkit programmers and PICSTART Plus support OTP programming in teaching labs. The 4 MHz instruction cycle provides a 200ns time base that is straightforward to reason about in assembly tutorials.

Ghi chú thiết kế
Because the PIC16C711 is OTP (one-time-programmable), firmware must be fully verified in silicon via an MPLAB ICE emulator or a flash-based stand-in (PIC16F716) before committing to a programming slot. A single bad bit in production OTP programming renders the device unusable; in 2026 supply conditions with NRN-D status, each wasted part represents a $3-4 yield loss. Recommended: build a small PIC16F716 prototype, then port the final HEX to the OTP 711 only after firmware freeze.
The PIC16C711T-04/SO operates from 3.0 V to 5.5 V, with a typical 5V design drawing approximately 2-5 mA active and under 1 uA in sleep. Place a 100 nF decoupling capacitor within 5 mm of the VDD pin and a bulk 10 uF electrolytic at the regulator output to suppress digital switching noise. The MCLR/VPP pin requires a 10 kohm pull-up to VDD for normal operation; if not used in-circuit, ensure the programmer can drive VPP to 13V during programming.
The 18-pin SOIC footprint is one of the most common surface-mount packages and reflows cleanly on standard lead-free profiles (peak 245 C, 60 s above 217 C). Recommended pad dimensions: 1.27 mm pitch, 0.55 mm pad width, 2.0 mm pad length. Use a ground plane on the bottom layer directly under the MCU to provide a low-impedance return path for the ADC reference and to improve noise immunity on analog inputs AN0-AN3.
Route the analog inputs AN0-AN3 and the VREF pin away from digital switching traces (OSC, RB port edges) to minimize ADC noise coupling. Add a small RC filter (1 kohm + 100 pF) on each analog input to suppress MHz-range noise. Keep the crystal or ceramic resonator within 5 mm of OSC1/OSC2 to avoid stray capacitance, and route the MCLR trace as short as possible to maintain reset integrity in noisy environments.
