PIC16LC711T-04/SS 概要
A microcontroller (MCU) is a single-chip computer that combines a CPU, memory, and peripherals on one die. The PIC16C71X family belongs to the broader RISC-microcontroller category, and more specifically the PIC16CXX mid-range architecture with a 14-bit instruction word. These parts sit above 4-bit/8-bit microcontrollers and below 32-bit ARM Cortex-M MCUs in terms of complexity, and they integrate an analog ADC—a feature historically distinguishing the '71X sub-family from earlier PIC16C55/C56 devices that lacked conversion capability.
Key features include 1.75 KB OTP program memory (one-time programmable, not reprogrammable), 68 bytes of SRAM, a 4-channel 8-bit A/D converter, 13 bidirectional digital I/O pins, and a watchdog timer with its own on-chip RC oscillator for reliable operation. The device supports in-circuit serial programming (ICSP) via two pins, enabling production-line programming without removing the chip from the board. The fully-static CMOS core allows the clock to be stopped and restarted, enabling low-power standby operation in battery-powered designs.
The PIC16C71X architecture uses a Harvard design with separate program and data buses, a 14-bit instruction word, and 35 single-word instructions—most executed in a single instruction cycle. The integrated 8-bit ADC multiplexes up to 4 analog inputs (RA0–RA3) through the PORTA pins, with conversion times determined by the ADC clock source. The OTP memory cannot be erased or rewritten, so this part targets high-volume consumer and industrial applications where the program is finalized at production.
Typical applications include analog-sensor interface modules (temperature, light, pressure), low-cost motor-control signal conditioning, industrial process-control front-ends with on-board conversion, appliance control boards reading analog potentiometers or transducers, and battery-powered measurement instruments requiring 3 V operation. The 4 MHz clock and small memory footprint suit cost-sensitive embedded designs that need a moderate amount of analog signal handling without external ADC components.
When designing with this part, choose external crystal or RC oscillator components carefully—the oscillator type (XT, HS, RC) directly affects the maximum instruction throughput. Because OTP memory cannot be reprogrammed, plan for code-version control via part-number suffixes (PIC16LC711T-04I/SS for industrial temperature range, etc.). Provide adequate decoupling (0.1 µF + bulk) on VDD/VSS adjacent to the package.

主な用途
PIC16LC711T-04/SS の用途: 6 件s: Analog Sensor Interface Module, Industrial Process Control Front-End, Appliance Control Board, Battery-Powered Measurement Instrument, Automotive Sensor Conditioning, Educational / Hobbyist Embedded Platform.
Analog Sensor Interface Module
The PIC16LC711T-04/SS is well-matched to analog sensor front-ends where a low-cost MCU must digitize one to four transducer channels and apply digital filtering or threshold logic in firmware. Its integrated 4-channel 8-bit ADC, 13 digital I/O, and 68 bytes of RAM are sufficient for sampling resistive sensors (thermistors, photoresistors, potentiometers) at modest rates while leaving enough headroom for linearization tables. Designers typically run the ADC clock at FOsc/32 to achieve acceptable conversion times. The 20-SSOP footprint remains compact for hand-held instrumentation housing, and pin-compatible Flash successors such as PIC16F870-I/SS allow easy migration when re-programmability becomes important during development.
おすすめ
Industrial Process Control Front-End
In industrial control boards that digitize analog set-points and drive digital outputs, the PIC16LC711T-04/SS delivers deterministic single-cycle instruction execution at 4 MHz, well-suited to PID-style control loops running on the device. The mid-range core's 14-bit instruction word allows compact encoding of branch-and-comparison sequences, and the integrated A/D converter eliminates the need for an external ADC chip on crowded PLC-style backplanes. The 20-SSOP package offers reasonable thermal performance and is compatible with reflow processes. Designers should still place 0.1 µF + 10 µF decoupling as close to VDD/VSS as possible and use the watchdog timer to recover from electrical transients common on factory floors.
