Product details

Dual-core architecture — asymmetric processing without the power penalty

The NXP LPC54102J512BD64151 pairs a 100 MHz ARM Cortex-M4 with a Cortex-M0+ on the same die, splitting DSP-capable compute from background housekeeping. The M4 handles sensor fusion, audio processing, or control loops while the M0+ manages I²C/SPI/UART traffic, wake-up logic, and power-state transitions. This asymmetric dual-core approach lets the M4 sleep during light loads, drawing only the M0+ current, which keeps the active power profile lower than a single-core part at equivalent throughput.

Memory and I/O budget for BOM fit

512 KB Flash and 104 KB RAM support firmware with a real-time OS and sensor libraries. The 50 GPIOs and 12-channel 12-bit ADC cover mixed-signal interfaces without an external mux.

Frequently asked questions

Does LPC54102J512BD64151 have dual-core ARM Cortex-M4 and M0+?

Yes, it integrates a 100 MHz ARM Cortex-M4 and a Cortex-M0+ on a single die, enabling asymmetric processing where the M4 handles compute-intensive tasks and the M0+ manages I/O and power states.

What is the pinout of LPC54102J512BD64151?

The pinout follows the standard 64-LQFP (10x10 mm) assignment for the LPC54100 series. The supplier device package is 64-LQFP (10x10). For exact pin functions and alternate configurations, refer to the NXP LPC5410x user manual.

What is the difference between LPC54102 and LPC54114?

The LPC54114 is a higher-density variant with 256 KB Flash and 256 KB RAM, compared to the LPC54102's 512 KB Flash and 104 KB RAM. Both share the same 64-LQFP footprint, dual-core architecture, and peripheral set, making the LPC54114 a drop-in upgrade for designs requiring more RAM.
