Product details
Overview
SLG46721V-SKT from Renesas Electronics is a one-time-programmable (OTP) mixed-signal array integrating four analog comparators, two voltage references, nine LUTs (two 2-bit + seven 3-bit), five counter/delay generators, and programmable RC oscillator. It operates from 1.8 V to 5.0 V across –40 °C to +85 °C and is packaged in a 20-pin STQFN (2 × 3 × 0.55 mm, 0.4 mm pitch). It serves as a configurable logic and analog signal conditioning block in power sequencing and interface bridging.
For engineers reviewing the SLG46721V-SKT datasheet, SLG46721V-SKT pinout, SLG46721V-SKT application, or SLG46721V-SKT equivalent, this device supports rapid prototyping of custom digital/analog functions without ASIC development-ideal for voltage monitoring, timing control, debounce logic, and I/O expansion in space-constrained embedded systems.
Technical Context
The SLG46721V-SKT implements a user-configurable interconnect matrix linking 18 multi-function GPIOs to macrocells including analog comparators with selectable hysteresis (0/25/50/200 mV), programmable delay blocks (125–500 ns @ 3.3 V), and pipe delay (16-stage, 3 outputs). Its OTP memory stores routing and configuration data, enabling fixed-function behavior post-programming.
It features dual-voltage reference outputs (VREF0/VREF1), deglitch filters, inverters, and flexible I/O drive modes-including push-pull (1X/2X), open-drain NMOS (1X/2X/4X/SuperDrive), and analog input capability on pins 6, 7, 10, 12–15. Power-on reset threshold is 1.353 V (typ), with startup time under 0.3 ms.

Equivalent & Alternatives
The following parts are listed as comparable options for similar programmable mixed-signal array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SLG46533V | Fewer macrocells (3 ACMP, 1 VREF, 5 LUTs); no pipe delay; 16-pin STQFN | Suitable for simpler logic functions but lacks dual VREF and advanced delay capabilities needed for precision timing. | Select when cost and footprint are prioritized over analog flexibility and delay resolution. |
| SLG46620V | Higher I/O count (24 pins); includes 32-bit counter; same 20-pin STQFN option available | Better suited for complex state machines and longer timing intervals, but consumes more current in active mode. | Choose when extended counter range and additional LUTs justify higher power budget and design complexity. |
Compared with SLG46721V-SKT, SLG46533V offers reduced functionality and smaller footprint for basic logic, while SLG46620V provides greater macrocell depth and timing resolution at higher static power-making SLG46721V-SKT the optimal balance of analog integration, delay precision, and low-power operation for mid-complexity mixed-signal tasks.

FAQ
What programming tools are required to configure the SLG46721V-SKT?
The SLG46721V-SKT is programmed using Renesas' GreenPAK Designer software and a compatible programming adapter (e.g., SLG4DVKHV). The design is compiled into a .gpx file, which is then used to program the device's one-time-programmable (OTP) memory. No external programmer hardware is needed beyond the official GreenPAK development kit. The SLG46721V-SKT itself does not support in-system reprogramming after initial OTP write.
Does the SLG46721V-SKT support analog input on all GPIO pins?
No, analog input capability is limited to specific pins: Pins 6, 7, 10, 12, 13, 14, and 15 can serve as analog comparator inputs; Pins 18 and 19 support analog reference output (VREF0/VREF1) and may be configured as analog inputs. Pin 2 is input-only but digital only. All other GPIOs operate in digital mode only. This selective analog routing ensures signal integrity and avoids crosstalk in mixed-signal designs using the SLG46721V-SKT.
Can the SLG46721V-SKT generate precise timing delays without an external clock?
Yes, the SLG46721V-SKT integrates an internal RC oscillator with selectable frequencies (25 kHz or 2 MHz) and programmable pre-dividers, enabling accurate delay generation (e.g., 125–500 ns @ 3.3 V) without external timing components. Its programmable delay macrocell uses this internal clock source, and timing estimator data (Section 5.8) confirms sub-microsecond resolution across all supported VDD levels-making the SLG46721V-SKT self-contained for timing-critical functions like pulse stretching or synchronization.
What are the maximum output drive capabilities of the SLG46721V-SKT GPIOs?
The SLG46721V-SKT supports multiple output drive configurations: push-pull (1X/2X), open-drain NMOS (1X/2X/4X), and open-drain SuperDrive (up to 40 mA sink current at 5 V). Per datasheet Section 5.2–5.4, the SuperDrive mode delivers 25.8 mA (typ) at VOL = 0.4 V with 5 V supply-sufficient to directly drive LEDs, small solenoids, or logic-level MOSFET gates. Drive strength is configured per-pin via register settings, allowing mixed-mode I/O on the same device.
Is the SLG46721V-SKT pin-compatible with other GreenPAK devices?
No, the SLG46721V-SKT is not pin-compatible with other GreenPAK families. Its 20-pin STQFN footprint and specific pin functions-including dual VREF outputs on Pins 18/19, GPI-only Pin 2, and dedicated programming pins (16–20 in programming mode)-are unique to the SLG46721 series. Migration to SLG46533V or SLG46620V requires PCB layout changes due to differing pin counts, assignments, and power rail segmentation. Always verify pin mapping against the respective datasheet before substitution.
