PIC16LC716T-04I/SS - 8-bit 4MHz MCU, 3.5KB OTP, 20-SSOP | Microchip
MPN: PIC16LC716T-04I/SS ✓ Hoạt độngPIC16LC716T-04I/SS Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (program + data), and programmable peripherals on one die. Within the broader semiconductor taxonomy, the PIC16LC716 sits under: microcontroller -> embedded controller -> 8-bit MCU -> CMOS RISC MCU -> Microchip PIC16 family. The 'LC' suffix denotes the low-voltage CMOS variant (operating down to ~2.5V), while the 'T' suffix indicates Tape & Reel packaging and 'I' specifies the industrial temperature grade (-40C to +85C).
Key features include 35 single-word instructions (all single-cycle except program branches), a 4 MHz maximum operating frequency giving 200 ns instruction cycles, integrated Brown-out Reset (BOR), Power-On Reset (POR), Watchdog Timer (WDT), and PWM output. The device operates from 2.5V to 5.5V across the industrial temperature range.
The PIC16LC716T-04I/SS uses Microchip's classic Harvard RISC architecture with separate program and data buses, which is why the program memory word is 14 bits wide (compared to the 8-bit data bus). This architecture delivers deterministic interrupt latency and predictable instruction timing, ideal for hard-real-time control loops such as motor control and sensor sampling.
Typical applications include low-power embedded control, sensor signal conditioning, PWM-driven LED drivers, small motor control, white-goods appliance control, and battery-powered instrumentation. The industrial temperature grade makes it suitable for outdoor or factory-floor deployments.
When designing with this device, note that the '04' speed suffix corresponds to a 4 MHz oscillator limit and the /SS suffix confirms SSOP-20 footprint (5.30 mm body width). Code developed for this OTP device cannot be reprogrammed, so engineers typically prototype with the windowed (UV-erasable) PIC16LC716 counterpart or the flash-based PIC16F716.

Ứng dụng tiêu biểu
PIC16LC716T-04I/SS phù hợp cho 6 Áp dụngs: Sensor Signal Conditioning, PWM LED Driver Control, Small Motor Control (Brushed DC), White-Goods Appliance Control, Battery-Powered Instrumentation, Automotive Body Electronics (Auxiliary).
Sensor Signal Conditioning
The PIC16LC716T-04I/SS is well-suited for low-power sensor signal conditioning front-ends. Its integrated 8-bit A/D converter (sampled via the AN0-AN3 channels) provides adequate resolution for thermistor, photodiode, or strain-gauge readouts, while the 35-instruction RISC core executes linearization and averaging loops within the 200 ns single-cycle budget. At 2.5 V to 5.5 V operation, the part can run directly from a 3.3 V regulated rail or a 2xAA battery pack, eliminating the need for an external boost converter. The industrial -40 C to +85 C range covers outdoor environmental sensor pods and HVAC duct probes. Place a 100 nF decoupling cap adjacent to VDD (pin 20) and a 10 kohm pull-up on MCLR (pin 1) for reliable brown-out-reset behavior.

PWM LED Driver Control
The PIC16LC716T-04I/SS provides a Capture/Compare/PWM (CCP) peripheral on RC2/CCP1 capable of driving LED dimming loops at up to several kHz PWM frequency with 10-bit resolution. The 4 MHz instruction rate is fast enough to service multiple PWM channels via software bit-banging when additional LED strings are required. Operating from 2.5 V to 5.5 V, the part can directly interface to constant-current LED driver ICs such as the TLC5940 or simple MOSFET low-side switches. The integrated Brown-out Reset prevents flicker during brown-out events, and the Watchdog Timer recovers the MCU from software faults - both critical for unattended lighting installations. For cost-optimized fixed-brightness signage, the OTP architecture eliminates per-unit flash programming costs.

Small Motor Control (Brushed DC)
For small brushed-DC motor control in toys, appliances, or HVAC dampers, the PIC16LC716T-04I/SS offers sufficient compute horsepower: the CCP peripheral generates the PWM command signal, while firmware-implemented PI loops regulate speed or torque at sample rates above 1 kHz. The 128-byte RAM accommodates state-machine variables and PID history, and the 3.5 KB OTP program memory holds control tables and lookup curves. Industrial temperature rating supports under-hood automotive auxiliary pumps and outdoor fan drives. Use the WDT to safely reset the MCU on stalled-rotor faults. Note: for sensorless BLDC or FOC algorithms, a dsPIC33 migration is recommended.

