MaxLinear’s Carmel™ (MxL81434) high-speed USB-to-UART solution delivers 480 Mbps USB connectivity, four UART channels up to 15 Mbps each, integrated I²C, and 32 GPIOs for next-generation AI infrastructure console access.

Carmel™ extends MaxLinear’s USB-to-UART portfolio with a high-speed connectivity and console-access building block for server, rack-scale, and AI infrastructure designs.

We believe the market opportunity for USB-to-UART devices is substantial, with an estimated serviceable available market (SAM) of approximately 200 million units driven by AI data center deployments. Building on the success of Coronado™ and Laguna™, Carmel expands MaxLinear’s participation in this growing market by addressing higher-performance console-access, debug, monitoring, and infrastructure-management requirements for next-generation AI server and rack-scale platforms.

Why Carmel Matters

High-speed console access with up to 480Mbps High-Speed USB connectivity.
Four independent UART channels supporting up to 15Mbps per channel.
Integrated I²C and 32 GPIOs to consolidate management, monitoring, and debug functions.
Large 1024-byte transmit and receive FIFOs to help sustain throughput and reduce host overhead.
Robust ±15 kV HBM ESD protection for demanding server and data center environments.
Low-latency console connectivity to support faster bring-up, recovery, diagnostics, and provisioning.

Performance Leadership

Featuring four UART channels operating at speeds up to 15 Mbps each, Carmel provides high-speed console connectivity for data-intensive debug, provisioning, diagnostics, and recovery workflows.

The device integrates 1024-byte transmit and receive FIFOs, helping sustain high throughput while minimizing host processor overhead. An integrated I²C master and 32 GPIO channels allow designers to consolidate monitoring, reset management, debug access, and platform-management functions into a single device.
