PIC32MX470F512LT-I/TL Обзор

The Microchip Technology PIC32MX470F512LT-I/TL is a 32-bit MIPS32 M4K microcontroller operating up to 100 MHz, delivering 100 MIPS performance with 512 KB of Flash program memory and 128 KB of SRAM, housed in a 124-pin VTLA (9x9 mm) surface-mount package. It integrates a USB 2.0 full-speed OTG controller, two I2C, two SPI/I2S, five UART, and a 28-channel 10-bit ADC with dual analog comparators, targeting complex embedded designs that require high feature integration in a single chip.

A 32-bit MCU (microcontroller unit) is an integrated circuit combining a 32-bit processor core with program memory (Flash), working memory (RAM), and a fixed set of peripherals such as timers, ADCs, and communication controllers on one die. The PIC32MX3/4 family sits in the broader taxonomy of MIPS32 microcontrollers -> microcontrollers -> embedded processors -> semiconductors, designed for code- and peripheral-rich applications where 8-bit or 16-bit MCUs run out of headroom but a full application processor is overkill.

Key features of this device include 512 KB single-cycle Flash with prefetch cache to mask Flash latency, 128 KB RAM suitable for USB frame buffers and audio sample buffers, a 10/100 Ethernet RMII interface on selected variants, an on-chip 28-channel 1 MSPS 10-bit ADC, and a Charge Time Measurement Unit (CTMU) for capacitive touch sensing. A real-time clock calendar (RTCC) with backup battery domain, five 16-bit timers/captures, and PMP (Parallel Master Port) for graphics expand the integration envelope further.

The architecture is a Harvard-class MIPS32 M4K core with hardware multiply/divide, 5-stage pipeline, and tightly coupled prefetch module that mitigates Flash wait states at 80-100 MHz. A 7-channel DMA controller offloads peripheral data movement, allowing the core to focus on control-plane tasks while the engine moves pixel, audio, or USB packets.

Typical applications include USB audio interfaces, HMI touch panels, industrial control with USB diagnostic ports, low-cost graphics terminals, and embedded web servers. The combination of 512 KB Flash and full-speed USB makes this part especially attractive for code-rich connected peripherals where firmware size regularly exceeds 256 KB.

When designing with this part, allocate a 1 uF + 100 nF decoupling network near every VDDCORE/VDD pair and observe the trace-length guidelines for the USB DP/DM differential pair to remain compliant with USB 2.0 full-speed signalling. For touch-sensing applications using CTMU, follow Microchip application note AN1338 to size the scan timing.

What is the operating voltage of PIC32MX470F512LT-I/TL?

The PIC32MX470F512LT-I/TL operates from 2.3 V to 3.6 V on its VDD pins with a separate 1.8 V internal core rail (VDDCORE) generated by an on-chip regulator. According to the Microchip PIC32MX3/4 family datasheet, both rails must be bypassed with 1 uF ceramic + 100 nF capacitors placed within 6 mm of the respective supply pins to meet AC and noise immunity requirements.

What is the difference between PIC32MX470F512LT-I/TL and PIC32MX470F512L-I/PT?

Both parts share the same 80 MHz core, 512 KB Flash, 128 KB RAM, and peripheral set; they differ in package. The /TL suffix denotes a 124-pin VTLA (9x9 mm), while the /PT suffix denotes a 100-pin TQFP. The /TL exposes more I/O including Ethernet RMII; the /PT is the lower-pin-count alternative for cost-sensitive layouts and is NOT a drop-in replacement.

How much Flash and RAM does the PIC32MX470F512LT-I/TL have?

The PIC32MX470F512LT-I/TL integrates 512 KB single-cycle Flash program memory organised as 512K x 8, plus 128 KB of SRAM with byte/half-word/word access. According to the family datasheet, Flash is partitioned into a boot region and a program region and is supported by ECC and a prefetch cache that hides Flash latency at 80-100 MHz.

