Product data sheet Rev. 3 — 29 July 2013 49 of 71 NXP Semiconductors LPC81xM 32-bit ARM Cortex-M0+ microcontroller 12.6 SPI interfaces The maximum data bit rate is 30 Mbit/s in master mode and 25 Mbit/s in slave mode. Remark: SPI functions can be assigned to all digital pins. The characteristics are valid for all digital pins except the open-drain pins PIO0_10 and PIO0_11. [1] Capacitance on pin SPIn_SCK CSCK < 5 pF. [2] Tcy(clk) = DIVVAL/CCLK with CCLK = system clock frequency. DIVVAL is the SPI clock divider. See the LPC800 User manual UM10601. Table 17. SPI dynamic characteristics Tamb = 40 C to 105 C; 1.8 V <= VDD <= 3.6 V. Simulated parameters sampled at the 50 % level of the rising or falling edge; values guaranteed by design.
