Applications
The PIC32MX664F064L-I/PF targets networked industrial control systems and smart gateways that require simultaneous USB device/host and Ethernet connectivity within a single 32-bit microcontroller, such as energy monitors, building automation controllers, and industrial HMIs. The 4-channel DMA allows high-throughput data transfers between USB, Ethernet, and SPI peripherals without stalling the 50 MHz MIPS core, enabling real-time protocol bridging. Its 100-pin TQFP package also suits complex interface boards where many I/O lines are needed for sensor aggregation and actuator control in factory automation systems.

Frequently Asked Questions
Does PIC32MX664F064L-I/PF support USB host mode, and what speed does it operate at?
Yes, the PIC32MX664F064L-I/PF integrates a USB 2.0 OTG controller supporting both full-speed device and host modes at 12 Mbit/s. In host mode, the MCU can enumerate and communicate with USB flash drives, HID keyboards, and CDC serial devices, enabling embedded logging applications or operator interface panels without a dedicated USB host controller IC, saving BOM cost and simplifying firmware using Microchip's Harmony USB stack.
What Ethernet capability does PIC32MX664F064L-I/PF provide for network-connected embedded designs?
The PIC32MX664F064L-I/PF integrates a 10/100 Mbit/s Ethernet MAC with MII and RMII interfaces, requiring only an external PHY transceiver (such as KSZ8041 or DP83848) to complete a full Ethernet node. The MAC supports full-duplex operation, auto-MDIX, and hardware CRC generation for frames, enabling TCP/IP stacks and Modbus TCP applications at 50 MHz MIPS performance without off-chip Ethernet controllers.
How does the 4-channel DMA in PIC32MX664F064L-I/PF improve data throughput for USB and Ethernet bridging?
The 4-channel DMA controller transfers data directly between peripherals and SRAM at up to 32-bit width without CPU intervention, freeing the 50 MHz MIPS32 core from interrupt-driven byte copying. For a USB-to-Ethernet bridge transferring 1 KB packets, DMA can move data in approximately 250 32-bit cycles compared to the thousands of CPU cycles needed by software loops, enabling near-line-rate 12 Mbit/s USB throughput while the CPU handles protocol logic.
For a legacy board refresh, how compatible is PIC32MX664F064L-I/PF with other PIC32MX family members in the same 100-pin TQFP footprint?
PIC32MX664F064L-I/PF uses the TQFP-100 package and is pin-compatible with other PIC32MX devices in the 100-pin footprint, including PIC32MX664F128L and PIC32MX795F512L. Upgrading to a higher-Flash variant such as PIC32MX795F512L (512 KB Flash) typically requires only a compiler relink and device configuration bit update, with no PCB changes, making it straightforward to scale firmware capacity or add features without a board re-spin.
