All rights reserved. 02.Mar.2015 Rev.003 www.rohm.com TSZ22111・15・001 Pin Description Symbol Pin No. Function Active I/O Handling when unused S1/P1/G1 to S9/P9/G9 1 to 9 Segment output for displaying the display data transferred by serial data input. The S1/P1/G1 to S9/P9/G9 pins can also be used as General –purpose outputs when so set up by the control data. - O OPEN S10 to S77 10 to 77 Segment output for displaying the display data transferred by serial data input. - O OPEN KS1/S79 to KS6/S84 83 to 88 Key scan outputs Although normal key scan timing lines require diodes to be inserted in the timing lines to prevent shorts, since these outputs are unbalanced CMOS transistor outputs, these outputs will not be damaged by shorting when these outputs are used to form a key matrix. The KS1/S79 to KS6/S84 pins can be used as segment outputs when so specified by the control data. - O OPEN KI1/S85 to KI5/S89 89 to 93 Key scan inputs These pins have built-in pull-down resistors. The KI1/S85 to KI5/S89 pins can be used as segment outputs when so specified by the control data. - I/O OPEN COM1 to COM4 79 to 82 Common driver output pins. The frame frequency is fo[Hz]. - O OPEN COM5/S78 78 COMMON / SEGMENT output for LCD driving Assigned as COMMON output in1/5 Duty mode and SEGMENT output in 1/1 Duty, 1/3 Duty and 1/4 Duty modes - O OPEN OSC/S90 97 Segment output for displaying the display data transferred by serial data input. The pin OSC/S90 can be used as external frequency input pin when set up by the control data. - I/O OPEN SCE SCL SDI 98 99 100 Serial data transfer inputs. Must be connected to the controller. SCE: Chip enable SCL: Synchronization clock SDI: Transfer data H - I I I GND SDO 95 Output data - O OPEN VDD 94 Power supply pin of the IC A power voltage of 2.7V to 6.0V must be applied to this pin. - - - VSS 96 Power supply pin. Must be connected to ground. - - - ↑ |
