It integrates CapSense capacitive touch sensing, LCD segment drive, and a full set of programmable analog and digital blocks — the hallmark of the PSoC architecture. The part is aimed at human-machine interface (HMI) applications such as touch-button panels, capacitive sliders, and simple graphic displays in industrial control panels, white goods, and building automation. The 48 MHz clock is fast enough to handle real-time capacitive scanning, LCD refresh, and communication protocol stacks without a separate co-processor. The 32 KB Flash and 4 KB SRAM are sized for moderate firmware loads — think a touch-sensor firmware with a few hundred lines of state-machine logic, not a full RTOS with a TCP/IP stack. ## 1.71 V to 5.5 V supply — single-rail or battery operation The supply range spans 1.71 V to 5.5 V. The internal oscillator and brown-out detect circuitry keep the core stable across the full range. ## Industrial temperature grade — -40°C to 85°C Rated for -40°C to 85°C ambient, the CY8C4245AZI-483 suits outdoor telecom cabinets, unheated factory floors, and automotive cabin modules. The 48-LQFP package (7x7 mm body) is a standard footprint for hand-assembly and reflow, with 36 general-purpose I/O brought out. ## Active lifecycle — no end-of-life risk for new designs The part carries an Active lifecycle status, meaning Infineon continues to manufacture it without a planned discontinuation. For BOM planning, this removes the single-source risk that comes with NRND or EOL parts.","metaTitle":"CY8C4245AZI-483 PSoC 4 MCU, ARM Cortex-M0, 48 MHz","metaDescription":"Infineon CY8C4245AZI-483 PSoC 4 MCU: ARM Cortex-M0 at 48 MHz, 32 KB Flash, 4 KB SRAM, CapSense, LCD drive, 1.71 V to 5.5 V supply, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"PSOC® 4 CY8C42xx","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Speed":"48MHz","Series":"PSOC® 4 CY8C42xx","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":"36","Core Processor":"ARM® Cortex®-M0","Package / Case":"48-LQFP","Data Converters":"A/D 8x12b SAR; D/A 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":"$5.3","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.30000","currency":"USD"},{"qty":10,"price":"$4.76000","currency":"USD"},{"qty":25,"price":"$4.49960","currency":"USD"},{"qty":80,"price":"$3.89963","currency":"USD"},{"qty":250,"price":"$3.69964","currency":"USD"},{"qty":500,"price":"$3.31966","currency":"USD"},{"qty":1000,"price":"$2.79972","currency":"USD"},{"qty":2500,"price":"$2.65974","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e5f484480ae4d569e929a84cc6cbf381.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does the CY8C4245AZI-483 support CapSense?","answer":"Yes, CapSense is listed among the integrated peripherals.
