Zero Code, Zero Static Power State Machine in Next-gen GreenPAK™

Aug. 15, 2017

Santa Clara, CA – January 6, 2016 – Silego Technology announces the fifth generation of GreenPAKTM (GPAK) Programmable Mixed-signal ICs. The SLG46531V GPAK 5 further expands Silego’s industry leading platform of Configurable Mixed-signal ICs (CMICs).

This latest generation device, including Silego’s new Asynchronous State Machine and I2C blocks, introduces even more flexibility, functionality, and ease of design to the NVM programmable GPAK family of devices. With the addition of the Asynchronous State Machine, designers can implement up to 8 unique states with zero code, zero static power, and fail-safe operation. The addition of I2C enables designers to change device configuration, such as analog comparator thresholds, on-the-fly. The I2C block can also act as a digital IO expander. Included in the SLG46531V are improved Counter/Delay blocks, featuring one-shot and frequency detect modes, as well as the capability to drive an external crystal oscillator.

These new functionalities, along with the configurable digital and analog blocks seen in previous generations of GPAK, are all packed into a tiny 2.0 x 3.0 mm 20-pin STQFN with 18-GPIO.

Like other devices in the GPAK family, development of SLG46531V projects takes advantage of the easy-to-use GPAK development hardware and simple GUI interface of GPAK Designer, allowing engineers to quickly and easily implement new designs and respond to changing design requirements. Unique to this latest generation, designers now have the ability to perform on-board emulation, within their design, using I2C.

“We have really taken a huge leap forward in terms of functionality and flexibility with GreenPAK 5,” states Sean Carty, Senior Product Marketing Engineer. “These devices offer our customers the potential to do even more with an already extremely versatile platform.”
