It carries 16 KB of on-chip Flash program memory and operates from a 1.71 V supply rail, suiting it for battery-powered and portable instrumentation where a single low-voltage rail is available. What distinguishes this part from a plain digital MCU is the integrated mixed-signal front-end: an 8-channel 12-bit SAR ADC and two current-output IDACs, plus a CapSense touch-sensing block and an LCD drive controller. These peripherals let a single chip handle capacitive touch buttons, sliders, or proximity sensing alongside basic analog measurement without external converter ICs. The 48 MHz Cortex-M0 core places the CY8C4244AZI-443 in the low-power, cost-optimised tier of the PSoC 4 family. It is not a performance part — the sibling PSoC 6 CY8C6137BZI-F54 runs a Cortex-M4 at 150 MHz with 1 MB-class Flash — but for a touch-interface controller, a sensor hub, or a simple human-machine interface (HMI), the M0 at 48 MHz draws less current and keeps the BOM cost down. ## CapSense and LCD drive — what the peripheral set buys you The CapSense block eliminates the need for a dedicated touch controller IC in panel designs — the MCU handles capacitive touch directly, reducing component count and firmware complexity. The LCD drive peripheral can run a segment LCD without an external driver chip, useful for low-cost displays in appliance or industrial HMI panels. Both peripherals are supported by Infineon's PSoC Creator IDE, which provides graphical configuration and tuning tools.","metaTitle":"CY8C4244AZI-443 PSoC 4 MCU, 48 MHz ARM Cortex-M0","metaDescription":"Infineon CY8C4244AZI-443 PSoC 4 MCU: ARM Cortex-M0 at 48 MHz, 16 KB Flash, 8x12b SAR ADC, 2xIDAC, CapSense, 36 I/O, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"series":"PSOC® 4 CY8C42xx","has_mpn":"CY8C4244","cpu_core":"ARM® Cortex®-M0","frame_size":"32-Bit Single-Core","fuse_speed":"48 MHz","connectivity":"I2C, IrDA, LINbus, Microwire, SmartCard, SPI, SSP, UART/USART","package_type":"Tray","Number Of I/O":"36","mounting_type":"Surface Mount","product_status":"Active","Data Converters":"A/D 8x12b SAR; D/A 2xIDAC","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","peripheral_types":"Brown-out Detect/Reset, CapSense, LCD, LVD, POR, PWM, WDT","supply_voltage_v":"1.71","Program Memory Type":"FLASH","Operating Temperature High":"-40°C to 85°C (TA)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.48","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e5f484480ae4d569e929a84cc6cbf381.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY8C4244AZI-443/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY8C4244AZI-443","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY8C4244AZI-443 when reusing this data.
