TUSB3410 and TUSB3410I are USB to Serial Port Controllers from Cypress Semiconductor that supports USB 2.0 and UART standards.
The TUSB3410 bridges a USB port to an enhanced UART serial port, integrating a 8052 microcontroller with 16 KB RAM, 10 KB ROM, and a built‑in two‑channel DMA controller. It supports USB 2.0 full‑speed (12 Mbps), multiple power modes, and a range of UART features including hardware flow control, RS‑485 transceiver control, and IrDA mode.
The manual includes a complete register map, memory map, electrical characteristics, and application notes such as crystal selection and wake‑up timing. It also details the bootcode programming flow, GPIO configuration, and I²C port usage for external memory access.
