What is the recommended microcontroller series that replaces the LPC1768 series?

Hi,

Anyone please suggest exact pin to pin replacement for LPC17xx series.

I have existing designs, modify hardware is a problem, but I have a lot of code (tons) using LPC2148 peripherals (UART, I2C, Timers, ...), which new family is peripheral-software compatible?.

What series recommended for new designs has roughly equivalent capability (Memory size, speed, peripherals, etc.)?

the LPC1768 is a replacement for the LPC2368. and the LPC1769 is a replacement for the LPC1768. The only difference is the max clock frequency (120Mhz) . A replacement with less memory is the LPC1766.LPC4078 is an option for LPC176x replacement.(http://www.nxp.com/products/microcontrollers/core/cortex_m4_m4f/LPC4078FBD100.html )
Please note LPC4078 release time is 2013, 15 years longevity.

Our Recommendation is LPC546xx or LPC540xx MCUs series, based on Cortex M4 core at 220MHz (with optional secondary Cortex M0+ core), similar peripherals, up to 512KB Flash and up to 200KB RAM.Please check more information in the following link:https://www.nxp.com/products/processors-and-microcontrollers/arm-based-processors-and-mcus/lpc-cortex-m-mcus/lpc54000-series-cortex-m4-mcus:MC_1414576688124

LPC546xx and LPC540xx are not pin to pin replacement of LPC17xx

Have a nice day,

I have the same question, and appreciate it's now almost 5 years later.

Which series of microcontrollers should I be looking at to use for new designs?
