PIC16C716-04E/SS Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, and configurable peripherals on one die. PIC microcontrollers from Microchip use a modified Harvard architecture with separate program and data buses, an accumulator-based ALU, and a RISC instruction set where most instructions execute in a single instruction cycle. The PIC16C716 sits in the PIC16 mid-range family and uses the 14-bit instruction word subset.
The device operates from 4 MHz and accepts a supply voltage between 4.0 V and 5.5 V. On-chip peripherals include an 8-bit Timer0 with an 8-bit prescaler, a multi-channel 8-bit analog-to-digital converter (ADC), and Brown-out Reset (BOR) circuitry. The 'C' designation indicates the OTP EPROM program memory variant, while the '04' speed suffix marks the 4 MHz maximum clock. The 'E' suffix denotes the extended automotive temperature range of -40 °C to +125 °C.
Typical applications include automotive body controllers, sensor signal conditioning, simple motor control loops, and industrial white-goods subsystems where small form factor, on-chip ADC, and BOR supervision eliminate external components. The 20-pin SSOP footprint is also commonly used in handheld instrumentation and low-cost appliance control boards.
When laying out a board with the PIC16C716-04E/SS, place the 0.1 µF decoupling capacitor within 3 mm of the VDD pin, route MCLR through a 10 kΩ pull-up, and provide a short, guarded ground return for the analog AVSS/AVDD pair. The internal oscillator or an external crystal on OSC1/OSC2 should be kept clear of switching traces to avoid corrupting the ADC reference.

Typical Applications
PIC16C716-04E/SS is suitable for 6 applications: Automotive Body Controller, Sensor Signal Conditioning Node, Appliance Control Board, Handheld Instrumentation, Simple Motor Speed Controller, Industrial Lighting Controller.
Automotive Body Controller
The PIC16C716-04E/SS fits automotive body control modules because its -40C to +125C automotive temperature grade and on-chip Brown-out Reset tolerate harsh electrical environments. With 13 I/O pins and an 8-bit multi-channel ADC, it can read multiple switch and sensor inputs (door switches, light sensors, temperature probes) and drive relay or LED outputs without external glue logic. The 3.5 KB OTP memory holds typical body-comodule code for central locking, lighting delay, and wiper control. Designers appreciate that the 20-pin SSOP package consumes less than 30 mm of board length, freeing space in door-module PCBAs.
Recommended
Sensor Signal Conditioning Node
The 8-bit multi-channel ADC on the PIC16C716-04E/SS supports up to five analog input channels (RA0-RA3, RA5), enough to read thermistor, photodiode, or pressure-sensor bridges in a sensor-conditioning node. With 3.5 KB OTP, a designer can implement linearization, averaging, and threshold-alarm logic on-chip. The 4 MHz clock provides roughly 1 µs ADC conversion time, sufficient for low-bandwidth industrial telemetry at sub-1 kHz sampling rates. Combined with the 20-pin SSOP, this fits inside compact sensor housings on factory floors.
Recommended
Appliance Control Board
The PIC16C716-04E/SS is widely deployed in white-goods control boards for washing machines, dishwashers, and microwave ovens because the OTP EPROM secures the algorithm against reverse engineering. The 13 I/O drive keys, LEDs, triac interfaces, and buzzer loads; the 8-bit ADC reads temperature, level, and turbidity sensors. The on-chip Brown-out Reset prevents latch-up during brown-out events common with motor inrush. The automotive-grade temperature range allows the same firmware to ship in commercial and entry-level appliance lines.
Recommended
Handheld Instrumentation
Battery-powered handheld instruments such as digital multimeters, tachometers, and remote controls benefit from the PIC16C716-04E/SS compact SSOP-20 footprint and 4 MHz low-speed operation. The 14-bit instruction set executes most instructions in one cycle, so a 4 MHz clock delivers roughly 1 MIPS, sufficient for keypad debouncing, LCD multiplexing, and one-shot measurements. The internal oscillator option eliminates two external crystals, reducing BOM cost and shrinking PCB area. The 128-byte RAM is adequate for stack and a few small buffers in low-duty-cycle measurement flows.
Recommended
Simple Motor Speed Controller
Low-cost DC and universal motor controllers in fans, pumps, and small appliances commonly use the PIC16C716-04E/SS to generate PWM via software bit-banging on Timer0, then drive a triac or MOSFET gate. The 8-bit ADC reads back EMF or tachometer pulses to close the speed loop; 13 I/O pins give enough channels for direction control, brake, and tach feedback. With 3.5 KB OTP, designers can implement soft-start, current-limit, and stall-detection algorithms. The SSOP-20 allows the controller to sit on the same board as the power stage without consuming significant area.
Recommended
Industrial Lighting Controller
Lighting controllers for signage, architectural dimming, and emergency-lamp drivers use the PIC16C716-04E/SS to schedule on/off cycles and read ambient light sensors through the on-chip 8-bit ADC. The 13 I/O pins control multiple MOSFET low-side switches for LED strings; the 4 MHz clock is fast enough for 1 kHz PWM dimming without flicker. The extended temperature grade supports outdoor enclosures, and the on-chip Brown-out Reset keeps the controller in a known state across cold-soak power events. OTP secures the lighting schedule against field tampering.

Key Differentiators
- Automotive temperature grade in same SSOP-20 footprint (vs PIC16C716-04I/SS)
- Identical silicon, factory-tape-and-reel packaging (vs PIC16C716T-04E/SS)
- Flash replacement with same peripherals and footprint (vs PIC16F716-I/SS)
Design Notes
Place a 0.1 µF ceramic decoupling capacitor within 3 mm of the VDD pin (pin 20) and a bulk 10 µF tantalum or aluminum capacitor on the same supply rail. The PIC16C716-04E/SS draws peak transient currents during ADC conversion; without local decoupling, AVSS/AVDD ripple can corrupt ADC readings. Tie AVSS to the same ground as VSS at a single point near the IC to avoid ground loops. The on-chip Brown-out Reset asserts at approximately 4.0 V falling, so a clean 5 V rail is essential for reliable BOR behavior.
Route the MCLR pin (pin 1) through a 10 kΩ pull-up resistor to VDD, and add a 100 nF capacitor to ground to filter fast transients on the reset line. Place the crystal or resonator as close as possible to OSC1 (pin 9) and OSC2 (pin 10), with a guarded ground plane beneath to limit coupling into the analog ADC inputs. Keep switching traces (PWM, relay drivers) at least 5 mm away from RA0-RA5 analog traces, and consider a guard ring around AVSS for noisy motor-control layouts.
Do not assume OTP parts can be re-programmed - the PIC16C716-04E/SS uses one-time-programmable EPROM and a single high-voltage programming pulse permanently sets each bit. Verify your hex image before contacting a gang programmer. The 'E' suffix denotes the automotive -40C to +125C grade; using the wrong grade in an under-hood application can cause field failure. Also note that pin 18 is no-connect (NC) in the SSOP-20 layout and must be left floating - some third-party footprints incorrectly assign a function to this pin.
