The LPC2148 family shares the same ARM7 core and 100-LQFP package but has different memory sizes and adds USB; verify pin compatibility against your board before substituting."},{"question":"What is the pinout of LPC2157FBD100,551?","answer":"The pinout follows the standard 100-LQFP ARM7 mapping for the LPC2100 series. The 38 I/O lines, ADC inputs, and serial interface pins are assigned per the NXP datasheet; the internal oscillator uses the XTAL1/XTAL2 pins if an external crystal is desired."},{"question":"Is LPC2157FBD100,551 equivalent to LPC2148?","answer":"Both are ARM7 MCUs in 100-LQFP packages, but the LPC2148 includes USB 2.0 Full Speed and typically has different memory sizes.
