PIC16LC711-04E/SO Übersicht
A microcontroller (MCU) is a single-chip computer containing a CPU, program memory (ROM/EPROM/Flash), working memory (RAM), and programmable peripherals. PIC microcontrollers use a Harvard RISC architecture with 14-bit wide instruction words, enabling most instructions to execute in a single 200ns instruction cycle at 20MHz. The PIC16C71x family sits in Microchip's mid-range MCU portfolio, targeting cost-sensitive analog and digital control applications where on-chip A/D conversion reduces external component count.
Key features include 1.75KB (1K x 14) of EPROM program memory, 68 bytes of data RAM, 13 individually direction-controlled I/O pins, an 8-bit A/D converter with multiple input channels, Brown-out Reset for reliable operation during supply droops, and a wide 2.5V to 5.5V operating range suited to battery-powered and 3.3V/5V mixed systems. The 'E' suffix denotes the extended (industrial) temperature grade and 'LC' indicates the low-power CMOS variant optimized for low Vdd operation.
The PIC16LC711-04E/SO uses a Harvard architecture with separate program and data buses, a 5-level deep hardware stack, and 35 single-word instructions. The 8-bit A/D converter shares pins with the digital I/O, configurable via the ADCON1 register. Timer1 can be incremented during sleep via an external crystal/clock, enabling real-time-clock functions without CPU intervention.
Typical applications include low-power sensor interfaces, battery management subsystems, industrial control front-ends, automotive body electronics, and analog signal conditioning nodes where the integrated A/D eliminates an external converter. The wide 2.5V-5.5V range also supports portable devices powered directly from lithium cells.
When designing with this part, observe the EPROM program memory one-time-programmable nature and place a 0.1uF decoupling capacitor close to VDD. Configure the A/D acquisition time according to source impedance, and ensure unused I/O pins are set as outputs low or inputs with internal pull-ups to minimize power consumption. The '04' speed grade indicates 4MHz maximum oscillator frequency.

Typische Anwendungen
PIC16LC711-04E/SO ist geeignet für 6 Anwendungs: Battery-Powered Sensor Interface, Industrial Control Front-End, Automotive Body Electronics, Analog Signal Conditioning Node, Home Appliance User Interface, Low-Voltage Portable Device Controller.
Battery-Powered Sensor Interface
The PIC16LC711-04E/SO's 2.5V to 5.5V wide Vdd range and 'LC' low-power CMOS process make it ideal for battery-powered sensor interface nodes running directly from a single lithium or two AA cells. The 1.75KB EPROM holds sensor calibration routines, while the 8-bit multi-channel A/D converter directly digitizes analog signals from temperature, pressure, or humidity transducers. The 13 I/O pins drive sensor excitation, status LEDs, and a low-power RF or UART link. Power dissipation drops below 1mA during A/D sampling and into the microamp range during sleep, making 200ns instruction cycles suitable for time-multiplexed channel scans. Pair with a 32kHz external crystal driving Timer1 in sleep mode to maintain real-time clock scheduling while CPU is halted.

Industrial Control Front-End
The PIC16LC711-04E/SO's extended -40C to +125C temperature range suits it for industrial control front-ends exposed to factory ambient conditions. The 8-bit A/D converter with multiple input channels reads 4-20mA loop signals via external current-sense resistors or 0-10V process variables via resistor dividers, eliminating external ADC ICs. The three timer modules (Timer0 8-bit, Timer1 16-bit, Timer2 8-bit with PWM) support quadrature decoding, event counting, and PWM outputs for proportional valve or heater control. Brown-out Reset (BOR) ensures reliable restart after supply droops on long industrial wiring. EPROM-based code is one-time programmable but production-stable; pair with external EEPROM (24LC02) for configuration storage and run-time calibration constants.

Automotive Body Electronics
While not AEC-Q100 qualified, the PIC16LC711-04E/SO's extended -40C to +125C temperature range and robust 8-bit RISC architecture suit non-safety automotive body applications such as interior lighting controllers, seat position memories, and accessory delay timers. The 13 I/O pins drive relay coils and read switch contacts with internal weak pull-ups. The integrated A/D reads potentiometer wiper positions for analog trim controls, while Timer1 with external 32.768kHz crystal maintains real-time clock for delayed-off accessory features. Note that AEC-Q100 automotive projects should use the PIC16F1xxx automotive family with Q suffixes; this part is acceptable only for non-safety chassis or aftermarket modules.

