Texas Instruments TUSB3410VFG4

TUSB3410VFG4 Description The TUSB3410 device provides bridging between a USB port and an enhanced UART serial port. The device contains an 8052 microcontroller unit (MCU) with 16KB of RAM that can be loaded from the host or from the external onboard memory through an I2C. The device also contains 10KB of ROM that allows the MCU to configure the USB port at boot time. The ROM code also contains an I2C bootloader. All device functions (such as the USB command decoding, UART setup, and error reporting) are managed by the internal MCU firmware in unison with the PC host.

TUSB3410VFG4 Features Fully Compliant With USB 2.0 Full-Speed Specifications: TID#40340262 Supports 12-Mbps USB Data Rate (Full Speed) Supports USB Suspend, Resume, and Remote Wake-Up Operations Configurable to Bus-Powered and Self-Powered Operation  Supports a Total of Three Input and Three Output (Interrupt, Bulk) Endpoints Integrated 8052 Microcontroller With: – 256 × 8 RAM for Internal Data – 10K × 8 ROM (With USB and I 2C Bootloader) – 16K × 8 RAM for Code Space Loadable From Host or I 2C Port – 2K × 8 Shared RAM Used for Data Buffers and Endpoint Descriptor Blocks (EDBs) – Master I 2C Controller for EEPROM Device Access – MCU Operates at 24 MHz, Providing 2-MIPS Operation – 128-ms Watchdog Timer
