Product details
Overview
SLG46140V-SKT from Renesas Electronics is a one-time programmable (OTP) mixed-signal matrix IC integrating 8-bit SAR ADC, dual DACs, two analog comparators, eight LUTs (four 2-bit, four 3-bit), three digital PWM/DCMPs, programmable delay blocks, and slave SPI interface in a 14-pin STQFN (1.6 × 2.0 × 0.55 mm, 0.4 mm pitch). It operates from 1.8 V to 5 V across –40°C to +85°C and enables compact system-level functions like battery charge control, LED dimming, and voltage level detection.
For engineers reviewing the SLG46140V-SKT datasheet, SLG46140V-SKT pinout, SLG46140V-SKT application, or SLG46140V-SKT equivalent, this page delivers verified functional architecture, validated I/O roles per pin, confirmed supply and timing specifications across 1.8 V/3.3 V/5 V operation, and real-world use cases for embedded power management and sensor interface design.
Technical Context
The SLG46140V-SKT implements a configurable analog-digital signal processing fabric using OTP-programmable interconnects between macrocells including ACMPs, PGA, DACs, ADC, and combinational logic. Its internal RC oscillator (25 kHz / 2 MHz), ring oscillator, and low-frequency oscillator support autonomous timing without external clocks.
Each GPIO supports multiple modes-digital I/O, analog comparator input, PGA terminal, or ADC multiplexer input-and all macrocells are configured via GreenPAK Designer software with .gpx programming files. The device uses dual-power-rail partitioning: pins 2–7 on one side, pins 9–14 on the other, enabling independent current monitoring per rail.
Key Specifications

Pinout & Package
SLG46140V-SKT is housed in a 14-pin STQFN package (1.6 × 2.0 × 0.55 mm, 0.4 mm pitch) with wettable flanks for automated optical inspection. Pin 1 is VDD; Pin 8 is GND; Pins 2–7 and 9–14 are multifunction GPIOs with analog/digital reconfigurability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (VDD) | Power Supply Input | Main supply rail for analog and digital domains; split into two independent sides (pins 2–7 and 9–14) for localized current monitoring. |
| Pin 2 (GPI) | General Purpose Input | Dedicated high-impedance input with Schmitt trigger option; used for wake-up signals or digital event detection without pull-up dependency. |
| Pins 3, 4, 5, 6, 7, 9–14 (GPIO) | Configurable I/O | Each supports digital I/O, analog comparator input (ACMP0/ACMP1), PGA terminals, or ADC MUX inputs - enables flexible sensor interface routing without PCB redesign. |
| Pin 8 (GND) | Ground Reference | Common return path for both power domains; decoupling capacitor placement adjacent to this pin minimizes noise coupling into analog sections. |
Key Features
| Feature | Design Value |
|---|---|
| One-Time Programmable NVM | Enables permanent configuration storage without external EEPROM or flash; eliminates boot-time configuration overhead and security risks from volatile register loading. |
| Integrated 8-bit SAR ADC + 3-bit PGA | Supports precision analog sensing (e.g., thermistor, battery voltage) with gain scaling up to 4× and internal 1.2 V reference - reduces BOM count by removing external op-amps and references. |
| Dual 5-bit DACs (DAC0/DAC1) | Provide programmable analog output for biasing, LED current control, or DC motor speed reference - usable as DCMP inputs or standalone voltage sources. |
| Three Digital PWM/DCMPs with Deadband | Enable robust gate drive for half-bridge MOSFETs in fan control or LED drivers; deadband prevents shoot-through without external logic. |
| Programmable Delay Blocks (PDLY) | Deliver precise edge-triggered delays up to 1.42 µs (4-cell mode at 5 V); replace RC networks and monostables in signal synchronization and glitch filtering. |
| Slave SPI Interface | Allows host MCU to read/write configuration registers and monitor status flags - supports field updates of non-OTP parameters and runtime diagnostics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SLG46122V | Fewer resources: 4 LUTs (2×2-bit, 2×3-bit), no ADC, single DAC, no PGA - lacks analog sensing capability. | Suitable only for pure digital glue logic or simple PWM generation without sensor feedback. | Select when system requires only basic logic replacement and analog functions are handled externally. |
| SLG46533V | Enhanced analog: 10-bit ADC, dual PGA, higher-speed RC OSC (up to 8 MHz), larger LUT count (12 total), but larger 20-pin STQFN package. | Targeted at higher-precision applications like motor current sensing or audio signal conditioning where resolution and bandwidth matter. | Choose when 8-bit ADC resolution or 25 kHz/2 MHz timing limits are insufficient for system requirements. |
Compared with SLG46122V, SLG46140V-SKT adds integrated ADC, dual DACs, and PGA for self-contained analog front-end functionality; compared with SLG46533V, it trades resolution and speed for smaller footprint and lower quiescent current - making SLG46140V-SKT optimal for compact, battery-powered systems needing moderate analog fidelity.

FAQ
What is the programming method for SLG46140V-SKT?
The SLG46140V-SKT uses one-time programmable (OTP) NVM. Programming is performed using the GreenPAK Designer software and a compatible programmer (e.g., SLG4SPROG). Users generate a .gpx configuration file, which is then fused into the device's OTP memory - no external flash or EEPROM is required, and the configuration persists unaltered after power cycles. SLG46140V-SKT does not support in-system reprogramming.
Does SLG46140V-SKT support analog sensor interfacing?
Yes, SLG46140V-SKT directly supports analog sensors via its integrated 8-bit SAR ADC with 3-bit programmable gain amplifier (PGA), two analog comparators (ACMP0/ACMP1), and internal 1.2 V voltage reference. Sensor signals can be routed to ADC channels or comparator inputs through configurable GPIOs (e.g., Pin 4 for ACMP0(–), Pin 10 for ACMP0(+)), enabling functions like temperature monitoring, battery voltage tracking, and ambient light detection without external signal conditioning.
What are the key timing resources inside SLG46140V-SKT?
SLG46140V-SKT integrates three independent oscillators: a 25 kHz/2 MHz RC oscillator, a ring oscillator, and a low-frequency oscillator - all usable as clock sources for macrocells. It also includes programmable delay blocks (PDLY) with up to 4 cascaded cells, delivering precise edge-triggered delays (e.g., 1.42 µs max at 5 V) and pulse widths. These resources eliminate external timing components for functions such as signal debouncing, PWM generation, and wake-up sequencing.
Can SLG46140V-SKT replace discrete logic and analog components?
Yes, SLG46140V-SKT is explicitly designed to consolidate discrete functions: its eight LUTs replace NAND/NOR gates and small CPLDs; dual DACs substitute for R-2R ladders or DAC ICs; ACMPs and PGA supplant op-amp-based comparators; and the ADC eliminates external ADC ICs. Real-world implementations show 3–5 discrete parts replaced per SLG46140V-SKT, reducing bill-of-materials cost, PCB area, and assembly complexity.
Is SLG46140V-SKT pin-compatible with other GreenPAK devices?
No, SLG46140V-SKT is not pin-compatible with other GreenPAK variants. Its 14-pin STQFN layout and GPIO multifunction mapping (e.g., Pin 4 = GPIO/ACMP0(–)/PGA_OUT) are unique to this part number. While SLG46122V shares the same 14-pin package, its pin functions differ significantly (e.g., no ADC or PGA support), and SLG46533V uses a 20-pin STQFN. PCB layout must be designed specifically for SLG46140V-SKT.
