PIC32MX450F128L-V/TL Ringkasan

The Microchip Technology PIC32MX450F128L-V/TL is a 32-bit MIPS32 M4K microcontroller running up to 80 MHz, integrating 128 KB Flash and 16 KB SRAM in a 124-pin VTLA (9x9 mm) surface-mount package with exposed pad. It belongs to the PIC32MX3/4 family, designed as a low-cost 32-bit MCU with USB 2.0 full-speed (USB-OTG), two SPI/I2S interfaces, two I2C, two UART, an 8-bit PMP for graphics or external memory, and a 10-bit 1 Msps ADC with up to 28 analog channels.

A 32-bit microcontroller (MCU) is an integrated circuit that combines a 32-bit processor core, program and data memory, and a configurable set of on-chip peripherals (ADC, timers, communication interfaces, I/O) on a single silicon die. Microcontrollers sit at the top of the embedded-system hierarchy: system-on-module -> MCU -> CPU core -> instruction set, enabling battery-powered and cost-sensitive products to perform deterministic real-time control. The PIC32MX series uses the MIPS32 instruction set with the M4K pipeline to deliver up to 150 DMIPS while keeping active power below 1 mA/MHz in typical conditions.

Key features of the PIC32MX450F128L-V/TL include 128 KB Flash (128K x 8), 16 KB SRAM, USB 2.0 full-speed OTG with on-chip transceiver, two analog comparators with 2 us response, a 10-bit 1 Msps ADC with 28 channels, five 16-bit timers/captures, and a Parallel Master Port for graphics or memory expansion. The -V grade denotes an operating range of -40C to +105C; the /TL suffix identifies a 124-VTLA tray/tube packaging variant.

Architecturally the device uses a Harvard-style bus with separate Flash and RAM paths, a 5-stage M4K pipeline, and a multi-vector interrupt controller. The 124-VTLA package exposes up to 97 general-purpose I/O pins and a dedicated trace interface for real-time instruction trace through dedicated TRCLK/TRDx pins, which simplifies firmware debugging on production hardware.

Typical applications include USB-equipped industrial HMI panels, audio playback devices using SPI/I2S codecs, low-cost graphics terminals using the PMP bus, sensor aggregation hubs with USB-CDC virtual COM port, and USB HID/mouse/keyboard controllers. Its combination of USB, PMP, and 28-channel ADC makes it well suited to multi-signal embedded designs.

When designing with this part, allocate the exposed thermal pad (EP) directly under the IC to a continuous top-layer ground pour to keep junction temperature within the 105C operating envelope. The PIC32MX3/4 datasheet recommends a 10 uF + 0.1 uF decoupling pair on each VDD/VSS pin pair placed within 5 mm of the package, and a dedicated ferrite-bead-isolated USB VBUS rail to keep high-frequency USB transients away from the analog supply.

🏭

USB-Equipped Industrial HMI Panels

The PIC32MX450F128L-V/TL drives industrial HMI panels by combining USB 2.0 Full-Speed OTG (allowing PC-based configuration and firmware update without an external programmer), an 8-bit Parallel Master Port for direct graphics LCD interfacing, and a 10-bit 1 Msps ADC with 28 channels for back-panel sensor inputs. The 80 MHz MIPS32 M4K core handles touch-screen decoding plus on-screen graphics refresh at 30-60 Hz, while 128 KB Flash fits mid-sized LVGL/Micrium GUI applications. Practical: dedicate the on-chip USB transceiver to a USB-C receptacle with ESD protection (USBLC6-2SC6), and place a 100 uF tantalum plus 0.1 uF ceramic on VBUS to keep inrush below USB 2.0 spec.

🎧

USB Audio Playback Devices

The PIC32MX450F128L-V/TL enables low-cost USB audio peripherals by acting as a USB Full-Speed audio device and streaming PCM samples over I2S to an external audio DAC. The two integrated SPI/I2S modules support up to 48 kHz / 16-bit stereo streams, while the integrated USB 2.0 OTG transceiver eliminates the need for an external PHY. The 80 MHz core, 16 KB SRAM, and DMA engine support concurrent USB isochronous transfer and I2S DMA with sub-frame jitter. Practical: connect I2S BCLK/LRCK/DATA to a TI TLV320AIC23B or AKM AK4621A codec, and use a 12.288 MHz crystal to provide 256 x 48 kHz audio master clock without an external PLL.

