CY8C22345-24SXIT carries an active lifecycle status. At 24 MHz the M8C core executes one instruction per two clock cycles in most cases. ## Package and footprint: 28-SOIC wide-body The 28-SOIC (0.295\", 7.50 mm width) package is a surface-mount wide-body SOIC. The 24 I/O are accessible on standard 1.27 mm pitch. Supply decoupling should follow the PSoC1 layout guidelines: a 0.1 µF ceramic close to each Vdd/Vss pair, plus a bulk 10 µF capacitor near the package. The internal POR and LVD peripherals reduce external supervisor IC requirements.","metaTitle":"Cypress CY8C22345-24SXIT PSoC1 MCU, 8-Bit M8C 24 MHz","metaDescription":"CY8C22345-24SXIT PSoC1 MCU: 8-bit M8C core at 24 MHz, 16 KB Flash, 1 KB SRAM, 24 I/O, I²C/SPI/UART, 3x10b ADC, -40°C to 85°C.

The CY8C22345-24SXI is the Tube-packaged variant. Both share the same silicon, 28-SOIC package, and electrical ratings. They are electrically identical; the only difference is the shipping medium."},{"question":"Does CY8C22345-24SXIT require an external crystal for operation?","answer":"No. The CY8C22345-24SXIT has an internal oscillator, so it can operate without an external crystal. If tighter timing accuracy is needed, an external clock source can be used."},{"question":"Is CY8C22345-24SXIT ROHS compliant?","answer":"Yes, the CY8C22345-24SXIT is ROHS3 compliant."},{"question":"What is the closest functional second-source for CY8C22345-24SXIT?","answer":"Within the PSoC1 family, the CY8C29566-24AXIT offers a similar M8C core at 24 MHz but with more I/O (40), 12x14-bit ADC channels, and 4x9-bit DACs in a 44-pin TQFP package. It is a step up in analog capability and I/O count, not a pin-compatible drop-in. For a direct socket-compatible alternative with the same 28-SOIC footprint and 24 I/O, the CY8C29466-24PVXI is a closer match but differs in ADC resolution (12x14b vs 3x10b) and package (SSOP vs SOIC). Neither is an exact second-source; both require a board respin."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY8C22345-24SXIT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY8C22345-24SXIT when reusing this data.
