The 16 KB flash and 2 KB RAM budget fits moderate sensor-fusion and human-interface applications where the CapSense peripheral handles touch sensing without a separate controller. ## 16-channel 12-bit ADC and serial connectivity The integrated 16-channel, 12-bit ADC samples analog sensors directly — thermistors, potentiometers, current-shunt outputs — without an external converter. A single 8-bit DAC provides analog output for set-point or trim signals. ## 48-QFN footprint and industrial temperature grade Housed in a 48-VFQFN exposed-pad package measuring 7x7 mm, the CY8C3244LTI-123T suits space-constrained PCBs. The ROHS3 compliance (no exemptions) avoids future substance-restriction supply-chain issues.","metaTitle":"CY8C3244LTI-123T PSOC 3 MCU, 50 MHz 8051, 16 KB Flash","metaDescription":"Active-production Infineon CY8C3244LTI-123T PSOC 3 8-bit MCU: 50 MHz 8051 core, 16 KB flash, 2 KB RAM, 512 B EEPROM, CapSense, 48-QFN.
