Frequently Asked Questions
What program and data memory does PIC16LF84-04I/SO provide for embedded firmware storage?
PIC16LF84-04I/SO offers 1.75 KB Flash program memory for firmware storage and 64 bytes of EEPROM for non-volatile data retention such as calibration coefficients or configuration settings, along with 68 bytes of SRAM for runtime variables in 8-bit control applications.
How does the 2.0 V to 5.5 V supply range of PIC16LF84-04I/SO benefit battery-powered designs?
The wide supply range of 2.0 V to 5.5 V allows the PIC16LF84-04I/SO to operate directly from two alkaline AA cells at 3 V nominal without a voltage regulator, reducing BOM cost. Its sleep mode current below 1 µA extends battery life in always-on applications such as remote controls and wireless sensor nodes.
Which legacy control applications are still maintained using PIC16LF84-04I/SO in production?
Industrial timers, relay sequencers, and simple keypad-based control panels originally designed with PIC16LF84 continue to use this device in production due to its long availability history and stable pinout. The 18-pin SOIC package is compatible with existing PCB footprints, avoiding costly board redesigns for low-volume industrial control equipment.
What is the maximum clock frequency of PIC16LF84-04I/SO and how does it affect instruction throughput?
PIC16LF84-04I/SO operates at a maximum clock frequency of 4 MHz, achieving 1 MIPS throughput since each instruction executes in 4 clock cycles. This throughput is sufficient for simple I/O control, switch debouncing, and serial communication tasks at baud rates up to 9600 bps in embedded control applications.
