Dialog releases first fruits of Silego acquisition

January 18, 2018 // By Peter Clarke
Dialog Semiconductor Ltd. has launched two mixed-signal GreenPak ICs that can be programmed in-system, the first results of its acquisition of Silego Corp.

The SLG46824 and the SLG46826 are CMICs have two and four low-voltage analog comparators plus a lot of additional mixed-signal and FPGA-style circuitry to allow a variety of mixed-signal functions to be designed within a single IC. These CMICs include in-system and multi-time programming of non-volatile memory so that modifications can be made late in design cycle, in-the-field or on the production line.

The chips include a 2.048kHz oscillator that consumes a few hundred nanoamps when active making it suitable for watchdog timer applications, or other designs that require a low-speed oscillator that is always running. The power-on reset block operates continuously, which guarantees that the device will initialize correctly for any power ramp, and consumes just 100 nA at a 3.3 V supply voltage level.

The devices are programmed via a I2C serial interface. 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 I 2C-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.
