The PIC32MX3/4 family is built around the MIPS32 M4K core, running up to 120 MHz (150 DMIPS), with an integrated 80 MHz peripheral bus, two I2S/SPI modules for codec and audio peripherals, a Peripheral Pin Select (PPS) block, a Parallel Master Port (PMP) for graphics interfaces, and a Charge Time Measurement Unit (CTMU) for capacitive touch and accurate timing. Operating voltage is 2.3 V to 3.6 V with five programmable power modes that drop current consumption into the microamp range between tasks. What is a PIC32 microcontroller? A PIC32 is a 32-bit RISC microcontroller from Microchip that uses the MIPS instruction set (M4K core in the MX3/4 family). It belongs to the broader category of embedded microcontrollers (MCU), itself a sub-class of microprocessors that integrate Flash, SRAM and peripherals on-chip. Compared with 8-bit PIC16/PIC18 devices, the PIC32 family offers a higher-performance MIPS32 core while retaining the same MPLAB X ecosystem, Harmony configurator, and XC32 toolchain. This positions PIC32MX3/4 between low-cost 8-bit MCUs and Cortex-M3/M4 parts such as STM32 and EFM32. Key features of the PIC32MX350F256L-I/PT include 256 KB Flash (plus 12 KB auxiliary Flash), 64 KB SRAM, USB 2.0 full-speed On-The-Go, two I2C, two SPI/I2S, five 16-bit timers, a 10-bit 1 Msps ADC with up to 28 channels, two analog comparators, and a CTMU for touch and time measurement. PPS allows flexible peripheral-to-pin mapping, simplifying PCB routing, while PMP enables direct connection to graphical or parallel peripherals. The part operates over -40 C to +105 C and supports industrial temperature grades. Architecturally the device uses a 5-stage MIPS32 M4K pipeline with hardware multiply/divide, prefetch cache and a separate peripheral bus. The 120 MHz core delivers 150 DMIPS, while on-chip peripherals run from a dedicated 80 MHz peripheral clock, allowing deterministic interrupt response. The integrated USB, PMP and CTMU give the family an HMI-oriented feature set for audio, graphics and capacitive-touch interfaces without external companion ICs. Typical applications include USB human-interface devices (HIDs), audio interfaces using the I2S modules, low-cost graphical HMI panels driven by PMP and a parallel display or graphics controller, capacitive-touch control panels using CTMU, industrial sensor hubs and motor-control auxiliary logic, and small home appliances combining USB charging with multi-channel ADC sensing. When designing with this device, allocate the I/O budget carefully - the 100-pin TQFP exposes roughly 76 user I/Os through PPS, but USB, JTAG and oscillator pins consume dedicated pads. Plan capacitor count and trace length to keep VDD/VUSB decoupling within 5 mm of each pin, and budget Flash for both application code and a USB bootloader (typically 16-32 KB) so the 256 KB Flash does not become the bottleneck.

The Microchip Technology PIC32MX350F256LT-V/PF is a 32-bit MIPS32 M4K microcontroller running up to 80 MHz with 256 KB of Flash and 64 KB of SRAM, supplied in a 100-pin TQFP (14x14 mm) package. The device integrates two analog comparators, two I2C, two SPI/I2S ports, USB 2.0 full-speed device/host/OTG, a 10-bit 1 Msps ADC with up to 28 input channels, five 16-bit timers/counters, and a Parallel Master Port, providing the I/O density required by mid-range graphical and connectivity-rich embedded designs. The -V suffix designates the V-temp grade (operating range -40 C to +105 C), while the -I grade variant operates -40 C to +85 C. This part is built on the legacy PIC32MX3/4 platform targeted at industrial control, USB peripherals, and graphical user interface applications, and offers a low-cost upgrade path for designers porting from PIC24/PIC32MX1/MX2 families. Background knowledge - what is a PIC32MX3xx microcontroller: The PIC32MX3xx family is part of the broader PIC32MX family of 32-bit microcontrollers built around the MIPS32 M4K core, a Harvard-architecture RISC processor with single-cycle multiply and hardware divide. PIC32MX3xx sits between PIC32MX1/2 (lower pin count, smaller memory) and PIC32MX4/5/6/7 (higher pin count, larger memory and Ethernet). It is positioned in the broader microcontroller taxonomy as a mid-tier MCU: microcontroller -> 32-bit MCU -> MIPS-based MCU -> PIC32 family -> PIC32MX3/4 sub-family. The M4K core delivers 1.53 DMIPS/MHz and up to 150 DMIPS at 80 MHz, giving meaningful headroom for RTOS-driven and DSP-light workloads versus 8-bit PIC16/AVR alternatives. Key specifications include 256 KB Flash (with 12 KB auxiliary Flash for data), 64 KB SRAM, 16 KB USB RAM (accessible to the CPU when USB is not used), an 8 MHz internal oscillator (with PLL up to 80 MHz), and CTMU / mTouch capacitive touch support. The device supports 5V-tolerant I/O, an operating voltage of 2.3V to 3.6V, and is offered in TQFP-100, TQFP-64, QFN-64, and die/die-package options. JTAG and 2-wire programming/debug interfaces are available via the MIPS-standard ICSP and Trace ports. Typical applications include industrial control panels, USB HID/CDC peripherals, low-cost graphical HMI (paired with segmented LCD or color TFT via PMP), motor control companion MCUs, and connected sensor hubs. The V-temp grade specifically suits outdoor enclosures, factory automation, and automotive under-hood-adjacent environments. When designing, ensure the 100-pin TQFP PCB footprint has at least four-layer routing for decoupling and high-speed USB; allow adequate via fan-out under the exposed die pad if migrating to a TQFP variant without EPAD.

