PIC16C716T-04/SO - 8-bit 4MHz OTP MCU, 3.5KB, 13 I/O | Microchip
MPN: PIC16C716T-04/SO ✗ Cuối đờiPIC16C716T-04/SO Tóm tắt
An OTP-based PIC microcontroller is a member of the PIC16 family of 8-bit microcontrollers, part of the broader Microchip PIC (Peripheral Interface Controller) product family. Within the embedded system hierarchy, a PIC16C7xx OTP MCU belongs to the Microcontroller Unit (MCU) class, itself a sub-category of microcontrollers within Integrated Circuits > Microcontrollers. These devices execute a reduced instruction set (RISC) of 35 single-word instructions, delivering deterministic 200 ns instruction cycles at the maximum 20 MHz clock input - a fundamental advantage for embedded control loops.
Key features include an internal 4 MHz RC oscillator (in -04 variants) for clock-free operation, an 8-level-deep hardware stack for sub-routine nesting, an interrupt controller capable of handling up to 7 internal/external interrupt sources, an 8-bit Timer0 with 8-bit prescaler, and a 16-bit Timer1. The integrated ADC and CCP module make the PIC16C716T-04/SO well-suited for closed-loop analog control applications such as sensor conditioning, motor control, and PWM-driven actuator stages.
Typical applications include appliance control boards, sensor interface front-ends, low-cost power-supply housekeeping blocks, automotive body controllers (non-safety), and industrial control modules. The combination of OTP memory (low unit cost in production volumes), an on-chip ADC, and CCP-driven PWM allows designers to consolidate analog sensing and digital actuation into a single 18-pin device.
When designing with this part, engineers should note that OTP memory is not re-programmable - firmware must be fully validated before commitment. The commercial temperature range (0C to +70C) and 5V supply requirement limit deployment in harsh environments; for industrial-grade, automotive-grade, or flash-reprogrammable equivalents, consult the PIC16F716 or PIC16C716-I variants respectively.

Ứng dụng tiêu biểu
PIC16C716T-04/SO phù hợp cho 6 Áp dụngs: Appliance Control Board, Sensor Interface Front-End, Low-Cost Power Supply Housekeeping, Automotive Body Controller (Non-Safety), Industrial Control Module, PWM-Driven LED Driver.
Appliance Control Board
The PIC16C716T-04/SO fits appliance control boards where its 4 MHz instruction cycle (200 ns) easily meets the timing demands of relay drivers, button debounce, and discrete sensor sampling. With 13 I/O pins the part can directly interface mechanical switches, LED indicators, triac-driven AC loads, and a few potentiometer inputs. The on-chip ADC reads temperature or pressure sensors, while the CCP module generates PWM for variable-speed motor control (fan, pump). OTP memory keeps unit cost low in high-volume white goods, and the 18-SOIC footprint supports automated SMT assembly lines. Power consumption at 5V and 4 MHz is well within the thermal budget for a sealed appliance enclosure. Use RC oscillator variants for cost-sensitive SKUs.

Sensor Interface Front-End
For sensor interface front-ends, the PIC16C716T-04/SO delivers an integrated ADC plus 13 digital I/O in a single 18-SOIC package, eliminating the need for a separate signal-conditioning IC. The PIC RISC core at 4 MHz comfortably runs linearization routines, moving-average filters, and serial output protocols to a host processor. With 3.5 KB OTP memory, calibration coefficients and lookup tables are co-resident with the main code. The CCP module generates accurate timing pulses for ultrasonic or capacitive distance sensors. The 5V supply and 0C to +70C commercial range suit indoor HVAC and building-automation sensor pods. For outdoor use, upgrade to PIC16F716-I/SO or PIC16C716-04I/SO with industrial temperature.

