MPN: PIC32MX350F128H-I/PT ✓ AktifPIC32MX350F128H-I/PT Ringkasan
A 32-bit microcontroller (MCU) is an embedded processor that executes instructions on a 32-bit data path, enabling higher code performance, more addressable memory, and richer peripheral integration than 8-bit or 16-bit predecessors. The PIC32 family uses the MIPS32 M4K Harvard architecture with separate instruction and data buses, sitting in the hierarchy: 32-bit MCU -> microcontroller -> embedded processor -> semiconductor IC. PIC32MX3/4 series parts target cost-effective applications that demand 32-bit performance without paying for higher-tier Cortex-M cores.
Key features include 128 KB Flash program memory (with an additional 12 KB auxiliary Flash), 32 KB SRAM data memory, two I2S/SPI modules for audio codec interfaces, Peripheral Pin Select (PPS) for flexible signal routing, Parallel Master Port (PMP) for graphics displays, Charge Time Measurement Unit (CTMU) for capacitive touch sensing, and a 10-bit ADC. The I-suffix industrial temperature grade spans -40C to +85C, and operating voltage is 2.3V to 3.6V. The TQFP-64 footprint simplifies PCB layout and hand-prototyping versus QFN variants.
The MIPS32 M4K core implements a 5-stage pipeline with hardware multiply/divide, single-cycle 32-bit ALU operations, and deterministic interrupt response. Five 16-bit and two 32-bit timers provide flexible timing, and the integrated USB 2.0 full-speed device/host/OTG controller removes the need for an external PHY in many designs.
Typical applications include industrial control and HMI panels, USB peripherals, audio playback devices with I2S codecs, capacitive-touch user interfaces, and low-cost graphics terminals using small TFT displays driven by PMP. The 53 GPIO count and PPS flexibility allow pin-limited packages to expose most peripherals simultaneously.
Design consideration: use MPLAB X IDE with the XC32 compiler for code development and ICD3/REAL ICE for in-circuit debugging. Plan the ICSP PGECx/PGEDx pin pair assignment carefully because any pair is acceptable but both pins of a pair must be used together. Add bulk + bypass decoupling (10uF + 100nF) at each VDD/VSS pair to ensure stable operation across the 2.3-3.6V range.

Aplikasi Umum
PIC32MX350F128H-I/PT cocok untuk 7 aplikasis: Industrial HMI Control Panels, USB HID Peripheral Devices, Audio Playback with I2S DAC, Capacitive Touch User Interfaces, Low-Cost Graphics Terminals, IoT Sensor Edge Nodes, Motor Control and Drive Interfaces.
Industrial HMI Control Panels
The PIC32MX350F128H-I/PT fits industrial HMI panels because its MIPS32 M4K core at 80 MHz delivers the 131 DMIPS throughput required for menu rendering and real-time input handling on Parallel Master Port (PMP)-driven TFT displays. The integrated Charge Time Measurement Unit (CTMU) enables robust capacitive touch sensing without an external touch controller, reducing BOM cost. With 53 GPIO via Peripheral Pin Select, the part can drive a 4.3-inch QVGA TFT plus multiple LEDs, relays, and keypad rows simultaneously from a single chip. The industrial -40C to +85C temperature grade ensures reliable operation in factory-floor enclosures.

Diferensiator Kunci
- Drop-in upgrade path to 256 KB Flash without PCB rework (vsPIC32MX450F256H-I/PT)
- Higher memory than lower-tier PIC32MX330 family in same package (vsPIC32MX330F064H-I/PT)
- Higher performance than predecessor PIC32MX340 family (vsPIC32MX340F128H-80I/PT)
Catatan Desain
Place a 10uF bulk tantalum or ceramic capacitor at each VDD/VSS pin pair, plus a 100nF ceramic bypass capacitor within 5mm of every VDD pin. The PIC32MX350F128H-I/PT has multiple VDD/VSS pins distributed around the 64-TQFP package; inadequate decoupling causes code execution failures and ADC measurement errors. The 2.3V to 3.6V supply range requires tight regulation - use an LDO with PSRR greater than 50 dB at 1 MHz to prevent switching noise from affecting USB operation.
Route the 80 MHz system clock traces with 50-ohm controlled impedance and keep them away from analog traces like the ADC inputs. Place the 8 MHz primary crystal or resonator within 5mm of the OSC1/OSC2 pins with short traces and a ground guard ring. For USB designs, route D+ and D- as a 90-ohm differential pair with no stubs, matching length within 150 mil. Add ESD protection diodes (USBLC6-2 or equivalent) at the USB connector.
When using the ICSP programming/debug interface, you must use any pair of PGECx/PGEDx pins as a pair - if you select PGEC2, ICSPDAT must be connected to PGED2. MCLR must have a 10kohm pull-up to VDD or programming will fail. For Peripheral Pin Select (PPS), configure the peripheral input/output mapping registers before enabling the peripheral; misconfiguration is a common source of no-operation issues. The 53 GPIO count assumes PPS remapping is configured - many pins share alternate functions at reset.
The 64-TQFP package has a theta_JA around 50 C/W in still air, which is generally adequate for the PIC32MX350F128H-I/PT's typical 30-40 mA active current at 80 MHz (around 130 mW at 3.3V). However, in enclosed industrial enclosures above 60C ambient, verify thermal margin by measuring the case temperature during worst-case operation. For higher ambient environments, choose the -V (automotive -40C to +105C) variant which shares the same 64-TQFP footprint.
