PIC32MX230F128L-V/PF - 32-bit 50MHz 128KB Flash MCU TQFP-100 | Microchip
MPN: PIC32MX230F128L-V/PF ✓ Hoạt độngPIC32MX230F128L-V/PF Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, and programmable peripherals. The PIC32MX230F128L belongs to the MIPS32 M4K architecture family, which sits in the 32-bit MCU category alongside ARM Cortex-M parts; it is broadly classified as a microcontroller -> embedded processor -> semiconductor. Within Microchip's PIC32 line, the PIC32MX2xx sub-family is the cost-optimized tier offering USB, PMP, and PPS peripherals at higher pin counts.
Key features include 128 KB Flash, 16 KB SRAM, two I2S and four SPI modules, Peripheral Pin Select (PPS) for flexible signal routing, a Parallel Master Port (PMP) with dual buffers for graphics interfaces, a 16-channel 10-bit 1 Msps ADC, four UART modules, two I2C, five 16-bit timers/counters, and CTMU. The 50 MHz M4K core delivers up to 83 DMIPS performance, sufficient for human-machine interface (HMI), USB device, and embedded connectivity designs.
The device integrates a 5-stage pipeline, hardware multiply/divide, single-cycle MAC, prefetch buffer, and a JTAG/ICSP debug interface. The PMP peripheral simplifies connection to graphical LCD controllers, while PPS allows remapping of digital peripherals to almost any I/O, easing PCB layout. These features give designers flexibility similar to higher-tier Cortex-M0+ MCUs while keeping the Microchip MPLAB X toolchain.
Typical applications include industrial control boards, USB device peripherals, HMI touch panels, audio playback with I2S DAC, sensor hubs, and general-purpose embedded designs. Drop-in variants in the same 100-pin TQFP exist with different Flash/RAM densities (PIC32MX230F064, PIC32MX150F256, PIC32MX170F512) for upward/downward memory migration without PCB rework.
When designing, ensure decoupling capacitors are placed as close as possible to each power pin (100 nF X7R per pin, plus a bulk 4.7 uF on VDD). Configure PPS carefully - unused remapped pins default to general I/O. A 12 MHz external crystal or internal 8 MHz FRC with PLL is typically used to reach 50 MHz core clock.

Industrial Control Boards
The PIC32MX230F128L-V/PF fits industrial control boards due to its -40C to +105C operating temperature grade (suffix "V") and 50 MHz / 83 DMIPS performance on the MIPS32 M4K core. The 128 KB Flash supports Modbus, CANopen, or EtherCAT slave protocol stacks, while 16 KB SRAM buffers real-time control loops. The 16-channel 10-bit ADC at 1 Msps samples sensor arrays and motor feedback currents simultaneously. Industrial designs benefit from JTAG/ICSP debug via PICkit 4 for field firmware updates.

Ghi chú thiết kế
Decoupling per the Microchip datasheet: place a 100 nF X7R ceramic capacitor on every VDD/AVDD pin and a single 4.7 uF bulk capacitor close to the IC. The PIC32MX230F128L-V/PF integrates a 1.8V core voltage regulator fed from the main VDD rail; its VDDCORE pin requires a 4.7 uF + 100 nF local capacitor. Avoid routing high-frequency signals across the VDDCORE capacitor to prevent noise coupling into the PLL.
The TQFP-100 package has a theta_JA of approximately 50 C/W on a standard 4-layer JEDEC test board. At 50 MHz full activity with all peripherals on, core current is approximately 30 mA. Estimated: at 3.3V VDD x 30 mA = 99 mW, junction temperature rise is ~5 C - well within the -40C to +105C operating range. Industrial designs above 70C ambient should verify junction temperature with the actual PCB copper area used.
Route the 50 MHz system clock trace as short and straight as possible, surrounded by ground stitching vias. The OSCREF crystal traces must be symmetric and short to avoid duty cycle distortion. Use PPS to remap high-speed peripherals like SPI and I2S away from analog-capable pins to reduce crosstalk on the 10-bit ADC inputs. Place a ground pour on the top layer under the TQFP for thermal dissipation and signal integrity.
Do not forget to configure the wait-state bits in the Flash controller when running above 30 MHz - failure to do so causes unstable execution. The PMP peripheral requires careful timing configuration for graphics LCDs; consult the PIC32 Family Reference Manual section on PMP. When migrating from PIC32MX130F128L-I/PF, verify PPS register compatibility - some PPS input mappings differ between sub-families.
