您好，
请就 LPC17xx 系列的精确引脚对引脚替换提出建议。
我有现有的设计，修改硬件是个问题，但我有很多使用 LPC2148 外围设备（UART、I2C、计时器等）的代码（很多），哪个新系列与外设软件兼容？
建议用于新设计的哪个系列具有大致相当的能力（内存大小、速度、外设等）？
我也有同样的问题，而且现在已经过去快 5 年了。
新设计应该使用哪个系列的微控制器？
HI
LPC1768 是 LPC2368 的替代品。而 LPC1769 则是 LPC1768 的替代品。唯一不同的是最大时钟频率（120Mhz）。内存较少的替代品是LPC1766。LPC4078是更换LPC176x的选项。(http://www.nxp.com/products/microcontrollers/core/cortex_m4_m4f/LPC4078FBD100.html)
请注意，LPC4078 的版本时间为 2013 年，寿命为 15 年。
LPC546xx 和 LPC540xx 不是 LPC17xx 的引脚对引脚替代品
祝您愉快
张俊
