At 24 MHz the Cortex-M0 delivers enough cycles for sensor polling, serial protocol handling, and simple control loops. If your application needs faster data processing or higher PWM resolution, the sibling CY8C4245LQI-483 runs at 48 MHz — double the clock — with the same peripheral set and package options. ## Memory sizing for firmware and data 16 KB Flash and 4 KB SRAM suit firmware for HMI front-ends, capacitive touch interfaces, or basic sensor nodes. The 4 KB SRAM is the working memory budget — enough for a few UART buffers and a modest state machine, but tight for large lookup tables or frame buffers. ## Peripherals that reduce external BOM CapSense eliminates dedicated touch-controller ICs for up to 36 capacitive channels. The LCD drive supports segment displays directly. Housed in a 44-TQFP (10x10 mm) with 36 I/O brought out, this part is a surface-mount fit for standard reflow. Listed as Active by Infineon, so no last-time-buy risk for new designs. The part is ROHS3 compliant.","metaTitle":"CY8C4124AXI-443T PSoC 4 MCU, 24 MHz ARM Cortex-M0","metaDescription":"Infineon CY8C4124AXI-443T PSoC 4 MCU: ARM Cortex-M0 at 24 MHz, 16 KB Flash, 4 KB SRAM, 36 I/O, CapSense, 1.71 V to 5.5 V supply.","metaKeywords":null},"attributes":{"series":"PSOC® 4 CY8C4100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"24MHz","Series":"PSOC® 4 CY8C4100","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"4K x 8","Core Size":"32-Bit Single-Core","Peripherals":"Brown-out Detect/Reset, CapSense, LCD, LVD, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, Microwire, SmartCard, SPI, SSP, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"36","Core Processor":"ARM® Cortex®-M0","Package / Case":"44-LQFP","Data Converters":"A/D 8x12b SAR; D/A 2xIDAC","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":"44-TQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.47","priceTiers":[{"qty":1,"price":"$4.47000","currency":"USD"},{"qty":10,"price":"$4.01400","currency":"USD"},{"qty":25,"price":"$3.79520","currency":"USD"},{"qty":100,"price":"$3.28910","currency":"USD"},{"qty":250,"price":"$3.12040","currency":"USD"},{"qty":500,"price":"$2.79992","currency":"USD"},{"qty":1500,"price":"$2.36138","currency":"USD"},{"qty":3000,"price":"$2.24331","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2b4f8dee9139494317cb4172e8a50611.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY8C4124AXI-443T/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between CY8C4124AXI-443 and CY8C4124AXI-443T?","answer":"The suffix -T indicates Tape & Reel packaging.
