The LPC55 sub-family varies primarily by core count, memory density, and peripheral sets. 'S6x' variants feature dual-core Cortex-M33 configurations for maximum performance, while 'S2x' and 'S1x' models offer single-core efficiency. Package options range from 64-pin HTQFP to 100-pin HLQFP and VFBGA98, directly impacting available I/O count. Security features like TrustZone and the PRINCE encryption engine are standard across the 'S' designated parts.
