It carries 512 KB of Flash program memory, 128 KB of RAM, and a useful 16 KB of EEPROM on-chip — that last item saves you an external serial EEPROM on the BOM. ## 120 MHz Cortex-M4 — what that means for throughput The 120 MHz core handles real-time control loops and moderate DSP tasks without a separate coprocessor. ## Memory map and the EEPROM advantage The 128 KB RAM supports double-buffered data acquisition or a small display frame buffer. The 16 KB EEPROM is the standout: it is true EEPROM, not emulated Flash, so you can write single bytes without erase cycles. That saves an external 24LCxx part and the I²C traffic. For calibration constants or fault logs that get written thousands of times, this is the right part. ## Supply voltage and power domains","metaTitle":"NXP MK20FX512VLQ12 Kinetis K20 MCU, ARM Cortex-M4 120MHz","metaDescription":"MK20FX512VLQ12 Kinetis K20 32-bit MCU with 512KB Flash, 128KB RAM, 16KB EEPROM, 120MHz Cortex-M4, 144-LQFP, -40 to 105°C.
