PIC16F73-I/SS - 8-Bit 20MHz Microcontroller | Microchip Technology
MPN: PIC16F73-I/SS ✗ Akhir HidupPIC16F73-I/SS Ringkasan
A PIC microcontroller is a programmable controller integrated with CPU, memory, timers, serial interfaces, and I/O in one semiconductor package. Within the product hierarchy, the PIC16F73 belongs to the PIC16 family of 8-bit RISC microcontrollers and combines a compact instruction set with dedicated hardware peripherals. This makes the device a general-purpose embedded-control platform rather than a simple fixed-function logic component.
Verified features include five 8-bit analog-to-digital converter channels, two additional timers, two capture/compare/PWM functions, and a synchronous serial port configurable for three-wire SPI or two-wire I²C. The same synchronous serial port can support the USART according to the manufacturer product page. These peripherals reduce external hardware requirements for sensing, timing, motor or PWM control, and communications.
The PIC16F73 is based on Microchip’s PIC architecture and supports execution described in verified source material as 200 ns per instruction, with only 35 single-word instructions. Its CMOS FLASH-based design permits in-system programming and reusable firmware development, while the 8-bit CPU is suited to embedded control, instrumentation, simple data acquisition, and communication-enabled products.
Typical applications include industrial sensor controllers, compact data-acquisition systems, serial bridges, timing modules, and low-cost embedded control boards. The 22 I/O pins provide substantial external connectivity for sensors, displays, relays, actuators, and logic interfaces. Designers should verify the exact package pinout, power limits, timing values, and peripheral configuration from the manufacturer datasheet before final PCB release.
A key design consideration is pin planning: the 28-pin SSOP footprint must be mapped carefully against the selected oscillator, programming interface, analog inputs, serial pins, and I/O direction requirements. Because the supplied data does not provide a complete verified electrical table, unverified values are marked for engineering follow-up rather than inferred from the MCU family.
This product page combines verified distributor and manufacturer information with an explicit distinction between documented facts and missing engineering data. That approach supports faster sourcing and design review while avoiding unsupported assumptions about memory, timing, compliance, or replacement behavior.

Aplikasi Umum
PIC16F73-I/SS cocok untuk 6 aplikasis: Industrial Sensor Controller, Serial Data Acquisition Module, Motor and PWM Control, Instrumentation and Measurement, Communication Bridge, Embedded Consumer Accessory.
Industrial Sensor Controller
PIC16F73-I/SS fits an industrial sensor controller that needs 22 I/O pins, five 8-bit ADC channels, and embedded timing in a compact 28-pin SSOP. Its verified 20 MHz maximum clock and FLASH-based architecture support firmware that reads sensors, applies control logic, and drives relays or indicators without requiring a separate microcontroller family. The two additional timers and two capture/compare/PWM functions can organize periodic sampling, input timing, and actuator control. Because the supplied data does not specify the exact supply range, industrial temperature limits, or EMC performance, the final design must verify those parameters from the manufacturer datasheet and validate the completed equipment for its target environment.

Serial Data Acquisition Module
PIC16F73-I/SS is suitable for a compact serial data-acquisition module because the manufacturer identifies five 8-bit ADC channels plus a synchronous serial port configurable as SPI or I²C, along with USART support. The 7 KB FLASH and 192 bytes of RAM provide resources for acquisition sequencing and protocol handling, while 22 I/O pins leave room for sensors, status indicators, and configuration controls. The 28-pin SSOP package helps reduce board area, although careful pin budgeting is required for analog inputs, programming, oscillator components, and serial signals. Firmware should account for conversion sequencing, input scaling, bus timing, and calibration before production deployment.

Motor and PWM Control
PIC16F73-I/SS can serve as the control MCU in a small motor, valve, or PWM-driven actuator module. Its two capture/compare/PWM functions provide hardware resources for generating or measuring timed waveforms, while the 20 MHz maximum clock and 8-bit architecture support deterministic control logic. The 22 I/O pins can connect position inputs, limit sensors, logic-level enable signals, and status outputs. The verified data does not include absolute maximum ratings or PWM timing parameters, so the selected switching devices, gate drivers, protection components, and current limits must be designed separately and verified against the full datasheet and application requirements.

Instrumentation and Measurement
PIC16F73-I/SS is a reasonable fit for compact instrumentation that combines analog sensing with serial reporting. Five 8-bit ADC channels provide a basic measurement front end, while SPI, I²C, and USART options allow the controller to communicate with displays, sensors, computers, or service interfaces. The 7 KB FLASH capacity is appropriate for moderate control and calibration firmware, and the 192-byte RAM can support buffered working data, although the final memory budget must be calculated with the selected compiler. Engineers should verify ADC accuracy references, acquisition timing, input impedance requirements, and grounding before treating the MCU as a precision measurement instrument.

Communication Bridge
PIC16F73-I/SS can act as a communication bridge between a local sensor or control subsystem and an external host. The synchronous serial port supports three-wire SPI or two-wire I²C, and the manufacturer also identifies USART capability, allowing the same controller to participate in multiple embedded communication schemes. The 28-pin SSOP package supports compact boards, while 22 I/O pins can handle interface mode, status, fault, and user-control signals. Firmware must manage protocol timing, buffering, timeout behavior, and pin multiplexing carefully. The verified data does not specify maximum bus rates or electrical interface thresholds, so those values must be taken from the full manufacturer documentation.

Embedded Consumer Accessory
PIC16F73-I/SS can support a compact embedded accessory that combines local control, status LEDs, a keypad, and serial configuration. Its FLASH-based 8-bit architecture is straightforward for embedded firmware, and the 22 I/O pins provide flexibility for human-interface and control signals. The five ADC channels can be used for battery or analog status monitoring, while timer and PWM resources support indicators or small actuators. The industrial-grade ordering option may be useful when product requirements call for a broader temperature class, but the supplied data does not state exact temperature limits or package endurance. Validate electrical behavior, programming workflow, and enclosure-related thermal conditions before release.

Catatan Desain
Reserve the 28-pin SSOP footprint and route all power, programming, oscillator, ground, and peripheral signals from the official package drawing. Keep the MCU ground path short and provide a local decoupling arrangement using the capacitor values and placement guidance in the manufacturer datasheet. Because the supplied data does not include the complete pin table, do not finalize the schematic by assigning functions solely from the 22-I/O count.
Verify VDD and VSS limits, operating current, brownout behavior, and I/O input thresholds from the complete PIC16F73 datasheet before selecting regulators or external interface devices. The 20 MHz maximum clock is confirmed, but supply requirements are not included in the supplied excerpts. Ensure the power source has adequate transient margin and that any interface connected to the MCU remains within the verified electrical limits.
Plan the PCB for clean analog and digital signal separation. The five ADC channels may be sensitive to source impedance, sampling charge, grounding, and digital switching noise; follow the datasheet acquisition and external-component recommendations. For SPI, I²C, or USART lines, use the manufacturer-specified pull-up, termination, and routing practices where applicable, and keep clock or serial traces away from high-current switching nodes.
Informasi Konformitas
Compliance information is not included in the supplied verified excerpts. Do not infer RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-mineral status from the package or distributor listings.
