What is the function of MAX232?
The MAX232 is an integrated circuit by Maxim Integrated Products that converts signals from a TIA-232 (RS-232) serial port to signals suitable for use in TTL-compatible digital logic circuits. The MAX232 is a dual transmitter / dual receiver that typically is used to convert the RX, TX, CTS, RTS signals.
What is MAX3232 and MAX232?
MAX232 is powered by 5V voltage, and max3232 is powered by 5V or 3.3V voltage. The power consumption of MAX232 is large, when the supply voltage is 5V, the power consumption is 5mA; while the power consumption of MAX3232 is small, when the supply voltage is 5V or 3.3V, the power consumption is 0.3mA.
What is MAX232 and RS232?
RS-232 is a serial communications standard from the Telecommunications Industry Association . MAX232 is an integrated circuit product from Texas Instruments that converts two full-duplex channels of logic-level signals (e.g. to and from a microcontroller) to RS232 communications voltage levels.
What is MAX3232?
MAX3232 IC is a converter IC, used to convert RD232 to TTL. This IC includes line drivers-2, line receivers-2 & a circuit for dual charge-pump including ESD protection from terminal to terminal with 15 kV.
What are RS232 voltage levels?
Valid RS-232 signals are either in the range of +3 V to +15 V or the range −3 V to −15 V with respect to the common ground (Figure 1-1). To be more specific, the driver output is Logic 0 when the voltage is between +5 V and +15 V and is Logic 1 when the voltage is between -5 V to -15 V.
What is meant by RS232?
Most people simply called it a serial connection. At one time, it was the most used form of data transmission. You will probably recognize the standard 9 pin DB9 cable. Simply put, a RS232 connection transmits signals using a positive voltage for a binary 0 and a negative voltage for a binary 1.
What is max232cpe?
The MAX232 device is a dual driver/receiver that includes a capacitive voltage generator to supply TIA/EIA-232-F voltage levels from a single 5-V supply. Each receiver converts TIA/EIA-232-F inputs to 5-V TTL/CMOS levels.
What is rs232c?
RS-232C is a long-established standard (“C” is the current version) that describes the physical interface and protocol for relatively low-speed serial data communication between computers and related devices.
What is RS232 in microcontroller?
Serial communication (also called RS232 communication) enables a microcontroller to be connected to another microcontroller or to a PC using a serial cable. Some microcontrollers have built-in hardware called USART (universal synchronous-asynchronous receiver-transmitter) to implement a serial communication interface.
What does 232 in RS232 stand for?
The term RS232 stands for “Recommended Standard 232” and it is a type of serial communication used for transmission of data normally in medium distances. It was introduced back in the 1960s and has found its way into many applications like computer printers, factory automation devices etc.
Is RS232 digital or analog?
technically, it is all analog (RS-232 uses voltage levels).
