FTDI FT4232HL USB to RS232/RS485/RS422/UART/JTAG/SPI and I2C
The FTDI chip that allows your microcontroller to communicate to your PC. Commonly used for Arduino Nano series microcontrollers or standalone Atmel and Pic Microcontrollers. This specific product is similar to the FTDI chip, however it is on steroids. Allowing not only the generic serial communication protocol, it offers RS232, RS485, RS422 and JTAG options.
Chip Feature:
- Highly integrated design includes +1.8V LDO regulator for VCORE, integrated POR function and on chip clock multiplier PLL (12MHz – 480MHz).
- FTDI FT232B style, asynchronous serial UART interface option with full hardware handshaking and modem interface signals.
- Fully assisted hardware or X-On / X-Off software handshaking.
- UART Interface supports 7/8 bit data, 1/2 stop bits, and Odd/Even/Mark/Space/No Parity.
- Auto-transmit enable control for RS485 serial applications using TXDEN pin.
- Operational configuration mode and USB Description strings configurable in external EEPROM over the USB interface.
- Low operating and USB suspend current.
- Configurable I/O drive strength (4,8,12 or 16mA) and slew rate.
- Supports bus powered, self powered and high- power bus powered USB configurations.
- UHCI/OHCI/EHCI host controller compatible.
- USB Bulk data transfer mode (512 byte packets in High Speed mode).
- Dedicated Windows DLLs available for USB to JTAG, USB to SPI, and USB to I2C applications.
- +1.8V (chip core) and +3.3V I/O interfacing (+5V Tolerant).
- Extended -40°C to 85°C industrial operating temperature range.
- Compact 64-LD Lead Free LQFP or QFN package
- +3.3V single supply operating voltage range.
- ESD protection for FT4232H IO’s:
- Human Body Model (HBM) ±2kV, Machine Mode (MM) ±200V, Charge Device Model (CDM) ±500V, Latch-up free.
Typical Applications:
- Single chip USB to four channels UART (RS232, RS422 or RS485) or Bit-Bang interfaces.
