隨著擴(kuò)展塢產(chǎn)品的發(fā)展，許多客戶不得不面臨需要降低成本的需求，在方案中USB2.0 HUB芯片屬于不可或缺的的一部分，早些年基本采用的都是臺(tái)灣湯銘FE1.1S或者FE8.1，原廠提供有三種封裝形式SSOP28/SSOP16/QFN24。新域半導(dǎo)體推出的NS1.1S和NS8.1可以完美替代湯銘的料號(hào)，成本可以降低50%，讓我們一起看看芯片的簡(jiǎn)要描述。 1.0 Description Compliant to USB specification Revision 2.0 - Support 4/3/2 downstream ports by I/O pin configuration - Upstream port supports both high-speed (HS) and full-speed (FS) traffic- Downstream ports support HS, FS, and low-speed (LS) traffic On-chip 8-bit micro-processor -RISC-like architecture - USB optimized instruction set Single 'Transaction Translator (STT) - Single TT shares the same TT control logics for all downstream port devices. This is the most cost effective solution for TT. Multiple TT provides individual TT control logics for each downstream port.This is a performance better choice for USB 2.0 hub Integrate USB 2.0 transceiver Each downstream port supports two-color status indicator, with automatic and manual modes compliant toUSB specification Revision 2.0 可以提供免費(fèi)樣品進(jìn)行測(cè)試，行業(yè)標(biāo)桿客戶已經(jīng)大批量量產(chǎn)，蔡生18312533639 |
