1 General Description

The AS1115 is a compact LED driver for 64 single LEDs

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

grammed via an I²C compatible 2-wire interface.

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.

All outputs of the AS1115 can be configured for key

readback. Key-switch status is obtained by polling for up

to 64 keys while 16 keys can be used to trigger an inter-

rupt.

Additionally the AS1115 offers a diagnostic mode for

easy and fast production testing.

The AS1115 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.

The device is available in a QSOP-24 and the

TQFN(4x4)-24 package.
