It packs 32 KB of Flash program memory and 4K x 8 SRAM. ## 21 I/O in a 28-SSOP — board-area budget The 28-SSOP package (5.30 mm body width) gives 21 general-purpose I/O lines. That footprint fits a two-layer PCB for a capacitive touch panel with four sensor inputs, a UART to a host controller, and an SPI interface to a display driver — with a few pins left for status LEDs and a pushbutton. The 0.209-inch (5.30 mm) width is the same as a standard SOIC-28, so existing land patterns often carry over with minor tweaks. ## Peripherals that cut external BOM On-chip CapSense eliminates the need for a separate touch controller in appliance and industrial HMI designs. ## Connectivity options for industrial buses The CY8C4245PVI-DS402T supports I²C, SPI, UART/USART, IrDA, LINbus, Microwire, SmartCard, and SSP. That covers most sensor and actuator links on a factory floor — LIN for automotive sub-systems, I²C for local sensor arrays, and UART for Modbus RTU gateways. The internal oscillator trims to 48 MHz, so no external crystal is needed for many applications, though an external clock can be fed in for tighter timing. ## Lifecycle and compliance — no LTB risk The CY8C4245PVI-DS402T is listed as Active in production with ROHS3 compliance. For new designs or production replenishment, this part is a safe call — no forced redesign horizon.","metaTitle":"CY8C4245PVI-DS402T PSOC 4 MCU, 48MHz Cortex-M0, 32KB Flash","metaDescription":"Infineon CY8C4245PVI-DS402T 32-bit ARM Cortex-M0 MCU, 48MHz, 32KB Flash, 4Kx8 RAM, 28-SSOP, -40 to 85°C.
