Renesas Introduces Smallest Configurable GreenPAK IC with MTP in Ultra-Compact WLCSP and STQFN Packages

Renesas Electronics Corporation announced the SLG46801, the industry’s smallest GreenPAK configurable mixed-signal device offered in both WLCSP and STQFN packages. The 9-ball WLCSP measures just 1.155mm × 1.155mm and combines an ultra-small footprint with multi-time programmability, enabling designers to reduce board space in compact products such as smart rings, smartwatches, fitness bands, VR glasses, and portable electronics.

As consumer devices become smaller and feature-rich, designers need to integrate additional functionality while reducing component count, PCB area, and bill-of-materials cost. The SLG46801 addresses these requirements by combining commonly used analog, timing, and logic functions in a compact, low-power device that can complement an MCU or replace multiple discrete components.

The SLG46801 integrates two high-speed analog comparators, configurable lookup tables, counters and delays, 10kHz and 25MHz oscillators, voltage-tolerant GPIOs, and an I²C-compatible serial interface. These resources support sensing, control, glue-logic, timing, and system housekeeping functions in applications across consumer electronics, handheld devices, smart-home systems, networking and communications, computing and storage, industrial control, and IoT sensor nodes (more info).
