Maxim MAX7219CNG+

LED7 段 + DP4 线串行

Overview

The MAX7219 / MAX7221 are compact, serial input/output common-cathode display drivers 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 8×8 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.
