The part integrates Bluetooth LE, capacitive touch sensing (CapSense), LCD drive, and a 16-channel 12-bit SAR ADC plus two IDACs, making it a single-chip solution for wireless sensor nodes and human-machine interfaces. ## 48 MHz Cortex-M0 — throughput and timing The 48 MHz core clock is the performance ceiling for this device. At this speed, the Cortex-M0 executes most single-cycle instructions, and the Flash controller requires zero wait states for aligned 32-bit reads up to 48 MHz — no wait-state configuration needed unless you push beyond. For BLE stack + application code, the 256 KB Flash leaves room for the Bluetooth stack plus a modest application; the 32 KB SRAM handles BLE packet buffers and a few kilobytes of sensor data. If your application needs more than 32 KB of RAM for large frame buffers or complex analytics, step up to the PSoC 6 family. ## Integrated Bluetooth and CapSense — peripheral fit The 36 GPIOs in the 56-QFN package provide enough pins for a small keypad, a few LEDs, and sensor inputs while leaving serial lines free. The 16-channel 12-bit SAR ADC samples at up to 1 Msps (typical), adequate for most sensor readouts. The two IDACs can generate analog reference currents or drive external loads without an external DAC. Infineon lists the CY8C4248LQI-BL583 as Active (current production). This part is suitable for qualification into new designs without an imminent obsolescence risk. For dual-sourcing, the CY8C4247LQI-BL473 is a pin-compatible sibling with 128 KB Flash and 8x12b ADC — a drop-in for lower memory or ADC channel count needs.","metaTitle":"Infineon CY8C4248LQI-BL583 PSoC 4 BLE MCU, 48MHz Cortex-M0","metaDescription":"Infineon CY8C4248LQI-BL583 PSoC 4 BLE MCU: ARM Cortex-M0 at 48MHz, 256KB Flash, 32KB SRAM, Bluetooth, CapSense, 16x12b ADC, 1.71V-5.5V, -40°C to 85°C, 56-QFN.","metaKeywords":null},"attributes":{"series":"PSOC® 4 CY8C4xx8 BLE","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Speed":"48MHz","Series":"PSOC® 4 CY8C4xx8 BLE","Package":"Tray","RAM Size":"32K x 8","Core Size":"32-Bit Single-Core","Peripherals":"Bluetooth, Brown-out Detect/Reset, Cap Sense, DMA LCD, LVD, POR, PWM, SmartCard, SmartSense, 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":"56-UFQFN Exposed Pad","Data Converters":"A/D 16x12b SAR; D/A 2xIDAC","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"56-QFN (7x7)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.32","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$8.32000","currency":"USD"},{"qty":10,"price":"$7.51300","currency":"USD"},{"qty":25,"price":"$7.16400","currency":"USD"},{"qty":80,"price":"$6.22038","currency":"USD"},{"qty":260,"price":"$5.94081","currency":"USD"},{"qty":520,"price":"$5.41663","currency":"USD"},{"qty":1040,"price":"$4.71771","currency":"USD"}]},"links":{"datasheetUrl":"https://www.infineon.com/cms/en/about-infineon/company/contacts/support/?utm_source=cypress&utm_medium=referral&utm_campaign=202110_globe_en_all_integration-files","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between CY8C4248LQI-BL583 and CY8C4247LQI-BL473?","answer":"The CY8C4247LQI-BL473 is a pin-compatible sibling with half the Flash (128 KB vs 256 KB) and an 8-channel 12-bit SAR ADC instead of 16 channels.
