Dialog Semiconductor introduces CMICs with In-System-Programming

April 10, 2018 Jamie Leland

Dialog Semiconductor has launched the GreenPAK SLG46824 and SLG46826, its first configurable mixed-signal ICs (CMICs), following the acquisition of Silego Technology.

The SLG46826 and the SLG46824 support in-system programming using an I2C serial interface. This allows the installation of an un-programmed GreenPAK on the PCB, and supports programming of the non-volatile memory (NVM) in-system, for easy system checkout. This flexibility is also beneficial in the production environment, as it is easy to modify the configuration or add functionality to these devices by programming the non-volatile memory on the production line. The NVM on this device is specified for 1,000 erase/write cycles. Additionally, the SLG46826 includes 2 kbits of EEPROM emulation memory that can replace an I2C-Compatible Serial EEPROM on the customer’s board, supporting storage of backup configuration data, a checksum, or a serial number.

Available in a 2.0 x 3.0 mm 20-pin STQFN package, both CMICs are equipped with low power consumption analog and digital resources like analog comparators (ACMPs), an internal voltage reference, power-on reset, and more advanced digital resources like multi-function macro-cells. Running the low power analog comparators with the internal low power voltage reference consumes just 2.5 µA typical for two ACMPs that are continuously monitoring external signals. In addition, the 2.048 kHz oscillator consumes a few hundred nanoamps when active, which makes it suited for watchdog timer applications, or other designs that require a low-speed oscillator that is always running. The power-on reset block operates all the time, which helps ensure that the device will initialize correctly for any power ramp, and consumes just 100 nA at a 3.3 V supply voltage level. These devices are also dual supply capable, offering a further benefit of being able to translate signals between two voltage domains.
