PIC32MX320F128LT-80V/PT - 32-bit MCU 128KB Flash 80MHz TQFP-100 | Microchip
MPN: PIC32MX320F128LT-80V/PT ✓ AktifPIC32MX320F128LT-80V/PT Ringkasan
A PIC32MX microcontroller is a 32-bit MCU based on the MIPS32 M4K core from Microchip Technology, combining deterministic real-time response with the rich peripheral set expected of modern embedded designs. It belongs to the larger PIC32 family -> 32-bit microcontroller -> MCU -> embedded processor hierarchy, and sits below higher-tier PIC32MZ and PIC32MK devices in Microchip's portfolio. The 'V' suffix denotes an extended industrial temperature grade of -40C to +105C for harsh-environment use.
Key features of the PIC32MX320F128LT-80V/PT include 128KB Flash organized as 128K x 8, 16KB SRAM, a 10-bit ADC with up to 16 channels, a 16-bit Parallel Master Port (PMP) for external memory or graphics interfaces, USB 2.0 full-speed On-The-Go (OTG), two I2C and two UART/I2S peripherals, two SPI ports, five 16-bit timers/counters, and a 16-channel DMA controller for CPU offload. The MIPS32 M4K core executes most instructions in one cycle and includes a hardware multiply/divide unit for DSP-class operations.
Architecturally the device pairs the MIPS core with Microchip's standard peripheral set, executes code from internal Flash with optional prefetch cache, and supports trace via the standard MIPS trace interface. The integrated 10-bit ADC with up to 500 ksps throughput is adequate for sensor reading and basic instrumentation, while the 5V-tolerant I/O on most pins simplifies connection to legacy 5V logic.
Typical applications include industrial automation controllers, USB device and embedded host products, graphical user interfaces with PMP-driven TFT displays, consumer appliances, motor control interfaces, and low-cost Ethernet or Wi-Fi gateway nodes. The 100-pin TQFP package offers ample I/O (up to 85 GPIO) for parallel buses, making it a popular choice for legacy peripheral migration from PIC24/PIC18 designs.
When designing with this part, ensure the 2.5V/3.3V core supply is decoupled with at least 100 nF + 1 uF close to VDD pins. Take care to configure unused pins as outputs to minimize current draw, and respect the maximum operating temperature of +105C for the 'V' grade. For designs migrating from PIC24/PIC18, the standard MPLAB X IDE and Harmony frameworks provide drop-in peripheral libraries.

Aplikasi Umum
PIC32MX320F128LT-80V/PT cocok untuk 6 aplikasis: Industrial Automation Controllers, USB Device and Embedded Host Products, Graphical User Interfaces with TFT/PMP Displays, Consumer Appliances and Home Devices, Sensor Aggregation and IoT Edge Nodes, Legacy PIC24/PIC18 Migration Designs.
Industrial Automation Controllers
The PIC32MX320F128LT-80V/PT fits industrial automation controllers because its 80 MHz MIPS32 M4K core, 128 KB Flash, and 16 KB SRAM run real-time control loops while its -40 C to +105 C 'V' grade survives unventilated factory cabinets. The 16-channel 10-bit ADC scans sensor inputs at up to 500 ksps and the 16-channel DMA controller offloads repetitive transfers from the CPU. Industrial designers typically pair this MCU with RS-485 transceivers and isolated digital inputs, replacing PLC slices in cost-sensitive sub-100-dollar control nodes.

USB Device and Embedded Host Products
The PIC32MX320F128LT-80V/PT integrates USB 2.0 full-speed On-The-Go, eliminating the need for an external USB controller in mass-storage, HID, CDC, or vendor-class peripherals. With 128 KB Flash and 80 MHz performance it runs the Microchip USB stack alongside an application, and the 16 KB SRAM holds USB descriptors plus application buffers. Typical applications include USB-to-UART bridges, custom HID controls, USB mass-storage devices, and embedded host stacks that read USB flash drives or HID peripherals.

