Dialog introduces first configurable mixed-signal IC with in-system programming

Dialog’s latest CMIC products feature in-system programming and reprogrammable functionality, simplifying design modifications at the end of the design cycle, in the field or on the production line

Dialog Semiconductor has launched the Configurable Mixed-Signal IC (CMIC) GreenPAK™ SLG46824 and SLG46826. This is the first new CMIC product launched following Dialog's acquisition of Silego Technology, the creator and market leader of CMIC technology.

The SLG46826 and SLG46824 are the first CMICs on the market to support in-system programming using a simple I ² C serial interface. This simplifies the development process and makes system design easy by allowing an unprogrammed GreenPAK chip to be mounted on the PCB and the non-volatile memory (NVM) to be programmed in-system. This flexibility also facilitates production, as the configuration of the device can be easily modified or features can be added by programming the non-volatile memory on the production line. The NVM on the device supports 1,000 erase/write cycles. In addition, the SLG46826 includes 2 kbits of EEPROM emulation memory, which can replace an I ² C -compatible serial EEPROM on the customer's board, supporting the storage of backup configuration data, checksums, and a serial number.

Both CMICs are available in a 2.0 x 3.0 mm 20-pin STQFN package and feature low-power analog and digital resources such as analog comparators (ACMPs), internal reference voltages, power-on resets, and more advanced digital resources such as multi-function macrocells. Using an internal low-power reference voltage to run the low-power analog comparator, typical power consumption is only 2.5 μA for two ACMPs that continuously monitor external signals. In addition, the 2.048 kHz oscillator consumes only a few hundred nanoamps of current when running, making it ideal for watchdog timer applications or other designs that require a low-speed oscillator and always run. The power-on reset module is always running, ensuring that the device can be properly initialized at any power-up speed, and it consumes only 100 nA of current at a 3.3 V supply voltage. These devices also have dual-supply capability, providing additional advantages for converting signals between two voltages.

“These two chips are our first GreenPAK devices that can be programmed in-system,” said John Teegen, Vice President and General Manager of Dialog Semiconductor’s Configurable Mixed Signal Business Unit. “The flexibility of in-system programming and the ability to program multiple times make them excellent new additions to the GPAK product family. Their advanced functionality and ultra-low power consumption will bring significant value to a wide range of battery-powered applications and expand the range of applications that can be supported.”
