It packs 32 KB of Flash program memory and 2K x 8 of SRAM — enough for moderate embedded control firmware without external storage. 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. Serial connectivity covers I²C, SPI, and UART/USART, so it talks to common peripherals without extra glue logic. 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. The internal oscillator eliminates an external crystal for basic timing, though the peripheral set includes POR, PWM, and WDT for system supervision. ## 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. ## Active lifecycle — no LTB pressure The CY8C29566-24AXI carries an Active product status. 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":["Discrete Semiconductors"],"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","stockQuantity":0,"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},"ai":{"faq":[{"question":"Does CY8C29566-24AXI support I2C, SPI, and UART interfaces?","answer":"Yes.
