The "T" suffix denotes tape-and-reel packaging, the "V" suffix indicates the automotive/extended temperature grade, and the "/ML" suffix identifies the 28-pin QFN package. What is a PIC32 microcontroller? A PIC32MX is a 32-bit microcontroller from Microchip's PIC32 family, built on the MIPS32 M4K architecture and positioned between the 8-bit PIC16/PIC18 families and the higher-end Cortex-M class parts. PIC32MX MCUs combine deterministic interrupt response, USB 2.0 Full-Speed On-The-Go, and rich analog peripherals, making them a popular choice for cost-sensitive embedded designs that need more horsepower than 8-bit parts but do not require an RTOS-class Cortex-M4 core.

The combination of USB OTG, PMP, and PPS enables compact human-machine-interface and connectivity designs. Architecturally, the PIC32MX1xx/2xx family uses a single-cycle 32-bit MIPS M4K core with hardware multiply/divide, 5-stage pipeline, and prefetch cache for sustained throughput at 50 MHz. Memory is organized as a unified 256 KB Flash block plus 64 KB SRAM, supporting a bootloader and field firmware updates. The 28-QFN package uses an exposed thermal pad to dissipate the ~150 mW core power envelope, and the part supports 2.3 V to 3.6 V single-supply operation. Typical applications include industrial USB-to-UART bridges, automotive body and HMI controllers (dashboards, climate panels), capacitive touch user interfaces, sensor aggregation nodes with USB diagnostics, and low-cost graphics terminals using PMP-driven TFTs. The integrated USB OTG controller eliminates the need for an external PHY in CDC-class device designs. A primary design consideration is supply decoupling. Place a 0.1 uF ceramic capacitor as close as possible to each VDD/VSS pair, plus a bulk 10 uF near the regulator output. The PPS feature must be configured in software at startup; failure to do so will leave peripherals mapped to default pins and may cause apparent "dead" I/O on custom layouts.

The 44-VTLA package is the thinnest variant (0.5 mm nominal height), well-suited to space-constrained handhelds where the QFN (ML) and TQFP (PT) alternatives are taller. Designers porting between VTLA, QFN, and TQFP must verify pinout tables because lead pitch differs (0.4 mm VTLA, 0.65 mm QFN, 0.8 mm TQFP); the silicon is identical, but the PCB footprint cannot be reused. Typical applications include USB audio interfaces, USB HID peripherals, sensor hub controllers, small graphical user interfaces (PMP-driven TFT), industrial USB-to-UART bridges, and consumer learning/evaluation boards such as the PIC32MX USB Starter Kit. A critical design consideration is the 2.3-3.6 V supply range: any 5 V signal requires level translation, and the 44-VTLA package is moisture-sensitive (MSL-3), demanding dry-pack handling and reflow profiles below 260 C peak. This page aggregates distributor pricing, drop-in alternative MPNs from the same VTLA-44 footprint, and design notes that go beyond the datasheet application examples to help engineers short-list replacement parts quickly.

The 512 KB Flash allows full feature stacks including USB stacks, graphics libraries, and bootloader/OTA support without external memory. When designing with this part, reserve an external 8 MHz or 12 MHz crystal and configure the PLL to derive 80 MHz (system) and 50 MHz (peripheral) clocks. The RTCC requires a 32.768 kHz crystal and a coin-cell backup supply for time retention; if unused, the SOSC pins can be remapped to GPIO via PPS configuration.

