PIC16C716-04I/P - 8-Bit 4MHz OTP MCU 18-PDIP | Microchip
MPN: PIC16C716-04I/P ✓ Hoạt độngPIC16C716-04I/P Tóm tắt
An 8-bit microcontroller (MCU) is a small computer-on-a-class IC containing a CPU, RAM, non-volatile program memory, and peripherals. The PIC16C716 belongs to the mid-range PIC16 family, sitting hierarchically under: microcontroller -> embedded MCU -> semiconductor. It uses One-Time Programmable (OTP) EPROM rather than Flash, meaning the program memory can be written only once — a fit for cost-sensitive production runs where code is finalized before manufacturing.
Key features include a high-performance RISC CPU executing instructions in 200 ns at 20 MHz (5 MHz input), 35 single-word instructions, 4 channels of 8-bit A/D converter, a Capture/Compare/PWM (CCP) module, 2 timers (Timer0 with 8-bit prescaler, Timer2), Brown-out Reset (BOR), and 13 I/O pins with individual direction control. The '04' speed grade denotes 4 MHz and the 'I' suffix indicates the industrial temperature range.
The device operates from 4.0 V to 5.5 V and supports in-circuit serial programming (ICSP) via the RB6/RB7 pins. The 18-pin PDIP footprint and PIC mid-range instruction set provide straightforward migration to flash-based siblings such as the PIC16F716 family.
Typical applications include consumer appliance control, sensor signal conditioning, low-cost motor control via CCP/PWM, battery chargers, and industrial automation where OTP cost advantages outweigh re-programmability needs. The industrial temperature grade supports -40C to +85C operating environments.
When designing with the PIC16C716-04I/P, reserve the RB6/RB7 pins for ICSP programming, include a 100 nF decoupling capacitor adjacent to VDD, and place a bulk capacitor near the analog AVSS/AVDD pair to minimize ADC noise. Because the OTP variant cannot be reprogrammed, choose the PIC16F716-I/P if field re-programmability is required.

Ứng dụng tiêu biểu
PIC16C716-04I/P phù hợp cho 6 Áp dụngs: Consumer Appliance Control, Battery Charger Controller, Sensor Signal Conditioning, Low-Cost PWM Motor Control, Industrial Automation Module, Hobby / Educational Embedded Platform.
Consumer Appliance Control
The PIC16C716-04I/P fits consumer appliance control boards thanks to its 4-channel 8-bit ADC for sensor reading (temperature, humidity, level), 13 digital I/O for keypad/relay/LED driving, and CCP/PWM for triac-based heater or motor speed control. The OTP memory cost advantage versus Flash makes it attractive for high-volume washers, rice cookers, and microwave ovens where firmware is finalized. At 4 MHz it executes one instruction per microsecond, ample for polled sensor loops under 10 ms. Industrial -40C to +85C temperature grade tolerates kitchen and laundry environments. The 18-pin PDIP through-hole package supports wave soldering on cost-sensitive appliance PCAs.

Battery Charger Controller
The PIC16C716-04I/P serves as the supervisory MCU in linear or switch-mode battery chargers, using its ADC to monitor charge current (across a sense resistor) and battery voltage, while the CCP/PWM module drives a MOSFET or secondary-side controller. The Brown-out Reset prevents erroneous charging at low VDD. OTP memory removes field-reprogramming concerns in sealed charger modules. 4 MHz operation provides 1 us instruction timing, more than enough for PI compensation loops in CC/CV algorithms. Industrial temperature grade supports garage, outdoor, and automotive-cabin charger applications.

Sensor Signal Conditioning
Bridge sensors, thermistors, and ratiometric transducers connect directly to the PIC16C716-04I/P's 4-channel 8-bit ADC, with the MCU performing offset/gain correction in firmware. The 128-byte RAM accommodates 4-channel lookup tables and running averages. The 13 digital I/O drive LCD segments, status LEDs, or communication transceivers. Industrial temperature grade and OTP cost make it a strong fit for sealed transducers shipped in high volume (pressure, flow, gas). The Capture input on the CCP module measures pulse-width outputs from flow meters or ultrasonic transducers.

Low-Cost PWM Motor Control
Small DC brushed motors and fans operate from the PIC16C716-04I/P's CCP/PWM output at frequencies up to ~10 kHz with 10-bit resolution (using Timer2 postscaler). The MCU's 13 I/O handle direction control, tach feedback, and fault inputs. Industrial temperature grade tolerates motor-housing environments. At 4 MHz the MCU's 1 us timing accuracy is sufficient for PID velocity loops in fan or pump applications. OTP memory ensures production firmware cannot be field-tampered. The 18-pin PDIP package simplifies hand-rework and field-service replacement on hobby and appliance motor boards.

Industrial Automation Module
Distributed I/O modules and small PLCs use the PIC16C716-04I/P as a slave controller: the ADC reads 4 analog field signals (4-20 mA via shunt, or 0-10 V via divider), and the digital I/O drive optocouplers to switch 24 V loads. OTP memory prevents unauthorized firmware replacement in factory-floor installations. Industrial temperature grade and BOR ensure reliable behavior in electrically noisy cabinets. The 18-pin PDIP allows easy socket-mounting for service swap. With 4 MHz operation, the MCU services 4-channel ADC at >1 kS/s aggregate, more than enough for process-control loops at 10-100 Hz.

Hobby / Educational Embedded Platform
Hobbyists and students use the PIC16C716-04I/P as an introductory 8-bit platform because the 18-pin PDIP is breadboard-friendly, ICSP works with a $5 PICKit programmer, and the 35-instruction mid-range core is well-documented in Microchip application notes. The CCP/PWM, ADC, and timers provide a complete peripheral set for robotics, LED cubes, and IR remote projects. OTP memory is a teaching moment about production firmware strategy. The 4 MHz '04' speed grade bin is plenty for hand-rolled assembly code at microsecond resolution.

Ghi chú thiết kế
Place a 100 nF ceramic decoupling capacitor as close as possible between VDD (pin 14 in PDIP-18 layout, or per specific datasheet pin) and VSS. For ADC applications, add a separate 10 uF + 100 nF bulk/decoupling pair on AVSS/AVDD to minimize digital switching noise coupling into analog readings. Keep the crystal or resonator traces between OSC1 and OSC2 short (<10 mm) and shield them with a ground pour to reduce EMI susceptibility.
RB6 and RB7 are shared between general digital I/O and the ICSP programming interface. If your firmware re-purposes these pins as outputs at firmware initialization time before programming is complete, the device may appear bricked. Add a 10 kohm pull-up to RB7 (PGD) so the ICSP programmer can override the pin state during programming. Also confirm MCLR is tied through a resistor to VDD (typically 10 kohm) so the device can start in normal operation.
The PIC16C716-04I/P ADC achieves its 8-bit resolution only when source impedance is below 10 kohm (per the Microchip datasheet acquisition time specification). When reading high-impedance sensors (e.g., bare thermistors > 100 kohm at low temperature), buffer the signal with an op-amp or add a hold capacitor to keep acquisition-time error below 1/2 LSB. Switching the ADC channel mid-acquisition requires a 2.4 us minimum acquisition delay.
Brown-out Reset (BOR) on the PIC16C716-04I/P holds the MCU in reset when VDD falls below approximately 4.0 V, preventing code execution from corrupted program memory. For battery-powered designs where VDD may droop below BOR, plan for either external POR or migrate to PIC16LF182x which provides programmable BOR thresholds. Estimated: BOR current draw is < 1 mA based on mid-range PIC typical characteristics.
