PIC16C711T-04I/SS 개요
A microcontroller (MCU) is a single-chip computer containing a CPU, program and data memory, I/O peripherals, and a clock generator. OTP microcontrollers are programmed once with a firmware image and cannot be re-erased, which lowers unit cost compared with flash-based parts and makes them well-suited to high-volume, closed-firmware appliances. The PIC16C71X family adds an integrated successive-approximation ADC, eliminating the need for an external converter in sensor-interface designs.
Key features include the 4 MHz maximum clock rate, 1.75 KB OTP program memory (1K x 14 words), 68 bytes of data RAM, four 8-bit I/O ports (PORTA 5 bits, PORTB 8 bits), and a 4-channel 8-bit ADC with on-chip sample-and-hold. The device supports in-circuit serial programming, low-power SLEEP mode, and a programmable watchdog timer. The RISC-style PIC16 architecture uses only 35 single-word instructions, simplifying code generation in C or assembly.
Built on a low-power CMOS process, the PIC16C711 implements the PIC16 mid-range core with a 14-bit instruction word and an 8-bit data path. The integrated 8-bit ADC samples analog inputs on RA0-RA3, allowing direct connection of resistive sensors, thermistors, or potentiometers without external signal conditioning. The internal RC oscillator option and power-on reset reduce external component count.
Typical applications include white-goods and appliance control (washing machines, dishwashers, microwave ovens), battery chargers, automotive body electronics (non-safety subsystems), sensor signal conditioning nodes, and small consumer devices (remote controls, thermostats, toy subsystems). The 4 MHz industrial-grade part is well-matched to mains-frequency signal processing and slow control loops.
When designing with this part, ensure the OTP window is left on or off according to the in-circuit-programming method selected, place a 0.1 µF decoupling capacitor within 5 mm of VDD, and reserve the RA4 pin as an open-drain output if used for T0CKI. The Microchip PIC16F716 is the recommended newer pin-compatible alternative for new designs requiring flash memory, while PIC16C711T-04I/SS remains preferred for high-volume cost-down production.

일반적인 애플리케이션
PIC16C711T-04I/SS 적합 용도: 6 애플리케이션s: White Goods Appliance Control, Battery Charger Control, Sensor Signal Conditioning Nodes, Remote Control and Toy Subsystems, HVAC Thermostat and Fan Control, Automotive Body Electronics (Non-Safety).
White Goods Appliance Control
The PIC16C711T-04I/SS is well suited for white-goods appliance control because its 1.75 KB OTP program memory holds a complete washing-machine or dishwasher cycle state machine, while the integrated 4-channel 8-bit ADC samples water temperature, turbidity, and motor current directly. Operating from 4.0-6.0 V, the part interfaces to triac-driver optos and 24 V relay coils through PORTB. The industrial -40 to +85°C range covers under-cabinet thermal load, and the 5 MIPS throughput at 4 MHz supports PID temperature control with millisecond update rates. Pin-to-pin compatibility with PIC16F716 allows easy migration to flash for firmware updates during production validation. Recommend PIC16C711T-04I/SS as the production cost-down part once firmware is locked.
추천
Battery Charger Control
The PIC16C711T-04I/SS delivers deterministic closed-loop control for NiCd, NiMH, and SLA battery chargers, where its 8-bit ADC samples charge current (typically 0.1-2 A) via a sense resistor, and PORTA outputs drive the PWM switch. The 4 MHz clock supports 8-bit PWM at sub-1 kHz refresh, sufficient for CC/CV charge profiles. At VDD=5 V and active current ~2 mA, the part contributes negligible quiescent drain during the long float-charge phase, and SLEEP mode (< 1 µA) handles the standby state when the battery is full. The industrial temperature grade supports under-hood and garage-environment operation. The OTP memory is ideal because the charge algorithm is fixed at firmware time and need never change.
추천
Sensor Signal Conditioning Nodes
The PIC16C711T-04I/SS is a natural fit for distributed sensor nodes because its 4-channel 8-bit ADC accepts direct inputs from thermistors, photocells, and potentiometers without external signal conditioning, and its 13 I/O pins drive indicator LEDs, relays, and a UART or SPI debug port. At 4 MHz the part executes linearization, hysteresis, and averaging routines in real time at sub-ms loop rates. The 4-6 V supply range covers 5 V regulated industrial buses, and the SSOP-20 footprint fits compact sensor housings. The 1.75 KB OTP program memory holds both calibration constants and the application firmware, eliminating the need for an external EEPROM. Industrial temperature operation handles factory-floor and outdoor cabinet environments.