🧩

USB HID Keyboards / Mice / Gamepads

The PIC32MX450F128L-V/TL supports USB HID input devices via the on-chip USB OTG transceiver and 5 16-bit timers for matrix/keyboard scanning. Its 80 MHz core debounces up to an 8x16 key matrix at 1 kHz, with 128 KB Flash storing multiple HID report descriptors (boot keyboard, mouse, gamepad) and 16 KB SRAM large enough for keyboard rollover buffers. The 124-VTLA exposes 97 GPIO for direct matrix drive. Practical: add 33 ohm series resistors on D+/D-, place a ferrite bead on VBUS to suppress ESD, and use 5 V-tolerant I/O to read older 5 V scan matrices directly.

⚡

Multi-Channel Sensor Aggregation Hubs

The PIC32MX450F128L-V/TL aggregates industrial sensors via its 28-channel 10-bit 1 Msps ADC, two I2C buses (for digital sensors), two analog comparators (for fast over-current or threshold detection), and uploads telemetry through USB CDC. The 5 16-bit timers pace multi-rate sampling (e.g., 100 Hz temperature, 1 kHz vibration), and 16 KB SRAM holds 1024-sample ring buffers. Practical: add a 4.7 nF RC plus op-amp buffer to each analog input for ADC source impedance below 2 kohm, and isolate the USB D+/D- lines with a common-mode choke to reject EMI in motor cabinets.

What is the maximum CPU clock speed of the PIC32MX450F128L-V/TL?

The PIC32MX450F128L-V/TL runs up to 80 MHz from its internal FRC/PLL, delivering up to 150 DMIPS in the PIC32MX3/4 family. According to the Microchip PIC32MX3XX/4XX family datasheet, the system clock is software-configurable up to 80 MHz at 2.3-3.6 V across the full -40C to +105C (V-grade) temperature range. Note: the family supports 120 MHz on PIC32MX4 siblings; this 450F128L variant is rated at 80 MHz.

How much Flash and SRAM does PIC32MX450F128L-V/TL have?

The PIC32MX450F128L-V/TL integrates 128 KB of Flash program memory organized as 128K x 8 and 16 KB of SRAM. Both numbers are stated in the Microchip PIC32MX450F128L datasheet and on distributor listings such as DigiKey (product 4080149) and Mouser. The Flash is in-application programmable through ICSP, and SRAM is byte-addressable with DMA-capable regions for USB and PMP traffic.

Does PIC32MX450F128L-V/TL include a USB 2.0 controller?

Yes. The PIC32MX450F128L-V/TL integrates a USB 2.0 Full-Speed On-The-Go controller with an on-chip transceiver, supporting host, device, and OTG roles without an external PHY. According to the Microchip datasheet, the USB module shares dedicated VBUS/VUSB pins on the 124-VTLA package and integrates pull-up/pull-down resistors for bus signaling.

What is the difference between PIC32MX450F128L-V/TL and PIC32MX450F128LT-V/TL?

The PIC32MX450F128LT-V/TL is the lead-free (T) and 125C (extended) variant of the same die, while the PIC32MX450F128L-V/TL is the standard commercial/V-grade (105C) part in tube packaging. Both share the same 124-VTLA (9x9 mm) footprint and pinout, so they are drop-in compatible. Choose -T (DigiKey 4080149) for higher temperature or lead-free BOM mandates.

Is the PIC32MX450F128L-V/TL pin-compatible with PIC32MX470F512L-V/TL?

Yes. The PIC32MX470F512L-V/TL is a higher-memory sibling (512 KB Flash, 128 KB SRAM) in the same 124-VTLA (9x9 mm) package and the same PIC32MX4 family. Per the Microchip datasheet, both parts share the identical 124-pin VTLA pinout and exposed pad, so they are drop-in compatible. Use 470 if you need more code/data space; otherwise 450F128L is the lower-cost choice.

