Frequently Asked Questions
How low can the PIC18LF46K22-I/ML supply voltage go while still running at 20 MHz?
The PIC18LF46K22 can operate from a supply voltage as low as 1.8 V while running at up to 20 MHz, making it directly compatible with single-cell lithium batteries and energy-harvesting power sources. At higher voltages up to 3.6 V, the device can reach its maximum clock frequency of 64 MHz for more demanding tasks.
What on-chip memory does the PIC18LF46K22-I/ML provide for embedded firmware and data storage?
The PIC18LF46K22 integrates 64 KB of Flash program memory and 3968 bytes of SRAM, providing sufficient storage for moderately complex firmware in industrial or consumer embedded applications. It also includes 1024 bytes of EEPROM data memory, enabling non-volatile parameter storage without requiring an external EEPROM device.
Which compact embedded designs benefit most from the 44-pin QFN package of the PIC18LF46K22?
The 44-pin QFN package measures approximately 8 mm × 8 mm, offering a much smaller footprint than a 44-pin TQFP at the same pin count. This makes the PIC18LF46K22-I/ML ideal for small handheld devices, wearable sensors, and PCB-constrained IoT modules where board real estate is limited but a high I/O count of up to 36 GPIO pins is still needed.
Is the PIC18LF46K22-I/ML a suitable drop-in alternative to the PIC18F46K22 for 3.3 V systems?
The PIC18LF46K22 (low-voltage variant) supports 1.8 V to 3.6 V operation, while the standard PIC18F46K22 runs from 2.0 V to 5.5 V. For 3.3 V systems both devices are pin-compatible and firmware-compatible, but the LF variant is preferred when power optimization at 3.3 V is a priority, as it draws less supply current during active and sleep modes at equivalent clock frequencies up to 64 MHz.
