The TMP82C51AM-2 is a CMOS programmable communication interface (USART - Universal Synchronous/Asynchronous Receiver/Transmitter) manufactured by Toshiba. It facilitates serial communication between microprocessors and peripheral devices, supporting both synchronous and asynchronous protocols.

Applications

• Serial communication ports for computers and embedded systems
• Modems and other communication devices
• Printers and other serial peripherals
• Industrial control systems
• Data acquisition systems

Features

• Programmable serial communication modes: asynchronous and synchronous
• Full-duplex operation (simultaneous transmission and reception)
• Programmable baud rate generator (for asynchronous communication)
• Error detection capabilities: parity, overrun, and framing errors
• Modem control signals (CTS, RTS, DSR, DTR, RI)
• Single +5V power supply
• CMOS technology for low power consumption

Benefits

• Provides a flexible and configurable serial communication interface.
• Supports both asynchronous and synchronous communication methods.
• Simplifies the implementation of serial communication protocols.
• Enhances data integrity by detecting errors in transmission.
• Conserves power, making it suitable for battery-powered devices.

Additional Details

The TMP82C51AM-2 operates on a single +5V power supply and allows for full-duplex communication. The baud rate generator can be programmed to generate various baud rates for asynchronous communication. The device also supports synchronous communication with an external clock source. Error detection capabilities include parity, overrun, and framing errors. Modem control signals enable handshaking with modems and other communication devices. The '-2' likely refers to the speed grade or revision number. For accurate design and implementation, consulting the official Toshiba datasheet for this part is highly recommended to confirm electrical characteristics and timing specifications.
