Renesas SLG46826V

Overview

SLG46826V from Renesas Electronics is a programmable mixed-signal matrix IC featuring dual power domains (VDD: 2.5–5 V, VDD2: 1.8–5 V), two high-speed and two low-power rail-to-rail analog comparators, three on-chip oscillators (2.048 kHz, 2.048 MHz, 25 MHz), an analog temperature sensor, and 2-kbit I²C-compatible EEPROM emulation. It implements configurable logic via eleven combination function macrocells and eight multi-function macrocells, enabling custom signal conditioning, timing control, and system supervision in space-constrained portable electronics.

For engineers reviewing the SLG46826V datasheet, SLG46826V pinout, SLG46826V application, or SLG46826V equivalent, this device supports rapid prototyping of mixed-signal functions-including voltage monitoring, wake/sleep sequencing, edge-triggered delay, and I²C-based configuration-without custom ASIC development or discrete component count escalation.

Technical Context

The SLG46826V integrates a reconfigurable interconnect matrix linking analog comparators, voltage references, oscillators, and digital macrocells (LUTs, DFFs, counters, pattern generators). Its dual-supply IO structure enables level-shifting between independent voltage domains without external translators.

Logic functionality is implemented through eleven combination macrocells (each selectable as 2-bit/3-bit LUT or DFF/LATCH) and eight multi-function macrocells (each combining 3-bit/4-bit LUT with 8-bit/16-bit counter/delay), all programmable via multiple-time NVM with in-system I²C interface.

Key Specifications

Pinout & Package

SLG46826V is available in two RoHS-compliant packages: 20-pin STQFN (2 mm × 3 mm × 0.55 mm, 0.4 mm pitch) and 20-pin TSSOP (6.5 mm × 6.4 mm × 1.2 mm, 0.65 mm pitch). Pin functions are identical across both packages.

FAQ

What is the primary function of the SLG46826V in a system design?

The SLG46826V serves as a field-programmable mixed-signal matrix that replaces discrete comparators, timers, logic gates, and voltage supervisors. It integrates analog comparators, oscillators, voltage references, and configurable digital macrocells-all programmable via I²C-to implement custom signal conditioning, power sequencing, wake/sleep control, and sensor interface logic without custom silicon. Its dual-supply architecture allows seamless integration across voltage domains in modern portable electronics.

Does the SLG46826V support true in-system programming after soldering?

Yes, the SLG46826V supports full in-system programmability via its I²C interface. Engineers can reconfigure its NVM-including logic connections, macrocell types, oscillator selections, and comparator thresholds-while the device is powered and mounted on the PCB. This enables design validation, firmware updates, and field calibration without physical rework or device replacement. The SLG46826V retains configuration through power cycles and supports up to 100 program/erase cycles per memory location.

How does the dual power supply (VDD/VDD2) of the SLG46826V improve system design?

The SLG46826V's separate VDD and VDD2 supplies allow independent powering of analog/comparator blocks (VDD) and GPIO/I²C interface (VDD2). This enables direct interfacing with 1.8 V sensors or radios while maintaining 3.3 V or 5 V compatibility for host controllers-eliminating external level shifters. VDD2 must be ≤ VDD, and both rails operate over wide ranges (VDD: 2.5–5 V; VDD2: 1.8–5 V), enhancing flexibility in mixed-voltage portable systems where the SLG46826V is deployed.

Can the SLG46826V replace an external EEPROM in a design?

Yes, the SLG46826V includes 2-kbit (256 × 8) I²C-compatible emulated EEPROM with software write protection. It stores configuration data, calibration values, or device identifiers persistently and is accessed using standard I²C commands. Unlike discrete EEPROMs, it requires no additional footprint or routing-reducing BOM count and board area. Write endurance is rated at 100,000 cycles, and data retention exceeds 10 years at +85 °C, making it suitable for long-lifecycle SLG46826V-based products.

What timing precision does the SLG46826V achieve for programmable delays?

The SLG46826V achieves sub-microsecond timing precision for programmable delays using its dedicated macrocells and internal oscillators. With the 25 MHz oscillator, delay resolution is 40 ns; with the 2.048 MHz oscillator, it is ~488 ns; and with the 2.048 kHz oscillator, it reaches ~488 µs. Edge-triggered delay outputs are jitter-free and fully synchronous to the selected clock source, enabling reliable power rail sequencing, pulse stretching, and one-shot generation-critical for repeatable behavior in SLG46826V-based timing applications.