A 32-bit microcontroller (MCU) is an integrated circuit that contains a 32-bit processor core, program memory (Flash), data memory (SRAM), and a rich set of peripherals such as timers, communication interfaces, and analog blocks. The PIC32MX family specifically integrates the MIPS32 M4K core with Microchip's Peripheral Pin Select (PPS), giving designers unrivaled pin-out flexibility for mixed-signal boards. The hierarchy of the category: MCU -> 32-bit MCU -> MIPS-based MCU -> PIC32MX family -> PIC32MX170 sub-family -> general-purpose connected MCU with USB/CAN. Key features of the PIC32MX170F512L-I/PF include up to 50 MHz/83 DMIPS core, four SPI modules, two I2S modules for audio codecs, Peripheral Pin Select (PPS) for flexible pin assignment, a Parallel Master Port (PMP) with dual read/write buffers for graphics interfaces, mTouch capacitive touch sensing (CTMU), USB 2.0 Full-Speed device/host/OTG, CAN 2.0B, and a 10-bit 1 Msps ADC with up to 48 channels. The -I grade operates across the industrial -40C to +85C temperature range. Architecturally, the PIC32MX170F512L uses a 5-stage pipeline MIPS32 M4K core with single-cycle multiplication, hardware multiply/divide, and a tightly-coupled prefetch module that minimizes Flash wait states. The PIC32MX1XX/2XX/5XX family integrates an 8-channel DMA controller, a 16-bit Parallel Master Port for graphics or external memory, and a CTMU for capacitive touch measurement. Typical applications include industrial control HMI panels with TFT displays, USB-connected audio peripherals using I2S codecs, CAN-based automotive body controllers, USB-CDC debug bridges, capacitive touch user interfaces, and connected sensor hubs in IoT edge nodes. The 100-pin TQFP exposes nearly the full peripheral set including Ethernet RMII-ready pins. For PCB layout, route the two VDD/VDDIO pairs and multiple VSS pins with low-impedance copper pours, place a 10uF + 0.1uF decoupling pair within 5 mm of each power pin, and reserve the PGECx/PGEDx pair near the ICSP header to keep debug programming reliable. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes for the PIC32MX170F512L-I/PF that go beyond the manufacturer datasheet headline specifications.

PIC32MX170F512L-I/PT - 50MHz 32-bit MCU 512KB Flash | Microchip
PIC32MX170F512L-I/PT

PIC32MX170F512L-I/PT - 50MHz 32-bit MCU 512KB Flash | Microchip

The Microchip Technology PIC32MX170F512L-I/PT is a 32-bit MIPS32 M4K microcontroller running up to 50 MHz (83 DMIPS) with 512 KB Flash and 64 KB SRAM, housed in a 100-pin TQFP (PT, 12x12 mm) package. It integrates two I2S and four SPI modules, a Parallel Master Port (PMP) with dual read/write buffers for graphics, Peripheral Pin Select (PPS) for flexible remapping, mTouch capacitive touch, and a 10-bit 1 Msps ADC. What is a PIC32MX microcontroller? PIC32MX is Microchip's MIPS32 M4K-based MCU family positioned between 16-bit dsPIC/PIC24 and Cortex-M-class parts. It uses a Harvard-architecture 32-bit core with single-cycle multipliers, deterministic interrupt latency, and 16-bit instructions for code density, while remaining compatible with classic PIC peripherals. PIC32MX parts are widely used in HMI, USB audio, and industrial control designs. Key features of the PIC32MX170F512L include 50 MHz / 83 DMIPS performance, 512 KB Flash with pre-fetch cache, 64 KB RAM, USB 2.0 full-speed OTG, CAN 2.0B, two I2S, four SPI, five UART, five I2C, PMP for external memory/graphics, a 16-channel 10-bit 1 Msps ADC, five 16-bit timers/capture/compare, an RTCC, and Peripheral Pin Select (PPS) for nearly every digital function. The M4K core uses a 5-stage pipeline with branch shadowing and a hardware multiply/divide unit; Flash is mirrored into the 32-bit instruction fetch path through a 128-bit wide bus with a 4-word pre-fetch cache, while data passes through a separate SRAM bus, eliminating single-cycle Flash wait states in most cases. Typical applications include USB audio interfaces (USB + I2S + DAC chains), HMI panels with LCD via PMP, industrial CAN nodes, capacitive touch keypads, motor-control sequencers, and low-cost graphics + USB dongles. Industrial temperature grade (-40C to +85C) and the 100-pin TQFP give enough I/O for layered systems. Design consideration: when migrating from PIC24/dsPIC or PIC32MX3/4/5/6/7 families, verify PPS mapping because PIC32MX1xx has fewer remappable pins and a smaller RAM/Flash than PIC32MX5/6/7. Decoupling must include a 100 nF per VDD/AVDD pair and a bulk 4.7 uF on VDDCORE.

