OLED/PLED Segment/Common Driver with Controller

SSD1327 displays data directly from its internal 128 x 128 x 4 bits Graphic Display Data RAM (GDDRAM). Data/Commands are sent from general MCU through the hardware selectable I²C Interface, 6800-/8080-series compatible Parallel Interface or Serial Peripheral Interface.

• Resolution: 128 x 128 matrix panel

• 262k color depth supported by embedded 128x128x18 bit SRAM display buffer

• Power supply 

  • V_CC= 8V - 18V       (Panel driving power supply)

  • V_CI= 1.65V - 3.5V   (MCU interface logic level & low voltage power supply)

  • V_DD= 1.65V - 2.6V  (Core V_DD power supply, details refer to Table 2-1)

            Table 2-1 V_CI and V_DD range

  	VCI	VDD	Remarks
  	1.65 V ~ 2.6V	1.65V ~ 2.6V	VDD should be tied to VCI and supplied by external power source
  	2.6V ~ 3.5V	2.4V ~ 2.6V	VDD is regulated from VCI

  •  V_CI must be higher than or equivalent to V_DD at any circumstance

• For matrix display

  • Segment maximum source current: 300µA

  • Common maximum sink current: 40mA

  • 256 step contrast brightness current control

• Embedded 128 x 128 x 4 bit SRAM display buffer

• 16 gray scale

• Pin selectable MCU Interfaces

  • 8-bit 6800/8080-series parallel interface

  • 3/4-wire Serial Peripheral Interface

  • I²C Interface

• Screen saving continuous scrolling function in both horizontal and vertical direction

• Programmable Frame Rate

• Programmable Multiplexing Ratio

• Row Re-mapping and Column Re-mapping

• On-chip Oscillator

• Power On Reset (POR)

• Chip layout for COG, COF

• Wide range of operating temperature: -40ºC to 85ºC
