The Densitron SDP-T694V-0 is a monochrome STN LCD display module built around the T6963C LSI controller. It integrates an 8-bit parallel data bus interface with full MPU compatibility, onboard 128-word character generator ROM, and support for up to 8KB external display RAM. The flexible memory architecture allows dynamic allocation between text, graphics, and custom character storage, with freely repositionable display windows. The module operates at 2.5V to 3.3V VCI and draws approximately 10mA at VCI=2.8V, FV=60Hz.
