SCC2691AE1A28 General Description

The SCC2691AE1A28 ACE offered by NXP Semiconductors is a highly versatile and capable solution for asynchronous communications. Boasting two integrated serial communication channels, this device supports a variety of protocols, including UART, USART, and IrDA. Its built-in baud rate generator allows for operation at speeds of up to 1.5 Mbps, ensuring high performance across diverse applications. With a 4-byte FIFO buffer per channel, the ACE effectively minimizes CPU overhead for data handling, optimizing system efficiency. In addition, modem control signals for hardware flow control further enhance the device's utility in communication tasks. Operating within a power supply range of 4.5V to 5.5V, this ACE is well-suited for embedded applications, while its 28-pin SOIC package ensures compatibility with standard PCB layouts. With its robust design, low power consumption, and extensive feature set, the SCC2691AE1A28 is an excellent choice for communication needs in embedded systems, industrial automation, and telecommunications
