PIC32MX564F064L-V/BG Overview
A 32-bit microcontroller is a single-chip computer that integrates a high-performance processor core, program and data memory, and a configurable peripheral set. The PIC32MX5xx family is positioned in Microchip's mid-range 32-bit MCU portfolio, balancing MIPS performance with the familiar PIC ecosystem (MPLAB X IDE, Harmony framework, and a broad library of code examples). This family sits hierarchically between the lower-end PIC32MX1xx/2xx and higher-end PIC32MX7xx devices, targeting USB-enabled consumer, industrial, and IoT applications.
Key features of the PIC32MX564F064L-V/BG include hardware DMA, dedicated USB OTG with on-chip transceiver, parallel master port (PMP) for external bus expansion, five 16-bit timers, two I2C and two SPI/I2S peripherals, and up to four UART channels. The device offers 87 GPIO pins and supports JTAG/ICSP debugging. Architectural highlights include 5-stage pipeline MIPS32 M4K core with single-cycle multiply and hardware divide, prefetch cache for Flash acceleration, and a flexible clock tree with multiple oscillator options including an on-chip 8 MHz RC and 32 kHz secondary oscillator.
Typical applications include USB peripherals (HID, CDC, mass storage, audio class), industrial control with real-time sensor acquisition via DMA, embedded HMI with PMP-driven LCDs, and connected IoT bridges that require full-speed USB for tethering to a host. The combination of DMA, USB OTG, and ample peripherals allows firmware developers to offload data movement and run deterministic code paths.
When designing with the PIC32MX564F064L-V/BG, place decoupling capacitors close to every VDDCORE/VDD pin pair and use a 6-layer PCB with a solid ground plane for the 121-ball BGA fan-out. The integrated USB PHY requires a 48 MHz clock derived from the system PLL, and impedance-controlled USB traces (90 ohm differential) are required for full-speed USB compliance.

Typical Applications
PIC32MX564F064L-V/BG is suitable for 6 applications: USB HID Peripherals (Keyboard/Mouse/Gamepad), Industrial Sensor Acquisition with DMA, Embedded HMI with Parallel LCD, USB Tethered IoT Bridge, Audio Class USB Streaming Device, Battery-Powered Data Logger.
USB HID Peripherals (Keyboard/Mouse/Gamepad)
The PIC32MX564F064L-V/BG's integrated USB 2.0 Full-Speed OTG controller with on-chip PHY makes it ideal for USB Human Interface Device peripherals. With 80 MHz of MIPS32 M4K performance and DMA-driven endpoint handling, it can service multiple HID report descriptors without CPU bottlenecks. The 87 GPIO pins are sufficient for matrix-scanned keyboards, while the 32 KB SRAM comfortably accommodates USB descriptors and HID report buffers. Pair this MCU with an external ESD protection array (USBLC6-2SC6) and 90 ohm differential routing for full-speed compliance, and use Microchip's USB stack from MPLAB Harmony for rapid HID enumeration.
Recommended
Industrial Sensor Acquisition with DMA
The PIC32MX564F064L-V/BG's 10-bit 1 Msps ADC with 16 input channels and dedicated 8-channel DMA controller suits industrial multi-sensor acquisition nodes. The DMA can stream ADC conversions into SRAM buffers while the CPU runs control loops, freeing bandwidth for CAN-style communication or RS-485 fieldbus stacks. The -40 C to +105 C temperature grade (V variant) supports factory-floor deployment. Use the dual I2C/SPI peripherals to attach digital sensors, and add an external 4-20 mA loop driver for legacy analog instrumentation.
Recommended
Embedded HMI with Parallel LCD
The PIC32MX564F064L-V/BG integrates a Parallel Master Port (PMP) that can directly drive TFT LCD panels up to 8-bit bus width, ideal for embedded HMI terminals and control panels. The 80 MHz core delivers enough throughput to refresh QVGA panels while leaving cycles for touch-screen scanning and UI logic. Connect the panel via the PMP data lines, use one of the 16-bit timers for backlight PWM dimming, and stack an XPT2046 touch controller over SPI for capacitive touch input. The 64 KB Flash holds lightweight graphics libraries, with 32 KB SRAM providing double-buffered framebuffers for small displays.
