4-Wire Serially Interfaced

8 x 8 Matrix Graphic LED Drivers

General Description

Features

The MAX6960–MAX6963 are compact cathode-row dis-

play drivers that interface microprocessors to 8 x 8 dot-

matrix red, green, and yellow (R,G,Y) LED displays

through a high-speed 4-wire serial interface.

♦ 2.7V to 3.6V Operation

♦ High-Speed 20MHz Serial Interface

♦ Trimmed 40mA or 20mA Peak Segment Current

♦ Directly Drives Either Two Monocolor or One RGY

Cathode-Row 8 x 8 Matrix Displays

♦ Analog Digit-by-Digit Segment Current Calibration

♦ Digital Digit-by-Digit Segment Current Calibration

♦ 256-Step Panel Intensity Control (All Drivers)

♦ Four Steps per Color Pixel-Level Intensity Control

♦ Open/Short LED Detection

The MAX6960–MAX6963 drive two monocolor 8 x 8

matrix displays, or a single RGY 8 x 8 matrix display with

no external components. The driver can also be used

with external pass transistors to control red, green, blue

(RGB) and other displays at higher currents and voltages.

The MAX6960–MAX6963 feature open- and short-circuit

LED detection, and provide both analog and digital tile

segment current calibration to allow 8 x 8 displays from

different batches to be compensated or color matched.

♦ Burst White to Display Memory Planes

A local 3-wire bus synchronizes multiple interconnected

MAX6960–MAX6963s and automatically allocates memory

map addresses to suit the user’s display-panel

architecture.

♦ Global Command Access All Devices

♦ Can Control RGB Panels or Higher

Current/Voltage Panels with External Pass

Transistors

The MAX6960–MAX6963s’ 4-wire interface connects mul-

tiple drivers, with display memory mapping shared and

allocated among the drivers. A single global write opera-

tion can send a command to all MAX6960s in a panel.

♦ Multiple Display Data Planes Ease Animation

♦ Automatic Plane Switching from 63 Planes per

Second to One Plane Every 63s, with Interrupt

♦ Slew-Rate-Limited Segment Drivers for Lower EMI

The MAX6963 drives monocolor displays with two-step

intensity control. The MAX6962 drives monocolor displays

with two-step or four-step intensity control. The MAX6961

drives monocolor or RGY displays with two-step intensity

control. The MAX6960 drives monocolor or RGY displays

with two-step or four-step intensity control.

♦ Driver Switching Timing Can Be Spread Between

Multiple Drivers to Flatten Power-Supply Peak

Demand

♦ Low-Power Shutdown with Full Data Retention

♦ -40°C to +125°C Temperature Range