Low-Cost Power Supply Housekeeping
In switch-mode power supplies, the PIC16C716T-04/SO serves as a housekeeping MCU - monitoring auxiliary voltages via the on-chip ADC, controlling fan speed through the CCP/PWM module, sequencing power-good LEDs, and communicating fault status via GPIO. With 13 I/O pins the part can drive optocouplers, I2C EEPROMs, and front-panel indicators without external glue logic. The 4 MHz instruction cycle is more than adequate for slow housekeeping loops (1 ms or longer), and the 3.5 KB OTP memory stores state machines, fault logging, and PMBus-like command handling. Industrial-grade PIC16C716-04I/SO handles higher-temperature SMPS environments. Use the MCP1700 LDO for stable 5V rail.

Automotive Body Controller (Non-Safety)
Body-electronics modules such as window lift controllers, mirror adjusters, and interior lighting drivers can use the PIC16C716T-04/SO where AEC-Q100 is not required. The 13 I/O pins handle multiple switch inputs and H-bridge direction signals, while the ADC reads current-sense amplifiers for stall detection. The CCP module drives PWM for soft-start of DC motors. The commercial 0C to +70C range covers cabin environments but excludes under-hood deployment; for that, designers should specify the industrial PIC16C716-04I/SO or qualified AEC-Q100 PIC16F716 variants. The 18-SOIC package is well-supported by automotive EMS lines.

Industrial Control Module
Industrial control modules benefit from the PIC16C716T-04/SO's integrated ADC and CCP peripherals that close analog and PWM control loops in a single 18-SOIC device. The 4 MHz core runs PID controllers for valve actuators, conveyor speed regulators, and small-pump pressure regulators, while 128 bytes RAM hold a few process variables. The 3.5 KB OTP memory stores configuration constants and run-time state machines. Industrial-temperature deployments should select the PIC16C716-04I/SO (-40C to +85C) instead of the blank-speed-grade commercial part. The PIC RISC architecture offers deterministic interrupt response critical for control loops. The 18-SOIC package enables compact DIN-rail module form factors.

PWM-Driven LED Driver
The PIC16C716T-04/SO's CCP module generates precise PWM signals suitable for driving high-brightness LED strings via external MOSFETs. With 4 MHz clock and 200 ns instruction cycle, PWM frequencies above 1 kHz are achievable with 8-bit resolution, eliminating visible flicker in architectural and signage lighting. The 13 I/O pins support multiple LED channels, button inputs, and DMX-style receive logic. The on-chip ADC reads ambient light sensors for closed-loop brightness control, while 3.5 KB OTP memory holds color-mixing curves. Industrial temperature grade (PIC16C716-04I/SO) extends deployment to outdoor fixtures. Use logic-level MOSFETs to keep BOM cost low.

Ghi chú thiết kế
The PIC16C716 uses One-Time Programmable (OTP) EPROM - firmware bugs that are programmed into the device cannot be erased. Production firmware must be fully validated on PIC16F716 flash prototypes or on a windowed PIC16C716-JW emulation device before committing to OTP. Plan a PIC16F716 fall-back for any pilot run to allow last-minute code fixes without scrapping parts.
The PIC16C716T-04/SO is rated for a nominal 5V supply (per the PIC16C7xx family typical VDD range). Brown-out detection must be implemented in firmware by monitoring an ADC channel tied to VDD via a divider, because the older PIC16C716 silicon does not include the later BOR (Brown-Out Reset) module. Add a 100 nF decoupling capacitor close to the VDD pin and a 10 uF bulk capacitor at the regulator output to handle inrush from the ADC sample-and-hold.
When using the ADC, place the analog VDD and VSS traces away from the digital CCP1 PWM output pin (RC2) to avoid digital switching noise coupling into the analog inputs. A ground plane divided into analog and digital sections, joined at a single point under the MCU VSS pin, significantly improves ADC SNR. Reference the ADC from VDD (RA3 left as analog VREF+) when absolute accuracy is sufficient; for ratiometric measurements, drive VREF+ with the sensor bridge excitation voltage.
