Product details

At 72 MHz the ARM Cortex-M3 core executes single-cycle multiply and hardware divide, which matters for PID loops, encoder interpolation, and Modbus CRC calculation. The 12-bit ADC samples eight channels sequentially; at this clock rate the conversion time stays under 3 µs per channel, adequate for current-sense feedback in motor drives or pressure-transducer readout in industrial panels.

Supply range 2 V to 3.6 V; internal POR and brown-out detect reset the core on power-up and during supply dips.

Serial interface mix and I/O allocation

Connectivity includes I²C, SPI, SSP, UART/USART, and Microwire. 40 I/O lines multiplexed with these peripherals.

Active product status from NXP. ROHS3 compliant.

Frequently asked questions

What is the LPC1317FBD48,551's core speed?

The ARM Cortex-M3 core runs at 72 MHz. That places it in the mid-range of the LPC13xx family, suitable for control loops and protocol handling that need deterministic timing.

What compliance documentation does NXP provide for LPC1317FBD48,551?

The part is ROHS3 compliant. NXP typically provides a RoHS certificate of compliance and material declaration upon request through the supply chain.

What is the closest pin-compatible alternative to LPC1317FBD48,551?

Within the LPC13xx series, the LPC1317 is part of a pin-compatible density family. Higher-Flash siblings (e.g., LPC1347 with 64 KB Flash and USB) share the same 48-LQFP footprint and pinout, allowing a BOM swap without board re-spin if more memory or USB connectivity is needed.
