The supply voltage is specified at 3 V, and the part is not rated for 5 V operation — a common question when replacing older 5 V logic. If your design runs a 5 V bus, you will need level translation or a different PSoC 1 variant. The 24 I/O lines are 3 V-tolerant and can interface with 3.3 V peripherals directly, but driving a 5 V input without translation risks exceeding the absolute maximum ratings. ## Package and footprint — 28-pin SSOP The CY8C21512-24PVXA comes in a 28-lead SSOP (shrink small-outline package) with a 0.65 mm pitch. It is a surface-mount package suited for reflow assembly. The 'XA' suffix indicates a lead-free / RoHS-compliant finish, so no special baking or handling beyond standard MSL precautions is needed for lead-free solder profiles. ## Lifecycle status — active, no LTB risk This makes it safe to qualify into new designs and to continue sourcing for existing BOMs without obsolescence-driven redesign.","metaTitle":"CY8C21512-24PVXA PSoC 1 MCU, 8-bit M8C, 24 MHz, 8 KB Flash","metaDescription":"Infineon CY8C21512-24PVXA 8-bit PSoC 1 MCU with M8C core at 24 MHz, 8 KB Flash, 24 I/O, I²C/SPI/UART, industrial temp -40 to 85°C.","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":"CY8C21512","cpu_core":"M8C","frame_size":"8-Bit","fuse_speed":"24 MHz","connectivity":"I²C, SPI, UART/USART","package_type":"Bulk","Number Of I/O":"24","mounting_type":"Surface Mount","product_status":"Active","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":"$3.61","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/724bc22b28dff8004819551dded03580.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY8C21512-24PVXA/alternatives.json"},"ai":{"faq":[{"question":"Can CY8C21512-24PVXA be replaced by CY8C21512-24PVXI?","answer":"The CY8C21512-24PVXI is the same die in the same 28-SSOP package but with a different temperature grade — the 'I' suffix typically denotes -40°C to 85°C as well, while the 'XA' suffix on this part indicates RoHS compliance.
