The 4 KB flash and 256 x 8 RAM set the firmware and data buffer ceiling — enough for a single control loop with a small state machine, but tight for a protocol stack with multiple buffers. Twelve I/O in a 16-SOIC package (0.154\" body, 3.90 mm width) means every pin counts. The 8-channel 8-bit ADC handles slow analog inputs like temperature or potentiometer feedback; the I²C, SPI, and UART/USART blocks cover common sensor and actuator buses without external shift registers.","metaTitle":"Infineon CY8C21223-24SXI PSoC1 MCU, 8-bit M8C, 24 MHz","metaDescription":"CY8C21223-24SXI 8-bit PSoC1 MCU with M8C core at 24 MHz, 4 KB Flash, 256 B RAM, 12 I/O, I²C/SPI/UART, -40°C to 85°C.
