Renesas SLG46120V

Overview

SLG46120V from Renesas Electronics is a one-time-programmable (OTP) GreenPAK mixed-signal programmable array with two analog comparators, five LUTs (one 2-bit + four 3-bit), twelve combination function macrocells, dual counter/delay generators (8-bit and 14-bit), RC oscillator (25 kHz / 2 MHz), and voltage reference. It operates from 1.8 V to 5.0 V and supports -40 °C to +85 °C ambient, enabling compact power sequencing and signal conditioning in space-constrained PC peripherals.

For engineers reviewing the SLG46120V datasheet, SLG46120V pinout, SLG46120V application, or SLG46120V equivalent, this device serves as a configurable logic and analog building block for custom timing, level-shifting, glitch filtering, and comparator-based control - especially where low quiescent current (<1 µA at 1.8 V), small STQFN-12 packaging, and rapid prototyping via GreenPAK Designer are required.

Technical Context

The SLG46120V implements a user-configurable interconnect matrix routing signals between 10 multi-function I/O pins and internal macrocells including analog comparators with selectable hysteresis (0/25/50/200 mV) and gain (1x/0.5x/0.33x/0.25x), programmable delay/deglitch filters, and pipe delay (8-stage, dual output). Its OTP NVM stores configuration permanently after programming.

Each GPIO supports multiple modes: digital input (with/without Schmitt trigger), push-pull or open-drain output (1X/2X drive strength), analog input for comparators, or Vref output. Pins 6 and 10 support 3-state operation via OE control, and all I/O pins offer selectable 10 kΩ/100 kΩ/1 MΩ pull-up/down resistors - except Pin 2, which is input-only with fixed pull-down.

Key Specifications

Pinout & Package

SLG46120V uses a 12-pin STQFN package (1.6 × 1.6 × 0.55 mm, 0.4 mm pitch) with exposed thermal pad. Power and ground are assigned to Pins 1 (VDD) and 7 (GND); Pin 2 is GPI-only; Pins 6 and 10 support 3-state outputs via OE control; Pin 12 accepts external clock input.

FAQ

What is the difference between SLG46120V and SLG46120P?

The SLG46120V and SLG46120P are functionally identical GreenPAK devices differing only in package dimensions: SLG46120V uses a 1.6 × 1.6 mm STQFN-12 (0.4 mm pitch), while SLG46120P uses a 2 × 2 mm STQFN-12 (0.5 mm pitch). Both share identical macrocell resources, electrical specs, and OTP configuration. SLG46120V targets ultra-dense layouts where board space is critical.

Can SLG46120V be reprogrammed after initial OTP programming?

No - SLG46120V contains one-time-programmable (OTP) NVM. Once programmed, the configuration is permanent and cannot be erased or rewritten. However, GreenPAK Designer supports on-chip emulation (non-volatile configuration retained only while powered), allowing full functional validation before committing to OTP programming.

Does SLG46120V support I²C or SPI communication interfaces?

No - SLG46120V does not include dedicated serial communication peripherals. It is a programmable logic and analog array; communication with host systems must be implemented externally using its GPIOs configured as bit-banged I²C/SPI signals or interfaced via MCU-controlled control lines.

What is the maximum operating frequency of the internal RC oscillator in SLG46120V?

The internal RC oscillator in SLG46120V supports two base frequencies: 25 kHz and 2 MHz. With optional pre-divider (×1/2/4/8) and secondary divider (×1/2/3/4/8/12/24/64), the lowest achievable output is ~390 Hz and the highest is 2 MHz - no higher-frequency modes are supported. The 2 MHz mode exhibits ±10 % accuracy across voltage and temperature.

How many GPIO pins on SLG46120V support analog comparator inputs?

Three GPIO pins on SLG46120V support analog comparator inputs: Pin 3 (ACMP0+), Pin 4 (ACMP0−), and Pin 6 (ACMP1+ with OE). These pins retain full digital I/O functionality when comparators are unused, and each comparator offers independent hysteresis and gain configuration via register settings.
