SLG46801 Übersicht
A GreenPAK (Green Programmable Analog Kit) device is a category of configurable mixed-signal IC that combines analog comparators, digital logic, lookup tables, oscillators, and counter/delay blocks in a single chip. Engineers use GreenPAK parts to replace dozens of discrete analog and logic components with one programmable device, reducing BOM count, PCB area, and power consumption. The SLG46801 sits within the power management and mixed-signal IC ecosystem as a glue-logic and analog front-end companion to a host MCU.
Key features include two high-speed analog comparators, configurable lookup tables (LUTs), two internal oscillators (10 kHz and 25 MHz), counters and delays, and multi-time programmable non-volatile memory that retains the user configuration through power cycles. The integrated I2C interface enables in-system reconfiguration, allowing field updates of the analog and logic behavior without hardware rework. The WLCSP option delivers the industry's smallest GreenPAK footprint, while the STQFN option supports conventional reflow and inspection processes.
The SLG46801 architecture pairs an analog macro-cell array with a digital routing fabric, so each analog comparator output, oscillator, or external pin can be connected to any LUT, counter, or I/O through the configuration bitstream. The MTP cell array stores the design permanently yet allows unlimited reprogramming during development and limited in-field updates, eliminating the external EEPROM used by older CPLD-style glue devices. This makes the SLG46801 a strong fit for always-on sensor interfaces, push-button and capacitive-touch decoding, battery management housekeeping, and reset sequencing in compact products.
Typical applications include smart-ring heart-rate and motion sensor signal conditioning, smartwatch user-interface glue logic, fitness-band battery and charging supervisors, VR-glasses display-enable sequencing, IoT sensor hubs, and any low-power mixed-signal front-end where PCB area is the limiting factor. The Go Configure Software Hub from Renesas provides a graphical design environment with simulation and hardware emulation support, which shortens development cycles compared to designing discrete analog logic.
When designing with the SLG46801, allocate the four programming pins (VDD, GND, SCL, SDA) on a test pad or header so the device can be reconfigured after assembly. The WLCSP variant requires careful PCB land-pattern design and reflow profiling because of its 0.5 mm pitch; the STQFN variant is recommended for prototypes that will be hand-reworked or inspected.

Typische Anwendungen
SLG46801 ist geeignet für 6 Anwendungs: Smart Ring Heart-Rate Sensor Conditioning, Smartwatch User-Interface Glue Logic, Fitness Band Battery and Charging Supervisor, VR Glasses Display-Enable Sequencing, IoT Sensor Hub Analog Front-End, Always-On Push-Button and Reset Sequencing.
Smart Ring Heart-Rate Sensor Conditioning
The SLG46801 is a strong fit for smart-ring heart-rate and SpO2 sensor signal conditioning because its two high-speed analog comparators can detect the small photodiode current swings from a PPG (photoplethysmography) sensor while the internal 25 MHz oscillator drives the LED timing. Combined with the configurable LUTs, the chip replaces a discrete op-amp + comparator + logic design in a 1.155 mm x 1.155 mm WLCSP, freeing PCB area for the battery and haptic driver. The 1.71 V to 5.5 V VDD range lets the same part operate from a coin-cell or a small Li-ion cell without level shifting. Designers typically pair the SLG46801 with a low-power PPG AFE and use Go Configure to implement blanking, ambient-light rejection, and motion-gating logic on-chip.

Smartwatch User-Interface Glue Logic
In smartwatches, the SLG46801 acts as the glue-logic companion to the main applications processor, handling button debouncing, capacitive-touch wake, display-enable sequencing, and haptic-driver control. The two analog comparators can directly sense a mechanical button or a touch electrode without an external op-amp, while the 10 kHz and 25 MHz oscillators drive the touch-scan timing and the PWM to the haptic driver. Using the SLG46801 in WLCSP cuts several mm2 of PCB area versus a discrete logic + comparator implementation, which is critical in watches with round displays. The MTP memory lets product teams iterate the touch and button behavior late in development without a board spin, and Go Configure provides simulation and hardware emulation for verification.
Empfohlen
Fitness Band Battery and Charging Supervisor
The SLG46801 is well suited as a charging and battery supervisor in fitness bands because its wide 1.71 V to 5.5 V VDD range spans the full Li-ion / Li-polymer charge profile from empty to fully charged, and the integrated analog comparators can directly monitor the battery voltage with a resistor divider. The on-chip counters and LUTs implement charge-time, current-limit, and over-temperature protection logic that would otherwise require a dedicated supervisor IC. The WLCSP package leaves more room for the battery cell, which is the dominant volume in this form factor, and the I2C ISP interface lets the firmware team adjust charge parameters after assembly. The Go Configure tool shortens the design cycle by simulating the timing behavior before tape-out.

