The part integrates a 12-channel 14-bit ADC and a 4-channel 9-bit DAC on-chip, which cuts the analog front-end BOM for sensor conditioning or closed-loop control. Packaged in a 44-TQFP (10x10 mm) with 40 accessible I/O lines, it gives enough pins for parallel displays, keypads, or multiple sensor interfaces. ## Integrated analog — fewer external parts The 12-channel 14-bit ADC handles multiplexed analog inputs from thermistors, potentiometers, or current-sense resistors. The 4-channel 9-bit DAC can generate reference voltages or drive analog setpoints. For a control board that needs a few analog I/O channels, this PSoC 1 eliminates a separate ADC chip and a DAC chip, saving board space and procurement line items. ROHS3 compliance is confirmed, so it passes EU material restrictions without an exemption hunt.","metaTitle":"CY8C29566-24AXI PSoC 1 MCU, 8-bit M8C, 24 MHz, 32 KB Flash","metaDescription":"Cypress CY8C29566-24AXI PSoC 1 MCU: 8-bit M8C core at 24 MHz, 32 KB Flash, 2K x 8 RAM, 40 I/O, I²C/SPI/UART, 12x14b ADC, 4x9b DAC, -40°C to 85°C, 44-TQFP.","metaKeywords":null},"attributes":{"series":"PSOC®1 CY8C29xxx","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"24MHz","Series":"PSOC®1 CY8C29xxx","Package":"Tray","RAM Size":"2K x 8","Core Size":"8-Bit","Peripherals":"POR, PWM, WDT","Connectivity":"I²C, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"40","Core Processor":"M8C","Package / Case":"44-LQFP","Data Converters":"A/D 12x14b; D/A 4x9b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"44-TQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"3V ~ 5.25V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$15.97","priceTiers":[{"qty":1,"price":"$15.97000","currency":"USD"},{"qty":10,"price":"$14.67800","currency":"USD"},{"qty":25,"price":"$14.07000","currency":"USD"},{"qty":160,"price":"$12.39663","currency":"USD"},{"qty":320,"price":"$11.78822","currency":"USD"},{"qty":480,"price":"$11.02769","currency":"USD"},{"qty":960,"price":"$10.11505","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/41e27d09c10ee1914d734d8ae7d5fd22.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY8C29566-24AXI/alternatives.json"},"ai":{"faq":[{"question":"Does CY8C29566-24AXI support I2C, SPI, and UART interfaces?","answer":"Yes.
