Frequently Asked Questions
What is the minimum supply voltage for the PIC18LF2523-I/SO and at what clock frequency can it operate under that condition?
The PIC18LF2523-I/SO operates from a minimum supply voltage of 2 V, but at that voltage the maximum clock frequency is limited to 4 MHz. This low-voltage capability makes it suitable for battery-powered applications powered by two AA cells or energy harvesting systems, while still providing sufficient processing speed for sensor reading and communication tasks.
How many ADC channels does the PIC18LF2523-I/SO offer and what resolution does each channel provide?
The PIC18LF2523-I/SO includes 10 analog input channels connected to a 12-bit ADC, providing 4096 quantization levels per channel. This multi-channel 12-bit capability enables simultaneous reading of multiple sensors such as temperature, humidity, and pressure transducers in a single IC without requiring external ADC expansion chips.
For a compact embedded controller design, what flash and RAM does the PIC18LF2523-I/SO provide?
The PIC18LF2523-I/SO offers 32 KB of flash program memory and 1536 bytes of RAM, giving firmware developers sufficient space for mid-complexity embedded control algorithms, communication stacks, and data buffers within the 8-bit PIC18 architecture operating at up to 40 MHz.
Which package does the PIC18LF2523-I/SO come in and how does this affect its I/O pin availability?
The PIC18LF2523-I/SO is packaged in a 28-pin SOIC (Small Outline IC) with 1.27 mm pin pitch, providing 25 general-purpose I/O pins across ports A, B, and C. The SOIC-28 package offers a balance between I/O count and compact PCB footprint of approximately 17.9 mm x 7.5 mm, making it suitable for mid-complexity embedded designs requiring multiple peripherals including USART, SPI, I2C, and 10 analog inputs.