Analog Signal Conditioning Node
The PIC16LC711-04E/SO's integrated 8-bit multi-channel A/D converter and 13 I/O pins make it ideal as an analog signal conditioning node digitizing multiple transducer outputs simultaneously. Place between op-amp signal conditioning front-ends and a host controller via UART or SPI; the PIC16LC711 provides local A/D conversion, linearization, and digital filtering at up to 4MHz clock speeds. The 1.75KB EPROM stores calibration lookup tables for thermistor or RTD linearization, while 68 bytes of RAM buffers the converted samples before transmission. Brown-out Reset ensures valid data acquisition during noisy supply conditions typical in motor or relay systems. The 200ns instruction cycle handles digital filtering algorithms such as moving averages or simple IIR filters.
Empfohlen
Home Appliance User Interface
The PIC16LC711-04E/SO's 13 I/O and integrated A/D suit cost-sensitive home appliance user interface modules such as washing machine control panels, microwave keypads, and thermostat displays. The 8-bit A/D reads rotary encoder wiper voltages, resistive touch panels, or NTC thermistors for temperature feedback. PWM from Timer2 dims LED backlights and segment indicators. The 35-instruction RISC core simplifies coding for button debouncing, display multiplexing, and EEPROM-backed user settings. The 18-pin SOIC footprint fits compact control boards and the extended temperature grade handles hot appliance environments up to +125C near heating elements.
Empfohlen
Low-Voltage Portable Device Controller
The PIC16LC711-04E/SO's 'LC' low-voltage variant operates down to 2.5V, enabling direct lithium coin-cell or single-cell alkaline battery operation in portable devices like wireless sensor tags, remote controls, or simple handheld instruments. The low-power CMOS process minimizes sleep current to single-digit microamps, while the integrated A/D can wake the CPU on threshold-crossing sensor events. 1.75KB EPROM holds application firmware for periodic measurement and RF transmission scheduling, with 13 I/O controlling RF module chip-select, status LEDs, and user buttons. The 4MHz clock supports real-time response while keeping dynamic current below 2mA active - acceptable for coin-cell designs with duty-cycled operation.

Wichtigste Unterscheidungsmerkmale
- Extended temperature range for industrial environments (vs. PIC16LC711-04/SO)
- Low-power CMOS process for battery operation (vs. PIC16C711-04E/SO)
- Drop-in pin-compatible with commercial grade (vs. PIC16C711-04/SO)
Designhinweise
The PIC16LC711-04E/SO 'LC' variant operates from 2.5V to 5.5V. Place a 0.1uF ceramic decoupling capacitor as close as possible to the VDD pin (pin 11) and a bulk capacitor (10uF or larger) at the supply input. For battery applications, a low-Iq LDO such as MCP1700 (~1.6uA quiescent) ensures the regulator's idle current does not exceed the MCU's sleep current. Brown-out Reset (BOR) must be enabled in the configuration word to ensure defined restart behavior during supply droops typical in motor or relay-driven systems.
Route the MCLR (pin 1) signal with a 10k pull-up resistor to VDD and place the ICSP programming connector footprint for in-circuit programming access. The SOIC-18 package requires standard 1.27mm pitch SOIC land pattern with 0.6mm pad width. Keep analog input traces short and away from digital switching signals to minimize A/D converter noise coupling. The MCLR capacitor (typically 100nF) should be located close to the pin to filter noise that could trigger spurious resets.
Do not exceed 4MHz oscillator frequency on the '04' speed grade, even though the LC process technically supports higher - the timing parameters at higher frequencies are not characterized. Configure unused I/O pins as outputs low or inputs with internal weak pull-ups enabled to minimize power consumption and prevent floating-input oscillation. EPROM one-time-programmable memory cannot be erased - ensure firmware is fully validated in PIC16F716 equivalent or socketed EPROM prototype before committing to masked production. The A/D converter requires adequate acquisition time based on source impedance per DS30561A Table 9-1.
