Frequently Asked Questions
What are the memory and I/O specifications of the PIC16LF873-04/SO?
The PIC16LF873-04/SO features 7KB of Flash program memory, 192 bytes of data RAM, and 22 general-purpose I/O pins. These resources support moderate-complexity embedded firmware with real-time I/O control, making it suitable for sensor interfacing, display driving, and simple communication tasks.
What is the maximum clock frequency of the PIC16LF873-04/SO?
The PIC16LF873-04/SO operates at a maximum clock frequency of 4MHz, which corresponds to 1 MIPS instruction throughput on the PIC architecture. The '-04' suffix in the part number specifically designates this 4MHz speed grade, distinguishing it from higher-frequency variants of the PIC16LF873 family.
What communication peripherals does the PIC16LF873-04/SO include?
The PIC16LF873-04/SO includes a USART (Universal Synchronous/Asynchronous Receiver Transmitter), SPI (Serial Peripheral Interface), and I2C (Inter-Integrated Circuit) modules, along with an integrated 10-bit ADC. This peripheral set allows direct connection to a wide range of sensors, serial memory devices, displays, and other digital systems.
What package does the PIC16LF873-04/SO use?
The PIC16LF873-04/SO is housed in a 28-pin SOIC (Small Outline Integrated Circuit) package with standard 1.27mm pitch, as indicated by the '/SO' package suffix. This surface-mount package is widely supported by PCB manufacturing and assembly processes, and its pin count provides access to all 22 I/O pins plus power and ground.
Is the PIC16LF873-04/SO still in production and is it RoHS compliant?
The PIC16LF873-04/SO was introduced in December 1998 and has a YTEOL (years to end of life) indicator of 3, suggesting it is approaching end-of-life status. It is fully RoHS compliant and lead-free. Designers starting new projects may wish to evaluate newer PIC16 or PIC18 devices, but it remains available for legacy system support and maintenance purposes.
