A single I²C interface provides connectivity to sensors, EEPROMs, or a body-controller module. ## Temperature grade and package — built for under-hood and cabin The 16 KB Flash and 2 KB RAM are sized for control-oriented firmware: reading a temperature sensor over I²C, driving a PWM fan or pump, and managing a watchdog timeout. The 7-bit and 8-bit DAC outputs can generate analog setpoints or simple waveforms without an external DAC.","metaTitle":"CY8C4014SXS-421Z PSoC 4 MCU, 16 MHz, 16 KB Flash, AEC-Q100","metaDescription":"Infineon CY8C4014SXS-421Z 32-bit ARM Cortex-M0 MCU, 16 MHz, 16 KB Flash, 2 KB RAM, -40°C to 105°C, AEC-Q100, 16-SOIC.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100, PSOC® 4 CY8C4000","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Speed":"16MHz","Series":"Automotive, AEC-Q100, PSOC® 4 CY8C4000","Package":"Tube","RAM Size":"2K x 8","Core Size":"32-Bit Single-Core","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C","Mounting Type":"Surface Mount","Number of I/O":"13","Core Processor":"ARM® Cortex®-M0","Package / Case":"16-SOIC (0.154\\\", 3.90mm Width)","Data Converters":"D/A 1x7b, 1x8b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"16KB (16K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"16-SOIC","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.88","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.88000","currency":"USD"},{"qty":10,"price":"$4.38500","currency":"USD"},{"qty":25,"price":"$4.14520","currency":"USD"},{"qty":100,"price":"$3.59240","currency":"USD"},{"qty":250,"price":"$3.40816","currency":"USD"},{"qty":500,"price":"$3.05812","currency":"USD"},{"qty":1000,"price":"$2.57914","currency":"USD"},{"qty":2500,"price":"$2.45018","currency":"USD"}]},"links":{"datasheetUrl":"https://www.cypress.com/file/139976/download","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional second-source for CY8C4014SXS-421Z?","answer":"The CY8C4245LQI-483 is a higher-performance PSoC 4 sibling with a 48 MHz core, more I/O (34), and additional connectivity (SPI, UART, LINbus), but it comes in a 40-QFN package and has a narrower temperature range (85°C).
