MAX7219/MAX7221  
Serially Interfaced, 8-Digit LED Display Drivers  
General Description  
Features  
The MAX7219/MAX7221 are compact, serial input/out-  
put common-cathode display drivers that interface  
microprocessors (µPs) to 7-segment numeric LED dis-  
plays of up to 8 digits, bar-graph displays, or 64 indi-  
vidual 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 seg-  
ment current for all LEDs. The MAX7221 is compatible  
with SPI™, QSPI™, and MICROWIRE™, and has slew-  
rate-limited segment drivers to reduce EMI.  
♦ 10MHz Serial Interface  
♦ Individual LED Segment Control  
♦ Decode/No-Decode Digit Selection  
♦ 150µA Low-Power Shutdown (Data Retained)  
♦ Digital and Analog Brightness Control  
♦ Display Blanked on Power-Up  
♦ Drive Common-Cathode LED Display  
♦ Slew-Rate Limited Segment Drivers  
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/MAX7221 also allow the user to select code-  
B decoding or no-decode for each digit.  
for Lower EMI (MAX7221)  
♦ SPI, QSPI, MICROWIRE Serial Interface (MAX7221)  
♦ 24-Pin DIP and SO Packages  
The devices include a 150µA low-power shutdown  
mode, analog 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.
