The Microchip Technology PIC32MX450F128LT-I/PT is a 32-bit MIPS32 M4K PIC microcontroller running at 80 MHz with 128 KB of Flash program memory and a 100-pin TQFP (12x12 mm) package, built on the PIC32MX3/4 family platform. This single-core MCU delivers up to 100 DMIPS of computational performance while integrating 2 SPI/I2S, 2 I2C, 2 analog comparators, USB 2.0 full-speed, and a 28-channel 10-bit ADC on-chip, eliminating external peripheral ICs. A microcontroller (MCU) is a single-chip computer that combines a CPU core, program and data memory, and configurable I/O peripherals. The PIC32MX family uses the MIPS32 M4K core, a 32-bit RISC architecture from Imagination Technologies that Microchip licenses - making PIC32MX a 32-bit performance step above the 8-bit PIC16/PIC18 and 16-bit PIC24 families, while sharing Microchip's MPLAB X IDE and Harmony framework ecosystem. Within the power management and embedded control hierarchy, PIC32MX MCUs sit between Cortex-M0/M0+ microcontrollers and Cortex-M3/M4 parts in both performance and cost. Key features include 80 MHz core clock (up to 100 MHz in some family variants), 128 KB single-cycle Flash with live update support, 32 KB SRAM, 2 SPI/I2S ports, 2 I2C ports, 2 UART ports, a USB 2.0 full-speed device/host/OTG controller, 5 16-bit timers/counters, and a 28-channel 10-bit 1 Msps ADC. The wide 2.3V to 3.6V supply range simplifies single-rail designs from 3.3V lithium or USB-fed power trees. Architecturally, the PIC32MX450 uses a 5-stage MIPS pipeline with hardware multiply/divide, single-cycle Flash read through a 128-bit wide prefetch buffer, and a dedicated DMA controller for peripheral-to-memory transfers without CPU intervention. The 80 MHz part variant is a power-optimized speed grade of the 100 MHz PIC32MX450 family, ideal for cost-sensitive applications that do not need maximum throughput. Typical applications include USB peripherals (HID, CDC, mass storage), IoT edge nodes with TCP/IP stacks, industrial sensor hubs, consumer appliances with capacitive touch via the Peripheral Pin Select (PPS) feature, and 32-bit upgrade paths for legacy PIC24 or PIC32MX1/2 designs. The 100-pin TQFP package offers 78 usable I/O pins plus USB transceiver pins, sufficing for human-machine interface (HMI) panels and small graphics. When designing with this device, leave a 1 MOhm pull-up on the TMS pin for reliable 4-wire JTAG operation, and follow Microchip's Section 2.0 "Guidelines for Getting Started with 32-bit MCUs" - especially the 10 uF bulk + 0.1 uF decoupling arrangement within 6 mm of each VDD/VSS pin pair to keep the ADC noise floor low. The PT suffix designates the 100-pin TQFP package. This page synthesizes distributor pricing, drop-in PIC32MX alternatives, and practical design notes not found in a single datasheet chapter.

The MIPS32 M4K core executes most instructions in a single cycle and includes a hardware multiply/divide unit, achieving up to 1.56 DMIPS/MHz. The architecture combines Harvard bus organization with separate instruction and data paths, plus a prefetch cache to mitigate Flash wait states at full 80 MHz. Code protection, JTAG and two-wire programming/debug interfaces support field updates. The 124-pin VTLA EP package exposes ample I/O for parallel buses, multiple serial channels, and external memory interfaces. Typical applications include USB peripherals (HID, CDC, mass storage), industrial control and HMI panels, audio processing with I2S codec interfaces, multi-channel sensor data acquisition, and consumer devices requiring USB connectivity. The integrated USB 2.0 FS OTG controller eliminates the need for an external PHY in low-cost designs. A key design consideration is decoupling: place 0.1 uF and 10 uF capacitors close to each power pin pair, and reserve the VBUS pin for 5V-tolerant USB operation. For analog accuracy, route the AVDD/VSS pair with a ferrite bead and keep ADC traces away from switching nodes.

It belongs to the PIC32MX3/4 family combining 32-bit performance with integrated USB, two I2S/SPI audio interfaces, IRDA, six DMA channels, and 2 analog comparators. A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory (Flash), working memory (SRAM), and integrated peripherals such as timers, communication controllers and analog blocks. PIC32MX parts sit in Microchip's MIPS-based 32-bit line, between the 8-bit PIC16/PIC18 families and the 64-bit MIPS-class parts, and target cost-sensitive embedded designs that need more headroom than 8-bit cores without moving to ARM Cortex-M. The "M4K" pipeline implements a 5-stage MIPS32 release 2 architecture with hardware multiply/divide and DSP-style multiply-accumulate, so the 120 MHz clock yields 150 DMIPS while consuming as little as ~70 mA active. Key features include two SPI/I2S peripherals for audio or external ADC/DAC streaming, a full-speed USB 2.0 device/host/OTG controller, a 16-channel 10-bit 1 Msps ADC, five 16-bit timers, six UARTs, two I2C modules and an IrDA SIR encoder/decoder. The 64-pin package exposes up to 53 GPIO, the Parallel Master Port (PMP) for graphics or external memory, and CTMU + 5-bit DAC comparators enabling capacitive touch sensing. Architecturally, the part pairs the MIPS M4K core with a 32 KB instruction cache (prefetched from Flash) and a separate 4 KB RAM cache, which together explain why the 120 MHz core can approach 150 DMIPS despite Flash access times that would otherwise bottleneck execution - the cache pre-loads instructions ahead of demand. Typical applications include USB audio bridges, HMI panels using PMP-driven LCDs, low-cost digital photo frames, industrial control with CAN-bridge via SPI, motor control with PWM, and USB-CDC class devices. The combination of USB, I2S, and CTMU in a 64-pin TQFP suits compact consumer and industrial hardware. When designing, ensure VDD/VSS pairs have 0.1 uF ceramic bypass within 5 mm of every supply pin, and provision a 4.7-10 uF bulk cap at the regulator output. Program Flash endurance is rated for a minimum of 1,000 erase/write cycles per sector - reserve EEPROM emulation or wear-leveling if your firmware updates frequently. This page combines distributor pricing, parametric comparison and drop-in alternative guidance from Microchip's PIC32MX family, plus design notes compiled from the manufacturer datasheet and reference designs.

