Product details
Overview
SLG46538V-SKT from Renesas Electronics is a programmable mixed-signal matrix IC with asynchronous state machine and dual-supply capability (VDD: 1.8–5 V, VDD2 ≤ VDD). It integrates four analog comparators, two voltage references, 19 macrocells (including LUTs, DFFs, counters, filters), I²C interface, crystal/RC oscillators, and 8-byte RAM + OTP memory. Used for voltage-level translation and mixed-signal logic in PC peripherals and portable electronics.
For engineers reviewing the SLG46538V-SKT datasheet, SLG46538V-SKT pinout, SLG46538V-SKT application, or SLG46538V-SKT equivalent, this page provides verified electrical specs, dual-domain I/O configuration details, macrocell resource mapping, I²C programmability support, and validated alternative options for GreenPAK-based system integration.
Technical Context
The SLG46538V-SKT implements a user-configurable interconnect matrix routing signals between 19 combination function macrocells, four ACMPs, two VREFs, and eight-state state machine logic. Its dual-supply architecture isolates IO0–IO8 (VDD domain) from IO9, IO10, IO12–IO17 (VDD2 domain), enabling bidirectional level translation without external components.
Programmability relies on one-time-programmable (OTP) NVM for final configuration, while on-chip emulation allows runtime reconfiguration during development via GreenPAK Designer. The device supports I²C serial communication (SCL/SDA on IO6/IO7), crystal oscillator (XTAL0/XTAL1), and three independent clock sources: 25 kHz/2 MHz configurable OSC, 25 MHz RC OSC, and external clock inputs (EXT_CLK0–EXT_CLK2).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Range | 1.8 V (±5 %) to 5 V (±10 %); supports direct interfacing with 1.8 V, 3.3 V, and 5 V logic domains. |
| VDD2 Range | 1.8 V (±5 %) to VDD; enables independent power domain for second I/O group with level-shifting capability. |
| Operating Temp | -40 °C to +85 °C; qualified for industrial and commercial embedded applications. |

| Memory | 8-byte RAM + OTP user memory; RAM accessible via I²C for runtime parameter storage and readback. |
Pinout & Package
SLG46538V-SKT is supplied in 20-pin STQFN package (2 mm × 3 mm × 0.55 mm, 0.4 mm pitch). Pin functions are defined per the STQFN-20 configuration; no MSTQFN-22 variant applies to this part number.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Main power supply | Supplies core logic, macrocells, and IO0–IO8; must be ≥ VDD2 and within 1.71–5.5 V range. |
| IO0 (Pin 2) | General-purpose input | Digital-only input without Schmitt trigger; used for low-noise signal sensing or clock gating control. |
| IO1 (Pin 3) | GPIO with OE* | Bidirectional I/O under user-controlled OE signal; supports push-pull (1x/2x) or open-drain NMOS output. |
| IO6 (Pin 8) | I²C clock (SCL) | Open-drain NMOS only; requires external pull-up; compatible with standard I²C bus timing. |
| IO7 (Pin 9) | I²C data (SDA) | Open-drain NMOS only; shares same electrical behavior as SCL; supports multi-master arbitration. |
| GND (Pin 11) | Ground reference | Common return path for VDD-side circuitry (IO0–IO8); separate from VDD2-side ground current paths. |
| VDD2 (Pin 14) | Secondary power supply | Powers IO9, IO10, IO12–IO17; enables level translation between VDD and VDD2 domains via internal logic. |
| IO13 (Pin 16) | Crystal oscillator input (XTAL0) | Analog input for external crystal; paired with IO14 (XTAL1); supports fundamental-mode crystals up to 25 MHz. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-supply I/O partitioning | IO0–IO8 powered by VDD; IO9, IO10, IO12–IO17 powered by VDD2 - enables hardware-level voltage domain bridging without external translators. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SLG46537V | 17 macrocells (vs. 19), no crystal oscillator, single-supply only (VDD only), no VDD2 pin. | Lacks dual-domain I/O and crystal timing; suitable only for simpler, single-voltage-domain logic tasks. | Select when cost sensitivity outweighs need for level translation or precision clocking. |
| SLG46620V | 24 macrocells, integrated 10-bit ADC, no ACMPs, supports higher VDD (up to 5.5 V), adds SPI interface. | Replaces analog comparators with ADC; better for digitization-heavy roles but loses fast comparator response (<100 ns). | Choose when analog signal digitization dominates over fast threshold detection and state-driven logic. |

FAQ
What is the primary function of the SLG46538V-SKT in a system design?
The SLG46538V-SKT serves as a field-programmable mixed-signal matrix IC that replaces discrete logic gates, comparators, timers, and level shifters. Its core function is to implement custom digital and analog signal conditioning, voltage domain bridging, and state-driven control - all within a single 2×3 mm STQFN package. The SLG46538V-SKT enables rapid iteration through GreenPAK Designer software before final OTP programming.
Can the SLG46538V-SKT operate with different supply voltages on VDD and VDD2 simultaneously?
Yes, the SLG46538V-SKT supports independent operation of VDD (1.8–5 V) and VDD2 (1.8 V to VDD), enabling true dual-voltage-domain I/O. Pins IO0–IO8 are referenced to VDD; IO9, IO10, IO12–IO17 are referenced to VDD2. This allows the SLG46538V-SKT to perform bidirectional level translation - for example, interfacing a 3.3 V microcontroller (VDD) with a 1.8 V sensor (VDD2) - without external components.
Does the SLG46538V-SKT support in-system programming after soldering?
No - the SLG46538V-SKT uses one-time-programmable (OTP) NVM for final configuration. However, it supports full on-chip emulation: users can load and test configurations via I²C without programming OTP, retaining full functionality while powered. Once verified, the SLG46538V-SKT configuration is written to OTP using GreenPAK Development Tools. Post-solder programming is possible only if the board provides I²C access and power during programming.
How many analog comparators does the SLG46538V-SKT include, and what are their key specifications?
The SLG46538V-SKT integrates four high-precision analog comparators (ACMP0–ACMP3). Each supports rail-to-rail input ranges (0 V to VDD for positive inputs; 0 V to 1.2 V for negative inputs), programmable hysteresis, and flexible pin assignment - e.g., IO4/IO5 serve as ACMP0±, IO8/IO12 as ACMP1±/ACMP3±. Input leakage is ≤1000 nA, and propagation delay is typically <200 ns, making the SLG46538V-SKT suitable for fast threshold detection in power monitoring and sensor interfaces.
Is crystal oscillator support available on the SLG46538V-SKT, and how is it implemented?
Yes, the SLG46538V-SKT includes dedicated crystal oscillator circuitry with XTAL0 (IO13) and XTAL1 (IO14) pins supporting fundamental-mode crystals up to 25 MHz. The crystal oscillator operates independently from the internal RC and configurable oscillators, providing high-accuracy timing for state machine execution, counter synchronization, and I²C baud rate generation. No external load capacitors are required - matching capacitance is integrated internally.
