CYW55912IUBGTXTMA1

CYW55912IUBGTXTMA1 is the tape-and-reel orderable code (OPN) for the Infineon AIROC CYW55912 connected MCU in a WLBGA-143 package — a single-chip IoT processor combining a 192 MHz Arm Cortex-M33 with TrustZone, dual-band 1x1 Wi-Fi 6 (2.4/5 GHz, 20 MHz channels), Bluetooth Low Energy 5.4 with LE Long Range, 2 Mbps and advertising extensions, and 802.15.4. An integrated Wi-Fi PA delivers up to +24 dBm transmit power and BLE long-range sensitivity reaches -111.5 dBm, so one design covers both high-throughput cloud links and long-range sensor connections; 768 KB SRAM, 2 MB ROM, QSPI flash/PSRAM with XIP and on-the-fly encryption, and Matter over Wi-Fi support round out a platform aimed at smart home, industrial and wearable products. For product teams this removes the separate connectivity subsystem: the same device runs the application and both radios, cutting BOM count, board area and certification variants. Selection advice: choose the CYW55912 for dual-band designs; step up to the tri-band CYW55913IUBGTXTMA1 (also listed) when 6 GHz Wi-Fi 6E is required, and confirm the WLBGA-143 footprint and the external flash/PSRAM plan against the Infineon datasheet before layout. Parameters verified against the Infineon official product page, which lists this OPN as active and preferred.
