Serielt interface, 8-ciffer LED-display driver.
MAX7219 er en kompakt, seriel input/output fælleskatode display driver, der forbinder mikroprocessorer (µPs) til 7-segment numeriske LED-displays på op til 8 cifre, søjlediagram displays eller 64 individuelle LED'er. Med integreret BCD-kode-B-dekoder, multiplex scanningskredsløb, segment- og ciffer drivere og en 8x8 statisk RAM, der gemmer hvert ciffer. Der kræves kun én ekstern modstand for at indstille segmentstrømmen for alle LED'er. MAX7221 er kompatibel med SPI, QSPI og MICROWIRE og har slewrate-begrænsede segmentdrivere for at reducere EMI.

Serially Interfaced, 8-Digit LED Display Driver.
The MAX7219 is a compact, serial input/output common-cathode display driver that interface 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-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. The MAX7221 is compatible with SPI, QSPI, and MICROWIRE, and has slewrate-limited segment drivers to reduce EMI.
