Renesas SLG46536V-SKT

Overview

SLG46536V-SKT from Renesas Electronics is a programmable mixed-signal matrix IC featuring 14-pin STQFN (2 × 2.2 × 0.55 mm, 0.4 mm pitch), three analog comparators (ACMP0–ACMP2), I²C serial interface (up to 400 kHz), and 16×8 RAM with OTP-configurable NVM. It operates from 1.8 V ±5% to 5 V ±10% across –40 °C to +85 °C and supports configurable RC oscillators (25 kHz / 2 MHz / 25 MHz) for timing-critical embedded logic functions.

For engineers reviewing the SLG46536V-SKT datasheet, SLG46536V-SKT pinout, SLG46536V-SKT application, or SLG46536V-SKT equivalent, this device serves as a low-power, field-programmable alternative to discrete logic + analog signal conditioning in space-constrained PC peripherals, handheld electronics, and datacom power management subsystems.

Technical Context

The SLG46536V-SKT implements a reconfigurable interconnect matrix routing signals between 14 GPIO pins, three ACMPs, two deglitch filters with edge detection, and 26 combination-function macrocells-including LUTs (2-bit, 3-bit, 4-bit), DFFs, counters/delays (5× 8-bit, 2× 16-bit), and a programmable pattern generator. Its I²C interface enables runtime configuration and read-back protection via NVM lock.

Power management includes dual-side rail partitioning (Pins 2–8 vs. 10–14), POR with programmable thresholds (PONTHR = 1.41–1.66 V), and selectable oscillator startup modes (fast-start or auto-power). All macrocells support independent drive strength (1X/2X/4X NMOS OD, push-pull) and Schmitt-trigger inputs with adjustable hysteresis (25/50/200 mV).

FAQ

What is the primary function of the SLG46536V-SKT in an embedded system?

The SLG46536V-SKT serves as a programmable mixed-signal matrix IC that replaces discrete logic gates, analog comparators, RC timing networks, and basic state machines. It configures its internal interconnect, macrocells (LUTs, DFFs, counters), and three ACMPs via one-time-programmable NVM to implement custom signal conditioning, sequencing, and control logic - all within a 2.0 × 2.2 mm STQFN package. This makes SLG46536V-SKT ideal for compact, low-power embedded subsystems where board space and BOM count are critical.

Does the SLG46536V-SKT support I²C communication, and what are its timing limits?

Yes, the SLG46536V-SKT supports standard-mode I²C communication with SCL and SDA pins (Pins 6 and 7) operating as NMOS open-drain outputs. It complies with I²C specifications up to 400 kHz clock frequency, with minimum tLOW = 1300 ns, tHIGH = 600 ns, and tSU_DAT = 100 ns. The I²C interface enables host MCU configuration, register read-back, and status monitoring - and SLG46536V-SKT retains full functionality even when I²C is disabled in the NVM configuration.

Can the SLG46536V-SKT generate precise timing delays, and what is the resolution?

Yes, the SLG46536V-SKT includes five 8-bit and two 16-bit counter/delay macrocells, each capable of generating programmable delays with sub-microsecond resolution. At 5 V supply, typical delay resolution is 10–20 ns per step for short delays (e.g., 10–100 ns), scaling to ~225 ns per step for longer delays (e.g., 1 µs range). Measured delay accuracy is ±10% over temperature and voltage - sufficient for debouncing, pulse stretching, and synchronous logic timing in SLG46536V-SKT-based designs.

How many analog comparators does the SLG46536V-SKT include, and what input ranges do they support?

The SLG46536V-SKT integrates three independent analog comparators (ACMP0, ACMP1, ACMP2). Each accepts a positive input ranging from 0 to VDD and a negative input ranging from 0 to 1.2 V - enabling flexible configurations such as rail-to-rail sensing, fixed-reference comparison, or differential measurement with external resistive dividers. ACMP offset voltage is specified at ±10.9 mV over temperature, and built-in hysteresis options (25/50/200 mV) improve noise immunity in SLG46536V-SKT applications like power fault detection.

Is the SLG46536V-SKT pin-compatible with other GreenPAK devices, and can it be substituted directly?

No, the SLG46536V-SKT is not pin-compatible with other GreenPAK devices due to its unique 14-pin STQFN layout and specific pin assignments (e.g., Pin 2 = GPI only, Pins 6/7 = I²C-only open-drain). While SLG46537V shares the same pinout and macrocell structure, SLG46620V uses a 20-pin STQFN and different GPIO mapping. Substitution requires PCB redesign and NVM reconfiguration - SLG46536V-SKT must be selected based on its exact feature set, not assumed interchangeable.
