Serially Interfaced, +2.7V to +5.5V,
5- and 8-Digit LED Display Drivers
General Description
The MAX6950/MAX6951 are compact common-cathode
display drivers that interface microprocessors to individ-
ual 7-segment numeric LED digits, bar graph, or discrete
LEDs through an SPI?-, QSPI?-, MICROWIRE?-com-
patible 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-seg-
ment 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. 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.
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
