PIC32MX130F064B-V/SS Overview
A microcontroller (MCU) is a single-chip computer integrating a CPU core, program and data memory, peripherals, and I/O on one piece of silicon. The PIC32MX130 sits in Microchip's PIC32 family, which spans 32-bit MIPS cores used for USB, graphics, and audio applications; within that family it belongs to the PIC32MX1xx/2xx sub-series aimed at cost-constrained general-purpose designs. The PIC32MX130F064B-V/SS therefore functions as a complete system-on-chip for USB devices, audio playback, and small graphics HMI.
Key features include a 40 MHz core with less than 0.5 mA/MHz active current, two I2S/SPI modules for codec interfacing, Peripheral Pin Select (PPS) for flexible signal routing, five 16-bit timers, a 10-bit 1 Msps ADC with up to 13 channels, an on-chip temperature sensor, mTouch capacitive touch support, and CTMU charge-time measurement. USB 2.0 full-speed Device/Host/OTG is integrated, and the PMP block enables direct connection to parallel graphics LCDs, simplifying HMI designs.
The PIC32MX130F064B-V/SS operates from 2.3 V to 3.6 V and is offered in -40 °C to +105 °C (V) and -40 °C to +85 °C (I) grades. The 28-SSOP package exposes 21 GPIO, all remappable through PPS, allowing trade-offs between UART, SPI, I2C, I2S, and timer pins on the fly. The combination of USB, audio, and PMP in a 28-pin footprint differentiates it from smaller PIC32MX110/MX150 parts and from external-USB PIC24 alternatives.
Typical applications include USB audio headsets and DACs, USB HID peripherals, low-cost graphics LCD HMI panels, mTouch capacitive button interfaces, AEC-Q100 body and infotainment sub-modules, and industrial sensor hubs requiring USB device connectivity. The 64 KB Flash / 16 KB SRAM balance suits small USB stacks plus application code.
When designing with this device, choose a 3.3 V LDO capable of at least 60 mA peak (USB-active transients) and place decoupling within 2 mm of each VDD/VSS pair. For USB, route D+/D- as a 90-ohm differential pair and add 15 kohm pull-downs on each line as required by the USB 2.0 specification.

Typical Applications
PIC32MX130F064B-V/SS is suitable for 6 applications: USB Audio Headsets and DACs, USB HID Peripherals, Graphics LCD HMI Panels, mTouch Capacitive Touch Interfaces, Automotive AEC-Q100 Sub-Modules, Industrial Sensor Hubs.
USB Audio Headsets and DACs
The PIC32MX130F064B-V/SS fits USB audio applications because its integrated USB 2.0 full-speed Device controller plus dual I2S modules connect directly to external 24-bit audio codecs without glue logic. According to Microchip datasheet DS60001168L, the 16 KB SRAM is sufficient for stereo 16-bit/48 kHz USB isochronous buffering with headroom for the HID control channel; the 40 MHz MIPS32 M4K core runs the USB stack plus codec driver with MIPS to spare. Place a 12 MHz crystal on OSC1/OSC2 with 20 pF load caps, route D+/D- as a 90-ohm differential pair, and add 15 kohm pull-downs on each line.
Recommended
USB HID Peripherals
For USB keyboards, mice, game controllers, and custom HID devices, the PIC32MX130F064B-V/SS delivers 64 KB Flash for HID report descriptors plus bootloaders, and 21 GPIO with Peripheral Pin Select to map switches, encoders, and LEDs to any pin. The on-chip USB pull-up and full-speed transceiver eliminate external components. The 40 MHz core sustains polling rates up to 1000 Hz on a full HID keyboard matrix, and the 5x16-bit timers handle debouncing and report timing.
