Programmable Mixed-signal IC adds Asynchronous State Machine

Silego Technology announces a new addition to the fifth generation of GreenPAK™ (GPAK) Programmable Mixed-signal ICs. The SLG46532V GPAK 5 further expands Silego's platform of Configurable Mixed-signal ICs (CMICs). Available in a 2.0 x 3.0 mm 20-pin STQFN with 17-GPIO, the SLG46532V comes with a host of features including an asynchronous state machine, I2C, dual supply, and a variety of programmable analog and digital blocks. Target applications include tablets, smartphones, notebooks, PCs and PC peripherals, wearables, servers, embedded PCs, data communications equipment, and so on.

Within the SLG46532V, the new Asynchronous State Machine can implement up to eight unique states with zero code, zero static power, and fail-safe operation. Because the device is dual supply, designers can create robust, state-dependent circuits interfacing two different voltage domains. The I2C block 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, giving this device the ability to expand two pins on a master device to as many as eight outputs or fifteen inputs across two voltage domains. Included in the SLG46532V are improved Counter/Delay blocks, featuring one-shot and frequency detect modes, as well as the capability to drive an external crystal, for precision timing.

Like other devices in the GPAK family, development of SLG46532V 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.

“With the SLG46532V we’ve taken our newest generation GreenPAK and added a whole new level of flexibility,” stated Sean Carty, Senior Product Marketing Engineer. “Dual supply capable GreenPAKs are a great way for Silego to offer our customers new solutions to interface two voltage domains.”
