18-GPIO, 4 ACMPs, 8-State ASM, I2C, 17 LUTs (max.), 7 CNT/DLY (max.), 8 DFF/LATCH (max.) and other Macrocells

The SLG46531 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 SLG46531. This highly versatile device allows a wide variety of mixed-signal functions to be designed within a very small, low power single integrated circuit.

Macrocells Overview

Four Analog Comparators (ACMP);

Two Voltage References (Vref);

Seventeen Combination Function Macrocells:

  • Three Selectable DFF/Latch or 2-bit LUTs;
  • One Selectable Continuous DFF/Latch or 3-bit LUT;
  • Four Selectable DFF/Latch or 3-bit LUTs;
  • One Selectable Pipe Delay or 3-bit LUT;
  • One Selectable Programmable Function Generator or 2-bit LUT;
  • Five 8-bit delays/counters or 3-bit LUTs;
  • Two 16-bit delays/counters or 4-bit LUTs;

Asynchronous State Machine:

  • Eight States;
  • Flexible input logic from state transitions;

Serial Communications:

  • I2C Protocol compliant;

Pipe Delay - 16 stage/3 output (Part of Combination Function Macrocell);

Programmable Delay;

Additional Logic Functions - 2 Deglitch Filters with Edge Detectors;

Two Oscillators (OSC):

  • Configurable 25 kHz/2 MHz;
  • 25MHz Ring Oscillator;

Crystal Oscillator;

Eight Byte RAM + OTP User Memory:

  • RAM Memory space that is readable and writeable via I2C;
  • User defined initial values transferred from OTP.
