Description:
- Integrated serial input/output common cathode display driver can connect microprocessor to 8-digit 7-segment digital LED display or stick graph display or 64 independent LEDs.
- Includes an on-chip B-type BCD encoder, multi-scan circuit, segment word drive, and 8x8 static RAM used to store each data, and only one external register used to set segment current of each LED.
- The 4-wire serial interface can be connected to all common microprocessors and can be addressed for each data during updating without having to change all displays.
- Select or not each data 150μA low power shutdown mode: analog and digital brightness control, scanning limit register can display data from 1-8 bits, test mode: all LEDs are glowing.
Specifications:
- Size: Approx. 12.8 * 3.2 * 1.3 cm / 5.04 * 1.26 * 0.51 inch
- One module can drive common cathodes of 8x8 dot matrix.
- Operating Voltage: 5V
- Diameter 3mm, 64 hole fixing screws
- Supports modules with input and output interfaces, multiple modules cascading
- The input port is on the left side of the module and the output port is on the right side.
- If you only control one module, simply connect the input port to the CPU.
- If you want to connect the module, the input port of the first module connects the CPU, the output port of the second module connects the input port of the second module, the output port of the second module connects to the input port of the third module.
- 51 single chip Micyoco for example:
- VCC connects to 5V
D connects to D
- DIN connects to P2.2
- CS connects to P2.1
- CLK connects to P2.0
Package Includes:
