NXP Semiconductors 2691 series Serial I/O Controller, part number 2691-B3A, offers a single-channel asynchronous serial interface with a maximum data transfer rate of 0.125 Mbps. This CMOS device operates with a supply voltage range of 4.5V to 5.5V, nominal 5.0V, and supports a wide operating temperature range from -55°C to +125°C. It features NRZ encoding/decoding and utilizes a 28-terminal Ceramic Quad Flat Pack (CQFP) package, specifically a metal-sealed cofired CERAMIC, METAL-SEALED COFIRED package with a terminal pitch of 1.270 mm. The 2691-B3A is suitable for applications requiring robust serial communication, including industrial automation and legacy system interfaces. Its low-power mode capability further enhances its utility in power-sensitive designs.