Recommended
USB Tethered IoT Bridge
The PIC32MX564F064L-V/BG's USB OTG dual-role capability allows it to act as a USB-tethered IoT bridge that presents WiFi or sensor telemetry to a host PC or smartphone. The on-chip PHY eliminates external USB components, while 87 GPIO can fan out to UART/I2C/SPI peripherals aggregated into a single USB CDC-ACM or vendor-class interface. The 32 KB SRAM accommodates multi-channel data buffers, and the DMA engine offloads protocol framing. Deploy this configuration in field-tooling kits, OEM configuration programmers, or low-cost data loggers that connect to a host for visualisation.
Recommended
Audio Class USB Streaming Device
The PIC32MX564F064L-V/BG can implement USB Audio Class 1.0 streaming for low-bandwidth speakers, headsets, or intercom endpoints. With 80 MHz MIPS performance it sustains 48 kHz / 16-bit stereo USB audio without dropping packets, and the I2S peripheral feeds external DACs (e.g., PCM5102A) directly. The DMA engine handles USB endpoint-to-I2S data movement, freeing the CPU for volume control and effect processing. Add a small Class-D amplifier downstream of the DAC, and use the PIC's PWM for headphone sidetone mixing in headset designs.
Recommended
Battery-Powered Data Logger
The PIC32MX564F064L-V/BG's 2.3-3.6 V supply range and low-power sleep modes support battery-powered data loggers with USB charging. The on-chip 8 MHz RC and 32 kHz secondary oscillator provide a low-power timebase for RTC-style time-stamping, while the DMA-driven ADC captures sensor bursts without waking the CPU repeatedly. The 64 KB Flash stores firmware and small lookup tables, and the 32 KB SRAM buffers burst samples before periodic USB dump. Pair this MCU with a Li-Ion charger (MCP73831) and a current-sense amplifier for accurate battery telemetry.

Key Differentiators
- Integrated USB 2.0 OTG PHY in 121-TFBGA (vs PIC32MX534F064L-I/BG (same family, no USB))
- 8-channel DMA engine (vs PIC32MX460F512L-80V/BG (4-channel DMA, larger Flash))
- V temperature grade -40C to +105C (vs PIC32MX564F064L-I/BG (I grade -40C to +85C))
Design Notes
The 121-ball TFBGA at 0.8 mm pitch requires a 4-layer PCB minimum with 1 oz copper and laser-drilled or 0.3 mm mechanical vias. Use microvia stackups (via-in-pad) where routing density demands it, but ensure the fab applies a copper-fill planarisation step to prevent ball voiding. A solid ground plane directly under the BGA is essential for USB signal integrity, and all VDD/VDDCORE pin pairs must have 100 nF X7R decoupling within 2 mm of the ball, plus a 4.7 uF bulk capacitor near the regulator. Estimated: a 6-layer 1.6 mm FR-4 stackup yields roughly 50 ohm single-ended impedance with 0.10 mm trace and 0.20 mm spacing.
Do not skip the 32.768 kHz secondary oscillator load capacitors - the USB SOF frame timing and RTCC depend on it. The internal 1.8 V regulator requires a 10 uF bulk capacitor on VDDCORE; omitting it can cause brown-out resets under DMA bursts. The USB D+/D- traces must be 90 ohm differential with no stubs, and the VBUS sense pin must be tied through a divider to a 5 V-tolerant GPIO if you intend to detect host power. Estimated: a 90 ohm differential on 0.10 mm traces with 0.18 mm spacing on FR-4 with Er=4.3 is roughly correct.
At 80 MHz the PIC32MX564F064L-V/BG dissipates roughly 60-80 mW typical; the 121-TFBGA with a centre ball grid achieves theta_JA around 25 C/W on a JEDEC 4-layer test board. This puts junction-to-ambient rise at only 2 C/W under typical load, so no heatsink is required. However, in enclosed industrial enclosures above 70 C ambient, derate by 5 mW per C to stay within the 105 C upper limit. Estimated: P_total = 0.075 W, delta_T = 1.9 C above ambient on the standard test board.
The Parallel Master Port (PMP) bus can run up to 80 MHz internally, but external timing is constrained by pin capacitance and loading. Keep PMP traces under 50 mm, add 22 ohm series damping resistors on data and strobe lines, and use a single ground reference for the LCD connector return path. For USB, keep D+/D- matched within 0.5 mm and route over a continuous ground plane with no splits. Estimated: at 50 mm and 5 pF pin/connector load, edge rates degrade approximately 10-15%.
