The standout features are the integrated CapSense touch-sensing engine, a full-speed USB 2.0 interface, and a segment LCD drive controller, all in a 48-pin SSOP package with 25 I/O. The supply range spans 1.71 V to 5.5 V, so it can run directly from a Li-ion cell or a 3.3 V / 5 V rail without an extra regulator. ## Peripheral set and memory — what fits where The 4 KB RAM is tight for heavy data buffering — plan for external SRAM over the EBI/EMI interface if you need more. The 12-bit ADC with 16 channels and the single 8-bit DAC handle sensor acquisition and analog output without an external converter. ## Package and power — layout notes The 25 I/O are 5 V tolerant on most pins, simplifying level translation to legacy peripherals. The internal POR and WDT reduce external supervisor IC count. ## Lifecycle and sourcing It is ROHS3 compliant.","metaTitle":"CY8C3245PVI-150 PSOC 3 MCU, 8-Bit 8051, 50 MHz, 32 KB Flash","metaDescription":"Infineon CY8C3245PVI-150 PSOC 3 8-bit MCU: 8051 core at 50 MHz, 32 KB Flash, 4 KB RAM, 1 KB EEPROM, CapSense, USB, -40°C to 85°C, 48-SSOP.","metaKeywords":null},"attributes":{"series":"PSOC® 3 CY8C32xx","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Speed":"50MHz","Series":"PSOC® 3 CY8C32xx","Package":"Tube","RAM Size":"4K x 8","Core Size":"8-Bit","EEPROM Size":"1K x 8","Peripherals":"CapSense, DMA, LCD, POR, PWM, WDT","Connectivity":"EBI/EMI, I²C, LINbus, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"25","Core Processor":"8051","Package / Case":"48-BSSOP (0.295\\\", 7.50mm Width)","Data Converters":"A/D 16x12b; D/A 1x8b","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-SSOP","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.07","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$10.07000","currency":"USD"},{"qty":10,"price":"$9.09900","currency":"USD"},{"qty":25,"price":"$8.67520","currency":"USD"},{"qty":100,"price":"$7.53280","currency":"USD"},{"qty":250,"price":"$7.19424","currency":"USD"},{"qty":500,"price":"$6.55944","currency":"USD"},{"qty":1000,"price":"$5.71306","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ca1be62407dfa0bc41d1655ecfdd98f1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does CY8C3245PVI-150 have a cross-reference or equivalent?","answer":"Within the PSOC 3 family, the CY8C3245PVI-150 is a specific density and package variant; for a different core architecture, the PSOC 4 series (e.g., CY8C4245LQI-483) uses an ARM Cortex-M0 but is not pin-compatible.
