PL2303 USB To RS232 TTL Converter Adapter Module/USB TTL Converter UART Module

Features: Module USB supply voltage: DC5V. USB 2.0 full speed compatible, low USB bandwidth consumption. Built-in 3.3V / 1.8V LDO regulator. Extended operating temperature range: -40C to 85C. 20-Pin -SSOP and QFN packages (RoHS compliant). Specifications: Material: Printed Circuit Board for UHCI / OHCI / EHCI host controllers. Integrated power-on-reset circuit. The data transfer rate is 1 megabyte per second. Each chip has a pre-programmed unique USB serial number. Supports bus-powered, self-powered and high-power bus-powered USB configurations. Built-in + 3.3V level shifter for USB I/O. Built-in + 3.3V level shifter for USB I/O. True 3.3V CMOS driver output and TTL input. (The operating voltage drops to 1V8 through an external pull-up resistor) The I/O voltage level is from 1.8V to 3.3V (withstand voltage to 5V). The drive current of the I/O pin can be configured. The entire USB protocol is processed on this chip and does not require USB-specific firmware programming. FT1248 serial parallel interface in 1, 2, 4, or 8-bit mode. Similar to the SPI slave 1-bit mode. Integrated 2048-byte multiple-programmable memory for storage device descriptions and CBUS I/O configuration. An integrated clock generator eliminates the need for an external crystal and has a clock output option for seamless connection to an external MCU or FPGA. A 512-byte receive buffer and a 512-byte transmit buffer enable high data throughput with buffering. Battery charger detection. Mobile devices can use it to detect the presence of a charger on the USB port for higher current/faster\ 8 mA (typ) of low operating current and 125 A (typ) of USB suspend current. Note: Please allow 1-2cm errors due to manual measurement,pls make sure that you do not mind before you mind.
