M8C core at 24 MHz — sensor-loop timing budget
The CY8C21534-24PVXI runs an 8-bit M8C core at 24 MHz, with 8 KB of on-chip Flash and 512 x 8 bytes of RAM. The 24 MHz clock drives the internal POR, PWM, and WDT peripherals — enough headroom for a 10 kHz sensor read loop with the ADC sampling at 8-bit resolution. 28 analog inputs are multiplexed into a single 8-bit ADC, meaning every I/O pin on the 28-SSOP package can serve as an analog channel. This density suits multi-sensor arrays in panel instruments or environmental monitors where PCB space is tight.
Supply voltage spans 2.4 V to 5.25 V, covering both 3.3 V and 5 V logic rails without an external regulator. The POR and WDT peripherals add brown-out and watchdog coverage without external supervisor ICs.
The tube delivery suits low-to-medium volume builds; for high-volume tape-and-reel, confirm availability with your Infineon contact.
