Features
• Four members of the SBN1661G_X series:
– the SBN1661G_M18,
– the SBN1661G_M02,
– the SBN0080G_S18, and
– the SBN0080G_S02
• 16 COMMON, 61 SEGMENT STN LCD driver (the SBN1661G_M18 and the SBN1661G_M02).
• 80 SEGMENT STN LCD driver for expanding segment number (the SBN0080G_S18 and the SBN0080G_S02).
• On-chip Display Data Memory: 32-row x 80-column (totally 2560 bits).
• Dot Matrix Mapping between the Display Data Memory bit and LCD pixel.
• A “0” stored in the Display Data Memory bit corresponds to an OFF-pixel on the LCD panel; a “1” stored in the Display
Data Memory bit corresponds to an ON-pixel on the LCD panel.
• 5-level external LCD bias.
• Display duty cycle: 1/16, 1/32 for all four devices.
• Two types of interface timing with a host microcontroller: the 80-type microcontroller and the 68-type microcontroller.
• Dual function RESET/IF input for chip reset and selection of microcontroller interface timing.
• 8-bit parrallel data bus; READ, WRITE, CHIP SELECT control bus.
• A set of internal registers: Display ON/OFF, Display Start Line, Static Drive ON/OFF, Memory Page Address, Memory
Column Address, Duty Selection, Memory Column/Segment mapping, and Status.
• Display Data Read/Write commands and Software Reset command.
• Read-Modify-Write command for block data transfer from the host microcontroller to the Display Data Memory.
• Power-saving mode.
• On-chip RC-type oscillator, requiring only an external resistor (the SBN1661G_M18).
• Operating voltage range (V
DD): 2.7 ~ 5.5 volts.
• LCD bias voltage (V
LCD=V5-VDD): -13 volts (max.).
• Operating frequency range: 2 KHz, 18 KHz.
• Operating temperature range: -20 to +75 °C.
• Storage temperature range: -55 to +125 °C.
