PIC32MX130F064BT-I/ML Overview
A 32-bit microcontroller (MCU) is an integrated processor core, program memory (Flash), data memory (SRAM), and a rich set of peripherals on a single silicon die. The PIC32MX family sits in Microchip's hierarchy of 32-bit MIPS-based MCUs under the broader PIC microcontroller product line, which itself falls under the semiconductor taxonomy of embedded processors. 32-bit MCUs are typically used when applications require more computational throughput, larger addressable memory, or richer peripheral integration than 8-bit/16-bit MCUs can deliver.
Key features include 64 KB Flash program memory, 16 KB SRAM, USB 2.0 full-speed device, two I2S/SPI modules for codec/serial communication, Peripheral Pin Select (PPS) for flexible pin mapping, a Parallel Master Port (PMP) for graphics interfaces, mTouch capacitive touch support, on-chip temperature measurement, and Charge Time Measurement Unit (CTMU) with 1 ns high-resolution time measurement capability. The PIC32MX130 operates from 2.3V to 3.6V with less than 0.5 mA/MHz active current consumption.
The PIC32MX130 uses a 5-stage pipeline MIPS32 M4K core with single-cycle multiplication, hardware multiply-accumulate, and an instruction set that is highly optimized for C code density. The integrated USB 2.0 full-speed device, combined with PMP for TFT/LCD graphics, makes the PIC32MX130 a strong fit for low-cost graphical user interfaces with USB connectivity.
Typical applications include consumer audio accessories with USB, low-cost graphical display modules (PMP + TFT), mTouch capacitive touch key panels, USB peripherals, industrial sensor nodes with on-chip temperature compensation, and embedded control in home appliances. The 28-QFN package is well suited for space-constrained designs.
When designing with this part, plan the Peripheral Pin Select mapping before laying out the PCB, as remapping a peripheral later can require substantial rework. The QFN thermal pad must be soldered to a sufficient copper pour to meet the datasheet thermal derating curves.

Typical Applications
PIC32MX130F064BT-I/ML is suitable for 6 applications: USB Consumer Audio Accessory, Low-Cost Graphical Display Module (PMP + TFT), mTouch Capacitive Touch Key Panel, USB Peripherals and HID Devices, Industrial Sensor Node with Temperature Compensation, Home Appliance and White-Goods Control.
USB Consumer Audio Accessory
The PIC32MX130F064BT-I/ML fits USB audio accessories because it integrates a USB 2.0 full-speed device and two I2S/SPI modules on a single die. With 40 MHz MIPS32 throughput and 16 KB SRAM it can sustain stereo 16-bit audio at 48 kSPS over USB isochronous endpoints while driving an external DAC over I2S. Compared with discrete USB plus DSP solutions, this single-chip approach saves 4-6 cm^2 of board area and removes one IC from the BOM. Use it for headphones, USB speakers, or USB-to-I2S bridges where low cost and small footprint matter more than 24-bit high-res audio.
Recommended
Low-Cost Graphical Display Module (PMP + TFT)
The PIC32MX130F064BT-I/ML drives small TFT displays through its on-chip Parallel Master Port (PMP) at up to 40 MHz, which is enough bandwidth to refresh QVGA (320x240) panels without external controllers. Its 16 KB SRAM supports a modest double-buffered frame buffer, while Peripheral Pin Select (PPS) lets the designer remap PMP data lines to free analog-capable pins for touch sensing. The 28-QFN 6x6 mm footprint fits underneath the display tail, ideal for appliance HMIs and instrumentation front panels. For higher resolution or full-color graphics consider the PIC32MX250/270 family instead.
Recommended
mTouch Capacitive Touch Key Panel
The PIC32MX130F064BT-I/ML supports Microchip's mTouch capacitive touch via the integrated CTMU and on-chip temperature sensor. CTMU provides 1 ns resolution charge-time measurement, which is more than adequate for reliable proximity and touch key decoding across 8-16 electrodes. The 64 KB Flash easily stores reference firmware plus custom tuning tables, while PPS lets the designer place electrodes on convenient GPIO without disturbing the analog channels. Typical applications include kitchen appliances, audio front panels, and any sealed-surface user interface.
