STLED316S

Serial-Interfaced 6-Digit LED controller with key scan

Data Brief

Features

■ LED driver with 14 outputs (8 segments

/ 6 digits)

■ 40mA load current capability for each segment

■ Outputs connect directly to the LEDs or can be

open-drain

SO-24

■ Key-scanning (8x2 matrix)

■ Low power consumption in standby mode

■ 3-wire Serial Bus Interface (CLK, STB,

DIN/DOUT)

Description

■ 8-step dimming circuit to control the overall

The STLED316S is a compact LED controller and

driver that interface microprocessors to LED

displays through serial 3-wire interface. It drives

LED connected in common anode configuration.

The STLED316S drives up to 48 discrete LEDs in

8 segment/6 digit configuration while functioning

from a supply voltage of 5.0V. Additionally it can

be used to drive 8 discrete LEDs which form a

part of LED digit. The individual LEDs are wired

as segments of a digit and brightness of these

individual LEDs can be controlled digitally. The

maximum segment current for the display digits is

set through a single external resistor. Individual

digits may be addressed and updated without re-

writing the entire display.

display brightness

■ Single external resistor for output current

setting

■ Inputs with Schmitt trigger give superior noise

immunity

■ A single LED digit output (DIG1_LED) can be

used to drive up to 8 discrete LEDs

■ 8-step dimming circuit to control brightness of

individual LEDs for LED digit

■ 5.0V ( 10%) for V

■ Drives common-anode LED digits

■ Built-in power on reset and soft-start circuits

■ Available in SO24 package

Additionally it includes key scanning for an 8x2

key matrix which automatically scans a matrix of

up to 16 switches. STLED316S supports numeric-

type displays and reduces the overall BOM costs

through high integration. Also it provides ESD

protection of greater than 2kV HBM.

■ -40°C to 85°C operating temperature range

Applications

■ Set Top Boxes

■ White goods

The LED controller/driver is ideal as a peripheral

device to interface the display with a singlechip

microcomputer.

■ Home appliances

■ DVD players, VCRs
