PIC16C711T-04/SS - 4MHz 8-bit OTP MCU 1.75KB | Microchip
MPN: PIC16C711T-04/SS ✗ Akhir HidupPIC16C711T-04/SS Ringkasan
A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory, working RAM, and a configurable set of peripherals such as ADC, timers, and GPIO. The PIC16C711 belongs to the broader mid-range PIC taxonomy (PIC16C -> 8-bit PIC -> PIC architecture -> microcontroller -> semiconductor IC) and was designed as an upward-compatible evolution of the earlier PIC16C5X baseline family. The integrated 8-bit ADC made it especially attractive for sensor-interface designs where a separate ADC IC would otherwise be required.
Key features include a 4 MHz maximum clock frequency with 200 ns instruction cycle, 1.75 KB (1024 x 14) of OTP program memory, 68 bytes of data RAM, 13 bidirectional I/O pins, four multiplexed 8-bit ADC channels, and a wide 4 V to 6 V supply range. Peripherals include a single 8-bit timer/counter with prescaler, a watchdog timer with dedicated on-chip RC oscillator, and a power-on reset (POR) circuit. The 20-pin SSOP footprint supports compact designs in industrial temperature grade.
Architecturally, the PIC16C711 uses a RISC-style Harvard architecture with separate program (14-bit) and data (8-bit) buses, allowing simultaneous fetch and access. The 35 single-word instruction set is fully upward-compatible with the PIC16C5X baseline family, easing migration of legacy code. The integrated 8-bit ADC employs a successive-approximation register (SAR) topology with four multiplexed input channels selected through the ADCON0 register.
Typical applications include industrial sensor signal acquisition, white-goods and appliance control, low-cost battery-powered instrumentation, automotive body electronics (in non-safety systems), and embedded control subsystems requiring on-chip ADC. The OTP memory suits a target final product profile rather than field-upgradeable firmware, making the part best suited for high-volume production where unit cost matters more than in-circuit reprogrammability.
When designing with this device, note that Microchip explicitly recommends the flash-based PIC16F716 as a newer alternative for new designs. The OTP memory cannot be erased or rewritten, so firmware must be fully validated before programming. Decoupling capacitors (100 nF ceramic plus a bulk electrolytic) must be placed close to the VDD/VSS pins to ensure clean ADC readings.

Aplikasi Umum
PIC16C711T-04/SS cocok untuk 6 aplikasis: Industrial Sensor Signal Acquisition, White Goods and Appliance Control, Battery-Powered Instrumentation, Automotive Body and Comfort Electronics, Embedded Control Subsystem with On-Chip ADC, Legacy Industrial Replacement and Repair.
Industrial Sensor Signal Acquisition
The PIC16C711T-04/SS fits industrial sensor acquisition by combining an on-chip 8-bit 4-channel ADC with 13 GPIO, eliminating an external ADC IC and reducing BOM cost. Placed on a sensor interface board, it digitizes analog signals from temperature, pressure, or flow transducers and forwards the data via UART or I/O to a host controller. The 4 MHz clock yields a 200 ns instruction cycle, sufficient for 8-bit ADC sampling at typical industrial rates. Trade-off: OTP memory prevents field re-calibration, so calibration constants must be stored in a one-time fuse block or external EEPROM.

White Goods and Appliance Control
The PIC16C711T-04/SS is well-suited for white-goods control boards where a 4 MHz mid-range MCU, on-chip ADC, and low cost matter more than reprogrammability. It can read temperature sensors (NTC), drive relays and triacs through its 13 GPIO, and run a simple state-machine for washing machines, dishwashers, or microwave oven user interfaces. The 4 V to 6 V supply range aligns directly with rectified 5 V rails found in appliance power supplies. Compared with newer flash PIC16F1xxx parts, the OTP version is cheaper at high volume, justifying the one-time-programmed firmware flow.