おすすめ
Appliance Control Board
White-goods and small-appliance control boards commonly embed a single 8-bit MCU to read user potentiometers, push-buttons, and a few sensors, then drive relays or TRIACs. The PIC16LC711T-04/SS fits this profile with 1.75 KB of OTP memory (sufficient for fixed-function appliance firmware) and 13 digital I/O lines that map to relay drivers, status LEDs, and an analog set-point knob. The wide 3.0 V to 5.5 V supply simplifies mixed-rail designs where the MCU must share a 5 V supply with analog conditioning circuitry. Application notes from Microchip illustrate driving TRIACs and zero-cross detection using the same external interrupt pin, a pattern that maps directly onto this part's RB0/INT pin.
おすすめ
Battery-Powered Measurement Instrument
Battery-powered measurement instruments—such as handheld thermometers, light meters, and small portable data loggers—benefit from the PIC16LC711T-04/SS's wide 3.0 V to 5.5 V supply range and fully-static CMOS core that allows the oscillator to be stopped during sleep to extend battery life. The on-chip 8-bit ADC digitizes readings from low-power sensors while the MCU is awake, and the watchdog timer re-awakens the part from sleep when needed. Drawing the sensor stack around low-quiescent regulators such as MCP1700 makes total system quiescent current manageable. LCD drive is typically handled via external shift registers given the limited pin count.
おすすめ
Automotive Sensor Conditioning
Although not AEC-Q100 qualified, the PIC16LC711T-04/SS has historically been used in non-safety automotive subsystems such as body-electronics sensor conditioning, where the integrated 8-bit ADC and modest I/O count are sufficient. Pin compatibility with the PIC16F870-I/SS makes the path to AEC-Q100 grades straightforward if the application scope later expands into safety-critical territory. EMI considerations still apply: bypass capacitors on VDD/VSS, watch for ground bounce on relay-driven systems, and use the watchdog timer to reset the part after voltage transients. A careful review of Microchip errata for the PIC16C71X family is recommended before committing to a high-volume automotive design.
おすすめ
Educational / Hobbyist Embedded Platform
The PIC16LC711T-04/SS remains useful in educational settings and hobbyist projects where learners explore 8-bit MCU fundamentals, ADC integration, and assembly-level programming on the PIC mid-range architecture. Its small 14-bit instruction set (35 single-word instructions) is approachable for first-time learners, and the 20-SSOP package fits on commonly available breakout boards and training kits. In-circuit serial programming (ICSP) via two pins allows repeated program-and-test cycles during development. For new educational kits, however, Microchip's current PIC16F1xxx family in similar 20-SSOP packages offers Flash-based reprogramming, which simplifies classroom workflows considerably.

主な差別化要因
- Integrated 8-bit ADC eliminates external ADC chip （vs PIC16LC710T-04E/SS (no ADC on PIC16LC710 family))
- Reprogrammable Flash replaces one-time-programmable OTP （vs PIC16LC711T-04/SS (this part, OTP) vs. PIC16F870-I/SS (Flash))
- Wider supply voltage tolerance for mixed-voltage designs （vs PIC16F870-I/SS (2.0 V to 5.5 V) vs. PIC16LC711T-04/SS (3.0 V to 5.5 V))
設計ノート
Decouple VDD with a 0.1 µF ceramic capacitor placed within 5 mm of the VDD/VSS pins, with an additional 10 µF bulk capacitor on the same supply rail. The PIC16LC711T-04/SS supply voltage range is 3.0 V to 5.5 V; ADC accuracy is sensitive to VDD ripple, so feeding VDD from a low-noise regulator such as MCP1700 improves the effective number of bits by 1 to 2 LSBs over a noisy 5 V rail.
Because the PIC16LC711T-04/SS uses OTP program memory, firmware bugs cannot be patched in the field — every shipped unit carries the original code. Engineering teams should fully validate firmware on a Flash equivalent (such as PIC16F870-I/SS in the same 20-SSOP footprint) before committing to OTP production quantities. Also confirm the appropriate oscillator configuration bits (XT, HS, LP, RC) match the external crystal or resonator selected.
Route the crystal or resonator traces short and symmetric, with a grounded guard ring if possible, to minimize EMI pickup that can cause clock glitches on OSC1/OSC2. The MCLR/VPP pin should be tied to VDD via a 10 kΩ pull-up and a 100 nF capacitor to ground for ICSP programming; this allows production-line programming without removing the chip from the board.
コンプライアンス情報
