The M4 core runs at 150 MHz for signal processing and protocol stacks; the M0+ runs at 100 MHz for low-power background tasks and sensor polling. This lets you split the BLE stack onto one core and the application logic onto the other without a software scheduler fighting for cycles. ## 1 MB Flash, 288 KB SRAM — enough for OTA and complex stacks Program memory is 1 MB of Flash, backed by 288 KB of SRAM and an additional 32 KB of EEPROM. That SRAM allocation is generous for a wireless MCU at this tier — it leaves room for multiple BLE connection contexts, a large display buffer, or a file system cache without external memory. The EEPROM block is useful for persistent calibration or configuration data that needs byte-level rewrites without wear-leveling overhead. ## Peripheral set: Bluetooth, CapSense, USB, and a full complement of serial interfaces On-chip Bluetooth handles the wireless link; the CapSense block drives touch-sensing electrodes directly, eliminating a separate touch controller. The connectivity list includes I2C, LINbus, QSPI, SPI, UART/USART, and USB, plus I2S for digital audio and an LCD controller. With 78 GPIOs in a 116-ball BGA, you have enough pins to run a small TFT display, a keypad matrix, and several external sensors simultaneously. The package is a 116-ball WFBGA (5.2 x 6.4 mm body) that requires a standard BGA reflow profile; MSL is not listed in the record, so verify the moisture sensitivity level with the factory before opening the sealed tray.","metaTitle":"Infineon CY8C6347BZI-BLD53 PSoC 6 BLE MCU","metaDescription":"Infineon CY8C6347BZI-BLD53 PSoC® 6 BLE MCU: 32-bit ARM Cortex-M4/M0+, 1MB Flash, 288KB SRAM, Bluetooth, CapSense, 116-BGA.","metaKeywords":null},"attributes":{"series":"PSoC® 6 BLE","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Speed":"100MHz, 150MHz","Series":"PSoC® 6 BLE","Package":"Tray","RAM Size":"288K x 8","Core Size":"32-Bit Dual-Core","EEPROM Size":"32K x 8","Peripherals":"Bluetooth, Brown-out Detect/Reset, Cap Sense, DMA, I2S, LCD, POR, PWM, WDT","Connectivity":"I2C, LINbus, QSPI, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"78","Core Processor":"ARM® Cortex®-M4/M0","Package / Case":"116-WFBGA","Data Converters":"A/D 8x12b SAR; D/A 1x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Program Memory Size":"1MB (1M x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"116-BGA (5.2x6.4)","Voltage - Supply (Vcc/Vdd)":"1.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.81","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$13.81000","currency":"USD"},{"qty":10,"price":"$12.69000","currency":"USD"},{"qty":25,"price":"$12.16400","currency":"USD"},{"qty":80,"price":"$10.71738","currency":"USD"},{"qty":364,"price":"$10.19140","currency":"USD"},{"qty":728,"price":"$9.53390","currency":"USD"},{"qty":1092,"price":"$8.74488","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/1040a1eb432298b88e8ad57b7115c5f7.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY8C6347BZI-BLD53","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY8C6347BZI-BLD53 when reusing this data.
