64 LED Driver with Detailed Error Detection

1 General Description

2 Key Features

ꢀ

10MHz SPI-Compatible Interface

Open and Shorted LED Error Detection

- Global or Individual Error Detection

The AS1116 is a compact LED driver for 64 single LEDs

or 8 digits of 7-segments. The devices can be pro-

grammed via an SPI compatible 3-wire interface.

ꢀ

Hexadecimal- or BCD-Code for 7-Segment Displays

200nA Low-Power Shutdown Current (typ; data

retained)

Individual Digit Brightness Control

Digital and Analog Brightness Control

Display Blanked on Power-Up

Drive Common-Cathode LED Displays

Supply Voltage Range: 2.7 to 5.5V

Software Reset

Every segment can be individually addressed and

updated separately. Only one external resistor (RSET) is

required to set the current. LED brightness can be con-

trolled by analog or digital means.

ꢀ

The devices include an integrated BCD code-B/HEX

decoder, multiplex scan circuitry, segment and display

drivers, and a 64-bit memory. Internal memory stores

the shift register settings, eliminating the need for contin-

uous device reprogramming.

Optional External Clock

Package:

Additionally the AS1116 offers a diagnostic mode for

easy and fast production testing and allows the use of

the AS1116 for critical applications. The diagnostic

allows to detect individual open or shorted LEDs.

- QSOP-24 and TQFN(4x4)-24

3 Applications

The AS1116 is ideal for seven-segment or dot matrix dis-

plays in public information displays at subway, train or

bus stations, at airports and also at displays in public

The AS1116 features a low shutdown current of typically

200nA, and an operational current of typically 350µA.

The number of digits can be programmed, the devices

can be reset by software, and an external clock is also

supported.

transportation like buses or trains mobile phones, per-

The device is available in a QSOP-24 and TQFN(4x4)-

24 package.
