CH340G (SMD SOP-16 Package) USB to Serial TTL Converter IC
CH340 is a series of USB bus adapters, that provides serial, parallel or IrDA interfaces over the USB bus (note: CH340G supports serial interface only). The CH340G integrate circuit provides common MODEM signals to allow adding a UART to a computer or converting existing UART devices to USB interface.
CH340g USB to TTL IC
As of now the CH340g is the cheapest USB to TTL IC in the market with very easy to solder foot print it has solder pitch of 1.27mm and SOIC16 package.
The?CH340 IC?does exactly what you would expect them to do: a full-speed USB device that emulates a standard serial interface, with speeds from 50bps to 2Mpbs. The chip supports 5V and 3.3V, and all the weird modem lines are supported.
Now a days lots of Node MCU, Arduino Nano and USB to TTL Converter Modules have been using this IC.
CH376S USB Read Write IC
CH376?is used as file manage control chip, used to MCU system read/write file in USB Flash Drive ?or SD card.
CH376 supports?USB-Device Mode?and?USB-HOST Mode. Set the basic firmware of?USB communication protocol in the inner. It is also set firmware of special communication protocol to ?deal with Mass-Storage devices, communication interface firmware of SD card, FAT16, FAT32 and?FAT12 file system manage firmware in the inner.
CM8870-PI
The CM8870PI provides full DTMF receiver capability by integrating both the bandsplit filter and digital decoder functions into a single 18-pin DIP. The filter section uses a switched capacitor technique for both high and low group filters and dial tone rejection. The CM8870 decoder uses digital counting techniques for the detection and decoding of all 16 DTMF tone pairs into a 4-bit code. This DTMF receiver minimizes external component count by providing an on-chip differential input ampli-fier, clock generator, and a latched three state interface bus. The on-chip clock generator requires only a low cost TV crystal or ceramic resonator as an external component.
