The M8C core runs at 12 MHz. The 8 KB Flash is sized for moderate firmware — think a fan controller, a battery charger state machine, or a small HMI overlay. ## I²C, SPI, UART — three serial buses on one die That means a single MCU can talk to a temperature sensor over I²C, drive a small SPI display, and send debug or telemetry data out a UART — no external bridge chip needed. The 24 I/O lines leave room for local buttons, LEDs, and a few discrete sensor inputs alongside the serial traffic.","metaTitle":"CY8C21512-12PVXE PSoC1 8-bit MCU, 12 MHz, 8KB Flash","metaDescription":"Infineon/Cypress CY8C21512-12PVXE PSoC1 8-bit M8C MCU, 12 MHz, 8KB Flash, 24 I/O, I²C/SPI/UART, -40°C to 125°C.
