Matrix LED Display Driver
General Description
The MAX6953 is a compact cathode-row display driver
that interfaces microprocessors to 5
鉁?/div>
7 dot-matrix LED
displays through an I
2
C鈩?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鈩?compatible version, refer to the MAX6952
data sheet. An EV kit is available for the MAX6952.
