Frequently Asked Questions
What is the maximum clock speed of PIC16F876-20/SO, and how much program and data memory does it provide?
The PIC16F876-20/SO operates at up to 20 MHz, executing one instruction per 4 clock cycles for an effective throughput of 5 MIPS. It includes 8 KB of Flash program memory, 368 bytes of SRAM data memory, and 256 bytes of data EEPROM for storing non-volatile configuration parameters or calibration values, providing a well-rounded memory set for mid-complexity 8-bit embedded applications.
How many analog input channels does PIC16F876-20/SO support, and what is the ADC resolution?
The PIC16F876-20/SO integrates a 5-channel 10-bit successive-approximation ADC, providing 1024 discrete levels across the analog input range. This allows direct connection to sensors such as thermistors, potentiometers, and pressure transducers with voltage outputs between 0 V and the supply voltage (typically 5 V or 3.3 V) without external ADC chips, simplifying the BOM in data acquisition and industrial monitoring designs.
Which serial communication interfaces are built into PIC16F876-20/SO, and what protocols do they support?
The PIC16F876-20/SO includes an MSSP (Master Synchronous Serial Port) supporting both SPI and I2C protocols, plus a USART module for asynchronous RS-232-style or synchronous serial communication. This combination enables the microcontroller to simultaneously manage I2C sensor buses at up to 400 kHz, SPI peripheral devices such as DACs and display drivers, and UART communication to a host PC or modem without any external logic.
For a PWM-based DC motor controller, which peripherals on PIC16F876-20/SO support pulse-width modulation?
The PIC16F876-20/SO has 2 CCP (Capture/Compare/PWM) modules, each capable of generating independent PWM signals with 10-bit duty-cycle resolution. At 20 MHz clock frequency, PWM carrier frequencies of several kilohertz to tens of kilohertz are achievable, suitable for controlling DC motors via H-bridge drivers, dimming LEDs, and driving servo motors. Both CCP channels can operate simultaneously for dual-channel motor or actuator control.
Is PIC16F876-20/SO still available for new designs, and what packaging format does it come in for production assembly?
The PIC16F876-20/SO is housed in a 28-pin SOIC (Small Outline IC) package compatible with standard SMT pick-and-place and reflow soldering processes. While introduced in 1998 and noted with a limited years-to-end-of-life window, it remains available through authorized distributors with typical factory lead times around 29 weeks. For new designs requiring longer-term supply assurance, Microchip recommends evaluating newer PIC16F or PIC18 series devices with enhanced peripherals and broader availability.
