The Microchip Technology PIC32MX230F128L-50I/PF is a 32-bit MIPS microcontroller based on the MIPS32 M4K core, operating at up to 50 MHz / 83 DMIPS, with 128 KB of Flash program memory and 16 KB of SRAM, housed in a 100-pin TQFP (14x14 mm) package. 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.

These features give designers flexibility similar to higher-tier Cortex-M0+ MCUs while keeping the Microchip MPLAB X toolchain. Typical applications include industrial control boards, USB device peripherals, HMI touch panels, audio playback with I2S DAC, sensor hubs, and general-purpose embedded designs. Drop-in variants in the same 100-pin TQFP exist with different Flash/RAM densities (PIC32MX230F064, PIC32MX150F256, PIC32MX170F512) for upward/downward memory migration without PCB rework. When designing, ensure decoupling capacitors are placed as close as possible to each power pin (100 nF X7R per pin, plus a bulk 4.7 uF on VDD). Configure PPS carefully - unused remapped pins default to general I/O. A 12 MHz external crystal or internal 8 MHz FRC with PLL is typically used to reach 50 MHz core clock.

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.

The 0.5 mA/MHz typical active current consumption makes it suitable for battery-powered designs. Per Microchip product page, it also provides on-chip temperature measurement capability and supports the MPLAB Harmony and MPLAB X IDE development ecosystem. The PIC32MX1xx/2xx family uses a 5-stage pipeline Harvard architecture with hardware multiply/divide and a configurable instruction cache for deterministic real-time performance. The 28-QFN package is the smallest outline option, suitable for space-constrained PCB designs where thermal performance is acceptable and reflow profile matches JEDEC J-STD-020. Typical applications include consumer electronics with graphical LCDs, capacitive touch user interfaces, low-cost USB peripherals, IoT sensor nodes, and industrial control front-ends. The PMP peripheral can drive external graphics controllers or FPGA memory buses directly. The mTouch library and CTMU hardware enable robust touch button and slider implementations on standard PCB pads. When designing with this MCU, reserve adequate decoupling (100 nF per power pin plus bulk) and follow Microchip's QFN land pattern recommendations for the 6x6 mm ML package. The I-grade operating temperature range is -40C to +85C industrial. Ensure the JTAG/ICD programming interface is accessible for field firmware updates.

PIC32MX230F256B-V/SP

PIC32MX230F256B-V/SP - 32-bit MCU 256KB Flash 40MHz | Microchip

The Microchip Technology PIC32MX230F256B-V/SP is a 32-bit MIPS M4K microcontroller delivering up to 50 MHz / 83 DMIPS performance with 256 KB Flash and 16 KB SRAM, housed in a 28-pin SPDIP (Skinny Plastic DIP, 0.3 inch) through-hole package. The -V (Vdd = 2.0-3.6V) operating-temperature suffix designates an extended industrial temperature range of -40C to +105C, while the /SP suffix identifies the 28-SPDIP package. The device integrates a USB 2.0 Full-Speed peripheral, two I2S/SPI modules, up to four UART channels, two I2C buses, a 10-bit 1 Msps ADC with up to 13 channels, a Charge Time Measurement Unit (CTMU) for capacitive touch, a Parallel Master Port (PMP) for graphics, and Peripheral Pin Select (PPS) that remaps digital peripherals to nearly any I/O pin. What is a PIC32MX230 microcontroller? The PIC32MX230 is the entry-level member of Microchip's PIC32MX1XX/2XX 32-bit MCU family. It is built on the MIPS M4K core with a 5-stage pipeline, Harvard architecture, single-cycle 32x32 hardware multiplier, and a hardware divide unit. The family sits in the broader hierarchy: 32-bit microcontroller -> embedded MCU -> microprocessor -> integrated circuit. Within the PIC32MX family, the PIC32MX230 is positioned below PIC32MX250/270 variants and above the PIC32MX110/120/130/150/170 series, offering USB + CTMU as the headline features. Key features include 256 KB self-programmable Flash with ECC support, 16 KB SRAM, 10-bit 1 Msps ADC, a CTMU for mTouch capacitive touch sensing, integrated Full-Speed USB 2.0 device/host/OTG, PMP for external graphics memory or parallel bus, JTAG and 2-wire ICSP debugging, and on-chip temperature measurement. The PPS feature allows flexible peripheral-to-pin mapping, dramatically simplifying PCB routing and enabling drop-in peripheral reuse across the family. Architecturally, the PIC32MX230 uses a 32-bit MIPS M4K core with single-cycle multiplication, instruction-cache prefetch, and a 2-wire instruction/data bus. The 0.5 mA/MHz typical run current (15 mA at 30 MHz) and 4 deep sleep modes make it suitable for both line-powered and battery-powered designs. Typical applications include USB peripherals (Human Interface Devices, CDC virtual COM ports, mass storage), capacitive touch user interfaces for appliances and consumer products, industrial control with on-chip ADC, low-cost graphical HMI using PMP to drive character LCDs or small TFTs, sensor hub MCUs with on-chip temperature measurement, and audio playback with I2S interfacing to external DACs. When designing with this part, verify your VDD supply falls within the 2.0-3.6V range - this is not a 5V tolerant part. Ensure the Vbus/USB voltage rail current limit is correctly sized if using the integrated USB peripheral. The CTMU requires dedicated firmware configuration to operate as an mTouch slider or button matrix.

