The 28-channel 8-bit ADC is the headline analog resource: it samples up to 28 single-ended inputs at 8-bit resolution, suitable for threshold detection, level monitoring, or low-resolution sensor readout without an external converter. The serial interface set — I²C, SPI, and UART/USART — covers the common bus protocols for connecting to sensors, displays, or a host controller. ## Supply, temperature, and package — single-rail industrial MCU The 16 general-purpose I/O share the package with the serial interface pins and the analog input channels — the pin allocation is fixed, so the board layout should reserve the ADC inputs for the sensor front-end and the serial pins for the bus interface. ## On-chip peripherals — POR, PWM, WDT, internal oscillator The POR (Power-On Reset) eliminates the external reset supervisor IC; the PWM output drives a buzzer, LED, or small motor without a dedicated timer peripheral; the WDT (Watchdog Timer) resets the MCU if the firmware hangs. The internal oscillator runs the core at 24 MHz without an external crystal — the accuracy is adequate for UART baud-rate generation at this speed.","metaTitle":"Infineon CY8C21334-24PVXIT PSoC1 MCU, 8KB Flash, 24MHz","metaDescription":"Infineon CY8C21334-24PVXIT PSoC1 8-bit MCU, 24MHz M8C core, 8KB Flash, 512B SRAM, 28-ch 8-bit ADC, 16 I/O, I²C/SPI/UART, -40 to 85°C, 20-SSOP.
