PCA9901 Product details

Description

The PCA9901 is a 20 mA current source for a single LED that allows stand-alone blinking of a predefined pattern to off-load the microcontroller and save battery power.

Features

1 wire interface to control the device.
Stand-alone blinking capability while training the sequence to blink.
Sequence includes up to 3 blinking elements.
12-bit (4096 steps) LED ON and OFF timings for each blinking element: ON timing is captured between 1 ms and 255 ms OFF timing is captured between 20 ms and 5.1 s.
1.8 V compliant one-wire logic interface.
Training Start, Training End, Run-Once, Run, Stop and Reset commands.
