The 64 KB Flash ceiling suits firmware images that include a bootloader plus a moderate application layer — a typical CapSense-based UI or sensor-fusion algorithm fits without external memory. The 38 I/O lines are multiplexed with the CapSense, LCD segment drive, and PWM outputs, so the actual usable I/O count depends on which peripherals are enabled — a full LCD segment drive can consume 16–24 pins, leaving 14–22 for general-purpose use. The data converter block provides 16 multiplexed inputs to a single 12-bit SAR ADC, plus a separate 8-bit DAC. The ADC sample rate is not listed in the summary, but the 12-bit resolution and 16-channel mux are typical for reading multiple analog sensors (potentiometers, thermistors, strain gauges) on a single conversion cycle.","metaTitle":"Infineon CY8C3246LTI-149 PSOC 3 MCU, 50MHz, 64KB Flash","metaDescription":"Active-production Infineon CY8C3246LTI-149 8-bit 8051 MCU, 50MHz, 64KB Flash, 8Kx8 RAM, 2Kx8 EEPROM, 38 I/O, 68-QFN.
