BU8310AK / BU8311KS / BU8313K

The BU8310AK, BU8311KS, and BU8313K are large-scale integrated circuits for telephones, which enable a serial in-

put/output interface between the key input required for telephone panel boards and LED control functions. They reduce

the number of wiring harnesses needed between the main board in the telephone and the panel board, and take some

of the processing load off the main CPU.

FApplications

Telephones and cordless telephones

FFeatures

1) Keypad matrix interface

2) LED interface

Key input is output as 16-bit serial data.

Internal chattering prevention circuit built into the

key input circuit.

LED control commands input as 16-bit serial data.

Bits with a pattern generator and pattern register

can be assigned three independent flashing pat-

terns in addition to being lighted or off.

Power consumption can be reduced using RST

pin input.

LED on and off control can be initiated using ENA

pin input or by commands setting all LEDs valid or

invalid.
