Core and memory for sensor-front-end control
The CY8C4025AZI-S403: The 32 KB on-chip flash and 4 KB RAM give enough headroom for a CapSense touch interface, a few serial sensor streams, and a PID loop without external memory.
Integrated peripherals shrink the BOM
The LCD drive peripheral can run a segment display without an external driver IC. Brown-out detect, low-voltage detect, and POR keep the reset logic clean on a noisy 1.71 V to 5.5 V rail. Serial connectivity covers I²C, SPI, UART, LINbus, IrDA, Microwire, SmartCard, and SSP — enough to talk to a MEMS accelerometer, a temperature sensor, and a motor driver over a single bus.
Industrial temperature and active lifecycle
The 48-TQFP (7x7 mm) package is rework-friendly with standard hot-air profiles — no underfill needed for most applications.
