Key Features
- 32-bit MIPS-based PIC32MX core clocked up to 50 MHz, delivering high computational throughput for real-time control and signal processing in a SOIC-28 package
- 256 KB program flash plus 12 KB dedicated boot flash and DMA channels for efficient background data transfers without CPU overhead
- Integrated ADC and broad peripheral set including timers, UART, SPI, and I2C, enabling single-chip solutions for sensor acquisition and communication interfaces
Applications
The PIC32MX174F256B-I/SO suits industrial HMI panels, smart metering terminals, and handheld test instruments that need 32-bit compute power within the familiar SOIC-28 footprint. Its DMA engine offloads bulk data movement from the CPU, making it effective for data-logging applications that continuously stream sensor readings to external memory or wireless modules. With 256 KB of flash, designers can store complex firmware stacks including USB, TCP/IP, or graphics libraries in a single cost-effective package.

Frequently Asked Questions
What maximum clock frequency does the PIC32MX174F256B-I/SO support, and how does this affect real-time task throughput?
The PIC32MX174F256B-I/SO runs at up to 50 MHz on its 32-bit MIPS core, delivering up to 50 DMIPS of processing performance. This throughput is sufficient for real-time PID control loops, UART-based logging at 115200 baud, and concurrent ADC sampling without requiring an external coprocessor.
How can the DMA channels in PIC32MX174F256B-I/SO improve data-logging system designs?
The DMA controller allows the PIC32MX174F256B-I/SO to transfer ADC sample buffers or SPI data streams to external SRAM or flash without stalling the CPU at 50 MHz. In a data-logging design, 8 or more channels can be sampled continuously at multi-kHz rates while the CPU processes earlier blocks, reducing latency and power consumption compared to interrupt-driven transfers.
What lead time and package should procurement teams plan for when sourcing PIC32MX174F256B-I/SO?
The PIC32MX174F256B-I/SO is supplied in a 28-pin SOIC package with a 6-week factory lead time from Microchip. Procurement teams should confirm reel quantities with distributors at least 8 weeks before production to account for shipping and incoming inspection, especially given the 18-year estimated time to end-of-life for long-term program planning.
