MAX7219 LED Driver IC in DIP package

HCCOIC0037

New

The MAX7219 is a compact, serial input/output common-cathode display drivers that interfaces microprocessors (µPs) to 7-segment numeric LED displays of up to 8 digits, bar-graph displays, or 64 individual LEDs. Included on-chip are a BCD code-decoder, multiplex scan circuitry, segment and digit drivers, and an 8x8 static RAM that stores each digit. Only one external resistor is required to...

The MAX7219 is a compact, serial input/output common-cathode display drivers that interfaces microprocessors (µPs) to 7-segment numeric LED displays of up to 8 digits, bar-graph displays, or 64 individual LEDs. Included on-chip are a BCD code-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. The MAX7219 also allows the user to select code decoding or no-decode for each digit. The device includes a 150µA low-power shutdown mode, analogue and digital brightness control, a scan limit register that allows the user to display from 1 to 8 digits, and a test mode that forces all LEDs on.

♦ 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
♦ 24-Pin DIP Package



Arduino library:

If you intend to use this IC with an Arduino don't forget to check out our HC7219 library, which will allow you to effortlessly drive seven segment and 8x8 matrix LED's including the ability to daisy-chain IC's and create scrolling message displays. 

The library can be found in the software section of our support forum here: viewtopic.php?f=58&t=1794
