Renesas SLG46534V

Overview

SLG46534V from Renesas Electronics is a programmable mixed-signal matrix IC with asynchronous state machine, featuring three analog comparators, nineteen combination function macrocells (including LUTs, DFFs, counters/delays), I²C interface, and dual RC oscillators (25 kHz/2 MHz/25 MHz). It operates from 1.8 V to 5 V across –40 °C to +85 °C and is packaged in a 14-pin STQFN (2 × 2.2 × 0.55 mm, 0.4 mm pitch). It serves as a configurable logic and signal-conditioning solution in power management sequencing and system-level glue logic.

For engineers reviewing the SLG46534V datasheet, SLG46534V pinout, SLG46534V application, or SLG46534V equivalent, this page delivers verified electrical specs (I²C up to 400 kHz, ACMP offset ±10.9 mV, ASM output delay as low as 32 ns at 5 V), macrocell configuration details, real-world use cases in PC peripherals and handheld electronics, and validated alternative parts for design flexibility.

Technical Context

The SLG46534V implements a user-programmable interconnect matrix routing signals between 12 GPIOs, three ACMPs, two deglitch filters with edge detection, and an 8-state asynchronous state machine. Its macrocell architecture supports reconfigurable logic (2-/3-/4-bit LUTs), sequential elements (DFFs/latches), programmable delays (up to 1265 ns), and pattern generation - all configured via one-time-programmable (OTP) NVM.

It integrates dual RC oscillators (25 kHz, 2 MHz, and 25 MHz) with fast-start modes, crystal oscillator support, and flexible I²C slave operation on pins 6 (SCL/GPIO) and 7 (SDA/GPIO) using NMOS open-drain outputs. Power-on reset (PONTHR = 1.54 V typ.) and supply monitoring are built-in, with per-rail current limits (45 mA VDD side, 86 mA GND side).

FAQ

What is the maximum I²C clock frequency supported by the SLG46534V?

The SLG46534V supports I²C Fast-mode operation up to 400 kHz, compliant with standard I²C specifications. This is confirmed in Section 5.5 of the official datasheet, where tLOW ≥1300 ns and tHIGH ≥600 ns are specified under all valid VDD conditions (1.71–5.5 V). Pins 6 (SCL/GPIO) and 7 (SDA/GPIO) operate exclusively as NMOS open-drain outputs in I²C mode, requiring external pull-ups.

Does the SLG46534V include internal non-volatile memory, and how is it programmed?

Yes, the SLG46534V contains one-time-programmable (OTP) non-volatile memory used to store the user's configuration of interconnect routing, macrocell settings, and I/O definitions. Programming is performed using Renesas' GreenPAK Development Tools - first via on-chip emulation (volatile, powered-only), then final OTP programming for production. The SLG46534V does not support in-system reprogramming after OTP write.

Can the SLG46534V operate with a 25 MHz clock source, and what are its accuracy limitations?

Yes, the SLG46534V integrates a dedicated 25 MHz RC oscillator (OSC1), functional at VDD ≥2.5 V. Per Table 12 in the datasheet, its worst-case frequency error is –49.43 % to +4.88 % over full VDD (1.71–5.5 V) and temperature (–40 °C to +85 °C). This makes it suitable for non-critical high-speed timing (e.g., PWM generation, clock division) but not for precision timing like UART baud rate generation.

How many analog comparators does the SLG46534V have, and what input voltage ranges do they support?

The SLG46534V includes three independent analog comparators (ACMP0–ACMP2). Each supports a positive input range of 0 V to VDD and a negative input range of 0 V to 1.2 V, regardless of supply voltage (1.8 V, 3.3 V, or 5 V). This allows flexible use - for example, comparing a resistor-divider voltage against a fixed 1.2 V reference or monitoring VDD itself using internal bandgap.

What is the operating temperature range and supply voltage specification for the SLG46534V?

The SLG46534V is rated for industrial operation from –40 °C to +85 °C ambient temperature. Its supply voltage range is 1.8 V (±5 %) to 5 V (±10 %), meaning it functions reliably at 1.71–1.89 V, 2.97–3.63 V, and 4.5–5.5 V. Absolute maximum ratings allow transient exposure up to 7 V on VDD, but sustained operation outside the specified range may impair functionality or reliability.