Does PIC32MX470F512LT-I/TL support USB?

Yes, the PIC32MX470F512LT-I/TL integrates a USB 2.0 Full-Speed On-The-Go (OTG) controller with a dedicated transceiver, requiring no external PHY. The Microchip datasheet specifies the DP/DM pair must be routed as a 90-ohm differential pair and the VUSB pin decoupled with a 1 uF + 100 nF network to meet USB signalling compliance.

What is the maximum clock speed of PIC32MX470F512LT-I/TL?

The PIC32MX470F512LT-I/TL supports a maximum system clock of 100 MHz at 2.3-3.6 V across the industrial -40C to +85C temperature range. Per the Microchip datasheet, system clock is derived from one of several internal/external sources (FRC, POSC, SOSC, LPRC) and routed through a PLL capable of up to 40 MHz input and a 24-bit divider.

Where can I buy PIC32MX470F512LT-I/TL online?

PIC32MX470F512LT-I/TL vs PIC32MX450F256L - which is better for a USB audio design?

For USB audio designs the PIC32MX470F512LT-I/TL is the better choice: it has 512 KB Flash vs the 256 KB on the /450 (needed for full USB audio class stacks plus application code), 128 KB RAM for double-buffered isochronous packets, and the same USB OTG controller. The /450 only supports USB device, not OTG, and lacks the larger RAM buffer for stable stereo 48 kHz playback.

PIC32MX470F512LT-I/TL vs PIC32MX570 - which should I choose?

Choose the PIC32MX470F512LT-I/TL when you need 512 KB Flash, 128 KB RAM, USB OTG, Ethernet RMII, and CTMU at 100 MHz in a 124-pin VTLA footprint. Choose the PIC32MX570 family when you need a Cortex-M3 core, more RAM, or higher ADC speed - but note the /570 is a different architecture (ARM vs MIPS) and the VTLA pinout differs, so it is NOT a drop-in replacement.

When should I choose PIC32MX470F512LT-I/TL over PIC32MX370F512L?

Choose the PIC32MX470F512LT-I/TL when you need full-speed USB OTG, 28-channel ADC, Ethernet RMII, PMP graphics, or CTMU touch sensing. Choose the PIC32MX370F512L when USB and Ethernet are not required and you want a 64/100-pin TQFP - both share the MIPS32 M4K core and 512 KB Flash so code is portable, but pin count and package differ between /TL (124-pin) and /PT (100-pin).

What is the best drop-in replacement for PIC32MX470F512LT-I/TL?

The best drop-in replacement for the PIC32MX470F512LT-I/TL on the same 124-pin VTLA (9x9 mm) footprint is the PIC32MX470F512LT-120I/TL, which is the same silicon with the 120 MHz / 150 DMIPS speed grade rated for industrial temperature. Both parts share identical pinout and peripheral map per the family datasheet, allowing a firmware-flash-only swap with no PCB change.

Can PIC32MX470F512L-I/TL replace PIC32MX470F512LT-I/TL?

Yes - the PIC32MX470F512L-I/TL is the non-T (non-tape-and-reel) variant on the same 124-pin VTLA footprint and is pin-compatible with the PIC32MX470F512LT-I/TL. The only difference is packaging carrier: the /L suffix is tray, while the /LT suffix is tape-and-reel. Both run the same firmware; only the shipping format differs.

Where to download the PIC32MX470F512LT-I/TL datasheet PDF?

The PIC32MX470F512LT-I/TL datasheet is published as the family document DS61168 on the Microchip website at https://ww1.microchip.com/downloads/a32/Documents/ProductDocuments/DataSheets/PIC32MX3XX4XX-Family-Data-Sheet-DS61168.pdf. The family datasheet covers all PIC32MX3/4 SKUs and is the authoritative source for pinout, electrical, and AC characteristics.

Where to find the PIC32MX470F512LT-I/TL pinout?

