PIC32MX664F128LT-V/BG 概述
A PIC32MX microcontroller belongs to the 32-bit MCU family within the broader category of microcontrollers -> embedded processors -> semiconductors. The PIC32MX5/6/7 series combines a high-performance MIPS32 M4K core with industry-leading connectivity peripherals (Ethernet, USB OTG, CAN) that allow embedded designs to add wired networking and USB device/host/OTG functionality without an external PHY companion. The M4K core executes most instructions in a single cycle and supports the MIPS16e code-compression ISA to maximise code density from the on-chip Flash.
Key specifications for this part include 128 KB Flash program memory organised as 128K x 8, 32 KB SRAM, 80 MHz maximum CPU clock, an integrated 10-bit ADC with up to 16 channels and 1 Msps conversion rate, a 10/100 Mbps Ethernet MAC, USB 2.0 OTG controller with on-chip transceiver, up to 83 programmable I/O pins, and 5 timer/counters. The 121-TFBGA (10x10 mm) package is suited to compact, high-density layouts but requires careful PCB design for the 0.8 mm ball pitch.
Architecturally, the PIC32MX664F128L combines a Harvard-style bus with a unified 32-bit data path, DMA controller for peripheral transfers, and a peripheral pin-select (PPS) engine that remaps digital peripherals to a wide choice of I/O pins, easing board layout. The USB OTG controller includes an integrated physical-layer transceiver, eliminating the need for an external PHY and reducing BOM cost for USB device, host and On-The-Go designs.
Typical applications include industrial Ethernet nodes, USB human-interface devices, building-automation controllers, embedded web servers, and consumer audio accessories. The combination of Ethernet and USB OTG makes this part especially attractive for gateways that bridge USB peripherals onto an IP network. Designers should leverage the MPLAB Harmony software framework and the PIC32MX USB and Ethernet libraries to accelerate firmware development, and verify PCB escape routing for the 0.8 mm BGA balls with manufacturer-recommended design rules.

典型应用
PIC32MX664F128LT-V/BG 适用于 7 应用s: Industrial Ethernet Node, USB OTG Human-Interface Device, Building Automation Controller, Embedded Web Server / IoT Gateway, Consumer Audio Accessory with USB, Data Acquisition Module, Point-of-Sale (POS) Terminal.
Industrial Ethernet Node
The PIC32MX664F128LT-V/BG is purpose-built for industrial Ethernet nodes thanks to its integrated 10/100 Mbps MAC, 80 MHz MIPS32 M4K core, and 32 KB SRAM that comfortably holds a lightweight TCP/IP stack such as Microchip's MLA or Harmony netPreserve. The MAC pairs with an external PHY (e.g. LAN8720A or DP83848) via RMII, while the 128 KB Flash stores both application firmware and a TLS library. The 10-bit ADC and 83 I/O pins handle sensor reads and digital control in the same node, eliminating a companion MCU.
推荐
USB OTG Human-Interface Device
With an integrated USB 2.0 OTG controller and on-chip transceiver, the PIC32MX664F128LT-V/BG serves as a single-chip USB HID, CDC, or mass-storage device without an external PHY. The 80 MHz core easily handles USB polling and HID report generation, while DMA offloads endpoint transfers from the CPU. The 121-TFBGA package fits slim consumer peripherals, and Microchip's USB stack under MPLAB Harmony reduces firmware development time.
推荐
Building Automation Controller
Building-automation controllers benefit from the PIC32MX664F128LT-V/BG's combination of Ethernet, USB OTG, multiple timers, and 16-channel 10-bit ADC for sensor aggregation. The 128 KB Flash stores BACnet or Modbus firmware plus a web configuration interface, while peripheral pin-select (PPS) lets designers remap UART, SPI, and I2C peripherals to convenient pins without re-routing the PCB.
推荐
Embedded Web Server / IoT Gateway
The PIC32MX664F128LT-V/BG combines USB OTG device/host and Ethernet in a single MCU, making it ideal for IoT gateways that bridge USB peripherals onto an IP network. The 80 MHz core runs an HTTP server with REST API, while DMA-driven Ethernet accelerates bulk transfers. The 32 KB SRAM is sufficient for embedded TCP/IP stacks; the 128 KB Flash accommodates both firmware and a small file system for configuration data.
推荐
Consumer Audio Accessory with USB
USB audio peripherals such as USB speakers, headphones, and DACs can use the PIC32MX664F128LT-V/BG as a USB-device controller that streams audio to an external DAC via I2S. The 121-TFBGA fits compact enclosures, and the USB OTG controller's isochronous endpoints handle low-latency audio streams. The 80 MHz core provides headroom for DSP-style sample-rate conversion if needed.
推荐
Data Acquisition Module
For multi-channel data-acquisition modules, the PIC32MX664F128LT-V/BG provides a 16-channel 10-bit ADC at up to 1 Msps, plus DMA that streams samples directly into RAM without CPU intervention. Ethernet enables real-time data upload to a host PC, while USB OTG supports local storage on a USB thumb drive. The 121-TFBGA package supports compact, high-density PCB designs with both Ethernet and USB connectors.
推荐
Point-of-Sale (POS) Terminal
POS terminals benefit from the PIC32MX664F128LT-V/BG's Ethernet for LAN connectivity, USB OTG for barcode scanners or receipt printers, and 83 I/O pins for keypads and displays. The 80 MHz MIPS core handles transaction encryption, and the 128 KB Flash supports firmware plus a small filesystem. The -40C to +105C operating range covers commercial environments.

设计说明
The 121-TFBGA package uses a 0.8 mm ball pitch, which requires 4-layer or better PCB stack-ups with laser-drilled microvias. Per Microchip's PIC32MX hardware design checklist, place at least four 0.1 uF decoupling capacitors as close as possible to the four VDDCORE/VDD corners, plus a single 10 uF bulk capacitor near the MCU. Route all power and ground balls to inner planes with multiple vias to reduce inductance.
Peripheral Pin Select (PPS) allows remapping of digital peripherals, but analog functions and oscillator pins are fixed. Per the Microchip PIC32MX family datasheet, when routing Ethernet RMII signals, keep trace lengths matched within 50 mils to avoid skew, and place the external PHY within 50 mm of the MCU. USB DP/DM traces require 90-ohm differential impedance and should be routed over a continuous ground plane.
Do not operate the PIC32MX664F128LT-V/BG below 2.3 V or above 3.6 V - this exceeds the absolute maximum and may cause latch-up or permanent damage. Per the family datasheet, the on-chip 1.8 V regulator (VDDCORE) must be bypassed with a 10 uF ceramic plus 0.1 uF ceramic; failure to do so results in unstable core operation. Also ensure the MCLR reset circuit uses a proper 10 kohm pull-up and 0.1 uF capacitor for clean power-on reset.
Estimated: the 121-TFBGA package has a junction-to-ambient thermal resistance of approximately 35-45 C/W on a 4-layer JEDEC test board, depending on copper-pour area. At the 80 MHz maximum clock with all peripherals active, typical power dissipation is below 200 mW, well within the thermal envelope. Designers in enclosed industrial enclosures should still provide at least 1 square inch of copper pour under the BGA for thermal spreading.
