Renesas SLG46620G

Overview

SLG46620G from Renesas Electronics is a programmable mixed-signal matrix IC with 20-pin TSSOP packaging, integrating an 8-bit SAR ADC, six analog comparators, two DACs, 25 LUTs (eight 2-bit, sixteen 3-bit, one 4-bit), ten counters/delays, twelve DFFs/latches, and three internal oscillators. It operates from 1.8 V to 5.0 V across –40°C to +85°C and serves as a configurable logic-and-analog subsystem in power management and sensor interface circuits.

For engineers reviewing the SLG46620G datasheet, SLG46620G pinout, SLG46620G application, or SLG46620G equivalent, this device supports rapid prototyping of custom mixed-signal functions-including voltage monitoring, PWM generation, wake-sleep control, and analog signal conditioning-without FPGA-level complexity or MCU firmware overhead.

Technical Context

The SLG46620G implements a non-volatile, one-time-programmable (OTP) configuration matrix that routes signals between 20 GPIO pins and macrocells including combinational LUTs, sequential elements (DFFs/latches), analog comparators with selectable hysteresis, and programmable delay generators with edge detection. Its dual-power-rail architecture isolates pins 2–10 from pins 12–20 for independent current handling.

It features three on-chip oscillators (LF, ring, RC at 25 kHz/2 MHz), a 3-bit PGA with single-ended input support, and dual voltage references (VrefO_0/VrefO_1). All macrocell timing-including LUT propagation delays (e.g., 4.18 ns falling at 5 V) and counter response widths (e.g., 9.55 ns falling-edge detect at 5 V)-is characterized across 1.8 V, 3.3 V, and 5.0 V supply conditions.

FAQ

What is the maximum operating voltage for SLG46620G?

The SLG46620G supports a supply voltage range of 1.8 V (±5%) to 5.0 V (±10%), with absolute maximum rating of 7 V on VDD. Operation above 5.5 V violates electrical specifications and may cause permanent damage. The device's IOH/IOL performance and internal oscillator accuracy are guaranteed only within the specified 5.0 V ±10% window.

Does SLG46620G support in-system reprogramming after OTP programming?

No, SLG46620G uses one-time-programmable (OTP) non-volatile memory. Once programmed, the configuration is permanent and cannot be erased or rewritten. However, Renesas GreenPAK Designer allows full on-chip emulation-retaining active configuration while powered-enabling unlimited design iterations before final OTP commit.

How many analog comparators does SLG46620G integrate, and what are their input configurations?

SLG46620G integrates six analog comparators (ACMP0–ACMP5). Inputs are flexibly routed from GPIO pins: ACMP0–ACMP3 share positive inputs on Pin 6 and negative inputs on Pin 7 or Pin 10; ACMP4 uses Pin 2 (GPI) and Pin 6; ACMP5 uses Pins 4 and 5. Each supports internal reference selection and hysteresis of 0 mV or 25 mV.

Can SLG46620G generate PWM signals with adjustable dead time?

Yes, SLG46620G supports PWM generation with programmable deadband through its three Digital Comparator/PWM (DCMP/PWM) macrocells. Dead time is configured per instance using dedicated delay cells and edge-triggered logic, enabling safe commutation control for half-bridge or H-bridge drivers without external timing components.

What is the typical startup time for SLG46620G after power-on?

The SLG46620G exhibits a typical startup time (TSU) of 1.4 ms from VDD crossing the power-on threshold (PONTHR ≈ 1.46 V), with min/max bounds of 0.526 ms to 5.148 ms at 1.8 V, 0.660 ms to 3.740 ms at 3.3 V, and 0.638 ms to 2.914 ms at 5.0 V. This ensures reliable initialization before host processor handoff.
