Automotive GreenPAK Programmable Mixed-Signal ICs

AEC‑Q100 qualified and optimized for harsh environments, automotive GreenPAK devices integrate logic, timing, monitoring, and control functions into a single compact device. Designed for automotive support functions such as power sequencing, signal conditioning, fault detection, and system monitoring, these programmable mixed-signal ICs enable deterministic, hardware-based control without the need for firmware while reducing reliance on discrete components and offloading MCU tasks.

Used across ADAS, infotainment, electrification, and body electronics, automotive GreenPAK supports flexible, scalable integration in modern vehicle architectures, helping reduce BOM, improve reliability, and ensure predictable system behavior.

Why Automotive GreenPAK

Deterministic Hardware

Hardware‑Implemented Logic, Timing & Monitoring

GreenPAK implements functions using configurable hardware blocks (logic, timing, comparators/monitoring depending on device) rather than executing firmware instructions on a CPU. Mechanically, that means signal processing and state behavior are driven by hardware paths and timing resources, not by task scheduling, interrupt latency, or software state. In automotive supporting functions—like resets, power sequencing, gating, debounce, watchdog supervision, and simple interlocks—this hardware implementation can provide predictable timing behavior and immediate response consistent with the configured logic and timing resources.

GreenPAK enables deterministic hardware-based control by implementing logic functions directly in configurable hardware blocks.

Replacing Discrete

Functional Integration & Discrete Replacement

Automotive GreenPAK enables multiple supporting system functions—such as logic gating, timing, reset shaping, monitoring, and signal conditioning—to be implemented within a single configurable device rather than across multiple discrete components. Mechanically, this shifts functionality from distributed discrete logic and timing ICs into one programmable mixed‑signal IC, reducing interconnects, simplifying routing, and consolidating supporting circuitry. This integration approach can translate directly into PCB footprint reduction and lower BOM complexity, particularly in space‑constrained automotive modules.

MCU Offloading

Glue Logic + Interface Bridging Around MCUs/ASICs

Automotive designs commonly require “between‑chips” functions: gating signals, combining conditions, translating control intents, sequencing enables, creating delays, shaping pulses, and monitoring thresholds. GreenPAK’s mechanism is to provide a programmable interconnect and mixed‑signal function set that sits adjacent to the MCU/ASIC, implementing these supporting behaviors locally. This reduces the need to consume MCU pins, MCU cycles, or add multiple discrete logic/timing components—because the behavior is realized inside a single configurable device that can be adapted as requirements evolve.