Architecturally the part uses a single-issue MIPS32 M4K core with hardware multiply/divide, 5-stage pipeline, and a 32-bit instruction path. The 512KB Flash is organized for in-circuit programming via 2-wire ICSP, and 64KB SRAM is supported by a 16-entry write buffer for sustained DMA bandwidth. JTAG debugging is available via PGECx/PGEDx pairs. Typical applications include USB audio peripherals, HMI panels with capacitive touch, CAN-based industrial nodes, low-cost graphics terminals, and consumer medical devices. With USB device, CAN, and PMP graphics on-chip, the PIC32MX170F512L removes the need for external bridges in many embedded designs. Design tip: at 40 MHz and full peripheral activity, power dissipation can reach roughly 75 mW (estimated from 2.5V/3.3V core supply and 33 mA run current); use the 100-pin TQFP copper pour to keep junction rise under 25 C/W. Decouple each AVDD/VDD pair with 0.1 uF plus 10 uF bulk capacitors placed within 5 mm of the pins.

PIC32MX170F512L-V/PT

PIC32MX170F512L-V/PT - 32-bit MCU 512KB Flash, 100-TQFP | Microchip

The Microchip Technology PIC32MX170F512L-V/PT is a 32-bit MIPS32 M4K microcontroller operating up to 50 MHz / 83 DMIPS, integrating 512 KB Flash and 64 KB SRAM in a 100-pin TQFP (12x12 mm) package. This AEC-Q100 qualified automotive-grade variant of the PIC32MX170 family supports 3.3 V operation and includes Peripheral Pin Select (PPS) for flexible pin function remapping, two I2S and four SPI modules for codec and serial communications, and a Parallel Master Port (PMP) with dual read/write buffers for graphics interfaces. The device also integrates a Charge Time Measurement Unit (CTMU) for mTouch capacitive touch sensing applications. What is a PIC32MX microcontroller? The PIC32MX1XX/2XX/5XX family is Microchip's mainstream 32-bit MIPS microcontroller line, bridging 8/16-bit PIC MCU users into 32-bit performance. Within the broader taxonomy, PIC32MX sits above 16-bit PIC24/dsPIC and below 32-bit PIC32MZ/Cortex-M4 devices, offering up to 83 DMIPS at 50 MHz with USB, CAN, and advanced peripherals. The '170' sub-family specifically targets audio/graphics/touch HMI applications with PMP graphics, I2S audio, and CTMU touch peripherals. Key differentiating features include 512 KB self-programmable Flash, 64 KB SRAM, USB 2.0 full-speed OTG, CAN 2.0B, up to 13 ADC channels (10-bit 1 Msps), five 16-bit timers/counters, two comparators, and a Peripheral Pin Select that remaps most digital peripherals to any of the 100 pins. The integrated CTMU enables capacitive touch sensing for buttons, sliders, and proximity detection without external components. The MIPS32 M4K core delivers 1.56 DMIPS/MHz and supports the MIPS16e instruction set for 40% code compression, freeing Flash for application code. Hardware Multiply/Divide unit executes 32x32 in one cycle. Single-cycle Flash access delivers deterministic performance at 50 MHz, with zero-wait-state execution from Flash prefetch cache. Compared to Cortex-M0+ parts at the same frequency, the PIC32MX170 offers substantially more SRAM and richer peripherals at modest power. Typical applications include automotive HMI clusters, USB audio bridges, CAN-connected industrial sensors, graphic LCD controllers with PMP, capacitive touch user interfaces, and USB-CAN gateways. The AEC-Q100 qualification makes the -V (automotive) grade suitable for in-cabin automotive modules. Design consideration: the PPS feature requires configuration via SFR writes at startup before the remapped peripherals operate, so initialize PPS in the first lines of main(). Decoupling requires 0.1 uF and 10 uF capacitors close to each VDD/VSS pair; the device has multiple VDD/VSS pins across the 100-TQFP layout.
