It supports 2.5V/3.3V operation, includes USB OTG, two I2S, four SPI, I2C, UART, PMP, and a 10-bit ADC with CTMU for touch sensing. A 32-bit microcontroller (MCU) is an integrated circuit containing a processor core, program memory (Flash), data memory (SRAM), and configurable peripherals on a single die. PIC32MX230F devices belong to the PIC32MX1xx/2xx general-purpose family (MIPS32 M4K core) within the broader PIC32 microcontroller portfolio, which targets USB, graphics, and HMI applications with integrated connectivity and analog peripherals. Key features include 128KB Flash (128K x 8), 16KB SRAM, Peripheral Pin Select (PPS) for flexible signal routing, Parallel Master Port (PMP) with dual buffers for graphics, hardware crypto engine (in select variants), 5 PWM channels, and a 16-channel 10-bit ADC. Industrial-grade -40C to +105C temperature range (V-suffix) ensures operation in harsh environments. The MIPS32 M4K core executes most instructions in one cycle, delivering up to 1.56 DMIPS/MHz (83 DMIPS at 50MHz). The 5-stage pipeline and hardware multiply/divide accelerator enable deterministic real-time performance. PPS allows remapping of digital peripherals to most I/O pins, simplifying PCB layout and BOM reuse across family variants. Typical applications include industrial control and HMI panels, USB device/host peripherals, audio playback with I2S codecs, low-cost graphics interfaces (PMP), sensor hubs with CTMU touch, and consumer appliances requiring USB connectivity. The integrated USB OTG full-speed controller eliminates external PHY chips. When designing with this device, ensure the 64-pin QFN EP has sufficient PCB copper pour (minimum 1 sq inch) to dissipate heat and provide a low-impedance ground. Decouple VDD/VSS pairs with 100nF + 1uF ceramics placed within 3mm of each pin pair. Configure PPS before enabling peripherals to avoid spurious signals.

It belongs to the PIC32MX2xx family, the cost-optimized general-purpose segment of the PIC32MX portfolio, designed for embedded HMI, audio, and connectivity applications. A 32-bit microcontroller (MCU) is an integrated circuit that combines a 32-bit processor core, program and data memory, and a rich set of peripherals on a single silicon die. Within the broader semiconductor taxonomy, an MCU sits below microprocessors in integration but above standard logic ICs in computational capability, occupying the embedded-computing tier. The PIC32MX230F128L belongs to the PIC32 family (Microchip), positioned as a high-performance extension of the legacy PIC16/PIC24 dSPIC families, and runs the MIPS32 instruction set. Key differentiating features of this part include two I2S modules for digital audio, four SPI interfaces for codec and serial communications, a Parallel Master Port (PMP) with dual read/write buffers for graphics interfaces, Peripheral Pin Select (PPS) for flexible I/O mapping, and a 10-bit ADC with up to 1 Msps conversion rate. The 128 KB Flash supports self-programming, while 16 KB SRAM provides generous headroom for data buffers in audio and graphics workloads. Architecturally, the PIC32MX230F128L uses a 5-stage pipeline MIPS32 M4K core with single-cycle multiply, hardware divide, and a tightly-coupled prefetch buffer that hides Flash latency. The bus matrix supports concurrent DMA transfers between peripherals and memory, enabling efficient streaming of audio samples to I2S without CPU intervention. PPS allows most digital peripherals to be remapped to nearly any digital I/O pin. Typical applications include consumer audio devices (MP3 players, Bluetooth speakers, headphone amplifiers with DSP), HMI control panels with small TFT displays, low-cost CAN-connected industrial sensors, USB device peripherals, and general-purpose embedded control with 32-bit performance headroom. When designing with this part, note that the 50 MHz maximum clock rate is a -50I industrial-grade part rated -40C to +85C; for automotive applications choose the -V variant, and for extended temperature choose the -E variant. Verify PPS remapping on every design revision because peripheral-to-pin mappings vary across PIC32MX sub-families.

