It packs a 10-channel 14-bit ADC and a 2-channel 9-bit DAC, plus I²C, SPI, and UART/USART serial interfaces — enough analog front-end and digital connectivity to handle sensor conditioning, simple control loops, or human-interface tasks without external converters. The 24 I/O lines, POR/PWM/WDT peripherals, and internal oscillator mean you can run a small mixed-signal board with few external parts. Housed in a 28-pin SSOP (0.209-inch body width, 5.30 mm wide), surface-mount. ## Where the CY8C24423A-24PVXI fits vs a larger sibling The CY8C29466-24PVXI runs the same M8C core at the same 24 MHz but packs 32 KB Flash and 2 KB RAM — eight times the program memory — plus a 12-channel 14-bit ADC and a 4-channel 9-bit DAC. It also comes in a 28-SSOP package, so the footprint is identical. If your code fits in 4 KB and you do not need the extra analog channels, the CY8C24423A-24PVXI is the cost-optimised choice; if you are bumping up against Flash or need more ADC inputs, the CY8C29466-24PVXI is a drop-in upgrade without a board spin.","metaTitle":"CY8C24423A-24PVXI Infineon PSoC1 MCU, 8-Bit, 24MHz, 28-SSOP","metaDescription":"Infineon CY8C24423A-24PVXI 8-bit PSoC1 MCU, 24MHz, 4KB Flash, 28-SSOP, -40°C to 85°C.
