Frequently Asked Questions
What CPU core and maximum frequency does PIC32MX340F256H-80I/PT provide for demanding embedded firmware?
The PIC32MX340F256H-80I/PT uses a 32-bit MIPS32 M4K core clocked at up to 80 MHz, delivering significantly more throughput than 8-bit or 16-bit PIC devices. It pairs this with 256 KB Flash and 32 KB SRAM, supporting complex RTOS-based or bare-metal firmware for motor control, communications, and HMI applications.
Does PIC32MX340F256H-80I/PT support USB connectivity, and what USB roles can it serve in a design?
Yes. The PIC32MX340F256H-80I/PT integrates a USB 2.0 Full-Speed controller supporting device, host, and OTG (On-The-Go) modes, operating at 12 Mbps. This allows the MCU to act as a USB peripheral (e.g., HID, CDC, mass storage), a USB host driving flash drives, or a dual-role OTG port depending on the application.
What ADC resolution and channel count does PIC32MX340F256H-80I/PT offer for industrial analog signal acquisition?
The PIC32MX340F256H-80I/PT features a 10-bit SAR ADC with multiple input channels, suitable for reading temperature sensors, pressure transducers, current shunts, and other 0-5 V analog signals in industrial environments. The 10-bit resolution provides 1024 discrete levels, yielding approximately 5 mV resolution on a 5 V reference.
What is the lead time for PIC32MX340F256H-80I/PT, and is the device still active for new design wins?
The PIC32MX340F256H-80I/PT has a factory lead time of approximately 8 weeks and carries a YTEOL rating of 8, indicating ongoing active production. Engineers starting new designs can consider this part as a current lifecycle product, though verifying stock levels with distributors is recommended before committing to a production BOM.