Graphical User Interfaces with TFT/PMP Displays
The PIC32MX320F128LT-80V/PT's 16-bit Parallel Master Port (PMP) drives small TFT panels directly from the 100-pin TQFP without external graphics controllers, while 85 GPIO plus DMA accelerate frame-buffer transfers. At 80 MHz and 16 KB SRAM, it can sustain modest animations on 320x240 QVGA panels using 8-bit or 16-bit parallel interfaces. This suits cost-sensitive GUIs on appliances, instrument front panels, and entry-level HMI screens.

Consumer Appliances and Home Devices
The PIC32MX320F128LT-80V/PT serves consumer appliances and home devices because its 80 MHz MIPS core, 128 KB Flash, USB OTG, and -40 C to +105 C extended grade support smart features like connectivity, touch interfaces, and motor control in washing machines, HVAC controllers, or coffee machines. The integrated 10-bit ADC reads thermistors and pressure sensors, the 5V-tolerant I/O interfaces legacy 5V display panels, and the DMA channels relieve the CPU when running user-interface graphics and communication stacks in parallel.
Direkomendasikan
Sensor Aggregation and IoT Edge Nodes
The PIC32MX320F128LT-80V/PT functions as an IoT edge node aggregating multiple analog and digital sensors, exploiting the 16-channel 10-bit ADC and DMA to sample without CPU intervention. The two UART, two I2C, and two SPI interfaces connect to sensors (temperature, accelerometer, environmental) and radios (Wi-Fi, LoRa, Bluetooth modules). With 128 KB Flash and 80 MHz it can run local filtering and MQTT publish cycles, while the 'V' temperature grade supports outdoor enclosures.

Legacy PIC24/PIC18 Migration Designs
The PIC32MX320F128LT-80V/PT is the most common upgrade path for engineers migrating from 8-bit PIC18 or 16-bit PIC24 designs that have outgrown their original part. The 32-bit MIPS32 M4K core delivers 5-10x the compute per MHz, while the peripheral register map and pinout philosophy closely mirror PIC24, easing firmware ports. The 100-pin TQFP layout matches existing PIC24FJ/PIC24HJ footprints, so PCB redesign is unnecessary - only the firmware, startup code, and interrupt vectors need updating.

Catatan Desain
Decouple VDD/VSS pairs with at least 100 nF (X7R ceramic) and 1 uF (X5R) within 5 mm of each VDD pin; place them on the same layer as the IC to minimize parasitic inductance. The 100-pin TQFP has multiple VDD/VSS pairs distributed around the package for low-impedance power distribution - skip a pair only if your layout is impossible, but ensure every VDD pin has at least one bypass capacitor. The internal USB voltage regulator at VUSB requires a 100 nF + 4.7 uF filter network if USB is used.
The 100-pin TQFP package has a thermal resistance of approximately 65 C/W (theta-JA), so a 1 W power dissipation creates a 65 C junction temperature rise above ambient. The PIC32MX320F128LT-80V/PT typically dissipates less than 200 mW in normal operation, but at high core load (80 MHz with most peripherals active) it can reach 300-400 mW. For 'V' grade parts operating at +105 C ambient, ensure total system dissipation stays below 100 mW or the die temperature may exceed the rated +125 C maximum junction.
Route the 32.768 kHz secondary oscillator (SOSCO/SOSCI) traces as short, symmetric traces enclosed by a ground guard ring to minimize coupling from switching noise. Separate analog inputs (AN0-AN15) from digital switching lines by at least 3x the trace-to-trace spacing, and connect AVSS to the same ground plane as VSS with a single tie-point near the IC. The exposed pad variant (if present) should be soldered to a ground pour for thermal spreading.
Do not configure unused pins as floating inputs - they consume leakage current and act as noise antennas. Default all unused pins to outputs with logic-low or to inputs with the internal pull-up enabled. When migrating from PIC24/PIC18, remember that the PIC32 configuration bits differ from PIC24 and that the device ID register is at a different address; using the wrong peripheral library header produces subtle bugs that are hard to debug. Also note that PIC32MX code typically runs from the same Flash addresses after reset, so startup code and bootloader configuration must match the chosen memory map.
