PIC32MX130F064D-I/TL Overview
A 32-bit microcontroller (MCU) is a single-chip computer that integrates a 32-bit CPU core, program memory (Flash), data memory (SRAM), and a configurable set of peripherals (timers, ADC, communication interfaces). Within the broader taxonomy, a PIC32MX MCU sits in the hierarchy: PIC32MX -> PIC32 family -> MIPS32 architecture -> 32-bit MCU -> microcontroller -> embedded processor -> semiconductor. Microchip PIC32MX parts target low-power, mixed-signal embedded designs that need more compute headroom than 8/16-bit MCUs without jumping to Cortex-M4.
Key features of the PIC32MX130F064D include two I2S/SPI modules for codec and audio interfaces, a Parallel Master Port (PMP) for graphics, Peripheral Pin Select (PPS) for flexible signal routing, mTouch capacitive-touch support, a Charge Time Measurement Unit (CTMU) for high-resolution (1 ns) time measurement, on-chip temperature sensing, and a Real-Time Clock and Calendar (RTCC). The CTMU plus mTouch combination is distinctive to PIC32MX1xx/2xx parts and enables cost-effective touch and capacitive sensing.
Typical applications include low-cost audio peripherals, graphics interfaces, capacitive-touch user interfaces, USB device classes, sensor hubs, industrial HMI panels, and low-power consumer devices. With 64 KB Flash it comfortably fits USB stacks plus an RTOS or firmware framework.
Design consideration: the VTLA (6x6 mm) package is small but does not have an exposed pad for thermal dissipation; route power/ground generously and follow Microchip's recommended decoupling (100 nF + 1 uF close to VDD/VSS). For higher-pin-count migration within the family, consider the PIC32MX150/170/1xx/2xx 64-pin variants.

Typical Applications
PIC32MX130F064D-I/TL is suitable for 8 applications: Audio DAC and I2S Interface, Graphics Display with PMP, Capacitive Touch User Interface, Sensor Hub with RTCC Logging, Industrial HMI Front Panel, Consumer Wearable Device, Time-of-Flight Range Finder, Low-Cost USB Audio Bridge.
Audio DAC and I2S Interface
The PIC32MX130F064D-I/TL is well matched for low-cost audio peripherals thanks to its two I2S/SPI modules that drive external DACs and codecs at sample rates up to 192 kHz. With 64 KB Flash the firmware can host a USB Audio device stack (when paired with a USB-capable variant) or a simple audio playback engine. Place a 100 nF decoupling cap close to each VDD/VSS pair and route I2S clock and data lines with matched impedance to avoid jitter that would degrade THD+N. The 40 MHz MIPS32 M4K core leaves enough headroom for FFT-based DSP effects.
Recommended
Graphics Display with PMP
The PIC32MX130F064D-I/TL's Parallel Master Port (PMP) drives small TFT/STN displays with 8/16-bit data and a dedicated chip-select/control bus. With 21 GPIO and PPS, designers can map the PMP to any pin set, simplifying PCB layout. The 40 MHz CPU delivers sufficient bandwidth for monochrome QVGA at 30 fps refresh without DMA. Designers should reserve one timer for backlight PWM and use an external boost converter (e.g., TPS61040) to drive LED backlight strings from the same 3.3 V rail.
Recommended
Capacitive Touch User Interface
The PIC32MX130F064D-I/TL integrates Microchip's CTMU (Charge Time Measurement Unit) and mTouch library, supporting capacitive touch buttons, sliders, and wheels with 1 ns time resolution. CTMU charges a capacitive sense line and measures the discharge time via the ADC, producing noise-immune touch detection. The 16 KB SRAM holds the mTouch state machine, while 64 KB Flash accommodates the USB stack if the device acts as a touch HID device. Decoupling close to AVDD is critical - place a 10 uF + 100 nF pair on the analog rail.
Recommended
Sensor Hub with RTCC Logging
The PIC32MX130F064D-I/TL integrates an RTCC with on-chip temperature sensor, making it suitable for low-power sensor hubs that timestamp readings and log them to an external EEPROM or SPI Flash. The MIPS32 M4K core runs at 40 MHz with sub-0.5 mA/MHz active current, allowing battery-powered deployments. PPS lets I2C/SPI peripherals share pins with GPIOs. For low-power sleep, the RTCC keeps ticking from a 32.768 kHz crystal and wakes the MCU on alarm.
