MAX7219EWG+T

MAX7219 is a serially interfaced, 8-digit LED display driver. This is compact, serial input/output common-cathode display driver that interfaces microprocessor (μPs) to 7-segment numeric LED display of up to 8 digits, bar-graph displays, or 64 individual LEDs. Included on-chip are a BCD code-B decoder, multiplex scan circuitry, segment and digit drivers, and an 8x8 static RAM that stores each digit. Only one external resistor is required to set the segment current for all LEDs. A convenient 4-wire serial interface connects to all common μPs. Individual digits may be addressed and updated without rewriting the entire display. This also allow the user to select code-B decoding or no-decode for each digit. Application includes bar-graph displays, industrial controllers, panel meters, LED matrix displays.

• 10MHz serial interface, individual LED segment control
• Decode/no-decode digit selection, 150μA low-power shutdown (data retained)
• Digital and analogue brightness control, display blanked on power-up
• Drive common-cathode LED display
• Operating supply voltage range from 4.0 to 5.5V (V+ = 5V ±10%)
• 150µA shutdown supply current (max, all digital inputs at V+ or GND, TA = +25°C)
• 800Hz typical display scan rate (8 digits scanned, V+ = 5V ±10%)
• 5mA minimum segment drive sink current (segment off, VSEG = 0.3V)
• 3.0% typical segment drive current matching (V+ = 5V ±10%)
• 24 wide SO package, operating temperature range from -40°C to +85°C
