MAX6951 - 5- and 8-Digit LED Display Drivers

General Description

The MAX6950/MAX6951 are compact common-cathode display drivers that interface microprocessors to individual 7-segment numeric LED digits, bar graph, or discrete LEDs through an SPI™-, QSPI™-, MICROWIRE™-compatible serial interface.

The supply voltage can be as low as 2.7V.

Key Features

  • High-speed 26MHz SPI-, QSPI-, MICROWIRECompatible Serial Interface.
  • +2.7V to +5.5V Operation.
  • Individual LED Segment Control.
  • Segment Blinking Control that Can Be Synchronized Across Multiple Drivers.
  • Hexadecimal Decode/No-Decode Digit Selection.
  • Digital Brightness Control.
  • Display Blanked on Power-Up.
  • Drives Common-Cathode LED Digits.
  • Multiplex Clock Syncronizable to External Clock.
  • Slew-Rate Limited Segm.

19-2227; Rev 2; 3/05 EVAALVUAAILTAIOBNLEKIT Serially Interfaced, +2.7V to +5.5V, 5- and 8-Digit LED Display Drivers MAX6950/MAX6951 General Description The MAX6950/MAX6951 are compact common-cathode display drivers that interface microprocessors to individual 7-segment numeric LED digits, bar graph, or discrete LEDs through an SPI™-, QSPI™-, MICROWIRE™-compatible serial interface. The supply voltage can be as low as 2.7V. The MAX6950 drives up to five 7-segment digits or 40 discrete LEDs. The MAX6951 drives up to eight 7-segment digits or 64 discrete LEDs. Included on-chip are hexadecimal character decoders (0–9, A–F), multiplex scan circuitry, segment and digit drivers, and a static RAM that stores each digit.
