Frequently Asked Questions
What is the maximum clock frequency and memory configuration of PIC32MX664F128L-I/PF?
PIC32MX664F128L-I/PF runs at up to 50 MHz with 128 KB Flash program memory and 32 KB SRAM, providing sufficient throughput for TCP/IP stacks, USB middleware, and real-time control loops within its 100-pin TQFP package.
How does the 4-channel DMA in PIC32MX664F128L-I/PF improve Ethernet and USB data throughput?
The 4-channel DMA in PIC32MX664F128L-I/PF transfers data autonomously between the 10/100 Ethernet MAC, USB FIFO, UART, and SRAM without CPU cycles, enabling full-speed USB 2.0 transfers and 100 Mbps Ethernet packet handling simultaneously while the 50 MHz MIPS core runs application firmware.
How does PIC32MX664F128L-I/PF compare to PIC32MX664F064L for networked embedded designs?
PIC32MX664F128L-I/PF doubles the Flash capacity to 128 KB versus the 64 KB of PIC32MX664F064L, while both share the same 50 MHz MIPS core, 32 KB SRAM, USB OTG, Ethernet MAC, and 100-pin TQFP footprint, making the 128L variant preferable for applications carrying larger TCP/IP protocol stacks or bootloader plus application firmware.
