Datasheet
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 (R
SET
) 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.
