Frequently Asked Questions
What is the maximum clock speed and supply voltage range of the PIC18LF452-I/L?
The PIC18LF452-I/L operates at up to 40 MHz clock frequency and supports supply voltages from 2.0 V to 5.5 V. At reduced frequency of 4 MHz, it can operate from as low as 2.0 V, making it suitable for battery-powered and low-power embedded control applications.
How much flash memory and RAM does the PIC18LF452-I/L provide for firmware storage?
The PIC18LF452-I/L includes 32 KB of flash program memory and 1.5 KB of SRAM data memory. This capacity supports moderately complex firmware for industrial sensors, motor control, and communication-intensive embedded applications without requiring external memory.
What communication interfaces are integrated in the PIC18LF452-I/L?
The PIC18LF452-I/L integrates USART, SPI, and I2C serial communication interfaces, enabling connection to a wide range of sensors, displays, and other peripherals. These built-in modules reduce external component count and simplify PCB design in embedded control systems.
For which types of embedded control designs is the PIC18LF452-I/L a strong fit?
The PIC18LF452-I/L is a strong fit for industrial control panels, home automation nodes, and portable data loggers that benefit from 8-bit processing at up to 40 MHz with on-chip 10-bit ADC sampling across 8 input channels. Its low-voltage operation to 2.0 V suits battery-powered sensor nodes.
What package does the PIC18LF452-I/L use and how does it differ from DIP alternatives?
The PIC18LF452-I/L uses a 44-pin PLCC (Plastic Leaded Chip Carrier) package, which offers a square footprint suitable for socket-based or soldered PCB assembly. Compared to DIP alternatives, the PLCC-44 provides denser pin routing and higher I/O count in a smaller board area.
