The 68-VFQFN package with exposed pad (8x8 mm) keeps the footprint compact while the pad aids thermal dissipation in enclosed or convection-limited enclosures. ## On-chip analog and touch — CapSense, 12-bit ADC, 8-bit DAC The CY8C3244LTI-130 integrates a 16-channel 12-bit ADC and a single 8-bit DAC, plus CapSense capacitive-touch sensing hardware. For a panel with touch buttons, a slider, and an analog sensor input, this MCU handles the entire front-end without external ADC or touch-controller ICs. The DMA engine moves data between peripherals and memory without CPU intervention, freeing the 8051 core for higher-level control or communication stack processing. The PSOC 3 family has been in the field for years, and the toolchain (PSoC Creator) is mature and stable — no migration pressure from the vendor. ## Peripheral connectivity and I/O count With 38 general-purpose I/O pins and interfaces spanning EBI/EMI, I²C, LINbus, SPI, and UART/USART, this MCU can bridge to external memory, sensor networks, and serial displays.","metaTitle":"CY8C3244LTI-130 PSOC 3 8-bit MCU, 50 MHz, 16 KB Flash","metaDescription":"Infineon CY8C3244LTI-130 PSOC 3 8-bit 8051 MCU with 50 MHz core, 16 KB Flash, 2K x 8 RAM, 512 x 8 EEPROM, 16x12b ADC, 1x8b DAC, CapSense, -40 to 85°C.","metaKeywords":null},"attributes":{"series":"PSOC® 3 CY8C32xx","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Speed":"50MHz","Series":"PSOC® 3 CY8C32xx","Package":"Tray","RAM Size":"2K x 8","Core Size":"8-Bit","EEPROM Size":"512 x 8","Peripherals":"CapSense, DMA, POR, PWM, WDT","Connectivity":"EBI/EMI, I²C, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"38","Core Processor":"8051","Package / Case":"68-VFQFN Exposed Pad","Data Converters":"A/D 16x12b; D/A 1x8b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"16KB (16K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"68-QFN (8x8)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.21","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$9.21000","currency":"USD"},{"qty":10,"price":"$8.31700","currency":"USD"},{"qty":25,"price":"$7.93000","currency":"USD"},{"qty":80,"price":"$6.88563","currency":"USD"},{"qty":260,"price":"$6.57612","currency":"USD"},{"qty":520,"price":"$5.99587","currency":"USD"},{"qty":1040,"price":"$5.22220","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ca1be62407dfa0bc41d1655ecfdd98f1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can CY8C3244LTI-130 be used in 5V systems?","answer":"Yes.

However, the CY8C4245LQI-483 operates at a maximum of 3.6 V (not 5 V) and is not a direct pin-compatible drop-in — it requires a board-level redesign and a voltage regulator if migrating from a 5 V system.
