Renesas SLG46620V

Overview

SLG46620V from Renesas Electronics is a programmable mixed-signal matrix IC integrating 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, ten counters/delays, twelve DFFs/latches, and three internal oscillators (LF, RC 25 kHz/2 MHz, ring). It operates from 1.8 V to 5 V across –40°C to +85°C and targets power-constrained system-level glue logic in PC peripherals and handheld electronics.

For engineers reviewing the SLG46620V datasheet, SLG46620V pinout, SLG46620V application, or SLG46620V equivalent, this device serves as a field-programmable alternative to discrete logic + analog signal conditioning, supporting rapid prototyping via GreenPAK Designer and OTP configuration for production.

Technical Context

The SLG46620V implements a reconfigurable interconnect matrix routing signals between 20 GPIO pins and macrocells including combinatorial LUTs, sequential elements (DFFs, latches), analog blocks (ACMPs, PGA, ADC, DACs), and timing resources (CNT/DLY, pipe delays, programmable delays with edge detection). Its architecture supports both digital logic synthesis and mixed-signal signal chain design within a single die.

It features dual power rail partitioning (Pins 2–10 on one side; Pins 12–20 on the other), read-back protection (Read Lock), slave SPI interface for configuration, and startup behavior governed by PONTHR (1.462 V typ) and TSU (1.4 ms typ at 3.3 V). All macrocell delays are voltage- and temperature-dependent, with typical propagation delays ranging from 4.18 ns (4-bit LUT at 5 V) to 347.14 ns (PDLY0 2-cell falling edge detect at 1.8 V).

FAQ

What is the primary function of the SLG46620V in system design?

The SLG46620V serves as a field-programmable mixed-signal matrix that replaces discrete logic gates, comparators, timers, and analog front-end components. Its core function is to implement custom digital state machines and analog signal conditioning - such as sensor threshold detection, PWM generation, and ADC preprocessing - all within a single 20-pin STQFN package. This reduces board area, component count, and design iteration time compared to traditional discrete solutions.

Does the SLG46620V support in-system reprogramming after deployment?

No, the SLG46620V uses One-Time-Programmable (OTP) non-volatile memory for final configuration. However, during development, Renesas GreenPAK Designer allows full on-chip emulation without programming the NVM - meaning logic and analog configurations can be tested and modified repeatedly while powered. Once verified, the design is written to OTP memory, and SLG46620V retains that configuration permanently.

How many analog comparators does the SLG46620V include, and what input configurations do they support?

The SLG46620V integrates six analog comparators (ACMP0–ACMP5). Each supports single-ended, differential, and pseudo-differential input modes. Inputs are routed from dedicated GPIO pins (e.g., Pin 6 for ACMP0+/1+/2+/3+/4+, Pin 7 for ACMP0−/1−/PGA_OUT), with programmable hysteresis (0 mV or 25 mV) and low-bandwidth mode for noise immunity. The SLG46620V datasheet specifies ACMP input voltage ranges up to VDD on the positive input and up to 1.2 V on the negative input.

Can the SLG46620V operate from a 1.8 V supply while driving 3.3 V logic levels?

Yes, the SLG46620V supports 1.8 V ±5% supply operation and offers push-pull and open-drain GPIO configurations with selectable drive strength (1x/2x/4x). At 1.8 V, VOH is guaranteed ≥1.697 V (4x drive, IOH = 100 µA), which meets VIH requirements for many 3.3 V CMOS inputs. For robust interfacing, use open-drain outputs with external pull-ups to 3.3 V - a configuration explicitly supported by SLG46620V's GPIO architecture.

What oscillator options are available on the SLG46620V, and how are they selected?

The SLG46620V includes three internal oscillators: a low-frequency (LF) oscillator, a ring oscillator, and an RC oscillator configurable for 25 kHz or 2 MHz operation. Selection is performed entirely in the GreenPAK Designer software by assigning clock sources to macrocells (e.g., counters, ADC, LUTs). No external components are needed - all oscillators are factory-trimmed and require no external capacitors or crystals. Startup time from power-on is 1.4 ms typical at 3.3 V.