Recommended
USB Peripherals and HID Devices
The PIC32MX130F064BT-I/ML is well suited to USB HID-class peripherals such as custom keypads, game controllers, sensor HID devices, and configuration tools. Its on-chip USB 2.0 full-speed device, 21 GPIO, and Peripheral Pin Select (PPS) allow most USB HID descriptors to be implemented with no external glue logic. With active current under 0.5 mA/MHz at 40 MHz it draws less than 20 mA active, well within USB bus-powered budgets. The 28-QFN 6x6 mm package fits dongle-style enclosures.
Recommended
Industrial Sensor Node with Temperature Compensation
The PIC32MX130F064BT-I/ML integrates an on-chip temperature sensor that can be read through the ADC, simplifying designs that need cold-loop or thermal-drift compensation. Combined with 64 KB Flash for sensor-fusion firmware and CTMU for precision timing of measurements, it is well suited to industrial 4-20 mA sensor heads, environmental monitors, and HVAC transmitters. Industrial temperature grade (-40 C to +85 C) covers most factory-floor environments; for outdoor extended range the PIC32MX130F064B-V/ML (105 C) variant is preferred.
Recommended
Home Appliance and White-Goods Control
The PIC32MX130F064BT-I/ML is a strong fit for low-to-mid-end home appliance control, including washing machine user interfaces, microwave HMI panels, induction cooktop displays, and small kitchen robots. The 64 KB Flash holds both the application and an optional USB bootloader for field updates, while mTouch eliminates mechanical buttons on glass-front panels. PMP drives segment or TFT displays, and CTMU provides robust touch decoding through 3-4 mm glass. Operating from a 3.3 V LDO sourced from the appliance's 5-24 V rail keeps the bill of materials small.

Key Differentiators
- Tape-and-reel packaging for high-volume SMT assembly (vs PIC32MX130F064B-I/ML)
- Extended 105 C operating temperature grade (vs PIC32MX130F064B-V/ML)
- 50 MHz capable silicon variant (vs PIC32MX130F064BT-50I/ML)
Design Notes
The 28-QFN package exposes a central thermal pad that the Microchip PIC32MX1XX/2XX datasheet recommends connecting to VSS externally for thermal dissipation. Place a continuous ground plane beneath the part and stitch vias in the exposed-pad region to a bottom-layer ground pour; failing to solder the thermal pad raises junction-to-ambient thermal resistance and can cause 5-8 C of unexpected temperature rise under full 40 MHz load.
Peripheral Pin Select (PPS) mapping must be configured in firmware before the peripheral is enabled. The default PPS mapping at reset leaves most digital peripherals disconnected from external pins, so a fresh firmware image that skips the PPS unlock sequence will appear as a 'dead' MCU even though the silicon is healthy. Always include the PPS unlock sequence (unlock sequence then write to PPS register) in the startup code before peripheral initialization.
Place a 0.1 uF ceramic decoupling capacitor within 0.04 inches of every VDD pin and a bulk 10 uF ceramic on the main supply trace. The PIC32MX130's 40 MHz core generates transient current spikes that can corrupt analog conversions if the supply is poorly decoupled, particularly for ADC accuracy on the shared analog pins. Add a ferrite bead between the digital 3.3 V rail and the analog AVdd rail if ADC noise is observed.
Keep the 48 MHz USB clock trace short and symmetric, and route USB DP/DM as a 90 ohm differential pair with ground reference on both sides. The PIC32MX130's on-chip USB PHY is sensitive to common-mode noise, so do not run high-current switching traces parallel to the DP/DM pair. If full-speed USB certification is required, an external ESD protection diode array on DP/DM is strongly recommended.
Compliance Information
RoHS and lead-free per Microchip product page; industrial temperature grade is -40 C to +85 C, not AEC-Q100 qualified. For automotive applications use a PIC32MX QFN part qualified under Microchip's automotive flow.