PIC32MX230F256BT-50I/SS

PIC32MX230F256BT-50I/SS - 50MHz 32-bit MCU 256KB Flash | Microchip

The Microchip PIC32MX230F256BT-50I/SS is a 32-bit MIPS M4K microcontroller with 256KB Flash, 16KB SRAM, USB 2.0 Full-Speed, and a 50 MHz core clock, housed in a 28-pin SSOP package. It is a member of the PIC32MX1XX/2XX 28/36/44-pin family, combining high-performance 32-bit computing with Microchip's peripheral integration including 10-bit ADC, Comparators, CTMU, and RTCC. Background knowledge: a microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and peripheral interfaces (ADC, timers, communication ports). 32-bit MCUs extend 8/16-bit MCUs with higher computational throughput, larger address spaces, and richer peripheral sets; they sit in the broader taxonomy of microcontrollers -> embedded processors -> semiconductor ICs. The PIC32 family from Microchip uses the MIPS M4K core, providing deterministic performance and a mature toolchain (MPLAB X IDE, XC32 compiler). Key features: 50 MHz core / 83 DMIPS performance, 256 KB Flash program memory with ECC option, 16 KB SRAM data memory, USB 2.0 Full-Speed Device/Host/OTG, up to 21 available I/O pins, 10-bit 1 Msps ADC with up to 13 channels, three analog comparators, CTMU for touch and capacitive sensing, RTCC with calendar mode, and four 16-bit timers. The device supports 2.3V to 3.6V single-supply operation, industrial -40C to +85C temperature range, and is supplied in industrial-grade (-I) and Tape & Reel packaging. Architecture: the MIPS32 M4K core implements the MIPS32 Release 2 instruction set with hardware multiply/divide and a 5-stage pipeline. The PIC32MX2XX integrates 256 KB single-cycle Flash with prefetch cache and 16 KB SRAM with separate bus paths, allowing simultaneous Flash fetch and SRAM access. Peripheral DMA maps directly to RAM, and the bus matrix supports concurrent CPU and DMA traffic without starving either master. The CTMU block provides a constant-current source used for capacitive touch, temperature sensing, and time-of-flight measurements. Typical applications: USB HID peripherals (HID mice/keyboards, CDC virtual COM ports), capacitive touch key panels via CTMU, industrial sensor data acquisition with 10-bit ADC and RTCC timestamping, low-cost graphics and audio playback for embedded UI, and small home-automation controllers. The 28-SSOP footprint targets compact, hand-solder-friendly designs. Design considerations: the 28-pin package limits available I/O; map pin functions carefully against USB D+/D-, oscillator, and ICSP pins. Place a 1uF decoupling cap adjacent to each VDD pin and ensure the USB D+/D- traces are 90 ohm differential and length-matched. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes not found in the standalone manufacturer datasheet, helping engineers shorten BOM validation and qualification cycles.
