67 MHz Cortex-M3 with on-chip CapSense and USB
The CY8C5667AXI-LP006 is an ARM Cortex-M3 MCU running at 67 MHz, part of the PSOC 5 CY8C56LP family. 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.
