Panel interface for telephones
BU8317KV
The BU8317KV is a large-scale integrated circuit which enables a serial input / output interface between the key input
required for panel boards used in PHS systems, portable telephones, and telephone answering machines and LED and
LCD control functions. It reduces the number of wiring harnesses needed between the main board in the telephone and
the panel board, and takes some of the processing load off the main CPU.
Applications
PHS systems, portable telephones, telephone answering machines
Features
1) 7
2) 12-bit LED driver. (6 bits can also function as input
pins)
3) 4-column 32-segment LCD driver. (internal bias-gen-
erating resistor)
7 keypad matrix interface.
4) Standby mode.
5) VQFP80 package.
Absolute maximum ratings (unless otherwise noted, Ta = 25 C)
Recommended operating conditions (Ta = 25 C)
