Product data sheet Rev. 1.9 — 10 February 2020 86 of 128 NXP Semiconductors LPC55S6x 32-bit ARM Cortex-M33 microcontroller 11.9 I2S-bus interface [1] Based on simulation; not tested in production. [2] Clock Divider register (DIV) = 0x0. [3] Typical ratings are not guaranteed. [4] The Flexcomm Interface function clock frequency should not be above 48 MHz. See the data rates section in the I2S chapter (UM11126) to calculate clock and sample rates. [5] Based on simulation. Not tested in production. Table 31. Dynamic characteristics: I2S-bus interface pins [1][4] Tamb = 40 C to 105 C; VBAT_DCDC = 1.8 V to 3.6 V; CL = 10 pF balanced loading on all pins; Input slew = 1.0 ns, SLEW setting = standard mode for all pins; Parameters sampled at the 50% level of the rising or falling edge.