The Microchip PIC32MX230F128LT-50I/PT is a 32-bit MIPS microcontroller from the PIC32MX2xx family, featuring a MIPS32 M4K core running at 50 MHz, 128 KB of Flash program memory, and 16 KB of SRAM, housed in a 100-pin TQFP (12x12 mm) package. It operates from 2.3 V to 3.6 V and integrates USB 2.0 full-speed, I2C, SPI, UART, PMP, and 10-bit ADC peripherals for mixed-signal embedded designs. What is a PIC32MX microcontroller? The PIC32MX is Microchip's line of 32-bit MIPS-based microcontrollers, extending the classic PIC architecture into the 32-bit domain. Architecturally, a PIC32MX sits in the hierarchy: MCU -> 32-bit MCU -> MIPS-based MCU -> PIC32MX -> PIC32MX2xx family. It combines the deterministic behavior and ease of use that PIC MCUs are known for, with the throughput and memory headroom of a 32-bit core, enabling connectivity, USB, and graphical user-interface workloads that 8-bit or 16-bit parts cannot comfortably handle. Key features include a single-cycle 32-bit multiply-divide unit, DMA controller for peripheral data movement without CPU intervention, and an 80 MHz maximum operating frequency (50 MHz at the device's worst-case commercial/industrial ratings). The integrated USB 2.0 full-speed OTG controller, parallel master port (PMP), and CTMU touch peripheral expand the device beyond traditional GPIO-and-UART designs. 16 KB of SRAM and 128 KB of self-programmable Flash give enough room for USB stacks, TCP/IP, or modest graphics libraries. The PIC32MX230F128L integrates a high-performance MIPS M4K core with Harvard bus architecture, achieving 1.56 DMIPS/MHz, paired with a fast interrupt controller that supports up to five external interrupts and an 8-level deep hardware stack. The peripheral set is pin-mapped and clocked through configurable dividers, with the DMA controller able to service UART, SPI, and ADC concurrently. Code execution is from internal Flash with optional cache, and JTAG/ICSP/4-wire programming interfaces are supported for production-line firmware load. Typical applications include USB peripherals such as HID human-interface devices, industrial control nodes requiring serial connectivity (UART, I2C, SPI) and PMP-driven displays, low-cost graphics-enabled HMIs using PMP-to-LCD or OLED panels, sensor hubs with CTMU-based capacitive touch, and connectivity bridges that pair USB with UART/SPI peripherals. The industrial temperature grade (-40C to +85C) and 3.3 V I/O make it compatible with mainstream CMOS peripherals. Design consideration: when porting a PIC24/dsPIC design to PIC32MX, verify stack depth and vector table layout - PIC32MX uses a MIPS-style exception model. Decoupling must include a 100 nF plus 10 uF bulk near VDD/VSS pins, and the USB D+/D- lines need 15 kΩ pull-down resistors per the USB specification when configured as a device. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, giving engineers and buyers a single, citable reference for the PIC32MX230F128LT-50I/PT.

PIC32MX230F256B-50I/SP

PIC32MX230F256B-50I/SP - 32-bit 50MHz 256KB Flash MCU | Microchip

The Microchip PIC32MX230F256B-50I/SP is a 32-bit MIPS32 M4K microcontroller running up to 50 MHz / 83 DMIPS, integrating 256 KB of Flash and 16 KB of SRAM on-chip, housed in a 28-pin SPDIP (SP) through-hole package with industrial -40C to +85C temperature rating. A 32-bit microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, data memory, and a rich set of peripherals on one silicon die. The PIC32MX family combines a MIPS32 RISC architecture with Microchip's peripheral ecosystem, targeting general-purpose embedded applications where 8-bit MCUs run out of headroom but full application processors are over-spec. PIC32MX230F256B variants sit at the low-power, USB-capable node of the family with up to 256 KB Flash and 64 KB SRAM across the wider PIC32MX230/250/270/280 series. Key features of the PIC32MX230F256B-50I/SP include two I2S/SPI modules for codec and serial communications, Peripheral Pin Select (PPS) remappable I/O, Parallel Master Port (PMP) for graphics interfaces, mTouch capacitive touch support, and high-resolution 1 ns time measurement. An on-chip temperature sensor, RTCC, CTMU, and 10-bit ADC round out the analog/mixed-signal integration. The MIPS32 M4K core provides 5-stage pipeline execution with single-cycle multiplication, while 0.5 mA/MHz typical run current keeps active power low for USB-enabled designs. The architecture pairs the 32-bit MIPS core with a 7-bit peripheral bus and dedicated DMA, allowing deterministic I/O servicing alongside CPU-bound DSP-style code. The 256 KB Flash supports live update partitioning and the 16 KB SRAM enables stack-heavy RTOS or TCP/IP stacks (Microchip's Harmony TCP/IP lite) without external memory. USB 2.0 full-speed OTG is integrated on the die, removing external PHY cost for HID, CDC, or vendor-class peripherals. Typical applications include USB peripherals (HID keyboards, CDC serial bridges, vendor-class instrumentation), capacitive-touch user interfaces for appliances and HVAC controls, low-cost graphics with PMP-driven LCDs, sensor hubs with mTouch, and industrial control nodes requiring RTCC plus analog.

