PIC32MX170F256DT-I/TL - 32-bit MCU, 256KB Flash, 44-VTLA | Microchip
The Microchip Technology PIC32MX170F256DT-I/TL is a 32-bit MIPS32 M4K microcontroller operating at 40 MHz with 256 KB Flash and 64 KB SRAM, packaged in a 44-pin VTLA (6x6 mm) surface-mount module. The device integrates USB 2.0 full-speed, audio I2S, 10-bit ADC, and up to 35 I/O pins in a compact thermally-enhanced leadless footprint designed for space-constrained embedded designs.
A PIC32MX 32-bit microcontroller is a high-performance MIPS-based MCU family from Microchip that combines deterministic real-time control with rich peripherals (USB, I2S, CAN) and large unified memory, bridging the gap between 8/16-bit PIC MCUs and higher-end ARM Cortex-M parts. The PIC32MX1xx/2xx family targets cost-sensitive audio, USB-device, graphical, and general-purpose embedded designs, sitting in the broader hierarchy of 32-bit MCU -> embedded controller -> semiconductor device.
Key features of the PIC32MX170F256DT-I/TL include 256 KB (256K x 8) Flash, 64 KB SRAM, 35 programmable I/O, a 10-bit ADC with up to 28 input channels, USB 2.0 full-speed OTG, I2S audio interface, four I2C and five UART peripherals, and a wide operating voltage range of 2.3 V to 3.6 V. The 40 MHz core delivers 1.56 DMIPS/MHz (Dhrystone 2.1) of compute, while MIPS16e instruction mode reduces code footprint by approximately 40% for memory-constrained applications.
The device uses a 5-stage pipeline Harvard architecture with separate 16 KB instruction and 16 KB data caches prefetch buffer to maximize sustained throughput from Flash. An integrated 8 MHz internal RC oscillator with PLL enables up to 40 MHz system clock, and multiple low-power modes (Sleep, Idle, Deep Sleep with RTC) allow typical Sleep currents in the tens of microamp range for battery-friendly designs. Hardware DMA on USB, I2S, ADC, and UART peripherals offloads data movement from the CPU.
Typical applications include USB audio devices, low-cost graphical LCD/HMI controllers, sensor aggregation nodes, USB HID peripherals, and industrial control front-ends. The combination of USB, I2S, and 35 I/O makes the part well-suited to bridge legacy peripherals and a modern host. For automotive, medical, or safety-critical use, consult the PIC32MX family errata and consider PIC32MK or dsPIC33 variants instead.
When designing with this device, ensure the 44-VTLA (TL) land pattern matches the thermal pad of your PCB: missing the exposed pad connection will derate power dissipation significantly. Use MPLAB Harmony or MPLAB X IDE projects configured for PIC32MX170F256D family; the "T" suffix indicates Tape and Reel packaging, while "I" denotes the -40 C to +85 C industrial temperature range.
