LPC3220、LPC3230、LPC3240、LPC3250数据手册据The LPC3220/30/40/50 embedded microcontrollers were designed for low power, highperformance applications. NXP achieved their performance goals using a 90 nanometerprocess to implement an ARM926EJ-S CPU core with a vector floating point co-processorand a large set of standard peripherals including USB On-The-Go. TheLPC3220/30/40/50 operates at CPU frequencies of up to 266 MHz.
