The 2.4 V minimum supply voltage also supports single-cell Li-ion or 3.3 V rails with dropout margin, which is useful in battery-backed or energy-harvesting designs. ## 28-channel ADC and serial interfaces in a small footprint With 28 analog inputs multiplexed into an 8-bit ADC, this MCU can read a bank of thermistors, potentiometers, or current-sense resistors without an external analog mux. On-chip peripherals include POR, PWM, and WDT, reducing the need for external supervisory ICs.","metaTitle":"CY8C21334-12PVXE PSoC 1 MCU, 8-bit M8C, 12 MHz, 8KB Flash","metaDescription":"Cypress CY8C21334-12PVXE 8-bit PSoC 1 MCU with M8C core at 12 MHz, 8KB Flash, 28x8b ADC, I²C/SPI/UART, -40°C to 125°C.
