It carries 44 I/O lines, a 12-channel 14-bit ADC, and a 4-channel 9-bit DAC — mixed-signal resources that let it handle sensor conditioning and analog control loops without external converters. Communication interfaces include I²C, SPI, and UART/USART. The supply range spans 3 V to 5.25 V, and the operating temperature covers -40°C to 85°C, so it fits industrial enclosures, outdoor telecom pedestals, and factory-floor control modules. ## Mixed-signal integration — what it saves on the board The 12-channel 14-bit successive-approximation ADC and the four 9-bit DACs are the headline differentiators for an 8-bit MCU. In a temperature-monitoring or pressure-transducer application, the ADC can sample multiple analog inputs directly; the DACs can drive a setpoint or trim voltage without an external D/A converter. The internal oscillator eliminates the external crystal for many designs, though you still have the option to feed an external clock if the application needs tighter timing than the internal RC can hold. ## Lifecycle and sourcing posture This part carries an Active lifecycle status and is ROHS3 compliant. For dual-sourcing flexibility within the same PSOC1 family, the CY8C29566-24AXIT offers the same core, memory, and mixed-signal peripherals in a TQFP package — a drop-in functional match if the board layout accommodates the different footprint.","metaTitle":"Infineon CY8C29666-24PVXIT PSOC1 MCU, 8-Bit 24MHz","metaDescription":"Infineon CY8C29666-24PVXIT 8-bit PSOC1 MCU: M8C core at 24MHz, 32KB Flash, 2Kx8 RAM, 12x14b ADC, 4x9b DAC, I²C/SPI/UART, -40°C to 85°C.
