Renesas Electronics is sampling the SLG46801, a 9-ball configurable mixed-signal device that the company identifies as the smallest member of its GreenPAK family. The part combines an ultra-small footprint with multi-time programmability, a distinction that matters for engineers iterating on compact board designs.

What does the SLG46801 change for designers?

GreenPAK devices let engineers configure analog and digital mixed-signal functions — effectively replacing small discrete logic and analog circuits — in a single programmable chip. Until now, the trade-off in the family has been between footprint and flexibility: one-time programmable (OTP) parts keep size down, while multi-time programmable (MTP) versions have historically required larger packages.

The SLG46801 collapses that trade-off. Renesas highlights that the 9-ball device offers multi-time programmability in what it calls an ultra-compact footprint, giving designers the ability to reconfigure the device during development — or rework it in production — without stepping up to a larger package.

For compact products, where every square millimeter of board area carries a cost, that combination is the core commercial pitch of the part.

Where does it fit in the GreenPAK lineup?

Renesas positions the SLG46801 at the small end of the GreenPAK portfolio:

• Package: 9-ball, the company's smallest GreenPAK device
• Programmability: multi-time programmable, unlike OTP variants
• Target: compact products with tight board constraints
• Status: sampling now, per Renesas

Why does multi-time programmability matter?

OTP devices lock in a configuration at fabrication. MTP parts such as the SLG46801 allow the configuration to be rewritten, which shortens development cycles when analog thresholds, timing or logic functions need adjustment after initial programming.

In space-constrained applications — wearables, sensors, small IoT nodes and other compact products Renesas names as the target — reworking a programmable device in place is often cheaper than respinning a board around fixed-function discretes.

What comes next?

The device is in sampling now; Renesas has not yet disclosed volume pricing or full production timing. Expect broader availability details — and competitive responses from other configurable mixed-signal suppliers — as the part moves from sampling toward production, with the small-footprint MTP combination setting the competitive benchmark.
