Description

The STLED325 is a compact LED controller/

driver that interfaces microprocessors to LED

displays through serial I

LEDs connected in common anode configuration

and includes keyscanning for an 8 x 2 key matrix

which automatically scans and de-bounces a

matrix of up to 16 switches.

Furthermore, the STLED325 provides standby

power management to the host. It also integrates

a low-power, highly-accurate RTC and a remote-

control decoder. All functions are programmable

using the I

standby mode is achieved.

The STLED325 controller/driver is ideal as a

single peripheral device to interface the front

panel display with a single-chip host IC like CPU.
