The MAX7219/MAX7221 are small, serial input/output common-cathode display drivers that connect microprocessors (Ps) to bar-graph displays, 64 individual LED displays, or 7-segment numeric LED displays with up to 8 digits. A BCD code-B decoder, multiplex scan circuitry, segment and digit drivers, and an 8×8 static RAM that saves every digit are all included on the device. To set the segment current for all LEDs, just one external resistor is needed. The MAX7221 incorporates slewrate-limited segment drivers to lower EMI and is compatible with SPITM, QSPITM, and MICROWIRETM.
MAX7219 IC
Original price was: ₨ 250.₨ 200Current price is: ₨ 200.
The MAX7219CNG IC is a newer version of the MAX7219 that is pin-compatible and has the same features, but it is also RoHS compliant and has a lower power consumption. The MAX7219CNG is a serial input/output common cathode display driver that interfaces microprocessors (µPs) to 7-segment numeric LED displays of up to 8 digits, bar-graph displays, or 64 individual LEDs.
