Frequently Asked Questions
What is the maximum clock frequency of PIC32MX440F256H-80I/MR and how much flash does it integrate?
PIC32MX440F256H-80I/MR operates at a maximum CPU frequency of 80 MHz with 256 KB of on-chip flash memory. This combination supports real-time embedded firmware for USB data logging, motor control, and HMI applications without requiring external program memory, reducing BOM cost and PCB complexity.
How does the USB OTG feature of PIC32MX440F256H-80I/MR benefit embedded system designers?
The integrated USB OTG controller in PIC32MX440F256H-80I/MR allows the device to operate as either a USB host or a USB device without an external USB bridge or hub chip. This makes it suitable for handheld instruments that must read from USB thumb drives as a host and appear as a virtual COM port or HID device to a PC as a device, cutting external component count by 2 to 4 parts.
What ADC resolution does PIC32MX440F256H-80I/MR provide and how many channels are available?
PIC32MX440F256H-80I/MR includes a 10-bit ADC module. The PIC32MX4 family typically provides up to 16 analog input channels multiplexed into this ADC, supporting simultaneous sampling of sensor signals such as temperature, pressure, and current in industrial monitoring applications with a full-scale resolution of 1024 counts.
What is the lead time for PIC32MX440F256H-80I/MR and what procurement strategy is recommended?
PIC32MX440F256H-80I/MR has a factory lead time of approximately 7 weeks from Microchip, which is within the typical range for microcontrollers. Buyers should place orders 8 to 10 weeks ahead of production start dates and maintain a buffer stock of 4 to 6 weeks to guard against demand spikes, particularly for the 64-pin QFN variant which can experience tighter allocation than DIP alternatives.