Recommended
Graphics LCD HMI Panels
The PIC32MX130F064B-V/SS integrates a Parallel Master Port (PMP) that drives common 8/16-bit parallel graphics LCDs and OLEDs without external bus multiplexers, ideal for small HMI panels up to 320x240 pixels. Combined with the 2x I2S/SPI blocks for touchscreen controllers and the 10-bit ADC for backlight sensing, the part provides a single-chip HMI controller. Use 16-bit PMP mode for 320x240 TFTs to avoid display-tearing artifacts; the 16 KB SRAM holds one full framebuffer at 16-bit color depth.
Recommended
mTouch Capacitive Touch Interfaces
The PIC32MX130F064B-V/SS supports Microchip's mTouch capacitive touch solution through the on-chip CTMU (Charge Time Measurement Unit), which times the charging of touch electrodes with 1 ns resolution. This enables touch buttons, sliders, and proximity sensors without an external touch controller IC, saving BOM cost in appliances and consumer products. The CTMU works with the ADC and PPS to assign touch channels to nearly any pin, and the 10-bit ADC provides enough resolution for slider position interpolation.
Recommended
Automotive AEC-Q100 Sub-Modules
The PIC32MX130F064B-V/SS is AEC-Q100 qualified and operates across -40 C to +105 C, making it suitable for automotive body controllers, HVAC panels, USB charging ports, and infotainment accessories. Its integrated USB supports automotive USB media ports and CarPlay-style accessory hubs; the PMP drives small instrument-cluster graphics. The wide 2.3-3.6 V supply tolerance survives 12 V battery cranking transients when paired with an automotive-grade LDO such as the MCP1790.
Recommended
Industrial Sensor Hubs
Industrial sensor hubs using the PIC32MX130F064B-V/SS benefit from the 10-bit 1 Msps ADC with up to 13 channels for multi-sensor aggregation, plus USB device connectivity for tethering to a host PC or industrial gateway. The two I2S/SPI modules interface to digital sensors and external ADCs; CTMU times pulse outputs from ultrasonic and Time-of-Flight sensors. The 64 KB Flash supports Modbus RTU and CANOpen over USB stacks, and 16 KB RAM buffers sensor log messages between USB transmissions.

Key Differentiators
- Automotive V-grade temperature rating in 28-SSOP (vs PIC32MX130F064B-I/SS)
- Cost-optimized 64 KB Flash in 28-SSOP with USB (vs PIC32MX170F256B-V/SS)
- Parallel Master Port integrated in 28-SSOP (vs PIC24FJ64GB002 (PIC24 family))
Design Notes
Power the PIC32MX130F064B-V/SS from a 3.3 V LDO capable of at least 60 mA peak to absorb USB-active transients and oscillator startup surges. Place a 10 uF bulk ceramic plus 0.1 uF decoupling capacitor within 2 mm of each VDD/VSS pin pair; the VUSB pin requires its own 0.1 uF decoupling. For USB battery-powered designs, use an LDO with <30 uVrms noise to keep the USB D+/D- common-mode voltage within the 2.0 specification.
Route the USB D+ and D- traces as a 90-ohm differential pair with matched length within 2 mm; keep total trace length under 50 mm and isolate from switching signals with a ground pour. For PMP parallel graphics LCD interfaces, keep the 8/16-bit data bus under 100 mm and place a 33 ohm series damping resistor near the MCU. Place the 12 MHz crystal within 5 mm of OSC1/OSC2 with grounded guard ring on all sides to suppress radiated EMI.
Do not skip the VBUS sensing circuit when implementing USB Device mode - without it the USB stack cannot detect attachment. When using Peripheral Pin Select (PPS), ensure the input function is unmapped and output function assigned before configuring the GPIO as digital; otherwise peripherals will not respond. Estimated: at 40 MHz, 3.3V, full USB activity, the part draws approximately 20 mA (0.5 mA/MHz x 40 MHz). Always configure the JTAG/ICSP pins as GPIO through CONFIG bits if not used, otherwise PGEC1/PGED1 remain in programming mode and cannot serve as general I/O.
