Flexible I/O Expander ICs

Toshiba offers a family of flexible I/O expander products, the TC35892XBG and the TC35890XBG. The flexible I/O expanders are designed to provide additional I/O ports enabling devices such as keypads, LEDs and rotator wheels to interface to the Baseband and/or application processor in a mobile handset or in other portable consumer electronic products.

Both devices address the mechanical and electrical design challenges associated with moveable parts in today's handheld consumer electronic products. The low-pin count, small-packaged devices offer up to 24 configurable, general-purpose I/O ports (GPIO) at needed locations and have built-in functionality for managing a keypad, PWM signal generation for LED and vibrator control and a rotator wheel interface.

The TC35892XBG features a smaller 3.5mm x 3.5mm x 1.2mm footprint compared to the TC35890XBG and an internal clock generator that is well suited for space-constrained handhelds. In addition, the TC35892XBG supports additional low-power features including operation from a low frequency clock source of 32 kHz, and clock-less operation that allows peripherals connected to the TC35892XBG to operate independently of the application processor for increased battery life.

New I/O Expanders Increase Functionality and Reliability

The TC35893XBG and TC35894XBG flexible I/O expander device are the company's newest additions to its mobile

peripheral device product portfolio. The TC35893XBG/TC35894XBG easily allow the addition of I/O peripheral ports so keypads, LEDs, and switches can interface seamlessly within a mobile handset or other portable consumer electronics device. Additionally, the TC35893XBG and TC35894XBG improve power efficiency in handheld devices and address the mechanical and electrical design challenges associated with moveable parts in advanced-feature mobile handsets.   Press Release
