PIC16C716-04I/SS - 8-Bit 4MHz MCU, 3.5KB OTP, 20-SSOP | Microchip
MPN: PIC16C716-04I/SS ✓ Hoạt độngPIC16C716-04I/SS Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (program + data), and programmable I/O peripherals on one die, allowing engineers to implement embedded control logic with a minimum of external components. The PIC16C716 belongs to the broader category of 8-bit microcontrollers (8-bit -> MCU -> embedded controller -> semiconductor), using Microchip's RISC instruction set with 35 single-word instructions. This architecture is widely used in automotive, industrial, appliance, and consumer applications where deterministic real-time control, low power, and compact code density are required.
Key features of the PIC16C716-04I/SS include an operating speed of DC to 4 MHz (the "-04" speed grade), up to 7 internal/external interrupt sources, an 8-level hardware stack, and a 4-channel 8-bit ADC that enables direct interface with analog sensors without external ADC ICs. The two additional timers and CCP module provide flexible PWM generation and input-capture functions for motor control, signal measurement, and timing applications.
The PIC16C716 architecture is based on a Harvard-bus RISC core, separating program memory (14-bit wide OTP) from data memory (8-bit wide SRAM) to enable single-cycle instruction execution except for program branches (2 cycles). This pipelined design, combined with the 200 ns instruction cycle at 4 MHz, gives the MCU deterministic throughput well suited to real-time control loops. The industrial temperature grade ("-I") supports an operating range of -40°C to +85°C.
Typical applications include sensor signal conditioning, low-cost motor control (small DC fans, solenoids), automotive body controllers, appliance control boards, and battery-powered instruments requiring OTP programmability for cost-effective mid-volume production runs. The 20-SSOP footprint also makes it attractive for compact consumer designs.
When designing with this device, note that OTP memory is one-time programmable and cannot be re-flashed; for field-updatable firmware, consider the flash-based PIC16F716 (same 20-SSOP pinout). Always use Microchip's MPLAB X IDE with a compatible programmer (e.g., PICkit 3/4, ICD) for code development.

Ứng dụng tiêu biểu
PIC16C716-04I/SS phù hợp cho 6 Áp dụngs: Automotive Body Controllers, Sensor Interface Modules, Small Motor / Fan Speed Control, Consumer Appliance Control, Battery-Powered Instrumentation, Industrial Timer / Sequencer.
Automotive Body Controllers
The PIC16C716-04I/SS fits automotive body and lighting control modules thanks to its 4-channel 8-bit ADC for analog sensor input, 13 GPIO pins for switches and relay drivers, and CCP module for PWM dimming. Its 4 MHz CPU with 200 ns instruction cycle delivers deterministic real-time response for body-electronics tasks like seat control, mirror adjustment, and ambient lighting, while the industrial temperature grade (-40°C to +85°C) handles under-dash thermal environments. The 3.5 KB OTP memory holds compact application firmware for these price-sensitive modules, and the small 20-SSOP footprint (5.30 mm body) enables placement in tight housing.

