Mixed-signal programmable adds I2C interface, expands logic
Added to a family of configurable mixed-signal ICs (CMICs), the addition of I²C enables designers to read and change device configuration, such as analogue comparator thresholds, on-the-fly. The I²C block can also act as a digital IO expander. Included in the SLG46533V 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 functions, along with the configurable digital and analogue blocks seen in previous generations of GPAK, are all packed into a 2.0 x 3.0 mm 20-pin STQFN with 18-GPIO. Program the part with the GUI interface of GPAK Designer. Unique to this latest generation, designers now have the ability to perform on-board emulation, within their design, using I²C.
Target applications include, often in combination:
– GPIO expander
– power sequencing
– voltage monitoring
– LED control
– glue logic
– timing adjustments
– watchdog timer