PIC32MX450F128L-V/TL vs PIC32MX440F128L - which is better for USB?

The PIC32MX450F128L-V/TL is the correct choice over PIC32MX440F128L for USB applications because the 450 family integrates the USB 2.0 Full-Speed OTG controller with on-chip transceiver, while the 440 family lacks the integrated USB transceiver. Both share the 124-VTLA option, but for USB HID, CDC, or audio you must use the 450F128L (or 470F512L) part.

Can I replace PIC32MX450F128L-V/TL with PIC32MX450F128LT-V/TL directly?

Yes. The PIC32MX450F128LT-V/TL is the same silicon die in the same 124-VTLA (9x9 mm) package, differing only in temperature grade (125C vs 105C) and lead-free (Pb-free) terminal finish. Per the Microchip PIC32MX3/4 datasheet, both share pinout and ICSP programming, so the -T variant is a true drop-in replacement if your design accepts the higher temperature ceiling.

Panduan Pemilihan

Choose the PIC32MX450F128L-V/TL for USB 2.0-equipped industrial HMI, audio, or sensor designs that need 128 KB Flash and 80 MHz CPU in a 124-VTLA footprint with -40C to +105C operating range. If your code approaches 128 KB, step up to PIC32MX470F512L-V/TL (512 KB Flash, 128 KB SRAM, identical 124-VTLA pinout) without changing PCB layout. For 125C deployment, use PIC32MX450F128LT-V/TL (drop-in). If USB is not needed, PIC32MX370F512L-V/TL saves money; if cost is paramount and USB is required, PIC32MX270F512L in 100-TQFP is the alternative. All alternatives share the Microchip PIC32MX3/4 MIPS32 M4K core and MPLAB X toolchain compatibility.

Catatan Desain

Estimated: For a 124-VTLA board running 80 MHz MIPS M4K at 3.3 V, place a 10 uF + 0.1 uF ceramic decoupling pair within 5 mm of every VDD/VSS pin pair. Add a dedicated 4.7 uF + 100 nF on VUSB3V3 (pin 111) and a separate ferrite-bead-isolated 3.3 V LDO for the USB transceiver to keep switching noise off the analog supply. Decoupling the AVDD/AVSS pins (123, 124) with 100 nF ceramic plus 10 uF bulk reduces ADC noise by 1-2 LSB.

Estimated: at 80 MHz and 3.3 V, active current is approximately 55-65 mA (per family datasheet typical at 1 mA/MHz plus I/O leakage), so power dissipation is roughly 200 mW. The 124-VTLA exposed pad must be soldered to a top-layer ground pour of at least 25 x 25 mm to keep theta_JA below 25 C/W; without the EP soldered, junction temperature will exceed 105C under load.

Route the USB D+/D- differential pair (RG6, RG7) with 90 ohm differential impedance and 33 ohm series source resistors placed within 5 mm of the IC. Use a common-mode choke (e.g., ACM2012) near the USB receptacle to suppress common-mode emissions, and place a USBLC6-2SC6 ESD array within 10 mm of the connector. Keep trace length matching under 0.5 mm to meet USB 2.0 FS signal-integrity requirements.

Do not assume the 124-VTLA and 100-TQFP packages are interchangeable. PIC32MX450F128L is offered in 100-TQFP (PIC32MX450F128L-V/PF, DigiKey 4080150) with a different pinout - substituting one for the other requires PCB rework. Always verify the package code suffix (TL = VTLA tube, PT = TQFP tray, PF = TQFP tray) before finalizing the BOM. Also note the -V grade is 105C, not 125C; choose the -LT/-T variant for higher temperatures.

Keep the 12 MHz primary oscillator traces (OSC1, OSC2) short (under 10 mm) and surround them with a ground guard ring to reduce EMI susceptibility. Place the ICSP pins (PGED1/PGEC1, PGED2/PGEC2) on accessible PCB test pads for field firmware update, and isolate them from analog signals by at least 3 mm to avoid digital switching noise coupling into ADC channels.
