The 62 I/O lines in the 100-pin LQFP give enough headroom for parallel buses (EBI/EMI) alongside the usual I²C, SPI, UART, and USB interfaces. At 50 MHz the single-cycle 8051 pipeline executes most instructions in one or two clock ticks, so the effective throughput is well above what a legacy 12-clock-per-cycle 8051 delivers at the same frequency. For timing-critical loops — like servicing a USB endpoint or running a PWM update at audio rates — the 50 MHz clock keeps the interrupt latency under a microsecond.","metaTitle":"CY8C3246AXI-138 PSoC 3 MCU, 8-Bit 8051, 50MHz, 64KB Flash","metaDescription":"Infineon CY8C3246AXI-138 PSoC 3 MCU: 8-bit 8051 core at 50MHz, 64KB Flash, 8KB SRAM, CapSense, LCD drive, USB, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"PSOC® 3 CY8C32xx","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Speed":"50MHz","Series":"PSOC® 3 CY8C32xx","Package":"Tray","RAM Size":"8K x 8","Core Size":"8-Bit","EEPROM Size":"2K 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":"62","Core Processor":"8051","Package / Case":"100-LQFP","Data Converters":"A/D 16x12b; D/A 1x8b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"64KB (64K 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":"$14.0","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$14.00000","currency":"USD"},{"qty":10,"price":"$12.86500","currency":"USD"},{"qty":25,"price":"$12.33200","currency":"USD"},{"qty":90,"price":"$10.86556","currency":"USD"},{"qty":270,"price":"$10.33230","currency":"USD"},{"qty":450,"price":"$9.66569","currency":"USD"},{"qty":990,"price":"$8.86578","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ca1be62407dfa0bc41d1655ecfdd98f1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can CY8C3246AXI-138 be programmed with PSoC Creator?","answer":"Yes, PSoC Creator is the official IDE for the PSoC 3 family and supports the CY8C3246AXI-138 with full graphical configuration for the digital and analog blocks."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY8C3246AXI-138","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY8C3246AXI-138 when reusing this data.