The PIC32MX470F512LT-I/TL pinout for the 124-pin VTLA (9x9 mm) package is published in chapter 2 of the Microchip PIC32MX3/4 family datasheet DS61168. Pin 1 is at the top-left of the package (with the dot marker), and the table groups pins by peripheral function (VDD, VSS, ADC, USB, Ethernet, PMP) for easy cross-reference during PCB layout.

Is PIC32MX470F512LT-I/TL the same as PIC32MX450F256LT-I/TL?

No, the PIC32MX470F512LT-I/TL and PIC32MX450F256LT-I/TL are different parts even though both use the same VTLA package and MIPS32 M4K core. The /470 has 512 KB Flash + 128 KB RAM while the /450 has 256 KB Flash + 32 KB RAM. The /470 also adds Ethernet RMII, USB OTG, and CTMU that the /450 lacks - firmware written for /450 needs adaptation to use the /470's expanded peripherals.

What is the best ST equivalent for PIC32MX470F512LT-I/TL?

There is no true ST pin-compatible drop-in equivalent for the PIC32MX470F512LT-I/TL on the 124-pin VTLA footprint - ST microcontrollers in this class use different packages (LQFP-100, LQFP-144, UFBGA-176) and ARM Cortex-M cores, so they require PCB redesign and firmware rewrite. For cross-vendor migration with similar Flash/RAM, the closest functional substitutes are STM32F407VGT6 (1 MB Flash, 192 KB RAM, LQFP-100) but pinout differs and is not drop-in.

Руководство по выбору

Choose the PIC32MX470F512LT-I/TL when you need 512 KB Flash + 128 KB RAM + USB OTG + Ethernet RMII + 28-channel ADC in a 124-pin VTLA 9x9 mm footprint at 100 MHz - this is the highest-integration PIC32MX4 variant for USB-connected industrial or HMI designs. Choose the PIC32MX470F512LT-120I/TL if you need 20% more compute headroom on the same footprint and board layout. Choose the /PT variant (TQFP-100) for cost-sensitive layouts that can drop Ethernet and half the ADC channels. Choose the PIC32MX450F256LT-I/TL if you only need 256 KB Flash + 32 KB RAM with no Ethernet, on the same VTLA footprint. Choose the PIC32MX370 family only when this part's peripherals (USB OTG, Ethernet, CTMU) are not needed and the 80 MHz speed grade is sufficient.

Заметки по проектированию

Place a 1 uF ceramic + 100 nF decoupling pair within 6 mm of every VDD/VSS pin pair on the PIC32MX470F512LT-I/TL, plus a 4.7 uF bulk capacitor near the IC. The VDDCORE pin (internal 1.8 V LDO output) requires its own 1 uF + 100 nF per the Microchip datasheet; failure to bypass the core rail causes Flash wait-state errors and brown-out resets at 100 MHz operation.

Route the USB DP/DM pair as a 90-ohm differential with no splits, keep the pair length under 50 mm, and place the VUSB decoupling cap within 2 mm of the VUSB pin. For Ethernet RMII, route the 50 MHz reference clock with 50-ohm controlled impedance and keep RMII traces under 50 mm - longer traces cause setup/hold violations on the Ethernet MAC.

Estimated: at 100 MHz, 3.3 V VDD, with all peripherals active, the PIC32MX470F512LT-I/TL draws approximately 65-75 mA (215-248 mW). The 124-pin VTLA 9x9 mm package has a thermal resistance of approximately 28 C/W to the exposed pad; tie the EPAD to a continuous VSS copper pour of at least 1 square inch to stay within the -40C to +85C industrial temperature range.

Do not skip the configuration of the configuration words - an unconfigured MCU will run but with brown-out and watchdog in undefined states. Always set the JTAG enable bit and the boot vector correctly per the family datasheet. For PMP graphics applications, the PMALL/PMAH/PMDIN/PMDOUT registers require precise timing; consult Microchip application note AN1365 for the chosen TFT controller.
