It has 32 KB of Flash program memory and 4K x 8 of SRAM. ## CapSense and LCD drive — what it saves on the BOM The on-chip CapSense peripheral handles capacitive touch buttons, sliders, and proximity sensing without an external controller IC. The LCD drive supports direct connection to segment LCD glass, removing the need for a dedicated display driver. For a control panel with a small LCD and capacitive touch, this part can replace two external ICs plus their supporting passives — a meaningful cost and space saving on a compact 24-QFN (4x4 mm) board. ## Connectivity and I/O for sensor aggregation With 19 general-purpose I/Os and a serial-communication block that supports I²C, SPI, UART/USART, LINbus, IrDA, Microwire, SmartCard, and SSP, this MCU can aggregate data from multiple sensors and talk to a host controller or cloud module over a single bus. The internal oscillator keeps the BOM simple — no external crystal needed for most applications. The 10-bit ADC with 16 channels handles analog sensor inputs directly. ## Temperature grade and environment Rated for -40°C to 85°C ambient, the CY8C4745LQI-S411 is suited for industrial control panels, outdoor telecom equipment, appliance front-ends, and automotive cabin modules. The 24-QFN package with exposed pad helps pull heat into the PCB ground plane, keeping the die cool in enclosed or warm environments. ## Lifecycle and sourcing Infineon lists this part as Active with ROHS3 compliance. No end-of-life notice or last-time-buy window is in effect, so it is safe to qualify into new production runs. For current pricing and availability, submit an RFQ — we source through independent distribution and confirm pricing and lead time at quote.","metaTitle":"CY8C4745LQI-S411 PSoC 4 MCU, 48MHz ARM Cortex-M0+","metaDescription":"CY8C4745LQI-S411 PSoC 4 MCU from Infineon: 48MHz ARM Cortex-M0+, 32KB Flash, 4Kx8 RAM, CapSense, LCD drive, 1.71V–5.5V supply, -40°C to 85°C.
