96 Segments with Common 3-Level Generic Display Driver

SSD1623 is a CMOS generic display driver with controller. It has 95 segments, 1 background segment and 1 common output. Each segment / common is capable of 3-voltage levels output.  It is designed with programmable display waveform which could match to many different display technology and applications.

SSD1623 equipped with SPI interface with hardware address map setting pin, allowing two or more SSD1623 connected to same SPI bus, increasing the available number of segments.  Flexible and power saving Charge pump is built in for generating high voltage (up to 38V) for panel driving.  VCI regulator is embedded to accept direct power supply from Lithium battery.

• 3-level output generic driver: V0, V1 and VSS. Each pin level can be individually programmed to V0, V1, VSS or Hi-Z (high impedance).

• Power supply: 

  • V_DD : 2.0 to 3.6V        (Logic opeartion)

  • V_DDIO: 2.0 to V_DD        (MCU interface)

  • V₀: 10 to 40V             (High voltage panel driving)

  • V_CI: 2.4 to 3.6V           (Charge pump and analog power supply)

  • V_BAT: 2.8 to 4.5V           (Li battery supply)

• VBAT can be supplied directly from Li-battery when optional VCI regulator is enable. 

• Lower power Charge pump with output programmable from 10 to 38V, in step of 1V

• Circuit selectable Charge pump multiplier ratio (16x, 12x, 8x, 6x, 4x)

• V0 can be supplied from internal Charge pump or external power supply

• Output channel

  • 95 segments (SEG[95:1])             for normal segment/icon driving

  • 1 background segment (SEG[0])    Background segment (4 times driving power) 

  • 1 common segment (COM)           Common signal

• 32-bit SPI interface with address map setting pin

• Dual frame display memory 96 x 2 bits, (Previous and Current)

• Built in oscillator or external clock inputs 

• Built in programmable frequency divider to divide external clock signal (4Mhz to 32 kHz) for IC operations

• Programmable output waveform in fitting different application or display requirement

• Battery voltage sensing
