The USB2642 is a USB 2.0 compliant, hi-speed huband card reader combo solution. This fully-integrated, single chip solution provides USB expansion and flash media reader/writer integration. The Microchip USB2642 provides an ultra fast interface between a USB host and today’s popular flash media formats. The controller allows read/write capability to flash media including the following:
? Secure DigitalTM (SD)
? SD High CapacityTM (SDHC)
? SD Extended CapacityTM (SDXC)
??MultiMediaCardTM (MMC)
? Embedded MultiMediaCard (eMMC)
The USB2642 offers a versatile, cost-effective and energy-efficient hub controller with 2 downstream USB 2.0 ports and a flash media interface. The flash media interface can support sustained transfer rates exceeding 35 MB/s.? Additionally, the USB2642 provides an I2CTM over USB bridge and an SD over USB bridge. The I2C bridge allows for control of any I2C slave device operating at 50KHz serial clock, while the SD bridge supports the use of SDIO cards.
*The? service is subject to?Microchip'sand requires a myMicrochip?account.

深入剖析CC2642R-Q1：藍(lán)牙低功耗無(wú)線MCU的卓越之選 在當(dāng)今的電子設(shè)備領(lǐng)域，無(wú)線通信技術(shù)的發(fā)展日新月異，低功耗、高性能的無(wú)線微控制器（MCU）成為了眾多應(yīng)用的核心選擇。CC2642
TI CC2642R BLE 5.2 低功耗藍(lán)牙模塊 憑借其卓越性能與靈活應(yīng)用，正重新定義無(wú)線通信的邊界。本文將從技術(shù)特性、核心優(yōu)勢(shì)、應(yīng)用場(chǎng)景及開(kāi)發(fā)支持四大維度，深度解析這款模塊如何賦能行業(yè)創(chuàng)新。 一、技術(shù)特性：BLE 5.2時(shí)代的標(biāo)桿之作 1.? 高速傳輸與遠(yuǎn)距離通
隨著技術(shù)的發(fā)展，USB（通用串行總線）接口已經(jīng)成為連接電子設(shè)備的標(biāo)準(zhǔn)。從最初的 USB 1.0 到現(xiàn)在的 USB 4.0，USB 接口經(jīng)歷了多次迭代，以適應(yīng)不斷增長(zhǎng)的數(shù)據(jù)傳輸速度和電力傳輸需求
通用串行總線（USB）正迅速成為大部分PC外設(shè)的標(biāo)準(zhǔn)接口。由于它具有出色的速度、靈活性，并且支持設(shè)備熱插拔，因而正在取代RS232和并行打印機(jī)端口。工業(yè)和醫(yī)療設(shè)備制造商也非常希望使用這種總線，但苦于沒(méi)有很好的方式...
USB-C和USB Type-C是同一種標(biāo)準(zhǔn)，用于連接電子設(shè)備和傳輸數(shù)據(jù)、音頻和視頻信號(hào)。USB-C是USB Type-C的簡(jiǎn)稱，兩者可以互換使用。USB-C是USB協(xié)會(huì)于2014年發(fā)布的最新一代
USB On-the-Go （OTG） 允許兩個(gè) USB 設(shè)備相互通信，而無(wú)需個(gè)人計(jì)算機(jī)的服務(wù)。盡管 OTG 似乎將“點(diǎn)對(duì)點(diǎn)”連接添加到 USB，但事實(shí)并非如此。相反，USB OTG 保留了標(biāo)準(zhǔn)
RF-BM-2642QB1I是信馳達(dá)基于TI車規(guī)藍(lán)牙SoC CC2642R-Q1設(shè)計(jì)的一款低功耗藍(lán)牙5.2模塊, 采用Arm?Cortex?-M4F處理器，具有352 KB Flash和88 KB RAM，工作溫度支持-40℃~ 105℃，符合AEC-Q100汽車規(guī)格等級(jí)2，面向低功耗藍(lán)牙5汽車應(yīng)用。
TI公司的CC2642R是SimpleLink? Bluetooth? 5低功耗無(wú)線MCU，具有成本效率超低功耗，2.4GHz和亞GHz RF器件，具有非常低的工作RF和微處理器（MCU）電流，以及亞μA睡眠電流和高達(dá)80KB奇偶保護(hù)的RAM，具有極好電池壽命，允許用小型鈕扣電池...