PIC32MX350F256LT-V/TL

PIC32MX350F256LT-V/TL - 80MHz 256KB Flash 32-bit MCU | Microchip

The Microchip Technology PIC32MX350F256LT-V/TL is a 32-bit MIPS32 M4K core microcontroller running up to 80MHz, delivering 100 DMIPS performance, with 256KB of Flash program memory and 64KB of SRAM, housed in a 124-pin VTLA (9x9 mm) surface-mount package. The part operates from 2.3V to 3.6V and is qualified to an automotive temperature grade of -40C to +105C, making it well suited for industrial and vehicle body applications. A 32-bit microcontroller (MCU) is an integrated circuit combining a microprocessor core, program memory (Flash), data memory (SRAM), and configurable peripherals in a single chip. The PIC32MX3/4 family sits in Microchip's PIC32 hierarchy: PIC32MX -> 32-bit MCU -> MIPS M4K core -> microcontroller -> embedded processor -> semiconductor. Compared with 8-bit PIC16/AVR MCUs, the PIC32MX350 series adds parallel processing throughput, USB/device connectivity, and Peripheral Pin Select (PPS) remapping to free pin assignments from fixed peripheral mappings. Key features of the PIC32MX350F256LT-V/TL include two I2S/SPI modules for codec and serial audio, two I2C channels, two UART/USART interfaces with IrDA and LIN support, a Parallel Master Port (PMP) for graphics or external memory, a 10-bit ADC with up to 28 analog input channels, two analog comparators, and a Charge Time Measurement Unit (CTMU) for capacitive touch or precise time-of-flight measurement. Five 16-bit timers/counters and a 5-channel DMA controller offload the core and accelerate throughput. The architecture combines a single-cycle MIPS32 M4K pipeline with a tightly-coupled prefetch module and a separate bus for DMA traffic, producing deterministic interrupt latency. PPS remapping of digital I/O and a 124-pin VTLA pad-out expose enough GPIO for parallel buses, multiple SPI/I2S peripherals, and analog channels without external muxing. Hardware multipliers and a 32x16-bit divider accelerate DSP-oriented code such as audio filtering, PID control loops, and sensor fusion. Typical applications include automotive body controllers, LIN/J1939 nodes, industrial HMI panels, USB device peripherals, audio playback and processing with external codecs, and graphics-enabled PMP interfaces. The wide operating voltage and 105C thermal rating also fit battery-management front-ends and metering subsystems. When designing with this part, plan for an external 8MHz crystal and the PLL configuration to reach 80MHz system clock; add 0.1uF decoupling on every VDD/VSS pair and a bulk 10uF tantalum near the regulator. PPS mappings must be locked before enabling peripherals, otherwise peripherals stay on their default pins.

The Microchip Technology PIC32MX360F256L-80I/BG is a 32-bit MIPS32 M4K core microcontroller running at 80 MHz, integrating 256 KB of Flash program memory and 32 KB of SRAM in a 121-ball TFBGA (10x10 mm) package. It belongs to the PIC32MX3xx/4xx general-purpose family with CAN and USB 2.0 Full-Speed On-The-Go peripherals, making it suitable for connected embedded designs requiring both industrial networking and device-host USB roles. A microcontroller (MCU) is an integrated circuit that combines a CPU core, volatile and non-volatile memory, and programmable peripherals on a single die. The PIC32MX3xx family belongs to the higher-level taxonomy: 32-bit MCU -> embedded microcontroller -> RISC processor -> integrated circuit -> semiconductor. The MIPS32 M4K core executes most instructions in a single cycle, providing deterministic performance for real-time control loops and signal-processing tasks that 8-bit or 16-bit MCUs cannot handle within the same power budget. Key features of the PIC32MX360F256L-80I/BG include a 10-bit 1 Msps ADC with up to 16 channels, five 16-bit timers/counters, two I2C, two SPI, and two UART interfaces, plus dedicated CAN and USB OTG controllers. The 121-TFBGA package provides 85 general-purpose I/O pins, the highest pin count in the PIC32MX3xx family, enabling complex designs that need parallel buses, multiple UART bridges, and large pin-count glue logic on a single die. The internal 8 MHz Fast RC oscillator with PLL delivers the 80 MHz system clock without an external crystal, simplifying BOM. Typical applications include industrial control panels, USB peripherals (HID, CDC, mass storage), CAN-based automotive body controllers, multi-channel data loggers, and graphical user-interface boards. The wide -40C to +85C industrial temperature range and 2.3V-3.6V operating voltage suit battery-powered and industrial 3.3V rails alike. The 80 MHz core plus DMA controller supports small embedded TCP/IP stacks and USB audio class implementations without an external PHY. When designing with this MCU, ensure the USB VBUS pin has a 5V-tolerant protection scheme and the CAN bus uses a proper transceiver (e.g., MCP2551). The 121-ball BGA requires 0.8 mm pitch routing with via-in-pad or laser-drilled microvias; PCB manufacturing cost is higher than QFP equivalents. Decouple each VDD/AVDD pair with 100 nF plus 4.7 uF bulk capacitors placed within 5 mm of the balls.