White-Goods Appliance Control
Embedded control for washing machines, dishwashers, and microwave ovens is a classic fit for the PIC16LC716T-04I/SS. The MCU reads user panel buttons via the A/D channels (resistor-ladder keypad), drives 7-segment or LCD displays through software multiplexing, and times relay outputs for pumps, valves, and heaters. Brown-out Reset and Watchdog Timer satisfy the safety-critical reliability requirements of household appliances. The OTP 3.5 KB program memory holds state-machine firmware with no field-upgrade path needed for cost-sensitive consumer products. The SSOP-20 footprint with 5.30 mm body is well-suited to high-density appliance control boards.

Battery-Powered Instrumentation
Low-voltage CMOS operation from 2.5 V to 5.5 V and the LC-family low-quiescent architecture make the PIC16LC716T-04I/SS a good choice for battery-powered instrumentation - handheld multimeters, portable data loggers, or wireless sensor nodes. Two AA alkaline cells (3.0 V nominal) can power the MCU directly without a boost converter, and Sleep mode current drops to microamp levels when the WDT is disabled. The ADC monitors battery voltage for low-cell cutoff, while firmware-implemented SPI or I2C bit-banging interfaces to external flash or radio modules. Tape & Reel packaging supports automated SMT assembly of compact handheld enclosures.

Automotive Body Electronics (Auxiliary)
While the PIC16LC716T-04I/SS is not AEC-Q100 qualified, its industrial -40 C to +85 C range and integrated peripherals make it a cost-effective choice for non-safety automotive body applications: ambient lighting controllers, seat-position memory modules, mirror adjusters, and accessory timers. The CCP/PWM peripheral drives LED strings or small DC motors, while the ADC reads potentiometer or Hall-effect sensor inputs. Brown-out Reset handles load-dump transients on the 12 V automotive bus after external regulation. For safety-critical or under-hood applications (>-40 C to +125 C, AEC-Q100), an automotive-qualified PIC16 variant must be selected.

Ghi chú thiết kế
Place a 100 nF ceramic decoupling capacitor as close as possible to VDD (pin 20) and a bulk 10 uF tantalum or ceramic capacitor on the same node to suppress switching transients. The PIC16LC716T-04I/SS operating range is 2.5 V to 5.5 V; verify the regulator ripple stays below 50 mVpp at full load to avoid spurious ADC readings on the AN0-AN3 channels. Brown-out Reset is enabled by default configuration bit; do not disable it for production firmware, as this protects against code mis-execution during supply droops.
Three common pitfalls to avoid with the PIC16LC716T-04I/SS: (1) The 'T' suffix indicates Tape & Reel - do NOT order the 'T' variant for hand-rework or breadboarding; use the tube-shipped PIC16LC716-04I/SS instead. (2) OTP memory cannot be reprogrammed - a single misprogramming step bricks the part. Always prototype with the flash-based PIC16F716-I/SS or windowed PIC16LC716 variant before committing to OTP volume orders. (3) The MCLR pin (pin 1) MUST have a 10 kohm pull-up to VDD; leaving it floating causes intermittent resets.
Route the oscillator traces (OSC1 pin 8 / OSC2 pin 9) as short as possible and guard them with a ground ring to reduce EMI susceptibility. If using a crystal oscillator, place the crystal within 5 mm of the MCU and add 15-33 pF load capacitors to ground per the datasheet crystal table. Avoid routing high-speed digital signals (PWM, INT) parallel to the oscillator traces for more than 5 mm to prevent capacitive crosstalk into the clock signal.
When using the ADC channels for sensor readout, add an RC low-pass filter (1 kohm + 100 nF, fc ~1.6 kHz) at each analog input to reject PWM switching noise coupled through the power supply or PCB ground bounce. The internal 8-bit ADC has a recommended source impedance below 10 kohm for full accuracy; higher-impedance sensors (e.g., thermistor dividers above 50 kohm) require an external op-amp buffer. Acquire multiple ADC samples and average in firmware to improve SNR beyond the raw 8-bit resolution.
