The MAX6950/MAX6951 are compact common-cath-

ode 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.

♦ High-speed 26MHz SPI-, QSPI-, MICROWIRE-

Compatible Serial Interface

♦ +2.7V to +5.5V Operation

♦ Individual LED Segment Control

♦ Segment Blinking Control that Can Be

The MAX6950 drives up to five 7-segment digits or 40

discrete LEDs. The MAX6951 drives up to eight 7-seg-

ment digits or 64 discrete LEDs.

Synchronized Across Multiple Drivers

♦ Hexadecimal Decode/No-Decode Digit Selection

♦ Digital Brightness Control

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. The

user may select hexadecimal decoding or no-decode

for each digit to allow any mix of 7-segment digits, bar

graph, or discrete LEDs to be driven. The segment cur-

rent for the LEDs is set by an internal digital brightness

control. The segment drivers are slew-rate limited to

reduce EMI.

♦ Display Blanked on Power-Up

♦ Drives Common-Cathode LED Digits

♦ Multiplex Clock Syncronizable to External Clock

♦ Slew-Rate Limited Segment Drivers for Low EMI

♦ 75µA Low-Power Shutdown (Data Retained)

♦ Small 16-Pin QSOP Package

Individual digits may be addressed and updated with-

out rewriting the entire display. The devices include a

low-power shutdown mode, digital brightness control, a

scan-limit register that allows the user to display from

one to eight digits, segment blinking that can be syn-

chronized across drivers, and a test mode that forces

all LEDs on.
