Frequently Asked Questions
What is the maximum clock speed of PIC32MX664F064H-I/MR and how does it benefit real-time control loops?
PIC32MX664F064H-I/MR operates at up to 80 MHz on its MIPS32 M4K core, delivering up to 80 DMIPS of processing throughput. This enables PID control loops executing in under 10 µs and simultaneous management of USB 2.0 Full Speed and 10/100 Ethernet MAC traffic without stalling time-critical interrupt service routines in industrial automation applications.
How does the integrated USB and Ethernet in PIC32MX664F064H-I/MR reduce BOM cost versus external bridge ICs?
By integrating both a USB 2.0 Full Speed transceiver and a 10/100 Ethernet MAC on-chip, PIC32MX664F064H-I/MR eliminates one or two external interface bridge ICs that would otherwise cost 0.50 USD to 2 USD each. This single-chip integration also removes up to 20 passive components from the PCB and reduces board area in the 64-pin QFN package by consolidating two communication subsystems.
What memory configuration does PIC32MX664F064H-I/MR offer for running a TCP/IP stack alongside application code?
The device provides 64 KB of Flash program memory and 32 KB of SRAM, sufficient to host a lightweight TCP/IP stack such as Microchip's TCPIP stack alongside Modbus or USB CDC application code. For larger stacks or data buffers, the DMA controller can transfer Ethernet frames to SRAM at 80 MHz without consuming CPU cycles, freeing the MIPS32 core for application logic.
Which package does PIC32MX664F064H-I/MR use and what thermal considerations apply to industrial deployment?
PIC32MX664F064H-I/MR is available in a 64-pin QFN package measuring approximately 9 mm × 9 mm with an exposed thermal pad that reduces junction-to-ambient thermal resistance to below 25°C/W. This allows sustained 80 MHz operation in -40°C to 85°C industrial environments without a heatsink, provided the PCB copper pour around the thermal pad covers at least 4 cm² of copper area on a standard FR4 board.
