For a panel with a few touch buttons and a simple segment display, you skip the external touch controller and display driver IC — that saves board area and a couple of dollars in BOM cost. On a battery-powered design, the lower end lets it keep running as the cells drain. The 28-SSOP package is a surface-mount, 0.209\"-wide body with a 5.30 mm width — a standard SOIC-like footprint that reflows cleanly and is inspectable without X-ray.","metaTitle":"CY8C4045PVI-DS402 PSOC 4 MCU, 48 MHz Cortex-M0, 32 KB Flash","metaDescription":"Infineon CY8C4045PVI-DS402 32-bit ARM Cortex-M0 MCU, 48 MHz, 32 KB Flash, 4K x 8 RAM, 21 I/O, 28-SSOP, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"PSOC® 4 CY8C42xx-DS","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Speed":"48MHz","Series":"PSOC® 4 CY8C42xx-DS","Package":"Tube","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":"21","Core Processor":"ARM® Cortex®-M0","Package / Case":"28-SSOP (0.209\\\", 5.30mm Width)","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":"28-SSOP","Voltage - Supply (Vcc/Vdd)":"1.7V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.84","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.84000","currency":"USD"},{"qty":10,"price":"$2.54800","currency":"USD"},{"qty":25,"price":"$2.40880","currency":"USD"},{"qty":100,"price":"$2.08770","currency":"USD"},{"qty":250,"price":"$1.98060","currency":"USD"},{"qty":500,"price":"$1.77720","currency":"USD"},{"qty":1000,"price":"$1.49884","currency":"USD"},{"qty":2500,"price":"$1.42390","currency":"USD"},{"qty":5000,"price":"$1.37037","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/9baa6ab204c74c1ee4eb4872315eefda.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does CY8C4045PVI-DS402 support capacitive sensing without external components?","answer":"Yes, the part integrates CapSense blocks on-chip, so you can implement touch buttons and sliders without an external capacitive-sensing controller.
