Applications
The PIC32MX250F256L-I/PT is designed for 32-bit embedded applications requiring a broad set of communication and measurement peripherals, including audio interfaces, capacitive touch panels, and multi-channel analog acquisition. It is well-suited for industrial HMI controllers, audio playback systems, and sensor fusion nodes where the 32-bit MIPS core running at up to 40 MHz provides headroom for DSP-like operations. The 100-pin TQFP footprint accommodates high I/O count designs while keeping PCB routing manageable on a 4-layer board.

Frequently Asked Questions
How much program and data memory does the PIC32MX250F256L-I/PT provide for firmware development?
The PIC32MX250F256L-I/PT provides 256 KB of Flash program memory plus an additional 3 KB of dedicated boot Flash for bootloader code, along with 32 KB of SRAM for runtime data. This memory configuration supports firmware images compiled with Microchip Harmony or FreeRTOS, including USB stacks and audio codecs that typically require 50 KB to 150 KB of Flash and 8 KB to 20 KB of RAM.
Which audio interface does the PIC32MX250F256L-I/PT support and at what sample rates?
The PIC32MX250F256L-I/PT integrates an I2S (Inter-IC Sound) interface capable of streaming 16-bit and 24-bit digital audio at standard sample rates including 44.1 kHz, 48 kHz, and 96 kHz. This allows direct connection to I2S DAC or codec ICs such as the CS4344 or PCM5102 for audio playback without an intermediate serial-to-parallel converter, reducing BOM complexity in portable speakers, voice recorders, and digital audio workstations.
How does the CTMU peripheral in the PIC32MX250F256L-I/PT enable capacitive touch sensing?
The Charge Time Measurement Unit (CTMU) generates a programmable constant current source that charges a capacitive sense electrode; the MCU's 10-bit ADC then measures the resulting voltage to determine capacitance changes as small as a few picofarads when a finger approaches. A single CTMU peripheral can scan multiple touch buttons by multiplexing the current source across different ADC input channels, enabling a 16-key touch panel from a single peripheral without a dedicated touch controller IC.
For a design requiring boundary scan testing, how does the TQFP-100 package of the PIC32MX250F256L-I/PT support production testing?
The PIC32MX250F256L-I/PT includes a JTAG boundary scan interface compliant with IEEE 1149.1, using 4 dedicated pins (TDI, TDO, TMS, TCK) accessible on the 100-pin TQFP-100 (14×14 mm, 0.5 mm pitch) package. During production automated test equipment can shift a boundary scan chain through all I/O pins to detect solder opens and shorts without physical bed-of-nails probing, reducing test fixture cost for medium-volume PCB assemblies.
