Frequently Asked Questions
What is the minimum supply voltage at which PIC18F47K40-I/PT can operate, and why does this matter for battery designs?
The PIC18F47K40-I/PT can operate from as low as 2.3 V at 16 MHz, allowing it to run from a single alkaline or Li-primary battery through most of its discharge curve. This avoids the need for a boost converter in many portable designs, reducing BOM cost and power losses compared to MCUs requiring a 3.3 V or 5 V regulated supply.
How does the 64 MHz PIC18F47K40-I/PT compare in throughput to lower-cost 8-bit MCUs running at 20 MHz?
At 64 MHz, the PIC18F47K40-I/PT executes 8-bit PIC18 instructions at up to 16 MIPS (4 clock cycles per instruction), roughly 3 times the throughput of a 20 MHz MCU. This headroom allows more complex control algorithms, faster serial communication handlers, or higher-rate ADC sampling routines without moving to a costlier 16-bit or 32-bit device.
Is PIC18F47K40-I/PT compliant with REACH chemical regulations for new product designs?
Yes. The PIC18F47K40-I/PT carries a REACH compliance code of Compliant, confirming it does not contain substances of very high concern (SVHC) above the 0.1% threshold. This is required for export to EU markets and simplifies the compliance documentation process for OEMs building products subject to EU REACH regulations.
For a 44-pin TQFP layout, what I/O count and peripheral mix does PIC18F47K40-I/PT provide?
The PIC18F47K40-I/PT in the TQFP-44 package exposes dozens of GPIO pins shared with UART, SPI, I2C, and ADC inputs. The 44-pin TQFP body has a 0.8 mm pin pitch, fitting a standard SMT footprint that gives designers access to multiple communication ports and analog channels for sensor-rich applications without requiring a larger 64-pin package.
