Si1153 RevB parts (Si1153-AB00-GM, Si1153-AB09-GM, Si1153-AB9X-GM) are launched in September 2018.
Comparing to Si1153 RevA parts, the major change is in interrupt modes. Si1153 RevA parts only support interrupt on every sample and whenever the sample is larger than a set threshold, while Si1153 RevB parts support multiple interrupt modes listed below. The host can configure ADCPOSTx registers to set different interrupt modes.
Mode 1: Interrupt on every sample.
Mode 2. Interrupt whenever the sample is larger/smaller than a set threshold.
Mode 3. Interrupt whenever the sample enters/exits the set threshold window.
Si1153 RevB is pin compatible with Rev A and fully backwards compatible in terms of software programming. Existing customers can easily switch to RevB parts without any changes. New customers can make use of the new interrupt mode in certain applications to reduce power consumption.
The Si1133/5x Optical Sensor EXP board now has an example project running on EFM32PG12 MCU to demonstrate our latest Si1153 for proximity/ambient light sensing and Si1133 for UV sensing. The example project will require an EFM32™ Pearl Gecko PG12 Starter Kit(SLSTK3402A) to plug in the Si1133/5x Optical Sensor EXP board through the 20pin expansion header.
The source code of the example project is provided in the attachment.
We also have a nice video describing all the features included in the demo. Please make sure to check it out before getting started.
