PIC32MX430F064H-I/RG - 100MHz 32-bit MCU 64KB Flash | Microchip
MPN: PIC32MX430F064H-I/RG ✓ Hoạt độngPIC32MX430F064H-I/RG Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, timers, communication peripherals, and I/O on one silicon die. The PIC32MX family sits in the hierarchy MIPS32 core -> 32-bit MCU -> embedded microcontroller -> semiconductor IC, and the MX3/4 sub-family targets cost-sensitive industrial and consumer applications needing USB connectivity and ample analog integration.
Key features of the PIC32MX430F064H include 64 KB program Flash with self-programmability, 16 KB SRAM, an 8-channel 10-bit ADC, five 16-bit timers/counters, a real-time clock with alarm, and a USB 2.0 full-speed device controller with internal pull-up. The 5V-tolerant I/O simplifies interfacing to legacy 5V logic without level shifters, and the 49 available I/O pins offer generous connectivity in the compact 64-VQFN.
Architecturally the M4K pipeline executes up to 150 DMIPS at 120 MHz, with single-cycle multiplication and hardware multiply-accumulate support. The internal 8 MHz Fast RC oscillator with PLL provides flexible clocking while reducing external BOM cost. The device operates from 2.3V to 3.6V and is industrial-temperature graded from -40C to +85C.
Typical applications include USB peripherals, industrial control panels, sensor hubs, low-cost graphical HMI, and small embedded data loggers. The combination of USB device, ample RAM, and 64-VQFN footprint suits space-constrained industrial boards.
When designing with this board, pay attention to decoupling - place 100 nF ceramic capacitors on every VDD/VSS pair and a bulk 4.7 uF near the regulator. Use the JTAG retention clock and trace practice to avoid EMI on the USB DP/DM lines, and ensure the VBUS pin sees 5V tolerant input as documented in the device datasheet.

Ghi chú thiết kế
Place one 100 nF ceramic decoupling capacitor on every VDD/VSS pair and a 4.7 uF bulk cap within 1 cm of the IC. The USB VBUS pin must see 5V-tolerant input as documented in the device datasheet; use a resistor divider or ferrite bead if the source is not 5V. Decoupling ensures clean USB DP/DM signaling and prevents VDD droop during USB enumeration.
Route the USB DP/DM lines as a 90 ohm differential pair with matched length and continuous reference plane to the IC GND. Place the 27 ohm series resistors close to the IC pins per the device datasheet. The exposed thermal pad must be soldered to a continuous copper pour connected to VSS to provide the thermal and electrical return path.
Do not skip the 0.1 uF bypass cap on the AVDD/AVSS analog supply pair even if analog inputs are not used. Configure unused I/O as outputs low to minimize supply current. When migrating from the PIC32MX330F064H-I/RG (no USB), verify firmware does not rely on the USB module registers since the USB peripheral is not present in the 330 variant.
Estimated: The 100 MHz CPU clock produces 10 ns rise times on GPIO; if driving long traces or capacitive loads, add a 33 ohm series resistor to dampen reflections. Keep crystal traces short (<10 mm) and guard with a GND ring to avoid coupling into the USB DP/DM lines or ADC analog inputs.
