TC9298F

The TC9298F is an LCD driver with on-chip key input, which is controlled using serial data.The segment/general-purpose output switching bits switch between segment output and general-purpose output. Setting 0 selects segment output; setting 1 selects general-purpose output.When segment output is selected, a display on/off waveform corresponding to the display data is output. When general-purpose output is selected, the general-purpose output control bit sets the output status.

Features of the TC9298F are:(1)supports switching between 1/4 and 1/8 duty and 1/3 and 1/4 bias; (2)displays up to 176 segments in 1/4 duty mode; up to 320 segments in 1/8 duty mode; (3)all display segments can be turned on or off. Outputs from the S40 to S43 pins can be switched between segment output and LED driver output; (4)supports input from 28 keys as standard. Externally connecting diodes supports input from up to 56 keys; (5)four-wire configuration employed for connecting to the controller.This bit sets the display on/off. In accordance with the setting, the waveform corresponding to display on/off is output to a segment output pin. Setting the bit to 1 outputs display on waveform; setting the bit to 0, display off waveform.

The absolute maximum ratings of the TC9298F can be summarized as:(1)supply voltage:-0.3 to 6.0 V;(2)input voltage:-0.3 to Vdd+0.3V;(3)storage temperature:-65 to 125;(4)operating temperature:-40 to 85;(5)power dissipation:300mW.TOSHIBA is continually working to improve the quality and the reliability of its products. Nevertheless, semiconductor devices in general can malfunction or fail due to their inherent electrical sensitivity and vulnerability to physical stress. It is the responsibility of the buyer, when utilizing TOSHIBA products, to observe standards of safety, and to avoid situations in which a malfunction or failure of a TOSHIBA product could cause loss of human life, bodily injury or damage to property. In developing your designs, please ensure that TOSHIBA products are used within specified operating ranges as set forth in the most recent products specifications.Also, please keep in mind the precautions and conditions set forth in the TOSHIBA Semiconductor Reliability Handbook.
