The 32 KB on-chip flash and 4K x 8 SRAM leave headroom for control loops, sensor fusion, or a small RTOS. The 1K x 8 EEPROM stores calibration constants without wearing the flash. The 62 I/O lines and integrated CapSense, DMA, and PWM peripherals reduce external glue logic – a single chip can handle touch sensing, motor commutation, and host communication. ## Industrial temperature grade and wide supply – fit for factory-floor designs The 1.71V to 5.5V supply range lets the MCU sit on a 3.3V or 5V rail without an external regulator – useful for retrofitting legacy 5V boards or battery-powered 1.8V systems. ## Active lifecycle and ROHS3 compliance – planning for production runs Supplied in a tray, 100-TQFP (14x14 mm) – the 0.50 mm pitch demands a 4-layer PCB for clean fan-out. The package footprint is shared across the PSOC® 3 family, simplifying board reuse.","metaTitle":"CY8C3445AXI-104 PSOC® 3 MCU – 8051 50MHz 32KB Flash 100-TQFP","metaDescription":"CY8C3445AXI-104 – Infineon PSOC® 3, 8-bit 8051 core at 50MHz, 32KB Flash, 4Kx8 RAM, 1Kx8 EEPROM, 62 I/O, industrial temp -40°C to 85°C, 100-TQFP.","metaKeywords":null},"attributes":{"series":"PSOC® 3 CY8C34xx","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Speed":"50MHz","Series":"PSOC® 3 CY8C34xx","Package":"Tray","RAM Size":"4K x 8","Core Size":"8-Bit","EEPROM Size":"1K x 8","Peripherals":"CapSense, DMA, POR, PWM, WDT","Connectivity":"EBI/EMI, I²C, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"62","Core Processor":"8051","Package / Case":"100-LQFP","Data Converters":"A/D 16x12b; D/A 2x8b","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":"100-TQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.81","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$12.81000","currency":"USD"},{"qty":10,"price":"$11.77400","currency":"USD"},{"qty":25,"price":"$11.28560","currency":"USD"},{"qty":90,"price":"$9.94367","currency":"USD"},{"qty":270,"price":"$9.45563","currency":"USD"},{"qty":450,"price":"$8.84558","currency":"USD"},{"qty":990,"price":"$8.11354","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/033a7647e9725ad6556608a72e8ec755.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY8C3445AXI-104","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY8C3445AXI-104 when reusing this data.
