[Arm-netbook] IC for analog and digital buttons (EOMA-68)

[Miguel Garcia]

We are designing a handheld-game console (based on EOMA-68).

The problem is that EOMA-68 has very few GPIO.

We have 17 digital buttons, 2 analog joystick (

) and 2 analog triggers (

).

Luke will use on the tablet the next IC: PCA9536.

However, this component does not meet our requirements.

Does anyone know a IC that meets these requirements (at least 17
digital buttons and at least 4 ADCs)?

Thanks.
