Renesas SLG46826G

Overview

SLG46826G from Renesas Electronics is a programmable mixed-signal matrix IC with in-system programmability, integrating dual-rail analog comparators (2× high-speed + 2× low-power), 2.048 kHz/2.048 MHz/25 MHz oscillators, analog temperature sensor, and 2-kbit I²C-compatible EEPROM emulation. It operates across 2.5–5 V (VDD) and 1.8–5 V (VDD2 ≤ VDD) supply domains and targets power-constrained portable electronics requiring configurable logic and analog functions.

For engineers reviewing the SLG46826G datasheet, SLG46826G pinout, SLG46826G application, or SLG46826G equivalent, this device supports rapid prototyping of custom signal conditioning, power sequencing, and wake/sleep control without ASIC development - especially where dual-voltage domain interfacing, low-quiescent-current analog monitoring, and field-updatable logic are required.

Technical Context

The SLG46826G implements a reconfigurable interconnect matrix linking 11 combination-function macrocells (including 2-/3-/4-bit LUTs, DFFs, ripple counters, and pipe delays) and 8 multi-function macrocells (each combining LUT + 8- or 16-bit counter/delay). Its analog subsystem includes four rail-to-rail comparators with independent reference selection and deglitch/edge-detection modes.

Dual-supply operation enables independent VDD (2.5–5 V) and VDD2 (1.8–5 V) domains for level-shifting between logic families. The embedded 2-kbit I²C EEPROM emulates non-volatile storage with software write protection, while Power-On Reset and three internal oscillators provide autonomous startup and timing without external components.

FAQ

What is the primary function of the SLG46826G in a system design?

The SLG46826G serves as a programmable mixed-signal matrix IC that replaces multiple discrete analog comparators, logic gates, timers, and voltage references with a single configurable device. Its role includes power sequencing, sensor signal conditioning, wake/sleep control, and I²C-based configuration storage - all implemented via user-defined interconnect and macrocell programming. The SLG46826G enables rapid customization without mask changes or new silicon spins.

Does the SLG46826G support true dual-supply operation with independent voltage domains?

Yes, the SLG46826G supports true dual-supply operation: VDD (2.5–5 V) powers the core logic and high-speed analog blocks, while VDD2 (1.8–5 V, VDD2 ≤ VDD) independently supplies selected I/O banks. This allows level translation between 1.8 V controllers and 3.3/5 V peripherals without external translators. Pin assignments and drive strength are configurable per bank, and I²C interface can operate from either supply domain.

How many times can the SLG46826G be programmed, and what memory technology is used?

The SLG46826G uses multiple-time programmable (MTP) non-volatile memory based on floating-gate technology, rated for ≥100 program/erase cycles. Configuration data - including macrocell settings, interconnect routing, and I²C EEPROM emulation contents - is stored in this NVM and retained for ≥20 years at +85 °C. Programming occurs in-system via I²C at standard speeds (up to 400 kHz), with no external programmer required.

What are the key timing resources integrated into the SLG46826G?

The SLG46826G integrates three independent internal oscillators: 2.048 kHz (for RTC and low-power timing), 2.048 MHz (for digital logic clocks), and 25 MHz (for high-speed signal generation). It also provides programmable delay/counter macrocells with resolution down to 1 oscillator cycle and ranges up to 16 bits. These resources eliminate external timing components and support precise, deterministic event scheduling in autonomous operation.

Can the SLG46826G replace discrete comparators and voltage references in sensor interface circuits?

Yes, the SLG46826G integrates four rail-to-rail analog comparators (two high-speed, two low-power) and two programmable voltage reference outputs (e.g., 1.2 V, VDD/2, or bandgap-derived). These can be directly connected to thermistors, photodiodes, or battery monitors, with comparator outputs routed to logic macrocells for hysteresis, latching, or pulse generation - fully replacing discrete op-amp/comparator/reference solutions in compact sensor nodes.
