The 16 MHz core can handle a 100 kHz I²C bus without wait-state bottlenecks, but the 2 KB SRAM limits buffering to a few hundred bytes of payload. ## Supply voltage and temperature grade No AEC-Q100 qualification is listed, so this part is not certified for automotive safety or powertrain applications. ## On-chip peripherals reduce external parts count Brown-out detect, power-on reset, a watchdog timer, and a PWM block are integrated on die. For a simple control loop — reading a hall-effect sensor over I²C and driving a PWM fan output — the CY8C4013SXI-400 needs no external supervisor IC, reset generator, or timer chip. The brown-out threshold is fixed; the datasheet reset voltage is not user-programmable, so the supply must stay above the dropout level during operation. ## Active lifecycle and compliance The part is ROHS3 compliant, covering all ten restricted substances including the four phthalates added in EU 2015/863.","metaTitle":"CY8C4013SXI-400 Infineon PSoC 4 MCU, 16 MHz, 8-SOIC","metaDescription":"CY8C4013SXI-400 Infineon PSoC 4 ARM Cortex-M0 MCU, 16 MHz, 8 KB Flash, 2 KB RAM, 8-SOIC, -40°C to +85°C.
