Description

The SLG46621 provides a small, low power component for commonly used mixed-signal functions. The user creates their circuit design by programming the one time Non-Volatile Memory (NVM) to configure the interconnect logic, the I/O Pins and the macro cells of the SLG46621. This highly versatile device allows a wide variety of mixed-signal functions to be designed within a very small, low power single integrated circuit. The macro cells in the device include the following (please see Block Diagram below):

• Six Analog Comparators (ACMP);

• Voltage References (Vref) with Chopper stabilized amplifier;

• Twenty five combinatorial Look Up Tables (LUTs);

- Eight 2-bit LUTs;

- Sixteen 3-bit LUTs;

- One 4-bit LUT;

- One combination function macrocell;

• One selectable Pattern Generator (PGEN) or 4-bit LUT;

• Ten Counter / Delay generators (CNT/DLY);

- Four 14-bit Delay/Counters;

- Six 8-bit Delays/Counters;

• Two Pipe Delays – 16 stage/3 output (Part of combination function macrocell);

• Two Programmable Delays;

• Additional logic functions – 2 Inverters;

• RC Oscillator (RC OSC);

• Low Frequency Oscillator (LF OSC);

• Ring Oscillator (Ring OSC);
