The SLG46620V has nearly double the on-chip resources when compared to previous generation parts. This new device also includes new functions, such as a hardware reset pin and a DAC. The chip is available in a 2.0 x 3.0 x 0.55 mm 20-pin STQFN.

The SLG46620 is a user programmable device with One-Time-Programmable (OTP) memory elements that are able to construct combinatorial logic elements. Three of the I/O Pins provide a connection for the bit patterns into the OTP on board memory. A programming development kit (below) allows the user the ability to create initial devices. Once the design is finalised, the programming code is forwarded to Silego to integrate into a production process.

Like other devices in the GPAK family, development of SLG46620V projects takes advantage of the GPAK development hardware and simple GUI interface of GPAK Designer, allowing engineers to quickly and easily implement new designs and respond to changing design requirements.

Features include;

Read Back Protection (Read Lock)

1.8V (±5%) to 5V (±10%) Supply

Operating temperature range: -40°C to 85°C

General purpose I/O (GPIO)

Super drive output

8-bit successive approximation register analogue-to-digital converter (SAR ADC)

Digital-to-analogue converters (DAC)

Analog comparators (ACMP)

Trimmed voltage reference (VREF)

Combinatorial lookup tables (LUTs)

Combination function macrocells

Digital comparators/pulse width modulators (DCMPs /PWMs) with selectable deadband

Counters/delays (CNT/DLY)

D flip-flops/latches

Programmable delay with edge detection

Three internal oscillators; Low-frequency/ring/trimmed RC

Power-on-reset (POR)

Slave SPI

“With the SLG46620V GreenPAK4, we are giving our customers a powerful new device that adds higher precision analogue capabilities to designs with an already high level of integration,” Silego adds.