Sensor Interface Modules
The PIC16C716-04I/SS's integrated 4-channel 8-bit ADC and 13 GPIO make it ideal for low-cost sensor interface modules reading temperature, light, humidity, or potentiometer signals. The 4 MHz core and 200 ns instruction cycle deliver 5 MIPS, sufficient for sampling four analog channels at hundreds of Hz, computing averages, and transmitting over UART or I/O. The 128-byte RAM is adequate for small data buffers, and the OTP memory prevents accidental firmware erasure in field-deployed industrial sensors. Power consumption is low, supporting battery-powered remote sensor nodes.
Được đề xuất
Small Motor / Fan Speed Control
The PIC16C716-04I/SS is well suited for small DC motor or fan speed control using its on-chip CCP module for PWM generation and 4-channel ADC for closed-loop tachometer feedback. The 200 ns instruction cycle at 4 MHz allows precise PWM duty-cycle updates (8-bit resolution at standard PWM frequency), while the 13 GPIO pins accommodate direction-control relays, fault inputs, and status LEDs. The industrial temperature range supports appliance and industrial environments, and the compact 20-SSOP package fits inside small motor housings or fan assemblies.
Được đề xuất
Consumer Appliance Control
The PIC16C716-04I/SS provides the right mix of integration and cost for white-goods and small-appliance controllers (coffee makers, toasters, washing-machine sub-modules, microwave keypads). The 4-channel ADC reads temperature, water level, or humidity sensors directly; the CCP module drives buzzers, triacs, or relays; and 13 GPIO scan keypads and LED indicators. OTP memory at 3.5 KB accommodates typical appliance state machines, and the 20-SSOP surface-mount package suits automated PCB assembly lines in high-volume consumer production.
Được đề xuất
Battery-Powered Instrumentation
Low-power battery-powered instruments benefit from the PIC16C716-04I/SS's sleep/idle modes, wide 2.5 V to 5.5 V operating range, and on-chip ADC for direct sensor digitization without external ICs. The 4 MHz CPU and 128 B RAM are sufficient for data logging, slow-rate sampling, and UART/binary output to a host, while the industrial temperature range supports field-deployed measurement tools. OTP memory locks firmware at production time, protecting proprietary calibration constants. The 20-SSOP footprint allows compact handheld enclosures.
Được đề xuất
Industrial Timer / Sequencer
The PIC16C716-04I/SS functions as a flexible industrial timer or sequencer, leveraging its two additional timers (beyond the WDT), CCP module, and 13 GPIO to drive relays, solenoids, and indicator LEDs in deterministic time-based sequences. The 4 MHz CPU with hardware stack and 7 interrupt sources handles multi-stage timing with minimal jitter, and the industrial temperature grade operates reliably in factory environments. The 20-SSOP package and OTP memory provide cost-effective deployment for fixed-function industrial controllers.

Bảo phân biệt quan trọng
- Integrated 4-channel 8-bit ADC eliminates external ADC chip (vsPIC16C715-I/SS)
- Industrial temperature grade -40°C to +85°C (vsPIC16C716-04/SS)
- Same-family PIC16 architecture enables firmware reuse across PIC16C/PIC16F (vsNon-PIC alternatives (e.g., ATmega, MSP430))
Ghi chú thiết kế
The PIC16C716-04I/SS operates from 2.5 V to 5.5 V on VDD (pin 20) with VSS (pin 19) as ground. Decouple VDD with a 100 nF ceramic capacitor placed within 5 mm of the supply pin and a bulk 10 µF tantalum or aluminum electrolytic capacitor at the board entry point. The MCU draws roughly 2-5 mA active at 4 MHz/5 V and can drop below 1 µA in sleep mode, so a low-Iq LDO such as MCP1700 is recommended for battery-powered designs.
OTP (One-Time Programmable) memory cannot be erased or rewritten - once a bit cell is programmed, the firmware is permanent. This means prototype debugging must use the PIC16F716-I/SS (flash-based, same 20-SSOP pinout) or a windowed/UV-erasable PIC16C716 JW variant. Plan firmware revisions and last-minute bug fixes carefully before committing to OTP, and always run final code on PIC16F716-I/SS for sign-off before switching to the OTP PIC16C716-04I/SS for production.
For the 20-SSOP (5.30 mm body, 0.65 mm pitch) footprint, follow IPC-7351 land-pattern guidelines: pad length 0.95 mm, pad width 0.40 mm, with 0.30 mm solder mask expansion. The exposed die-pad underneath is not present on this SSOP variant, so thermal dissipation is through the 20 leads only - keep continuous ground plane on the top layer connected to VSS pin 19 to spread heat. Place the decoupling capacitor on VDD within 5 mm and route the analog AVdd/AVss traces away from switching signals to avoid ADC noise pickup.
