Providing lightening the burden of design and cost reduction by simple key-scan IC

October 20, 2009

New Japan Radio releases the NJU6010, 24-KEY (4-output and 6-input) key-scan IC

October 20, 2009 - New Japan Radio Co., Ltd. has introduced to the market the NJU6010, key-scan IC, suitable for car-audio and information panel that have a lot of key-switches.

[Background of development]

Recently, in car-audio and information panel, the increasing of LCD segment number and key-switch number, make wiring complicated. Therefore some problems rise as bellow.

[Features]

The NJU6010 consists of serial interface, oscillator, key-scan circuit, key-register and power on reset circuit.

1.Realizing the wiring reduce and the burden lightening of microprocessor
The NJU6010, a key-scan IC can control 24-key input data, housed in compact package SSOP16(5.0×6.4×1.25mm typ.). It can be mounted near the operation panel, so it realizes the wiring reduction. Furthermore, it realizes the burden reduction of microprocessor, by key-scan function.
2.Providing cost reduction by built-in oscillator
Built-in oscillation circuit for logic-circuit reduces external parts.
3.Wide operating temperature range
The NJU6010 has wide operating temperature range, -40°C to +105°C, requiring for Auto-motive use.
