PIC32MX340F512HT-80I/MR 개요
A 32-bit microcontroller (MCU) is an embedded computing device built around a 32-bit datapath, registers and bus architecture, allowing it to process larger data words in a single instruction compared with 8-bit or 16-bit MCUs. Within the broader semiconductor taxonomy, the PIC32MX3XX/4XX family sits in the high-performance general-purpose tier, above 8-bit PICmicro and 16-bit PIC24/dsPIC devices, and below specialized 32-bit application processors. The PIC32MX340F512HT specifically targets USB-enabled, high-throughput embedded designs that also need fast interrupt response.
Key differentiating features include 53 general-purpose I/O pins, a 10-bit ADC, USB 2.0 Full-Speed On-The-Go (OTG) controller, four 16-bit timers, two UART/SPI/I2C peripherals, a Parallel Master Port (PMP) for external memory or graphics, and a CTMU for capacitive touch sensing. The 64-pin VQFN (MR) footprint exposes the full peripheral set while keeping the PCB land area to 9x9 mm, making the part attractive for space-constrained industrial control and USB device designs.
Architecturally, the M4K core executes most instructions in one cycle and supports compact MIPS16e mode, which can reduce code size by up to 40 percent. The 256 KB user Flash plus 12 KB boot Flash, executed from RAM, allows field firmware upgrades, while the 4-channel DMA offloads data movement from the core to peripherals such as the ADC and USB.
Typical applications include USB peripherals (HID, CDC, mass storage), industrial control panels, embedded data loggers, and home-automation gateways. Designers should review the I/O count and 64-VQFN footprint against the alternate PIC32MX340F512H-80I/PT (64-pin TQFP) when thermal dissipation or hand-prototyping is required.

일반적인 애플리케이션
PIC32MX340F512HT-80I/MR 적합 용도: 6 애플리케이션s: USB HID and CDC Peripherals, Industrial Control Panels, Embedded Data Loggers, Home-Automation Gateways, Medical Point-of-Care Devices, USB-Connected Sensor Hubs.
USB HID and CDC Peripherals
The PIC32MX340F512HT's USB 2.0 Full-Speed OTG controller with on-chip transceiver makes it a strong fit for HID, CDC (virtual COM), mass-storage and vendor-class USB peripherals. The 80 MHz M4K core plus 4-channel DMA sustains USB endpoint throughput without CPU stalls, while the 512 KB Flash supports composite USB stacks with HID+CDC or HID+MSD combinations. The 64-VQFN footprint exposes all 53 GPIO so designers can keep the USB connector plus user I/O on the same PCB.
추천
Industrial Control Panels
At -40 to +85 C industrial range with 53 GPIO and a 10-bit ADC, the PIC32MX340F512HT fits industrial control panels that need to drive relays, read sensors and exchange data over UART or RS-485. The 32 KB SRAM supports Modbus RTU buffers, while the 4-channel DMA offloads ADC scan sequences for real-time closed-loop control. The 64-VQFN footprint survives standard industrial shock/vibration profiles when the land pad is reinforced per Microchip AN232.
추천
Embedded Data Loggers
With 512 KB Flash and 32 KB SRAM, the PIC32MX340F512HT serves as the controller of SD-card or external-Flash-based data loggers capturing ADC, I2C and SPI sensor data. The 4-channel DMA streams serial peripherals into SRAM without CPU intervention, and execute-from-RAM mode allows deterministic logging routines at 80 MHz even when the Flash wait states are active. The 10-bit ADC is sufficient for battery-cell voltage and temperature monitoring in energy-storage data loggers.
추천
Home-Automation Gateways
The PIC32MX340F512HT is well-suited as a Wi-Fi/Ethernet-bridge gateway between low-power microcontrollers and a cloud service over USB or UART. Its 32 KB SRAM accommodates TLS-1.2 handshake scratch buffers when paired with a Wi-Fi module such as the Microchip WINC1510, and the USB OTG controller enables local USB device enumeration. The 64-VQFN (9x9 mm) keeps the gateway PCB smaller than 30x40 mm for in-wall mounting.
추천
Medical Point-of-Care Devices
The PIC32MX340F512HT powers handheld medical devices such as glucose meters, pulse oximeters and portable spirometers, where deterministic USB data transfer to a host PC and low-power modes are both required. The PIC32MX3XX/4XX family supports sleep currents below 50 uA in deep-sleep mode, helping meet IEC 60601-1 battery-budget requirements, while the 80 MHz core executes DSP-style SpO2 or ECG signal-processing kernels. The 64-pin VQFN footprint fits handheld enclosures under 15x8x3 cm.
추천
USB-Connected Sensor Hubs
USB-Connected Sensor Hubs aggregate I2C, SPI and analog inputs and stream them to a host PC; the PIC32MX340F512HT combines USB OTG, 53 GPIO and a 10-bit ADC for this role. The 4-channel DMA streams I2C/SPI sensor traffic into SRAM while the USB endpoint simultaneously sends the buffer to the host. The 64-VQFN land pattern keeps hub boards under 25x25 mm so multiple hubs can stack on a DIN rail.

설계 노트
Power PIC32MX340F512HT from a 3.3 V LDO with at least 200 mA peak capacity (80 MHz core can draw 60-80 mA active). The USB transceiver rail (VUSB3V3) must be sourced separately - per Microchip AN592 - and the VBUS pin requires a 5 V tolerant input divider. Estimated: at 80 MHz active + USB enumeration, the part consumes approximately 70 mA; add a 100 nF + 10 uF decoupling pair close to each VDD/AVDD pin pair. [DATA_NEEDED: exact ICC vs MIPS curve from datasheet].
The 64-pin VQFN (9x9 mm) land pattern has a 0.50 mm pitch and requires a centre thermal pad that MUST be soldered to a continuous copper pour to meet the thermal datasheet spec (theta_JA approximately 30 C/W). Per Microchip AN232, route four or more vias through the centre pad to an internal ground plane. Without the centre pad solder connection, the junction can rise 20-30 C above the rated profile.
Do not confuse the 'T' suffix (Tape and Reel) with a temperature grade - the I grade temperature is part of the -80I/MR suffix, not the T suffix. Also, MPLAB Harmony projects targeting the PIC32MX340F512HT must enable the FS USB stack with the on-chip transceiver (not the external PIC32MX3XX/4XX ULPI variant) and the correct PLL settings (FPLL = 8 MHz * 20 = 160 MHz, SYSCLK = FPLL/2 = 80 MHz). Forgetting the PLL divider produces an unstable core.
Place the 12 MHz or 8 MHz crystal within 5 mm of the OSC1/OSC2 pins with a guarded GND ring to avoid coupling USB noise into the PLL reference. Keep the USB D+/D- traces matched to within 150 mil length and maintain 90 ohm differential impedance per USB 2.0 spec. Route the ICSP PGECx/PGEDx pair as a length-matched differential to keep programming reliable at high temperature.
The 10-bit ADC inside the PIC32MX340F512HT achieves full 10 ENOB only with a clean AVDD rail. Decouple AVDD and AVSS with a 10 uF + 100 nF pair placed within 5 mm of the pin pair and add a ferrite bead between VDD and AVDD to suppress digital switching noise. Estimated: ADC noise floor improves from approximately 2 LSB rms to 1 LSB rms with proper AVDD isolation. [DATA_NEEDED: exact AVDD noise rejection figure from datasheet].
