PIC16F716-E/P Overview
An 8-bit flash microcontroller is a single-chip computer that integrates CPU core, non-volatile program memory, RAM, peripherals and interrupt logic into one package. Within the broader semiconductor taxonomy, an MCU belongs to the microcontroller family, which itself is a subset of microcomputers and ultimately of integrated circuits. The PIC16F716 belongs to the mid-range PIC16 family and uses Microchip's Harvard RISC architecture with only 35 single-word instructions, giving it the simplicity of a legacy 8-bit core while still offering on-chip ADC, PWM, timers and flash self-programming. This combination places it above older EPROM/ROM PICs in flexibility and below the PIC18 and dsPIC families in raw performance and memory.
Key features include 200 ns instruction execution at 20 MHz, 3.5 KB flash program memory with self-write capability, 128 bytes of RAM, a 10-bit prescaler shared between Timer0 and the WDT, two 8-bit timers plus one 16-bit timer, the Enhanced CCP module for half-bridge, full-bridge and single-output PWM, and four 8-bit ADC channels with selectable reference. The -E suffix indicates the extended industrial temperature grade, and the /P suffix identifies the 18-pin PDIP package.
Typical applications include advanced A/D-based designs in automotive sensor conditioning, white-goods and appliance motor drives, industrial process control, lighting ballasts, and cost-sensitive consumer products that need PWM plus analog sensing but not USB or CAN. The wide 2.5 V-5.5 V supply range also simplifies battery and 5 V-rail designs.
When laying out a PIC16F716 design, route the MCLR/VPP line with a 10 kΩ pull-up and a decoupling capacitor of about 0.1 µF to VDD, keep analog traces short and add a 10 µF bulk capacitor on VDD near the device. Choose the oscillator mode early, because HS vs XT vs INTOSC impacts EMI and start-up time.

Typical Applications
PIC16F716-E/P is suitable for 6 applications: Automotive Sensor A/D Conditioning, BLDC / Half-Bridge Motor Drive, Industrial Process Control, Lighting Ballast Control, White-Goods and Appliance Control, Cost-Sensitive Remote Controls and Consumer Toys.
Automotive Sensor A/D Conditioning
The PIC16F716-E/P's 4 channels of 8-bit ADC and 13 I/O lines suit automotive sensor-conditioning modules that read potentiometers, thermistors and simple analog switches. The 20 MHz core gives 200 ns instruction time, so the MCU can complete an 8-bit conversion result, average several samples and update a PWM output before the next sensor event, all while the 2.5-5.5 V VDD range tolerates cranking transients on 12 V automotive rails. Placed near the sensor cluster with 0.1 µF VDD decoupling, it eliminates an external ADC IC. Unlike larger PIC18F devices it adds no cost for unused 10-bit ADC resolution, so the BOM stays lean for AEC-grade applications.
Recommended
BLDC / Half-Bridge Motor Drive
The PIC16F716's Enhanced CCP module supports half-bridge, full-bridge and single-output PWM with programmable dead-band control, enabling direct drive of small three-phase brushless-DC or two-phase brushed motor half-bridges without an external PWM controller. Combined with the 4-channel 8-bit ADC for back-EMF or current sensing and 20 MHz throughput, it can run sensorless commutation tables and torque-control loops at modest RPM. The /P PDIP package simplifies prototype fan or pump motor boards, while the 2.5-5.5 V VDD range accepts 3.3 V logic-level gate drivers directly.
Recommended
Industrial Process Control
The PIC16F716-E/P fits industrial process-control boards where 4 analog inputs must be sampled, averaged and used to drive a PWM actuator or relay output. The 3.5 KB flash accommodates a small RTOS-style main loop with ADC, PWM, UART and I/O tasks, while the 128-byte RAM holds several hundred filtered samples. The -40 to +125 °C extended industrial temperature rating lets the board live inside an enclosure near a motor or heater. Unlike a pure logic-only 8-bit MCU, it integrates the ADC on-chip and cuts the BOM cost by removing a separate analog front-end.
Recommended
Lighting Ballast Control
Lighting ballasts for fluorescent, HID and LED arrays often need a small MCU that can run a PWM dim curve, monitor lamp current via an ADC channel and handle power-factor or burst-mode control. The PIC16F716's Enhanced CCP generates the dim PWM while the 4-channel 8-bit ADC reads lamp current, voltage and temperature. The 20 MHz instruction rate keeps the control loop sub-millisecond, and the 2.5-5.5 V VDD range works from rectified 5 V and 3.3 V rails without an extra LDO. The /P PDIP package simplifies hand-rework in field-serviceable fixtures.
