2-Wire Interfaced, 2.7V to 5.5V, 4-Digit 5 ✕ 7
Matrix LED Display Driver
General Description
The MAX6953 is a compact cathode-row display driver
that interfaces microprocessors to 5 ✕ 7 dot-matrix LED
displays through an I2C™-compatible serial interface.
The MAX6953 drives up to four digits (140 LEDs).
Included on-chip are an ASCII 104-character font, mul-
tiplex scan circuitry, column and row drivers, and static
RAM that stores each digit, as well as font data for 24
user-definable characters. The segment current for the
LEDs is set by an internal digit-by-digit digital bright-
ness control.
The device includes a low-power shutdown mode, seg-
ment blinking (synchronized across multiple drivers, if
desired), and a test mode that forces all LEDs on. The
LED drivers are slew-rate limited to reduce EMI.
For an SPI™-compatible version, refer to the MAX6952
data sheet. An EV kit is available for the MAX6952.

LED Cathode Drivers. O0 to O13 outputs sink current from
the display’s cathode rows.
Ground
Segment Current Setting. Connect ISET to GND through
series resistor RSET to set the peak current.
Address Input 1. Sets device slave address. Connect to
either GND, V+, SCL, SDA to give four logic combinations.
See Table 3.
Not Connected
Blink Output. Output is open drain.
Multiplex Clock Input. To use internal oscillator, connect
capacitor CSET from OSC to GND. To use external clock,
drive OSC with a 1MHz to 8MHz CMOS clock.
Address Input 0. Sets device slave address. Connect to
either GND, V+, SCL, SDA to give four logic combinations.
See Table 3.

I2C-Compatible Serial Clock Input
LED Anode Drivers. O14 to O23 outputs source current to
the display’s anode columns.
Positive Supply Voltage. Bypass V+ to GND with a 47µF
bulk capacitor and a 0.1µF ceramic capacitor.
