Overview of RB80526RY850128 – IC MPU 1 850MHZ 370PPGA
RB80526RY850128 is an Intel microprocessor from the Pentium III series, featuring an Intel® Celeron® single 32‑bit core clocked at 850 MHz. It is presented in a 370‑PPGA (49×49) through‑hole package and is targeted for embedded applications that require a socketable, commercial‑grade processor.
The device includes MMX co‑processor support, a commercial operating temperature range of 0 °C to 80 °C, and RoHS compliance, making it suitable for a range of embedded and industrial computing designs where a single‑core 32‑bit processor is appropriate.
Key Features
- Core Single Intel® Celeron® 32‑bit core running at 850 MHz for single‑threaded embedded workloads.
- Digital Signal Support (MMX) Includes MMX co‑processor support for enhanced integer multimedia and signal processing operations.
- Package 370‑PPGA (49×49) / 370‑PGA package providing a socketable form factor for through‑hole mounting and field replacement.
- Mounting Through Hole mounting type suitable for socketed board designs and mechanical retention.
- Grade and Temperature Range Commercial grade device with an operating range from 0 °C to 80 °C for indoor and controlled environment applications.
- Graphics No graphics acceleration included; designed for CPU‑centric embedded tasks.
- Environmental Compliance RoHS compliant for regulatory conformance in qualified applications.
Typical Applications
- Embedded controllers Single‑core, 32‑bit processing at 850 MHz for control and orchestration tasks in embedded systems.
- Industrial automation Socketable 370‑PPGA package and commercial temperature rating support replacement and serviceability in industrial equipment operating in controlled environments.
- Legacy system maintenance Fits designs that require a through‑hole, socketable Intel processor for repair or continuity of older platforms.
- Development and evaluation boards Through‑hole, socketable package allows easy prototyping, swapping, and testing during development cycles.
Unique Advantages
- Socketable 370‑PPGA package: Enables easy insertion, replacement, and field servicing in boards built for PGA processors.
- MMX co‑processor support: Provides additional integer multimedia and signal processing capability where that instruction set is used.
- Commercial operating range: 0 °C to 80 °C rating aligns with many indoor and controlled environment embedded applications.
- RoHS compliant: Meets environmental restrictions for products requiring lead‑free components.
- Single‑core simplicity: A 32‑bit single‑core architecture simplifies software model and integration for legacy and resource‑constrained systems.
