The part is ROHS3 compliant, which aligns with current European and Asian regulatory requirements for new equipment. ## 48-TQFP package and 38 I/O — board layout considerations Housed in a 48-TQFP (7x7 mm) with 38 general-purpose I/O, this package is a standard fine-pitch QFP that routes easily on two-layer boards. The 38 I/O count includes the CapSense pins, which need clean routing away from switching nodes to maintain touch sensitivity.","metaTitle":"Infineon CY8C4125AZI-M433 PSoC 4 MCU, ARM Cortex-M0, 24 MHz","metaDescription":"Infineon CY8C4125AZI-M433 is a 32-bit ARM Cortex-M0 PSoC 4 MCU with 32 KB Flash, 4 KB SRAM, CapSense, 16ch 12-bit ADC, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"PSOC® 4 CY8C41xx - M","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Speed":"24MHz","Series":"PSOC® 4 CY8C41xx - M","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":"38","Core Processor":"ARM® Cortex®-M0","Package / Case":"48-LQFP","Data Converters":"A/D 16x12b SAR; 2xIDAC","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":"48-TQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.69","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.69000","currency":"USD"},{"qty":10,"price":"$3.31700","currency":"USD"},{"qty":25,"price":"$3.13600","currency":"USD"},{"qty":80,"price":"$2.71788","currency":"USD"},{"qty":250,"price":"$2.57852","currency":"USD"},{"qty":500,"price":"$2.31370","currency":"USD"},{"qty":1000,"price":"$1.95132","currency":"USD"},{"qty":2500,"price":"$1.85375","currency":"USD"},{"qty":5000,"price":"$1.78406","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c73526f7928ad498916174d427c0e08f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY8C4125AZI-M433 compatible with PSoC Creator?","answer":"Yes, as a PSoC 4 family member, the CY8C4125AZI-M433 is supported in Infineon's PSoC Creator IDE, which provides graphical configuration for the CapSense, ADC, and digital peripherals.

It runs at 48 MHz (vs. 24 MHz) and comes in a 48-QFN package instead of TQFP. While not pin-compatible, it shares the same software architecture and can serve as a performance upgrade path if the design can accommodate the QFN footprint."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY8C4125AZI-M433","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY8C4125AZI-M433 when reusing this data.