추천
Remote Control and Toy Subsystems
The PIC16C711T-04I/SS delivers cost-effective 8-bit intelligence for consumer remote controls, educational toys, and low-end hobbyist subsystems. The 35-instruction PIC16 RISC core is easy to program in assembly, and 1.75 KB of OTP holds a complete IR-protocol state machine or motor-sequence controller. SLEEP mode (< 1 µA) extends battery life when the toy is idle; active ~2 mA at 4 MHz supports weeks of playtime on two AA cells. The 13 I/O pins drive IR LEDs, pushbuttons, piezo buzzers, and DC motor bridges directly. The SSOP-20 surface-mount package is suitable for automated high-volume assembly; the tape-and-reel 'T' format suits pick-and-place feeders. OTP memory locks the firmware at production time, preventing field tampering.
추천
HVAC Thermostat and Fan Control
The PIC16C711T-04I/SS implements the closed-loop control for a wall-mount thermostat, where its 8-bit ADC reads the room thermistor and a 7-segment LED driver interface, while PORTB outputs switch the fan relay and the heat-cool valve. The 4 MHz clock supports a 1-second PID update rate with hysteresis, suitable for residential comfort control. Industrial temperature operation ensures the controller survives attic and equipment-room conditions. The 1.75 KB OTP memory locks the calibration curve and the temperature setpoint logic, eliminating the need for a separate configuration EEPROM. The 5 MIPS throughput handles the UI scanning (buttons, LEDs) plus control arithmetic in a single chip.
추천
Automotive Body Electronics (Non-Safety)
The PIC16C711T-04I/SS supports cost-sensitive automotive body-electronics applications such as seat-position memory, mirror-fold controllers, and ambient lighting drivers, where the 1.75 KB OTP locks the calibration and the 13 I/O pins drive relay coils and PWM LED strings. The industrial -40 to +85°C temperature range covers cabin and trunk environments. Operating from 5 V regulated, the part interfaces to 12 V loads through MOSFET drivers. Note that this part is NOT AEC-Q100 qualified; for safety-critical or under-hood applications, choose PIC16F716-I/SS or a Q-qualified PIC16 alternative. OTP memory is preferred in automotive to prevent field firmware tampering.

설계 노트
Place a 0.1 µF X7R ceramic decoupling capacitor within 5 mm of the VDD pin (pin 20 or pin 14), with a 10 µF bulk tantalum or aluminum capacitor on the same VDD trace. The PIC16C711T-04I/SS draws approximately 2 mA active at 4 MHz / 5 V, with peaks during ADC conversions. Add a series ferrite bead (600 Ω at 100 MHz) if VDD is shared with relay or motor drivers to prevent digital switching noise from coupling into the analog reference.
The PIC16C711T-04I/SS SSOP-20 package has theta_JA of approximately 95 °C/W in still air. At maximum active current (2 mA at 6 V) power dissipation is only 12 mW, so thermal derating is not a concern for normal operation. However, when programming in-circuit via high-voltage VPP on MCLR, the elevated voltage can raise junction temperature by 5-10 °C - this is well within the industrial -40 to +85°C rating.
Keep the analog inputs (RA0-RA3) traces short and routed away from the oscillator pins (OSC1, OSC2) and PORTB digital outputs. The integrated 8-bit ADC has a 10 µs acquisition window; 20 ns edge transitions on adjacent traces can introduce 1-2 LSB crosstalk. Place the analog ground island under pins 1-3 and 17-18, and stitch it to the main ground plane with a single trace near the VSS pin. This reduces ADC noise by 30-50%.
The RA4 pin (pin 18) is open-drain and requires an external pull-up resistor (typically 4.7 kΩ to VDD) when used as a digital output - failure to add this pull-up is a common board bring-up issue. Additionally, the MCLR pin (pin 4) is configured as a reset input by default and requires a 10 kΩ pull-up to VDD for normal operation; leaving MCLR floating causes intermittent resets. When using the internal RC oscillator, the OSCO pin must be left unconnected.
The PIC16C711T-04I/SS ADC reference defaults to VDD, which means power-rail noise directly couples into conversion results. For higher precision, drive the RA3/AN3/VREF pin with a dedicated 5.0 V reference such as MCP1541 or LM4040 - this improves ADC noise performance by 4-6 LSB at 8-bit resolution. Sample-and-hold acquisition time is 19.72 µs minimum according to the datasheet; do not exceed the 8 ADC-clock conversion period without consulting the electrical characteristics table.
