LPC5411x
32-bit ARM Cortex-M4/M0+ microcontroller
11.10 SPI interfaces
The actual SPI bit rate depends on the delays introduced by the external trace, the
external device, system clock (CCLK), and capacitive loading. Excluding delays
introduced by external device and PCB, the maximum supported bit rate for SPI master
mode is 48 Mbit/s, and the maximum supported bit rate for SPI slave mode is 15 Mbit/s.
