The 4 KB SRAM is tight for heavy buffering, but the part is designed for control-oriented applications where the data stays in registers or Flash lookup tables. If you need Bluetooth or more memory, the CY8C4247LQI-BL473 adds BLE and a larger Flash bank, but for a wired HMI or sensor node this is the right density tier. ## Sourcing this part for your BOM line The CY8C4245AXI-483 is sourced through independent distribution and quoted to order against an RFQ. Availability and current pricing are confirmed at quote time — no stock or price figures are published here because the market moves. For a BOM freeze, the active lifecycle means no imminent LTB, but dual-sourcing with the CY8C4245LQI-483 (same core, same peripherals, 34 I/O in a QFN) gives supply resilience if the TQFP variant tightens.","metaTitle":"Infineon CY8C4245AXI-483 PSoC 4 MCU, 48MHz ARM Cortex-M0","metaDescription":"CY8C4245AXI-483 PSoC® 4 MCU: 48MHz ARM Cortex-M0, 32KB Flash, 4KB SRAM, CapSense, 44-TQFP.
