With 62 general-purpose I/O lines, this MCU suits human-machine interface and sensor-fusion applications. ## Memory and data converter headroom The 128 KB flash and 32K x 8 RAM provide enough headroom for a real-time control loop with a modest GUI stack. The 2K x 8 EEPROM stores calibration constants or configuration parameters without wearing the flash. Data converters include two 12-bit ADCs and four 8-bit DACs, covering analog front-end and signal-generation tasks without an external converter. The 100-TQFP (14x14 mm) package has a 0.5 mm pitch — a four-layer PCB with via-in-pad is typical for fan-out. Production status is active, and the part is ROHS3 compliant.","metaTitle":"CY8C5667AXI-LP006 Infineon MCU, 67MHz, 128KB Flash, 100-TQFP","metaDescription":"Infineon CY8C5667AXI-LP006 ARM Cortex-M3 MCU, 67MHz, 128KB Flash, 32K x 8 RAM, 2K x 8 EEPROM, 62 I/O, -40 to 85°C.