Prefetch cache and a separate instruction/data Flash branch predictor help mitigate the Flash wait-state penalty, enabling near-50 MHz zero-wait-state execution from on-chip memory. Typical applications include USB HID/CDC peripherals, low-cost graphics HMI with PMP-driven LCDs, capacitive-touch user interfaces, audio playback via I2S codecs, and industrial sensor hubs. The combination of USB-OTG, PMP, and mTouch in a QFN-44 makes it well suited to compact appliances and consumer electronics. When designing with this part, pay attention to USB board layout (90-ohm differential, controlled impedance), decoupling (100 nF + 4.7 uF near each VDD pin), and PPS reconfiguration - peripherals are mapped to pins via software after reset, so default pin assignments in the I/O map will not apply. Leave the RTCC clock domain properly decoupled when using backup-battery mode.

PIC32MX230F256DT-50I/ML

PIC32MX230F256DT-50I/ML - 50MHz 256KB Flash MCU | Microchip 44-QFN

The Microchip Technology PIC32MX230F256DT-50I/ML is a 32-bit MIPS32 M4K microcontroller running at 50 MHz, integrating 256 KB of Flash and 16 KB of SRAM in a 44-pin QFN (8x8 mm) package with industrial-grade -40C to +85C operation. Per the PIC32MX1XX/2XX 28/36/44-pin family datasheet, it delivers 83 DMIPS of computational throughput while drawing only 0.5 mA/MHz typical, making it one of the most power-efficient PIC32MX parts available. A 32-bit microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and a rich set of peripherals into one package. In the taxonomy hierarchy, MCU belongs to the broader integrated-circuit family, sitting below microprocessors (which need external memory) and above simple 8-bit controllers. The 32-bit class specifically targets applications where arithmetic performance, addressable memory, and peripheral integration outweigh the lower unit cost of 8/16-bit alternatives. The PIC32MX230F256DT series occupies the low-power, USB-capable mid-range of this 32-bit MCU landscape. Key features include a 10-bit 1.1 Msps Analog-to-Digital Converter (ADC) with up to 28 channels, a USB 2.0 full-speed Device/Host/OTG controller, two I2S/SP I modules for audio codec connectivity, Peripheral Pin Select (PPS) for flexible I/O mapping, a Parallel Master Port (PMP) for graphics or external memory interfaces, an mTouch capacitive-touch sensing peripheral, and a 1 ns high-resolution 16-bit timer for precise time measurement. The integrated 80 MHz FRC and 32 kHz secondary oscillator reduce external BOM cost. Technically, the M4K core implements the MIPS32 release 2 instruction set with single-cycle hardware multiply/divide, branch shadowing, and a tightly-coupled prefetch buffer that masks Flash latency. The 256 KB Flash is partitioned with a 32 KB boot Flash block for fail-safe firmware updates, and 16 KB SRAM supports DMA transfers without CPU intervention. The device supports 3.3V single-supply operation across 2.3V to 3.6V, with on-chip LDO generating core voltage from VDD. Typical applications include USB HID peripherals (mice, keyboards, custom HID class devices), low-cost audio accessories using external I2S codecs, capacitive-touch user interfaces for appliances, and small TFT graphic displays driven via PMP. The combination of USB, I2S, and graphics-capable PMP in a small 44-QFN footprint is the defining use-case envelope. Design consideration: route the USB DP/DM lines as a 90 ohm differential pair with no stubs, and place the 48 MHz crystal within 5 mm of the OSCI/OSCO pins to meet USB jitter requirements. The exposed thermal pad on the QFN package MUST be soldered to a ground plane of at least 1 sq inch for thermal and electrical performance.