It is a member of the PIC32MX3/4 family, which combines 32-bit performance, USB 2.0 full-speed On-The-Go support, and a rich peripheral set targeted at low-cost embedded designs. What is a 32-bit microcontroller? A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory (Flash), working memory (RAM), and integrated peripherals such as timers, communication controllers, and analog blocks. The PIC32MX450F256L belongs to the 32-bit class, meaning its data path, registers, and arithmetic units are 32 bits wide - enabling higher code density, faster arithmetic, and larger addressable memory than 8-bit or 16-bit MCUs. Within Microchip's portfolio it sits in the PIC32MX family, which uses the MIPS32 M4K core and targets cost-sensitive embedded applications. Key features of the PIC32MX450F256LT-I/TL include two SPI/I2S ports, two I2C ports, two UART/USART blocks, two analog comparators, a 10-bit ADC with up to 28 input channels, a Parallel Master Port (PMP), and a USB OTG full-speed transceiver. The MIPS M4K core delivers 1.56 DMIPS/MHz, giving roughly 125 DMIPS at the 80 MHz maximum operating frequency. Hardware multipliers, a prefetch cache, and a dedicated DMA controller support deterministic real-time response. The architecture combines a Harvard-style bus with up to 32 KB of prefetch cache and tightly coupled SRAM, allowing zero-wait-state execution from Flash at full speed. The integrated USB OTG controller with on-chip transceiver eliminates the need for an external PHY for full-speed device or host applications. The on-chip voltage regulator generates the 1.8V core voltage from a single 2.3-3.6V supply, simplifying board design. Typical applications include consumer USB peripherals, human-interface devices (HID) such as keyboards and game controllers, industrial HMI panels, low-cost motor control, and embedded Wi-Fi/Bluetooth co-processor hosts. The combination of 256 KB Flash and 64 KB RAM supports USB stacks, TCP/IP libraries, and graphical user interfaces built on the MPLAB Harmony framework. When designing with this part, ensure that the USB pins are routed as a 90-ohm differential pair (D+/D-) and that the VDDCORE pin has a 1 uF low-ESR ceramic capacitor placed within 4 mm. Always use the latest MPLAB X IDE with the matching XC32 compiler to guarantee correct SFR definitions, and review the device errata published by Microchip before locking the BOM.

A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and a rich set of peripherals onto one die. Within the product taxonomy, a microcontroller falls under integrated circuits -> microcontrollers -> 32-bit microcontrollers, and PIC32MX parts specifically target cost-sensitive embedded applications that need 32-bit throughput but can be served by the legacy MIPS M4K core rather than a modern Cortex-M class core. Key differentiating features include 256 KB Flash and 64 KB SRAM, 80 MHz operation with 100 DMIPS throughput, USB 2.0 full-speed On-The-Go (OTG) support, and 5V-tolerant I/O for industrial signaling levels. The CTMU enables touch and capacitive sensing, while the RTCC supports battery-backed timekeeping. Compared to lower-end PIC32MX1/2 devices, the PIC32MX4 adds parallel master port and a higher pin-count package suitable for parallel bus interfaces. Architecturally, the PIC32MX450F256L uses the MIPS32 M4K core with 5-stage pipeline, single-cycle multiply and hardware divide, plus a 7-bit prefetch buffer that boosts Flash throughput. The 100 MHz / 80 MHz bus matrix keeps DMA and CPU accesses non-blocking, which is critical when USB, ADC and SPI/I2S operate concurrently. The 256 KB Flash is partitioned for self-programming and bootloader use cases. Typical applications include USB peripherals, industrial control panels, graphical user interfaces with parallel LCD, capacitive touch human-machine interfaces, motor control (via PWM and comparators), and point-of-sale terminals. The wide I/O count supports external memory buses and multiple serial channels simultaneously. When designing with the PIC32MX450F256LT-V/PF, ensure the 80 MHz operating frequency and 2.5-3.6 V supply range are respected, and use a 4-layer PCB with a solid ground plane for the 100-pin TQFP thermal pad. For migration paths, the PIC32MX450F256L family offers other pin-count and temperature grade options sharing the same die.
