It comes in a 24-QFN package with exposed pad, offering 20 GPIOs. ## I²C-only serial interface — design-in constraint vs. richer siblings Unlike the CY8C4245LQI-483 which adds SPI, UART/USART, IrDA, LINbus, and SmartCard interfaces, the CY8C4014LQI-422T is limited to I²C for serial communication. This makes it a fit for simple sensor aggregation, I²C bus extenders, or single-protocol control nodes, but not for designs needing UART debug output or SPI flash expansion without bit-banging GPIO. However, the part is listed as RoHS non-compliant, which may restrict its use in markets with strict RoHS enforcement or require an exemption declaration.","metaTitle":"CY8C4014LQI-422T PSoC 4 MCU, ARM Cortex-M0, 16 MHz","metaDescription":"Cypress CY8C4014LQI-422T 32-bit ARM Cortex-M0 MCU, 16 MHz, 16 KB Flash, 2 KB RAM, 1.71V–5.5V, -40°C to 85°C, 24-QFN.","metaKeywords":null},"attributes":{"series":"PSOC® 4 CY8C4000","packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Speed":"16MHz","Series":"PSOC® 4 CY8C4000","Package":"Tape & Reel (TR)","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":"20","Core Processor":"ARM® Cortex®-M0","Package / Case":"24-UFQFN Exposed Pad","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 ~ 85°C (TA)","Supplier Device Package":"24-QFN (4x4)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.8","stockQuantity":0,"priceTiers":[{"qty":400,"price":"$1.30000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7fc595c79bf74a5401fdaacbab41e60e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is CY8C4014LQI-422T's listed speed?","answer":"The CY8C4014LQI-422T is rated for a 16 MHz core speed, which is appropriate for low-power sensor polling, I²C bridge tasks, and simple control loops rather than high-throughput signal processing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY8C4014LQI-422T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY8C4014LQI-422T when reusing this data.
