Renesas SLG46620V-SKT

Overview

SLG46620V-SKT from Renesas Electronics is a one-time-programmable (OTP) GreenPAK mixed-signal matrix IC featuring 25 LUTs (8×2-bit, 16×3-bit, 1×4-bit), six analog comparators, an 8-bit SAR ADC with 3-bit PGA, two DACs, and dual internal voltage references. It operates from 1.8 V to 5.0 V across –40°C to +85°C and supports programmable delays, counters, DFFs, and three internal oscillators (LF, RC 25 kHz/2 MHz, ring). It serves as a configurable logic-and-analog subsystem in power management sequencing and sensor interface circuits.

For engineers reviewing the SLG46620V-SKT datasheet, SLG46620V-SKT pinout, SLG46620V-SKT application, or SLG46620V-SKT equivalent, this device enables rapid prototyping of custom mixed-signal functions without ASIC development-ideal for low-power embedded control, I/O expansion, and analog threshold detection where flexibility, small footprint (2×3 mm STQFN-20), and OTP configuration security are critical.

Technical Context

The SLG46620V-SKT implements a fully user-configurable interconnect matrix routing signals between 20 GPIO pins and 25 combinatorial LUTs, ten CNT/DLY macrocells (including wake-sleep control and FSM variants), twelve DFF/latches, two pipe delays, and six ACMPs with shared input multiplexing. Its architecture supports both digital logic synthesis and analog signal conditioning within a single die.

It integrates three independent oscillators (low-frequency, RC at 25 kHz or 2 MHz, ring), bandgap references, POR, and slave SPI for configuration readback and emulation. The NVM is OTP but supports on-chip emulation via GreenPAK Designer-allowing iterative design validation before final programming.

FAQ

What is the primary function of the SLG46620V-SKT?

The SLG46620V-SKT is a programmable mixed-signal matrix IC that combines digital logic (25 LUTs, counters, DFFs), analog functions (six ACMPs, 8-bit SAR ADC with 3-bit PGA, two DACs), and timing resources (three oscillators, programmable delays) into a single OTP-configurable device. It replaces discrete logic, comparators, and interface circuitry in compact embedded systems.

Does the SLG46620V-SKT support in-system reprogramming?

No-the SLG46620V-SKT uses one-time-programmable (OTP) NVM. However, Renesas GreenPAK Designer enables full on-chip emulation: users can configure, test, and debug logic and analog behavior dynamically while powered, without committing to OTP until design validation is complete. Once programmed, the SLG46620V-SKT retains its configuration permanently.

Can the SLG46620V-SKT operate from a 2.5 V supply?

Yes-the SLG46620V-SKT supports supply voltages from 1.8 V (±5%) to 5.0 V (±10%), which includes 2.5 V within specification. Electrical characteristics such as VIH/VIL thresholds, output drive strength, and ACMP input ranges are guaranteed across this full range, enabling interoperability with 2.5 V logic families without level translation.

How many analog comparators does the SLG46620V-SKT include, and how are their inputs routed?

The SLG46620V-SKT includes six analog comparators (ACMP0–ACMP5). Inputs are flexibly routed via shared GPIO pins: for example, Pin 6 accepts ACMP0(+) through ACMP4(+), Pin 7 supports ACMP0(–) through ACMP1(–) and PGA_OUT, and Pins 8–10, 12–15 provide additional differential and single-ended ACMP input paths-all configurable in GreenPAK Designer.

Is the SLG46620V-SKT pin-compatible with other GreenPAK devices?

No-SLG46620V-SKT has a unique 20-pin STQFN footprint and pin assignment optimized for its macrocell set and I/O routing. While other GreenPAK devices like SLG46621V share the same package outline, their pin functions differ significantly due to variations in internal resource allocation (e.g., ADC presence, comparator count, LUT topology), making direct PCB replacement impossible without redesign.