PIC32MX230F256DT-50I/PT

PIC32MX230F256DT-50I/PT - 50MHz 32-bit MCU 256KB Flash USB | Microchip

The Microchip PIC32MX230F256DT-50I/PT is a 32-bit MIPS MCU from the PIC32MX2xx family, delivering up to 50 MHz (83 DMIPS) of processing throughput while integrating 256 KB of Flash, 16 KB of SRAM, and a full-speed USB 2.0 device/host/OTG controller in a 44-pin TQFP package (10x10 mm). A 32-bit microcontroller is an integrated computing subsystem built around a wide datapath CPU core, on-chip Flash for program storage, on-chip SRAM for runtime data, and a rich set of peripherals including ADCs, timers, communication controllers, and I/O ports. Within the broader silicon taxonomy, this PIC32MX part belongs to the microcontroller (MCU) class, which itself is a subcategory of microprocessors and embedded computing devices, ultimately falling under semiconductors. Compared with 8-bit and 16-bit MCUs, 32-bit parts execute instructions faster and handle wider data types, which simplifies protocols such as USB, TCP/IP stacks, and digital signal buffering. Key differentiating specifications of this part include the MIPS32 M4K core with single-cycle multiplication, hardware PMP (Parallel Master Port) for graphics interfaces, Peripheral Pin Select (PPS) for flexible signal routing, three analog comparators with a programmable reference, a 10-bit ADC with up to 1 Msps conversion rate, an on-chip RTCC calendar with 1 ns time-measurement resolution, and CTMU support for mTouch capacitive touch buttons and sliders. The integrated USB 2.0 full-speed transceiver eliminates the need for an external PHY, and the 50 MHz operating frequency keeps instruction execution below 40 mA typical active current at 3.3 V. The architecture combines the Harvard-style M4K core with five 32-bit timer/counters, two I2S/SPI modules for codec and serial communication, and dual analog comparators, supporting low-power sleep and idle modes. The USB peripheral handles device, host, and On-The-Go roles directly, while the PMP enables direct bus-mastered interface to external parallel memory or graphical displays. Typical applications include USB peripherals (HID, CDC, MSD), capacitive touch human-machine interfaces (HMIs) using CTMU, low-cost graphical displays driven via PMP, sensor conditioning front ends, and industrial control nodes. The wide operating range (-40 C to +85 C industrial grade) and 2.3 V to 3.6 V VDD tolerance suit battery-powered and industrial environments. A critical design consideration is the VDD/VUSB decoupling network: place a 0.1 uF ceramic cap adjacent to every VDD pin and a 1 uF to 10 uF bulk capacitor on the USB VBUS rail to meet USB 2.0 full-speed signaling integrity. Use the PPS feature to remap peripherals only after enabling the corresponding IOLOCK bit, otherwise the mapping is lost on reset.

It belongs to the PIC32MX1/2/5 general-purpose family and is qualified for the industrial -40C to +85C operating range with a 2.3V to 3.6V supply rail. A PIC32MX microcontroller is a 32-bit RISC MCU built on the MIPS microAptiv/M4K core that combines the simplicity of the legacy PIC16/PIC18 toolchain with the throughput and address space of a 32-bit core. Within the broader semiconductor taxonomy, it sits in the hierarchy: microcontroller (MCU) -> 32-bit MCU -> MIPS32 MCU -> PIC32MX family. The architecture includes a 5-stage pipeline, hardware multiply/divide, single-cycle 32-bit ALU, and tightly-coupled peripherals tuned for USB, motor control, and graphical user interface (WQVGA) applications. Key differentiating features include hardware USB 2.0 full-speed device/host/OTG, a 10-bit 1 Msps analog-to-digital converter with up to 28 channels, four general-purpose 16-bit timers/capture/compare, two UART, two SPI, two I2C, PMP (Parallel Master Port) for graphics, CTMU (Charge Time Measurement Unit) for touch and capacitive sensing, and a 4-channel DMA controller. The 256 KB flash supports self-programming and the device includes a configurable interrupt controller with 5 priority levels. The device operates from a single 2.3V to 3.6V supply, supports 5V-tolerant inputs (when configured), and features low-power Sleep, Idle, and Deep-Sleep modes with sub-microamp wake-up currents. The QFN-44 (8x8 mm) package with exposed thermal pad provides efficient heat dissipation for industrial designs where board space is constrained. Typical applications include USB peripherals (HID, CDC, MSD), industrial control and sensing nodes, low-cost graphical HMI displays, capacitive touch user interfaces, motor control reference designs, and consumer appliances with USB connectivity. Its combination of USB, graphics, and touch peripherals also suits POS terminals, medical data acquisition front ends, and building automation controllers. When designing with this part, note that firmware is developed under MPLAB X IDE with the XC32 compiler. The 16 KB SRAM is shared between data and DMA buffers, so USB + graphics stacks benefit from a careful memory map. Decoupling requires at minimum a 100 nF ceramic near each VDD/VSS pair plus a bulk 4.7 uF at the regulator output.