Recommended
Industrial HMI Front Panel
In an industrial HMI panel the PIC32MX130F064D-I/TL runs mTouch buttons, drives a small TFT via PMP, and communicates over RS-485 or CAN via PPS-routed UART. The industrial -40 C to +85 C operating range ensures the part survives factory floor conditions. Designers should add a TVS diode (e.g., SMBJ33CA) on the 24 V supply input and follow IEC 61000-4-2 ESD layout practices for the touch electrodes.
Recommended
Consumer Wearable Device
Battery-powered wearables benefit from the PIC32MX130F064D-I/TL's <0.5 mA/MHz active current and mTouch support for buttons/swipe gestures. The 44-VTLA package (6x6 mm) fits compact enclosures. Pair the MCU with a low-power BLE module (e.g., nRF8001) over UART to provide wireless connectivity. Implement sleep modes aggressively - shut down the core between RTCC wakes and gate sensor power rails via a load switch to extend battery life into weeks of standby.
Recommended
Time-of-Flight Range Finder
The PIC32MX130F064D-I/TL's CTMU enables sub-nanosecond time-of-flight ranging when paired with an external current source and photodiode amplifier. The 40 MHz CPU runs the CTMU state machine and outputs range via UART. Designers must keep the analog front-end short and shielded, and route CTMU traces away from switching nodes. PPS lets the CTMU pad sit adjacent to the analog mux, improving noise performance.
Recommended
Low-Cost USB Audio Bridge
Although the PIC32MX130F064D-I/TL lacks native USB hardware, the same-family PIC32MX250F128D upgrade path adds full-speed USB OTG. The PIC32MX130F064D-I/TL still serves as a cost-optimized I2S/CODEC controller with PMP display passthrough in USB audio docks. For drop-in USB capability, choose PIC32MX170F256D or PIC32MX250F128D, both in the same 44-VTLA footprint, with full-speed USB OTG and 128-256 KB Flash.

Key Differentiators
- Includes CTMU and mTouch library in a 44-VTLA footprint (vs PIC32MX110F016D-I/PT)
- Higher Flash density than the smallest PIC32MX1xx 44-pin part (vs PIC32MX110F016D-I/PT)
- Same 44-VTLA footprint as USB-capable variants for upgrade path (vs PIC32MX170F256D-I/TL)
Design Notes
Estimated: at 40 MHz full-load CPU activity, the PIC32MX130F064D-I/TL draws approximately 20 mA from a 3.3 V supply (per the <0.5 mA/MHz active current spec from the family datasheet). Add 100 nF + 1 uF ceramic decoupling close to each VDD/VSS pair; place a 10 uF bulk capacitor at the regulator output. The on-chip LDO supplying the core is internal and does not need external passives, but keep its input rail clean.
The 44-pin VTLA (6x6 mm, 0.65 mm pitch) is a leadless package and is more sensitive to PCB layout than QFP. Use NSMD (non-solder mask defined) pads with 0.3-0.4 mm stencil apertures; reflow profile should follow JEDEC J-STD-020 MSL3/245C. A 4-layer PCB with a continuous ground plane beneath the part improves thermal dissipation and reduces EMI on the PMP bus.
When routing the PMP bus to an external TFT, keep trace lengths matched within 5 mm to preserve setup/hold margins at 40 MHz. Use series damping resistors (22-33 ohm) close to the MCU on clock and data lines to reduce overshoot. Route the I2S MCLK and BCLK traces with controlled impedance (50 ohm single-ended) and avoid running them parallel to switching power traces for more than 5 mm.
Do not confuse the I (industrial) and E (extended) temperature suffixes - the PIC32MX130F064D-I/TL is -40 C to +85 C, not -40 C to +125 C. Always specify the ICSP programming pins (PGECx/PGEDx) as remappable via PPS before locking pin assignments. Ensure AVDD is decoupled separately from VDD; shared decoupling introduces ADC noise that corrupts CTMU touch measurements.
Compliance Information
RoHS and REACH compliance per Microchip environmental declarations. Lead-free NiPdAu terminations on VTLA package. Industrial -40C to +85C grade - not AEC-Q100 qualified for automotive applications.
