Features & Applications

This dual-channel product family is highly integrated and built for small board space, low voltage and high bandwidth requirements found in a variety of handheld and battery operated applications. These include Point-of-Sale (POS) terminals, tablets and notepads, CDMA cellular phones, expansion modules, instrumentation, cellular base stations, wireless infrared appliances and industrial automation controls.

The series consists of four devices: XR16L2450, XR16L2550, XR16L2551 and XR16L2552. Each has two independently controlled UART channels and operates over a broad range power source of 2.25V to 5.5V with 5V tolerant inputs.

The XR16L2551 uniquely offers a very small 32-QFN, 5x5x0.9mm, package with PowerSave feature to conserve power down to less than 30uA* of current consumption. These attributes are a perfect combination for tight space and/or battery operated designs. The PowerSave feature eliminates the need for two external octal transceivers to reduce board space requirement and lower overall system costs. The XR16L2551 also offers a pin select for Intel or Motorola data bus interface to reduce hardware design cycle.

The XR16L2550, XR16L2551 and XR16L2552 have 16-byte of TX and RX FIFOs for larger data buffering and provide automatic hardware (RTS/CTS) or software (Xon/Xoff) flow control to eliminate receiver data overflow and wasteful re-transmissions. In addition, the devices include the wireless infrared encoder/decoder for wireless communications. The XR16L2450 has one byte of TX and RX FIFO as its predecessor, the ST16C2450, but with lower operating voltage and 5V tolerant inputs. The 4 devices are pin and function compatible with their previous 5V series
