Part Number: TUSB4020BI HI TI Support team,
客户咨询如下问题:
产品内置了 TUSB4020BIP ,再把USB转TTL,但是假如此时有一个行为长时间把 TUSB4020BIP 的USB的D+/-短接在一起,这种行为是否会存在损坏 TUSB4020BIP的风险呢,假如我又把短接的行为去掉了,再去使用 TUSB4020BIP的USB2.0的相关功能,此时是否会出现无法识别USB的情况呢?
TUSB4020BIP is built into the product…
In theory, USB has enough bandwidth for 64k samples per second. In practice, this depends on what protcol you use and how the MCU firmware is implemented, and I guess there will be a latency of at least one USB frame for each step in the chain.
