Frequently Asked Questions
What makes PIC18F46J11-I/PT XLP technology advantageous for a coin-cell powered temperature sensor transmitting every 60 seconds?
PIC18F46J11-I/PT's eXtreme Low Power (XLP) sleep mode draws as little as 20 nA at 1.8 V, versus 1–2 µA for standard PIC18 devices. For a sensor waking every 60 seconds for a 10 ms active period at 1 mA, the average current drops to approximately 200 nA, extending a 230 mAh CR2032 coin cell to over 10 years of operation compared to roughly 3 years for a non-XLP device.
How fast can PIC18F46J11-I/PT run and is 48 MHz sufficient for a USB Full Speed implementation?
PIC18F46J11-I/PT operates up to 48 MHz, which is the exact clock frequency required for USB Full Speed operation at 12 Mbps using Microchip's USB library. The 48 MHz clock can be derived from an internal oscillator with a PLL, eliminating the need for an external crystal in USB device designs and reducing BOM cost while meeting the ±0.25% frequency accuracy requirement for USB enumeration.
For a 3.3 V wireless sensor hub needing 8 ADC channels, does the 44-pin TQFP of PIC18F46J11-I/PT provide enough I/O alongside SPI and I2C buses?
The 44-pin TQFP package of PIC18F46J11-I/PT exposes up to 36 usable digital I/O pins and 12 ADC-capable pins. Allocating 4 pins for SPI (SCK, SDI, SDO, CS), 2 pins for I2C (SDA, SCL), and 8 ADC inputs consumes 14 pins, leaving 22 free for LEDs, buttons, PWM outputs, and UART. This is adequate for a typical wireless sensor hub without requiring an external I/O expander.
When should a designer choose PIC18F46J11-I/PT over the larger PIC18F65J11T-I/PT for an industrial panel meter?
PIC18F46J11-I/PT in TQFP-44 is the better choice when the design fits within 36 digital I/Os and 12 ADC channels, as it reduces PCB area by roughly 40% compared to the 64-pin TQFP-64 of PIC18F65J11T. Additionally, PIC18F46J11 adds XLP low-power capability absent in PIC18F65J11T, benefiting panel meters that enter sleep mode between readings. Choose PIC18F65J11T only when more than 36 I/Os or 12 ADC channels are required.
