This SKU 382487 is available in DXSOUL with Free Expedited delivery. DXSOUL: 901382487

Introduction:



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 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 slew-ratelimited segment drivers to reduce EMI.

A convenient 3-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.

The devices include a 150μA low-power shutdownmode, analog and digital brightness control, a scanlimitregister that allows the user to display from 1 to 8digits, and a test mode that forces all LEDs on.

Wiring instructions:

VCC → 5V

GND → GND

DIN → P1.0

CS → P1.1

CLK → P1.2

Note:

1.VCC and GND Do not reversed, it would burn the chip;

2. Use the old 51 microcontroller port P0 pull-up resistor required.
