The 24 MHz core is half the speed of the sibling CY8C4245LQI-483 (48 MHz), but the trade-off is lower active current and a lower BOM cost for applications that don't need the throughput — think a thermostat panel or a simple pump controller, not a high-speed data logger. ## Package and footprint – 48-TQFP The 48-pin TQFP (7×7 mm, 0.5 mm pitch) is a common footprint shared across the PSoC 4 family, so a board laid out for the CY8C4125 can often accept a higher-density sibling with the same pin count and supply voltage.","metaTitle":"CY8C4125AZI-473 PSoC 4 MCU, ARM Cortex-M0, 24 MHz","metaDescription":"Infineon CY8C4125AZI-473 32-bit ARM Cortex-M0 MCU, 24 MHz, 32 KB Flash, 8x12b SAR ADC, 2xIDAC, 36 I/O, -40 to 85°C, 48-TQFP.
