The device integrates four independent UART channels, two of which can be independently configured as Multi-Protocol Synchronous Serial Engine (MPSSE) interfaces for JTAG, SPI, I2C, or bit-bang operation. The entire USB protocol is handled on-chip, eliminating the need for USB firmware development. The highly integrated design includes an internal +1.8 V LDO regulator for VCORE, an on-chip clock multiplier PLL (12 MHz to 480 MHz), and programmable I\/O drive strength. FTDI's royalty-free Virtual COM Port (VCP) and Direct (D2XX) drivers further simplify system integration.","working_principle":"The FT4232H connects to a USB host through its D+ and D- pins, handling all USB 2.0 High Speed protocol transactions internally. The internal PLL multiplies the 12 MHz external clock to 480 MHz for USB HS operation. Data received over USB is demultiplexed into one of four UART channels based on endpoint addressing. Channels A and B include MPSSE engines that translate USB commands into synchronous serial protocols (JTAG TCK\/TMS\/TDI\/TDO, SPI SCK\/MOSI\/MISO\/CS, I2C SCL\/SDA). Each UART channel has independent baud rate generators and 256-byte transmit\/receive FIFOs. The internal LDO generates 1.8 V for the core logic from the 3.3 V supply. Configurable EEPROM stores USB VID\/PID, serial number, and channel mode settings.","pin_description":"<table border=\"1\"><tr><th>Pin<\/th><th>Name<\/th><th>Description<\/th><\/tr><tr><td>1-8<\/td><td>AD0-AD7<\/td><td>Port A Data Bus (MPSSE\/UART)<\/td><\/tr><tr><td>9<\/td><td>GND<\/td><td>Ground<\/td><\/tr><tr><td>10<\/td><td>SI\/WUA<\/td><td>Send Immediate \/ Wakeup A<\/td><\/tr><tr><td>11<\/td><td>VCIO<\/td><td>Configurable I\/O Voltage<\/td><\/tr><tr><td>12<\/td><td>EECS<\/td><td>EEPROM Chip Select<\/td><\/tr><tr><td>13<\/td><td>EECLK<\/td><td>EEPROM Clock<\/td><\/tr><tr><td>14<\/td><td>EEDATA<\/td><td>EEPROM Data<\/td><\/tr><tr><td>15<\/td><td>DM<\/td><td>USB Data Minus<\/td><\/tr><tr><td>16<\/td><td>DP<\/td><td>USB Data Plus<\/td><\/tr><tr><td>17<\/td><td>VREGIN<\/td><td>Regulator Input (5V)<\/td><\/tr><tr><td>18<\/td><td>VCORE<\/td><td>Core Supply (1.8V from LDO)<\/td><\/tr><tr><td>19<\/td><td>TEST<\/td><td>Test Pin (tie to GND)<\/td><\/tr><tr><td>20<\/td><td>RESET#<\/td><td>Reset Input (Active Low)<\/td><\/tr><tr><td>21-28<\/td><td>BD0-BD7<\/td><td>Port B Data Bus (MPSSE\/UART)<\/td><\/tr><tr><td>29<\/td><td>SI\/WUB<\/td><td>Send Immediate \/ Wakeup B<\/td><\/tr><tr><td>30<\/td><td>PWREN#<\/td><td>USB Power Enable<\/td><\/tr><tr><td>31-38<\/td><td>CD0-CD7<\/td><td>Port C Data Bus (UART)<\/td><\/tr><tr><td>39<\/td><td>SI\/WUC<\/td><td>Send Immediate \/ Wakeup C<\/td><\/tr><tr><td>40-47<\/td><td>DD0-DD7<\/td><td>Port D Data Bus (UART)<\/td><\/tr><tr><td>48<\/td><td>SI\/WUD<\/td><td>Send Immediate \/ Wakeup D<\/td><\/tr><tr><td>49<\/td><td>SUSP#<\/td><td>USB Suspend Indicator<\/td><\/tr><tr><td>50<\/td><td>XTIN<\/td><td>Oscillator Input (12 MHz)<\/td><\/tr><tr><td>51<\/td><td>XTOUT<\/td><td>Oscillator Output<\/td><\/tr><tr><td>52-64<\/td><td>VCC\/GND<\/td><td>Power and Ground<\/td><\/tr><\/table>","application_scenarios":"<ul><li><b>FPGA\/CPU Debug Interfaces<\/b>: Quad JTAG\/SPI\/UART ports enable simultaneous programming and debugging of multiple devices<\/li><li><b>Industrial Gateways<\/b>: USB to multi-channel RS232\/RS485 bridges for factory communication systems<\/li><li><b>Embedded Development Boards<\/b>: On-board debug and console access via single USB connection<\/li><li><b>Consumer Electronics<\/b>: USB to multi-port serial expansion in set-top boxes and IoT gateways<\/li><li><b>Automotive Diagnostics<\/b>: Multi-protocol communication via MPSSE for ECU programming and testing<\/li><\/ul>","alternative_models":"<table border=\"1\"><tr><th>Model<\/th><th>Brand<\/th><th>Channels<\/th><th>Speed<\/th><th>MPSSE<\/th><\/tr><tr><td>FT2232HL<\/td><td>FTDI<\/td><td>2<\/td><td>480 Mb\/s<\/td><td>Yes (2)<\/td><\/tr><tr><td>FT232HL<\/td><td>FTDI<\/td><td>1<\/td><td>480 Mb\/s<\/td><td>Yes (1)<\/td><\/tr><tr><td>CH9344<\/td><td>WCH<\/td><td>4<\/td><td>12 Mb\/s<\/td><td>No<\/td><\/tr><tr><td>CP2105<\/td><td>Silicon Labs<\/td><td>2<\/td><td>12 Mb\/s<\/td><td>No<\/td><\/tr><tr><td>TUSB3410<\/td><td>TI<\/td><td>1<\/td><td>12 Mb\/s<\/td><td>No<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/8425","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/comments?post=8425"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/8425\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=8425"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=8425"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=8425"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=8425"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
