TUSB5052

The TUSB5052 is designed as one kind of USB to 2-serial port controller with configurable optional Hub that contains all the necessary logic to communicate with the host computer using the USB bus. In addition to the USB host interface, the device contains a 5-port hub that can be used for USB expansion.

Features of the TUSB5052 are:(1)Fully compliant with USB release 1.1 specifications; (2)Supports 12-Mbps USB data rate (full speed); (3)Supports USB suspend and resume operations; (4)One upstream port and five downstream ports (full and low speed); (5)Can support a total of 8 input endpoints and 8 output endpoints; (6)Dual-enhanced UARTs; (7)Supports external microcontroller interface for development ease; (8)Built-in four-channel DMA controller for USB/UART bulk I/O; (9)Operates from a 6-MHz crystal. On-chip PLL generates 48/24 MHz and 7.384615 MHz for internal baud-rate generator; (10)Power-down mode; (11)Available in 100-pin TQFP; (12)3.3/5-V operation

The absolute maximum ratings of the TUSB5052 can be summarized as:(1)Storage temperature range: -65°C to 150°C;(2)Output clamp current, IOK: ±20 mA;(3)Input clamp current: ±20 mA;(4)Output voltage range:0.5 V to Vcc+0.5 V;(5)Input voltage range:0.5 V to Vcc+0.5 V;(6)Supply voltage range:0.5 to 3.6 V.
