It shares the same ARM Cortex-M0 core at 48 MHz, the same 56-QFN 7x7 mm package, 36 I/O, and the same connectivity and peripheral set including Bluetooth and CapSense. The main difference is Flash size: 128 KB on the CY8C4247 versus 256 KB on the CY8C4248, and the ADC is 8x12b instead of 16x12b. If your firmware fits in 128 KB, it is a drop-in alternate."},{"question":"Does CY8C4248LQI-BL583T support Bluetooth 5.0?","answer":"No, the Bluetooth peripheral integrated in this MCU is Bluetooth 4.2 compliant. It does not support Bluetooth 5.0 features such as 2 Mbps PHY, long-range coding (Coded PHY), or extended advertising. For Bluetooth 5.0 capability, consider the PSoC 6 series (e.g. CY8C6137BZI-F54) which runs a Cortex-M4 at 150 MHz and includes a BLE 5.0 radio, though it is a different package and pinout."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY8C4248LQI-BL583T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY8C4248LQI-BL583T when reusing this data.
