Product Summary

The MAX7221EWG is a compact, serial input/output common-cathode display driver that interface microprocessor (μP) 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 MAX7221CWG is compatible with SPI, QSPI, and Microwire, and has slew-ratelimited segment drivers to reduce EMI.