Battery-Powered Instrumentation
The PIC16C711T-04/SS supports low-power instrumentation thanks to its CMOS process and ability to run at 4 MHz from a single 5 V rail. With sleep mode enabled between ADC samples, average current drops into the microamp range, suiting battery or solar-powered meters. The integrated ADC measures up to four analog channels, allowing multi-sensor configurations without external signal conditioning. Compared with newer nanoWatt PICs, this OTP variant is less efficient but cheaper; choose it when BOM cost outweighs long battery-life targets.

Automotive Body and Comfort Electronics
For non-safety automotive subsystems such as seat controllers, mirror adjusters, or HVAC blend-door actuators, the PIC16C711T-04/SS provides adequate compute and ADC capability at a competitive price point. Its 13 GPIO can drive small relays and read position sensors via the on-chip ADC. The wide 4 V to 6 V supply tolerates cranking transients typical of 12 V automotive systems. Limitation: commercial temperature grade (0 C to +70 C) restricts deployment to cabin modules; for under-hood use, select the PIC16C711T-04I/SS industrial-grade alternative.

Embedded Control Subsystem with On-Chip ADC
When a larger host processor needs a small, deterministic companion MCU for ADC scanning or motor control, the PIC16C711T-04/SS fits the role. It reads multiple analog signals (current, voltage, temperature) at the 4 MHz clock rate, applies digital filtering, and exchanges results with the host via SPI or UART. The PIC mid-range RISC core delivers predictable interrupt latency, an advantage over event-driven cores when deterministic sampling matters. Trade-off: OTP memory forces the host to handle field firmware revisions if the subsystem firmware needs updates.

Legacy Industrial Replacement and Repair
For maintenance and repair of older industrial equipment that originally used the PIC16C711 in OTP mode, the PIC16C711T-04/SS offers an exact functional match with tape-and-reel delivery suitable for small production batches. It restores the same 4-channel 8-bit ADC and 13 I/O configuration without requiring PCB redesign or firmware porting. Compared with transitioning to a flash MCU, using the same OTP part minimizes validation effort. Limitation: long-term availability is constrained by the NRND designation, so consider PIC16F716 for any new derivative designs.

Diferensiator Kunci
- Integrated 4-channel 8-bit ADC eliminates external ADC IC (vsPIC16C710T-04/SS)
- Commercial temperature grade is the lowest-cost tier of the family (vsPIC16C711T-04I/SS)
- Flash-based upgrade available with same peripheral set (vsPIC16F716)
Catatan Desain
Place a 100 nF ceramic decoupling capacitor as close as possible to the VDD pin (pin 20), with a bulk electrolytic (typically 10 uF to 47 uF) at the board's supply entry. For ADC noise-sensitive designs, add an additional 100 nF on the AVdd-style supply rail if used, and keep the analog and digital grounds tied at a single point near the MCU's VSS pins to avoid ground-loop noise.
Route the oscillator traces (OSC1/OSC2) short and guarded with a ground ring to minimize EMI pickup. Keep ADC input traces (RA0-RA3) away from switching nodes such as relay drivers; place a small RC filter (typically 1 kohm plus 100 pF) on each analog input if the source impedance exceeds the 10 kohm ADC recommended maximum. Avoid running digital signals parallel to the analog traces.
OTP memory on the PIC16C711 cannot be erased or rewritten, so firmware bugs become silicon bugs at programming time. Always validate firmware on a flash-based equivalent (PIC16F716 or PIC16C711 flash emulation) before committing to OTP programming. Also note that the MCLR pin (pin 1) must be pulled high through a 10 kohm resistor for normal operation; leaving it floating prevents the device from running.
Informasi Konformitas
PIC16C711T-04/SS is part of the legacy OTP PIC16C family which is generally non-RoHS due to the use of leaded solder finish on older lots; check the specific lot date code with your distributor. AEC-Q100 qualification is not applicable for the commercial temperature grade; for automotive systems the I-suffix industrial variant is typically required at minimum.
