Brown-out detect, POR, and LVD are on-chip, so external reset supervisors are unnecessary. The 32-QFN with exposed pad (5x5 mm) helps pull heat out through the PCB ground plane — critical if the MCU is running near the top of the temperature range with several I/O pins switching. ## CapSense and 27 I/O — touch interface without an external controller The built-in CapSense peripheral handles capacitive touch buttons, sliders, and proximity sensors directly, eliminating a dedicated touch controller from the BOM. With 27 general-purpose I/O, there are enough pins to run a small character LCD, a few LEDs, and a serial link alongside the touch electrodes. The PSoC 4 family has broad distributor coverage; second-source equivalents are not officially listed, but the pin-compatible CY8C4245LQI-483 (48 MHz, 8x12-bit ADC, 34 I/O) is a drop-in upgrade path if the design later needs more throughput or analog channels.","metaTitle":"CY8C4025LQI-S412 PSoC 4 MCU, 24 MHz ARM Cortex-M0+","metaDescription":"Infineon CY8C4025LQI-S412 is a 32-bit ARM Cortex-M0+ MCU with 24 MHz core, 32 KB Flash, 4 KB RAM, CapSense, wide 1.71V-5.5V supply, industrial -40°C to 85°C","metaKeywords":null},"attributes":{"series":"PSOC® 4 CY8C4000S","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Speed":"24MHz","Series":"PSOC® 4 CY8C4000S","Package":"Tray","RAM Size":"4K x 8","Core Size":"32-Bit Single-Core","Peripherals":"Brown-out Detect/Reset, CapSense, LCD, LVD, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, Microwire, SmartCard, SPI, SSP, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"27","Core Processor":"ARM® Cortex®-M0+","Package / Case":"32-UFQFN Exposed Pad","Data Converters":"A/D 1x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"32-QFN (5x5)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.24","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.24000","currency":"USD"},{"qty":10,"price":"$2.90900","currency":"USD"},{"qty":25,"price":"$2.74960","currency":"USD"},{"qty":80,"price":"$2.38313","currency":"USD"},{"qty":230,"price":"$2.26087","currency":"USD"},{"qty":490,"price":"$2.02869","currency":"USD"},{"qty":980,"price":"$1.71094","currency":"USD"},{"qty":2450,"price":"$1.62539","currency":"USD"},{"qty":4900,"price":"$1.56429","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a3c4c8787d664729a6e0a4fe3d8b4319.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does CY8C4025LQI-S412 have built-in CapSense?","answer":"Yes, CapSense is one of the integrated peripherals, along with brown-out detect, LCD drive, LVD, POR, PWM, and WDT."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY8C4025LQI-S412","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY8C4025LQI-S412 when reusing this data.
