Renesas SLG46116V

Overview

SLG46116V from Renesas Electronics is a programmable mixed-signal matrix IC integrating two analog comparators, four combinational LUTs (two 2-bit, two 3-bit), three 8-bit counter/delay generators, a trimmed RC oscillator (25 kHz / 2 MHz), Power-On Reset, and a soft-start P-FET power switch with 1.25 A capability at 3.3 V VIN and 28.5 mΩ R_DS(ON) at 5.5 V. It serves as a configurable system-level power and signal control hub in space-constrained embedded applications.

For engineers reviewing the SLG46116V datasheet, SLG46116V pinout, SLG46116V application, or SLG46116V equivalent, this device supports rapid prototyping of power sequencing, LED/haptic drive logic, and system RESET with integrated analog sensing - all within a single 1.6 × 2.5 mm STQFN-14 package and OTP-programmable NVM configuration.

Technical Context

The SLG46116V implements a user-configurable digital interconnect matrix routing signals between macrocells including LUTs, DFFs, counters, and analog comparators. Its dual-mode GPIO pins support Schmitt-triggered or low-voltage digital I/O, analog comparator inputs (Pins 2 & 3), and programmable pull-up/down resistors (10 kΩ/100 kΩ/1 MΩ).

The integrated P-FET power switch features slew-rate-controlled turn-on with T_{Total_On} = 114–399 µs (depending on VIN), T_Rise = 92–296 µs, and precise threshold control via PWR_SW_ON pin (VIH = 0.85×VIN, VIL ≤ 0.3 V). The device operates across 1.5–5.5 V VIN and 1.71–5.5 V VDD, with quiescent current as low as 0.5 µA at 1.8 V.

Key Specifications

Pinout & Package

FAQ

What is the maximum continuous current the SLG46116V P-FET can deliver?

The SLG46116V P-FET delivers 1.25 A at VIN = 3.3 V and 25 °C ambient, with derating to 1.0 A at VIN = 1.5 V. Peak current capability is 1.5 A for ≤1 ms at 1% duty cycle. Actual sustained current depends on PCB thermal design and ambient temperature - refer to RDSON vs. temperature curves and SOA plots in the datasheet for safe operating limits.

Can the SLG46116V be reprogrammed after initial configuration?

No - the SLG46116V uses one-time-programmable (OTP) non-volatile memory. Configuration is permanently written during programming. However, Renesas GreenPAK Designer supports on-chip emulation: the device retains the configured logic as long as powered, enabling iterative testing without committing to OTP until final validation.

Does the SLG46116V support I²C or SPI communication?

No - the SLG46116V lacks serial communication interfaces. It is configured exclusively via Renesas' GreenPAK Programmer hardware and GreenPAK Designer software using the device's dedicated programming pins. Runtime host interaction is limited to GPIO signaling and analog comparator outputs.

How many independent timing functions can the SLG46116V implement simultaneously?

The SLG46116V supports three independent 8-bit counter/delay generators (CNT0–CNT2), plus a programmable delay macrocell with edge detection, pipe delay (8-stage), and RC oscillator with dual-stage division. This enables concurrent implementation of up to five distinct timing sequences - e.g., power-up delay, debounce filter, PWM period, watchdog timeout, and clock gating window.

What is the purpose of the separate AGND and GND pins on the SLG46116V?

AGND (Pin 8) and GND (Pin 9) provide isolated return paths for analog and digital circuitry respectively. AGND services the analog comparators and voltage reference to minimize noise coupling; GND handles digital I/O and macrocell switching currents. Proper separation maintains comparator accuracy and prevents digital switching transients from corrupting analog measurements.