VR Glasses Display-Enable Sequencing
In VR glasses, the SLG46801 provides deterministic power-up and power-down sequencing for the OLED display, the backlight driver, and the host SoC. The two internal oscillators (10 kHz and 25 MHz) supply the timing reference for the sequencing logic without an external clock, and the LUTs enforce the strict rail-on/rail-off order required by the OLED driver to prevent latch-up. The 1.155 mm x 1.155 mm WLCSP fits on the flexible PCB inside the temples of VR glasses where every mm2 is contested. Because the sequencing logic lives in the SLG46801, the host SoC boots into a known-good power state and can rely on the GreenPAK to hold the rails in reset until each block stabilizes - a critical requirement for OLED lifetime and image quality.

IoT Sensor Hub Analog Front-End
The SLG46801 serves as the analog front-end for compact IoT sensor hubs that aggregate temperature, humidity, motion, and ambient-light sensors before the data reaches a low-power MCU. Its two analog comparators can wake the system when a sensor crosses a threshold, the 10 kHz oscillator drives low-frequency sample timing, and the 25 MHz oscillator can clock a local PWM for sensor excitation. The wide VDD range supports both 3.3 V system rails and 1.8 V coin-cell operation. Because the SLG46801 holds its configuration in MTP memory, the wake-up thresholds and timing patterns are retained through battery replacement, and the I2C ISP interface allows the threshold map to be updated over the air through the host MCU.
Empfohlen
Always-On Push-Button and Reset Sequencing
The SLG46801 is ideal as an always-on push-button controller and reset sequencer in battery-powered products. The analog comparators detect the long press versus short press of a single mechanical button, the LUTs debounce the signal in hardware without waking the host MCU, and the on-chip counters generate the power-on reset delay and watchdog kick to the host. Operating from 1.71 V to 5.5 V lets the same part work from a deeply discharged Li-ion cell all the way to a regulated 3.3 V rail. The WLCSP package consumes under 1.5 mm2 of PCB area, leaving room for a larger battery. Designers pair the SLG46801 with a low-quiescent LDO so the entire always-on block draws microamps of current.

Wichtigste Unterscheidungsmerkmale

- Multi-Time Programmable memory with unlimited reconfiguration during development (vs. OTP GreenPAK predecessors)
Designhinweise
Allocate test pads or a 4-pin programming header for VDD, GND, SCL, and SDA on every PCB that uses the SLG46801. According to the SLG46801 In-System Programming Guide, these four pins are required for in-system write and read operations, and post-assembly reconfiguration is impractical without access to them. Place the test pads on a convenient edge or under the WLCSP shadow so a pogo-pin fixture can contact them in production.
Estimated: the SLG46801 WLCSP uses 0.5 mm ball pitch on a 9-ball grid, which requires non-solder-mask-defined (NSMD) land pads with a diameter of approximately 0.25 mm to 0.30 mm for reliable reflow. Confirm the exact recommendation in the Renesas package drawing before tape-out, and verify the PCB house can produce the required laser-drilled micro-via aspect ratio if you route signals to inner layers beneath the WLCSP. Use a 4-wire Kelvin contact on the VDD and GND pads if you need to measure quiescent current during characterization.
Do not assume the WLCSP variant of the SLG46801 is in mass production in October 2026; according to the Renesas launch announcement, the WLCSP is in sampling now and the STQFN is scheduled for mass production in November 2026. Prototype with the STQFN to avoid supply risk, and only switch to the WLCSP for the mass-production build. Also, double-check the VDD range - the SLG46801 covers 1.71 V to 5.5 V, but the closely related SLG46811 only covers 2.3 V to 5.5 V, which is too high for designs that need a 1.8 V nominal rail.
Compliance-Informationen
Compliance fields marked [DATA_NEEDED] because the Renesas product page does not list RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status in the verified web data. AEC-Q100 is not applicable because the SLG46801 targets consumer wearables, not automotive applications.
