The data converters comprise a 16-channel 10-bit slope ADC, a 16-channel 12-bit SAR ADC, and two IDAC outputs, covering basic analog front-end needs for sensor conditioning or capacitive touch. Connectivity spans I2C, SPI, UART/USART, IrDA, LINbus, Microwire, SmartCard, and SSP — enough serial interface variety to talk to common sensors, displays, and fieldbus transceivers without a protocol translator. ## 48-TQFP package and industrial temperature grade Housed in a 48-TQFP (7x7 mm) package with 36 GPIOs brought out, the part is suited for reflow assembly and manual rework.","metaTitle":"CY8C4126AZI-S433T Infineon PSoC 4 MCU, 24MHz, 64KB Flash","metaDescription":"CY8C4126AZI-S433T ARM Cortex-M0+ MCU, 24MHz, 64KB Flash, 8Kx8 RAM, 36 I/O, -40°C to 85°C, 48-TQFP.
