The CYUSB2024-BZXI runs an ARM9 core — a cached 5-stage pipeline that pushes USB throughput without a heavy interrupt load on the application side. The 512K x 8 RAM (512 KB) is the full working memory; there is no separate flash for code execution, so the firmware image must fit entirely in that 512 KB space and the bootloader must load it over USB or from an external SPI/MMC source.
Supply rails and temperature — the operating envelope
The 121-TFBGA (10x10 mm) package routes the core and I/O rails through separate ball groups; a standard 1.2 V LDO with ±2% tolerance stays inside the window across load transients. Industrial temperature grade: -40°C to 85°C. The ARM9 core's dynamic power scales with clock frequency; at the high end of the temperature range, the 121-ball BGA's thermal resistance (not given here) dictates the maximum sustained USB throughput.
