PIC32MX170F256DT-50I/TL

PIC32MX170F256DT-50I/TL - 50MHz 32-bit MCU 256KB Flash | Microchip

The Microchip Technology PIC32MX170F256DT-50I/TL is a 32-bit PIC microcontroller built on the MIPS32 M4K core, delivering 50 MHz (83 DMIPS) performance with 256 KB Flash and 64 KB SRAM in a 44-pin VTLA (6x6 mm) surface-mount package. It integrates a 10-bit 1 Msps ADC, USB 2.0 full-speed device/host/OTG, I2S audio interfaces, and a Parallel Master Port (PMP) for graphics, targeting embedded applications that require USB connectivity, audio processing, or graphical LCD control. What is a PIC32MX microcontroller? The PIC32MX family is Microchip's MIPS-based 32-bit extension of the legacy PIC16/PIC24 16-bit portfolio, positioned in the mid-range embedded segment between 8-bit AVR/PIC MCUs and higher-end ARM Cortex-M parts. It runs the same MPLAB Harmony and MPLAB X toolchains as Microchip's other MCUs, giving designers an upgrade path from 8-bit code while keeping the same peripheral libraries and debugger ecosystem. Within the PIC32MX1xx/2xx 44-pin sub-family, the PIC32MX170 specifically adds USB and advanced analog, while the PIC32MX150 in the same pinout drops USB. Key features include 256 KB single-cycle Flash, 64 KB SRAM, Peripheral Pin Select (PPS) for flexible signal routing, mTouch capacitive touch support, a 1 ns resolution 16-bit timer/capture engine, and on-chip temperature sensing. Six UART, four SPI, and four I2C channels give generous connectivity headroom for sensor hubs, while the hardware crypto block is absent on the MX1xx series (unlike MX2xx). The device operates from 2.3 V to 3.6 V. 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.

PIC32MX170F512HT-50I/MR

PIC32MX170F512HT-50I/MR - 50MHz 32-bit MCU, 512KB Flash | Microchip

The Microchip PIC32MX170F512HT-50I/MR is a 32-bit MIPS microcontroller built on the MIPS32 M4K core, operating at up to 50 MHz/83 DMIPS, with 512 KB Flash and 64 KB RAM in a 64-pin QFN (MR) 9x9 mm package with industrial -40C to +85C temperature grade. A 32-bit microcontroller (MCU) is a programmable system-on-chip that integrates a processor core, program memory, data memory, and peripherals into a single IC. PIC32MX MCUs sit in Microchip's mid-range 32-bit portfolio, sitting below the Cortex-M class for low-power connected designs and above the 8-bit PIC16/PIC18 families for computationally demanding real-time control. As a member of the PIC32 family, the PIC32MX170F512H falls within the PIC32MX1x0/2x0 superset of low-cost, USB-optional 32-bit parts. Key features of the PIC32MX170F512HT-50I/MR include 50 MHz CPU clock (83 DMIPS) with single-cycle 32x16 MAC and two-cycle 32x32 hardware multiply, 16-channel 10-bit ADC at up to 1 Msps, four SPI modules, two I2S interfaces for codec audio, two I2C, five UART modules, two comparators, CTMU for touch and capacitive sensing, PMP with dual read/write buffers for graphics, and Peripheral Pin Select (PPS) for flexible signal routing. The 512 KB Flash supports 10,000 minimum erase/write cycles and the device supports MIPS16e code compression for up to 40% smaller code. Architecturally, the PIC32MX170F512H uses the MIPS M4K Harvard architecture with separate 32-bit instruction and data buses, 5-stage pipeline, hardware multiply/divide, and an integrated prefetch cache that boosts Flash throughput. The Peripheral Pin Select (PPS) remapping block decouples digital peripheral I/O from physical pin assignments, which is rare at this price point and dramatically simplifies PCB layout revisions. The 64-pin QFN (MR) package exposes a large EP thermal pad for low-thermal-resistance dissipation. Typical applications include industrial control and HMI panels, USB device/embedded host peripherals, low-cost graphics with PMP-driven TFT displays, audio processing with external I2S codecs, capacitive touch user interfaces using the CTMU, sensor aggregation nodes, and home appliance motor control. The wide peripheral set makes it suitable as a main MCU for connected consumer devices and IoT edge nodes. When designing with this device, reserve at least one PGECx/PGEDx pair for in-circuit serial programming (ICSP) and connect all VSS/VDD pairs to a low-impedance ground/power plane. The PPS remapping block must be unlocked via CFGCON before remapping - leaving defaults active is the most common debug pitfall on first hardware bring-up. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes for the PIC32MX170F512HT-50I/MR that are not found in the manufacturer datasheet alone.

PIC32MX170F512HT-50I/PT

PIC32MX170F512HT-50I/PT - 50MHz 32-bit MCU 512KB Flash TQFP-64

The Microchip Technology PIC32MX170F512HT-50I/PT is a 32-bit MIPS M4K microcontroller operating up to 50 MHz (83 DMIPS), integrating 512 KB Flash and 64 KB SRAM, and offered in a 64-pin TQFP (PT) package with industrial -40C to +85C temperature rating. The "T" suffix indicates tape-and-reel packaging for high-volume SMT assembly. The part delivers deterministic real-time performance with 5-stage pipeline M4K core, Peripheral Pin Select (PPS) for flexible pin mapping, and a Parallel Master Port (PMP) for graphics interfaces. A 32-bit microcontroller (MCU) is a single-chip computer integrating a high-performance processor core (here MIPS M4K), Flash program storage, SRAM data memory, and rich peripherals (UART, I2C, SPI, ADC, timers, USB, CAN). Microcontrollers sit within the embedded systems / semiconductor hierarchy: MCU -> embedded processor -> IC -> semiconductor device. The PIC32MX1xx family specifically targets applications needing USB 2.0 Full-Speed OTG, audio (I2S), and graphics PMP interfaces while retaining low power and deterministic interrupt response. Key features include two I2S modules for audio codec interfacing, a 10-bit 1 Msps ADC with up to 28 channels, four SPI modules for high-throughput peripherals, five 16-bit timers, a real-time clock calendar, and an integrated USB 2.0 Full-Speed OTG controller with dedicated DMA. The PIC32MX170F512HT-50I/PT also supports JTAG and 2-wire ICSP debugging, and operates from 2.3V to 3.6V. The M4K core implements a 5-stage pipeline with single-cycle multiply and hardware divide, and the MMU-less architecture simplifies deterministic embedded firmware. The 512 KB Flash supports eXtreme Switch (XLP) low-power modes and In-Circuit Serial Programming (ICSP) for field upgrades. Typical applications include USB peripherals (Human Interface Devices, CDC serial, audio), industrial control with PMP-driven character or graphic LCDs, multi-sensor data acquisition hubs, and consumer audio docks. The high DMIPS/MHz ratio and rich connectivity make the part suited for protocols requiring real-time response such as Modbus, CAN-based industrial nodes (with external PHY), and USB stacks. Design considerations: the PT package exposes all 64 pins including full JTAG, PGECx/PGEDx pairs (multiple), and five VDD/VSS pairs. Decouple each VDD pin with a 100 nF ceramic placed within 5 mm. The USB D+/D- lines require 90 ohm differential impedance with ESD protection (e.g., USBLC6-2). PPS reassignment must respect peripheral-to-pin mapping tables in the datasheet. This page synthesizes distributor pricing, drop-in alternatives drawn from the PIC32MX1xx family, and 3 practical design notes that complement but are not redundant with the manufacturer datasheet.
