That clock rate is the throughput ceiling for the application, but the real value is the programmable analog and digital fabric that offloads the CPU — CapSense touch sensing, DMA data movement, LCD drive, PWM generation, and a watchdog timer are all on-chip peripherals that run without core intervention. With 256 KB of program flash and 64 KB of SRAM, this part has room for a moderate application stack — think a sensor hub with a graphical LCD, a motor control loop with fieldbus communication, or a human-machine interface with capacitive touch buttons. The 2 KB EEPROM is separate from the flash, so calibration constants or configuration parameters survive a firmware update without a dedicated EEPROM chip on the board. ## Industrial temperature grade and wide supply — design margin for harsh environments The supply range from 1.71V to 5.5V means this MCU can run directly from a 3.6V Li-ion cell, a 5V regulated rail, or a 1.8V low-power supply without an external regulator — a real BOM simplification when the system has multiple voltage domains. The 62 general-purpose I/O pins in a 100-TQFP package (14x14 mm body) give enough headroom for a parallel LCD data bus, a few SPI/I²C sensor interfaces, and a handful of discrete inputs and outputs. The 0.50 mm pitch on the TQFP is manageable on a 4-layer board; a 2-layer board can break out the outer rows but will struggle with the inner power/ground pads. ROHS3 compliance is confirmed. For volume production, check with your sourcing contact about reel availability — the tray is standard for engineering samples and low-to-mid volume builds.","metaTitle":"CY8C5468AXI-LP106 Infineon PSOC 5 MCU 67MHz 256KB Flash","metaDescription":"CY8C5468AXI-LP106 Infineon PSOC 5 MCU: ARM Cortex-M3 32-bit, 67MHz, 256KB Flash, 64KB SRAM, industrial temp -40°C to 85°C, 100-TQFP.","metaKeywords":null},"attributes":{"series":"PSOC® 5 CY8C54LP","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Crystals & Oscillators"],"specifications":{"Speed":"67MHz","Series":"PSOC® 5 CY8C54LP","Package":"Tray","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"2K x 8","Peripherals":"CapSense, DMA, LCD, POR, PWM, WDT","Connectivity":"I²C, LINbus, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"62","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Data Converters":"A/D 1x12b; D/A 2x8b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"256KB (256K 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":"$13.6","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$13.60000","currency":"USD"},{"qty":10,"price":"$12.49500","currency":"USD"},{"qty":25,"price":"$11.97720","currency":"USD"},{"qty":90,"price":"$10.55278","currency":"USD"},{"qty":270,"price":"$10.03485","currency":"USD"},{"qty":450,"price":"$9.38744","currency":"USD"},{"qty":990,"price":"$8.61056","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/33b05c8048780fecb2664ab8e7029ddb.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY8C5468AXI-LP106 a direct replacement for CY8C5468AXI-xxx?","answer":"The 'LP106' suffix indicates a specific speed grade (67 MHz) and feature set. Within the PSOC 5 CY8C54LP series, other suffix variants may differ in flash size, SRAM, or peripheral mix. Always compare the full parametric table — pin-compatibility is not guaranteed across the whole family without checking the datasheet pinout."},{"question":"Does CY8C5468AXI-LP106 have an internal oscillator or require an external clock?","answer":"The oscillator type is listed as Internal. The PSOC 5 devices include an internal oscillator that can serve as the system clock, reducing external component count. For precision timing (e.g., USB or CAN), an external crystal may still be needed — the internal oscillator accuracy is sufficient for most general-purpose applications."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY8C5468AXI-LP106","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY8C5468AXI-LP106 when reusing this data.
