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.","metaTitle":"CY8C4025AZI-S403 Infineon PSOC 4 MCU, 32KB Flash, 48-TQFP","metaDescription":"CY8C4025AZI-S403 Infineon PSOC 4 MCU, 32-bit ARM Cortex-M0+ at 24 MHz, 32KB flash, 4KB RAM, 36 I/O, 48-TQFP.
