The first configurable mixed-signal integrated circuity (CMICs) from Dialog Semiconductor, following its acquisition of CMIC pioneer Silego Technology, have just been announced.
According to the company, the SLG46826 and the SLG46824 are the market’s first CMICs that support in-system programming using a simple I2C serial interface. This capability is designed to streamline the development process and system checkout by allowing installation of an unprogrammed GreenPAK on the PCB, and supporting programming of the Non-Volatile Memory (NVM) in-system. This flexibility also has applications for late-stage modifications within a production environment.
The NVM on the 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), internal voltage reference, power-on reset and multi-function macro-cells. Running the low-power analog comparators with the internal low-power voltage reference consumes just 2.5 microamperes. In addition, the 2.048 kHz oscillator consumes a few hundred nanoamperes when active, making it suited for designs that require an always running low-speed oscillator, such as watchdog timer applications.
Because the power-on reset block operates all the time, the device will initialize correctly for any power ramp, and consumes just 100 nanoamperes at a 3.3 V supply voltage level. These devices are also dual supply capable, allowing signals to be translated between two voltage domains.
Target applications include:
- IoT Devices, Wearables, Smart Tags
- Smartphones, Tablets, Notebooks
- PCs and PC peripherals
- Headphones, Headsets
- Smart Building, Smart TV, Set Top Box
Commercial and Industrial Electronics
- Embedded computing
- Medical devices
