Sanyo LC75813T Specifications

Page 1
Overview
The LC75813E and LC75813T are 1/3 duty and 1/4 duty general-purpose LCD drivers that can be used for frequency display in electronic tuners under the control of a microcontroller. The LC75813E and LC75813T can drive an LCD with up to 344 segments directly. The LC75813E and LC75813T can also control up to 8 general-purpose output ports. Since the LC75813E and LC75813T use separate power supply systems for the LCD drive block and the logic block, the LCD driver block power-supply voltage can be set to any voltage in the range 2.7 to 6.0 volts, regardless of the logic block power-supply voltage.
Features
• Switching between 1/3 duty and 1/4 duty drive techniques under serial data control.
• Switching between 1/2 bias and 1/3 bias drive techniques under serial data control.
• Up to 261 segments for 1/3 duty drive and 344 segments for 1/4 duty drive can be displayed.
• Serial data input supports CCB format communication with the system controller.
• Serial data control of the power-saving mode based backup function and all the segments forced off function.
• Serial data control of switching between the segment output port and the general-purpose output port functions.

Serial Data Transfer Example
1. 1/3 duty When 175 or more segments are used
All 312 bits of serial data must be sent.
When fewer than 175 segments are used
Either 104 or 208 bits of serial data may be sent, depending on the number of segments used. However, the serial data shown below (the D1 to D87 display data and the control data) must be sent.

Control Data Functions
1. P0 to P3: Segment output port/general-purpose output port switching control data. These control data bits switch the S1/P1 to S8/P8 output pins between their segment output port and general-purpose output port functions.
Note: Sn (n = 1 to 8): Segment output ports
Pn (n = 1 to 8): General-purpose output ports
Also note that when the general-purpose output port function is selected, the output pins and the display data will have the correspondences listed in the tables below.
For example, when 1/4 duty drive scheme is used, if the general-purpose output port function is selected for the S4/P4 output pin, that output pin will output a high level (V
LCD
) when the display data D13 is 1, and a low level
(VSS) when the D13 is 0.

The INH pin and Display Control
Since the IC internal data (1/3 duty: the display data D1 to D261 and the control data, 1/4 duty: the display data D1 to D344 and the control data) is undefined when power is first applied, applications should set the INH pin low at the same time as power is applied to turn off the display (This sets the S1/P1 to S8/P8, S9 to S86, COM1 to COM3, and COM4/S87 to the VSSlevel.) and during this period send serial data from the controller. The controller should then set the INH pin high after the data transfer has completed. This procedure prevents meaningless displays at power on. (See Figures 3 and 4.)
Notes on the Power On/Off Sequences
Applications should observe the following sequences when turning the LC75813E and LC75813T power on and off.
• At power on: Logic block power supply (VDD) on LCD driver block power supply (V
LCD
) on
• At power off: LCD driver block power supply (V
LCD
) off Logic block power supply (VDD) off
However, if the logic and LCD driver block use a shared power supply, then the power supplies can be turned on and off at the same time.

Notes on Controller Transfer of Display Data
Since the LC75813E and LC75813T accept the display data (D1 to D261) divided into three separate transfer operations when using 1/3 duty drive scheme and the data (D1 to D344) divided into four separate transfer operations when 1/4 duty drive, we recommend that applications transfer all of the display data within a period of less than 30 ms to prevent observable degradation of display quality.

This catalog provides information as of February, 2002. Specifications and information herein are subject to change without notice.
Specifications of any and all SANYO products described or contained herein stipulate the performance, characteristics, and functions of the described products in the independent state, and are not guarantees of the performance, characteristics, and functions of the described products as mounted in the customer’s products or equipment. To verify symptoms and states that cannot be evaluated in an independent device, the customer should always evaluate and test devices mounted in the customer’s products or equipment.
SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all semiconductor products fail with some probability. It is possible that these probabilistic failures could give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire, or that could cause damage to other property. When designing equipment, adopt safety measures so that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective circuits and error prevention circuits for safe design, redundant design, and structural design.
In the event that any or all SANYO products (including technical data, services) described or contained herein are controlled under any of applicable local export control laws and regulations, such products must not be exported without obtaining the export license from the authorities concerned in accordance with the above law.
