The 3 V nominal supply rail keeps power dissipation low — useful in loop-powered or battery-backed designs. ## On-chip ADC and configurable blocks The PSoC 1 architecture also includes programmable digital blocks that can implement PWM, timers, counters, UART, SPI, or I²C — the connectivity list covers I²C, IrDA, SPI, and UART/USART, so most serial sensor or actuator links can be handled without extra glue logic.","metaTitle":"CY8C21345-24SXI PSoC 1 MCU, 8-bit M8C 24 MHz, 8 KB Flash","metaDescription":"Infineon CY8C21345-24SXI 8-bit PSoC 1 MCU, M8C core at 24 MHz, 8 KB Flash, 3x10b ADC, 24 I/O, -40°C to 85°C, 28-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"series":"PSOC®1 CY8C21xxx","has_mpn":"CY8C21345","cpu_core":"M8C","frame_size":"8-Bit","fuse_speed":"24 MHz","connectivity":"I²C, IrDA, SPI, UART/USART","package_type":"Tube","Number Of I/O":"24","mounting_type":"Surface Mount","product_status":"Active","Data Converters":"A/D 3x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","peripheral_types":"LVD, POR, PWM, WDT","supply_voltage_v":"3.0","Program Memory Type":"FLASH","Operating Temperature High":"-40°C to 85°C (TA)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.53","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5f46be52b7297c2a5217ed6cf433769f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY8C21345-24SXI/alternatives.json"},"ai":{"faq":[{"question":"Where can I find the datasheet for CY8C21345-24SXI?","answer":"The datasheet is available from Infineon's website under the PSoC 1 CY8C21xxx series documentation.
