The 10 KB RAM limits buffering, so keep packet sizes tight. ## Memory mix: Flash, RAM, and EEPROM The 32 KB Flash holds the application image; the 4 KB EEPROM stores calibration constants, serial numbers, or last-state logs that survive a power cycle. The 10 KB RAM is shared between stack, heap, and global variables — enough for a Modbus RTU slave or a simple PID loop, but a graphics frame buffer or large lookup table will push the limit. Plan the memory map early.","metaTitle":"NXP LPC11E14FBD64/401,551 ARM Cortex-M0 MCU, 50 MHz","metaDescription":"NXP LPC11E14FBD64/401,551 32-bit ARM Cortex-M0 MCU, 50 MHz, 32 KB Flash, 10 KB RAM, 4 KB EEPROM, 54 I/O, -40 to 85 °C, 64-LQFP.
