PIC32MX130F064BT-V/SS Overview
A 32-bit microcontroller (MCU) is an integrated circuit that contains a 32-bit processor core, program memory (Flash), data memory (SRAM), and a rich set of on-chip peripherals. Within the broader PIC32MX1XX/2XX 28/36/44-pin family, the PIC32MX130 sits at the entry of the performance tier, sharing its MIPS M4K core with the PIC32MX1xx line but offering less Flash and SRAM than PIC32MX2xx devices. The part hierarchy is: microcontroller -> 32-bit MCU -> embedded processor -> semiconductor. This taxonomy matters because PIC32MX MCUs target graphics, audio, USB, and advanced analog interfaces in cost-sensitive embedded applications.
Key features include 64 KB Flash, 16 KB SRAM, two I2S/SPI modules for codec and serial communications, Peripheral Pin Select (PPS) for flexible pin mapping, a Parallel Master Port (PMP) for graphics interfaces, mTouch capacitive touch support, 1 ns high-resolution time measurement via the Charge Time Measurement Unit (CTMU), and on-chip temperature measurement capability. It supports 21 I/O ports with multiple 16-bit timers and a 10-bit ADC.
The PIC32MX130 uses a 5-stage pipeline MIPS32 M4K core capable of 1.56 DMIPS/MHz, providing deterministic real-time response for industrial and consumer applications. Operating from 2.3V to 3.6V, it is fully compatible with 3.3V system buses. The 28-SSOP package offers a small footprint suitable for compact consumer electronics, sensors, and HMI panels.
Typical applications include consumer audio devices, capacitive touch user interfaces, low-cost graphics terminals, sensor hubs, and automotive body controllers (where the -V grade is required). The 64 KB Flash and 16 KB SRAM balance code density and buffer space for small RTOS or bare-metal implementations.
When designing with this part, note that the -V grade supports the full -40C to +105C automotive temperature range. The SSOP package has limited thermal dissipation; derate clock speed when ambient temperature exceeds 85C. PPS remapping must be configured before peripheral enable to avoid glitches.

Typical Applications
PIC32MX130F064BT-V/SS is suitable for 6 applications: Automotive Body Controllers, Capacitive Touch User Interfaces, Low-Cost Graphics Terminals, USB Audio Consumer Devices, Sensor Hubs and IoT Edge Nodes, Industrial Control and PLC I/O Modules.
Automotive Body Controllers
The PIC32MX130F064BT-V/SS suits automotive body controllers with its AEC-Q100 qualification and -40C to +105C operating range. Its 64 KB Flash and 16 KB SRAM run CAN/LIN stacks, body control firmware, and PWM-driven lighting or motor control. The 40 MHz MIPS M4K core executes logic at 1.56 DMIPS/MHz, while 21 PPS-remappable I/O pins connect to switches, LEDs, and H-bridges. mTouch CTMU enables capacitive touch panels for HVAC and infotainment trim controls.

Combined with mTouch firmware libraries, the MCU supports robust water-tolerant touch designs. The 16 KB SRAM buffers touch event histories, and PPS flexibility simplifies PCB layout of touch electrodes to any I/O pin. Automotive grade makes it suitable for in-cabin touch interfaces.
Recommended
Low-Cost Graphics Terminals
The PIC32MX130F064BT-V/SS drives small TFT or OLED displays through its Parallel Master Port (PMP), enabling cost-effective HMI panels in appliances and industrial controls. With 64 KB Flash, designers can fit Microchip's Graphics Object Library or a lightweight LVGL port, while 16 KB SRAM supports frame buffers and widget state. PMP supports 8-bit or 16-bit data paths up to the 40 MHz peripheral clock.
Recommended
USB Audio Consumer Devices
The PIC32MX130F064BT-V/SS integrates two I2S/SPI modules that interface directly to USB audio codecs, supporting USB speakers, headphones, and digital microphones. The 40 MHz MIPS M4K core handles USB stack, audio sample processing, and HID controls, while 16 KB SRAM is sufficient for small audio buffers. AEC-Q100 qualification enables automotive infotainment audio paths where USB input is required.
Recommended
Sensor Hubs and IoT Edge Nodes
The PIC32MX130F064BT-V/SS aggregates data from multiple I2C/SPI sensors via PPS-remappable peripherals, performing local filtering before forwarding over UART, SPI, or CAN. Core current below 0.5 mA/MHz keeps battery-powered sensor nodes efficient. Automotive temperature grade allows outdoor IoT deployments such as agricultural sensors, parking sensors, and EV charging station monitors.
Recommended
Industrial Control and PLC I/O Modules
The PIC32MX130F064BT-V/SS functions as an I/O expander or local controller in PLCs and industrial automation, with 21 GPIO pins driving relays, optocouplers, and digital inputs. PMP and I2S/SPI interfaces connect to higher-speed industrial buses, while the AEC-Q100 grade tolerates factory floor thermal stress. Five 16-bit timers support precise PWM for motor and valve control in process automation.

Key Differentiators
- AEC-Q100 automotive temperature qualification (-40C to +105C) (vs PIC32MX130F064BT-I/SS)
- Tape and reel packaging for high-volume assembly (vs PIC32MX130F064B-I/SS)
- Compact 28-SSOP footprint (vs PIC32MX130F064BT-V/SO)
Design Notes
Estimated: at 40 MHz with all peripherals enabled, core current is approximately 20 mA (0.5 mA/MHz). Add I/O sink/source current and ADC analog supply current for total mA budget. Decouple VDD and AVDD pins with 0.1 uF ceramic capacitors placed within 5 mm of the package pins; use a bulk 4.7 uF tantalum or ceramic at the board entry point. Place VCAP pin capacitor (typically 10 uF) as close as possible to the pin to stabilize the internal 1.8V core regulator.
The 28-SSOP package has limited thermal dissipation and is intended for moderate ambient temperatures. At sustained 40 MHz in a sealed enclosure at 70C ambient, junction temperature rise remains below 30C, but for +105C automotive under-hood operation, ensure PCB copper area around the SSOP exposed paddle (none - SSOP lacks thermal pad) is maximized. Consider the 28-QFN (PIC32MX130F064BT-I/ML) for higher thermal load designs requiring an exposed thermal pad.
Peripheral Pin Select (PPS) mappings must be configured BEFORE enabling the peripheral; otherwise the peripheral may drive an unconfigured pin or remain disconnected. Always unlock the PPS register lock sequence (PPSLOCK) before writing PPS registers. Also note that the CTMU module requires firmware calibration per PCB to compensate for parasitic capacitance on touch electrodes; refer to Microchip application note AN1250 for calibration guidance.
