The supply voltage range spans 1.71 V to 5.5 V, so it can run from a single Li-ion cell or a regulated 3.3 V / 5.0 V rail without an external LDO. On-chip peripherals include a 16-channel 10-bit ADC, brown-out and low-voltage detect, POR, PWM timers, and a watchdog timer. ## WLCSP rework and handling notes The 25-WLCSP package has a 0.4 mm ball pitch typical for this class. The small body means the die is close to the board surface, so the reflow profile needs a controlled ramp rate to avoid thermal shock. The 21 GPIOs are all that fit in the 25-ball array. For designs needing more I/O, the QFN-packaged siblings in the same PSoC 4 family offer 34 or 36 I/O in a larger footprint. ## Lifecycle and compliance It is ROHS3 compliant.","metaTitle":"CY8C4745FNI-S412T PSoC 4 MCU, ARM Cortex-M0+, 48 MHz","metaDescription":"Infineon CY8C4745FNI-S412T PSoC 4 MCU: 32-bit ARM Cortex-M0+ at 48 MHz, 32 KB Flash, 4 KB SRAM, CapSense, LCD drive, -40 to 85°C, 25-WLCSP.","metaKeywords":null},"attributes":{"series":"PSOC® 4 CY8C4700S","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Speed":"48MHz","Series":"PSOC® 4 CY8C4700S","Package":"Tape & Reel (TR); Cut Tape (CT)","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":"25-XFBGA, WLCSP","Data Converters":"A/D 16x10b","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":"25-WLCSP (2.02x1.93)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.48","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.48000","currency":"USD"},{"qty":10,"price":"$5.81700","currency":"USD"},{"qty":25,"price":"$5.49960","currency":"USD"},{"qty":100,"price":"$4.76620","currency":"USD"},{"qty":250,"price":"$4.52176","currency":"USD"},{"qty":500,"price":"$4.05738","currency":"USD"},{"qty":1000,"price":"$3.42188","currency":"USD"},{"qty":2000,"price":"$3.25079","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/fd91ff9b3e4468a8e245bd6719b8d894.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY8C4745FNI-S412T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY8C4745FNI-S412T when reusing this data.