Recommended
White-Goods and Appliance Control
Washing machines, microwave ovens, induction cooktops and similar white-goods need an MCU with mixed analog and PWM capability and a temperature grade that survives a hot enclosure. The PIC16F716-E/P delivers 4 ADC channels for temperature, level and door-state sensors and an Enhanced CCP for driving buzzer, relay or triac-control PWM. The -40 to +125 °C extended grade handles under-cabinet thermal stress, and 3.5 KB flash is enough for menu logic, fault detection and timing routines. It replaces older PIC16F7x OTP parts with field-updateable flash while keeping the same development environment.
Recommended
Cost-Sensitive Remote Controls and Consumer Toys
The PIC16F716-E/P is also useful in low-cost consumer products such as remote controls, electronic toys, simple timers and educational kits where 13 I/O, a 4-channel ADC and an Enhanced CCP deliver functionality at sub-US-$2 BOM. The 3.5 KB flash fits small state-machine firmware, while the 128-byte RAM covers transient variables. The -40 to +125 °C grade prevents field failures in cars, kitchens and outdoor enclosures. The /P PDIP package is hobbyist-friendly for breadboarding and low-volume makerspace projects.

Key Differentiators
- Higher 8-bit ADC channel count than baseline 14-pin PIC16F devices (vs PIC16F630-E/P)
- Enhanced CCP supports half-bridge and full-bridge PWM with dead-band (vs PIC16F628A-I/P)
- Lower cost and smaller flash than PIC16F690 for simpler A/D applications (vs PIC16F690-I/P)
Design Notes
Estimated: at VDD = 5 V and 20 MHz clock, the PIC16F716-E/P core and peripherals draw about 10-15 mA typical; add a 10 µF bulk plus a 0.1 µF ceramic decoupling cap within 5 mm of pins 17 (VDD) and 16 (VSS). Place the bulk capacitor near the IC and tie its ground return directly to the VSS pin to avoid ground bounce. For battery-powered designs switching to INTOSC at 4 MHz, expect roughly 1-2 mA, which the datasheet (41206A) confirms in the electrical characteristics table.
Route the MCLR/VPP pin (pin 1) with a 10 kΩ pull-up to VDD and a 100 nF cap to VSS; this is mandatory for in-circuit serial programming (ICSP) and stable resets. Keep analog traces (RA0-RA3) short and away from PWM switching signals on RC1/RC2 to limit ADC noise. If using the Enhanced CCP, place the PWM outputs near the connector edge and route grounds in a star pattern back to the VSS pin to handle the high di/dt transitions cleanly.
Do not assume the PIC16F716 ECCP PWM module behaves like the basic CCP on smaller PICs; configure the PWM steering bits in the PSTRCON register and set the dead-band delay via ECCP1DEL before enabling the PWM output, or the H-bridge will shoot through. The 8-bit ADC channels share the upper PORT A pins with digital I/O; the PCFG bits in ADCON1 must be cleared correctly or the digital Schmitt buffers will distort analog readings. Finally, the 'E' temperature grade is required for under-hood automotive - the 'I' grade fails near +125 °C.
When using the external oscillator mode, keep the crystal or resonator within 5 mm of pins OSC1 (pin 18) and OSC2 (pin 1 on adjacent packages; consult the package drawing for SOIC), with a solid ground plane underneath and short traces to avoid EMI and start-up failures. The datasheet (41206A) recommends 15-33 pF load capacitors for HS crystal mode and 100-470 kΩ feedback for ceramic resonators. Place a 100 Ω series resistor on MCLR only if the design is exposed to ESD strikes; otherwise omit it to keep the reset edge sharp.
Estimated: when the Enhanced CCP drives a half-bridge at 20 kHz PWM, peak slew rates exceed 1 V/ns, so route the PWM traces over an unbroken ground reference and avoid crossing analog input traces. Add 100 Ω source-series resistors on the PWM outputs if EMI is measured to exceed margins. Keep ADC traces short (≤25 mm) and bypass the analog supply pin (AVDD) with 10 µF + 100 nF if the board has separate analog and digital rails.
Compliance Information
RoHS and lead-free per Microchip product page. AEC-Q100 status for the -E extended industrial -40 to +125 °C grade is referenced in automotive design contexts but the exact -E/P ordering code should be confirmed against Microchip's automotive portfolio listing. Halogen-free status not stated explicitly in the data.
