TM1637 Datasheet

The data transmission of TM1637 has an acknowledgment signal ACK. When the transmitted data is correct, on the falling edge of the eighth clock, an acknowledgment signal ACK will be generated inside the chip to pull the DIO pin low, and the DIO will be released after the end of the ninth clock.

Description

The SH1106 is a single-chip CMOS OLED/PLED driver with controller for organic/polymer light emitting diode dot-matrix graphic display system. SH1106 consists of 132 segments, 64 commons that can support a maximum display resolution of 132 X 64. It is designed for Common Cathode type OLED panel. SH1106 embeds with contrast control, display RAM oscillator and efficient DC-DC converter, which reduces the number of external components and power consumption. This device is suitable for a wide range of compact portable applications, such as sub-display of mobile phone, calculator and MP3 player, etc.

Features

1. Support maximum 132 X 64 dot matrix panel

2. Embedded 132 X 64 bits SRAM

3. Operating voltage:

(1) Logic voltage supply: VDD1 = 1.65V – 3.5V

(2) DC-DC voltage supply: VDD2 = 3.0V – 4.2V

(3) OLED Operating voltage supply:
