Key Features
- 8-bit PIC16 core running at up to 20 MHz with 7KB Flash program memory and 128B EEPROM for non-volatile data storage
- 5-channel 10-bit ADC plus two Capture/Compare/PWM (CCP) modules enabling versatile analog and timing control
- Compact QFN-28 (VQFN-28) package with industrial-range operation from 4 V minimum supply voltage
Applications
The PIC16F873A-I/ML suits embedded control applications such as motor-drive sequencers, industrial sensor nodes, and home-automation controllers where a compact 28-pin footprint is critical. Its dual CCP modules and 5-channel ADC make it well-suited for PWM-driven actuator boards operating from 4 V to 5.5 V rails. The on-chip EEPROM retains calibration data across power cycles, benefiting metering and data-logging designs.

Frequently Asked Questions
What is the maximum clock frequency and how much Flash memory does the PIC16F873A-I/ML provide?
The PIC16F873A-I/ML runs at up to 20 MHz and provides 7 KB of Flash program memory along with 128 bytes of EEPROM and 192 bytes of RAM, making it suitable for moderately complex embedded firmware in a 28-pin QFN package.
Which analog front-end capabilities does the PIC16F873A-I/ML offer for sensor-interface designs?
It includes a 5-channel 10-bit ADC capable of sampling analog inputs with up to 1024 discrete steps, plus a synchronous serial port (SSP) supporting SPI and I2C at up to 400 kHz, enabling direct interfacing with pressure sensors, temperature ICs, and other analog peripherals.
When would a designer choose the PIC16F873A-I/ML over the larger PIC16F876A?
The PIC16F873A-I/ML is preferable when the application fits within 7 KB Flash and 192 bytes RAM and PCB space is constrained, as the QFN-28 package occupies significantly less board area than the 28-pin SPDIP of the PIC16F876A while sharing the same 20 MHz core and 10-bit ADC channels.
What supply voltage range and temperature grade apply to the PIC16F873A-I/ML?
The PIC16F873A-I/ML operates from a 4 V minimum to 5.5 V maximum supply voltage and is rated for the industrial temperature range of -40 °C to +85 °C, making it appropriate for control boards in harsh factory or outdoor environments.
