RB80526PZ800256

The RB80526PZ800256 is an Intel® Pentium® III processor microprocessor IC featuring a single 32‑bit core running at 800 MHz. Designed for embedded and commercial microprocessor applications, it delivers predictable single‑core performance and DSP acceleration via MMX instructions.

This device is supplied in a 370‑PPGA (49×49) package with through‑hole mounting and operates over a commercial temperature range, making it suitable for a range of board‑level embedded designs that require a legacy Pentium III architecture.

Key Features

• Processor Core Intel® Pentium® III single core, 32‑bit architecture for standard embedded processing tasks.
• Clock Speed 800 MHz operating frequency to meet moderate performance requirements.
• DSP Extensions MMX co‑processor support for enhanced media and signal processing instruction sets.
• Power I/O voltage specified at 1.75 V for systems engineering and power budgeting.
• Package & Mounting 370‑PPGA (49×49) package case with through‑hole mounting for board‑level installations and retrofit applications.
• Thermal Range Commercial operating temperature from 0 °C to 80 °C for standard commercial environments.
• Compliance RoHS compliant to meet common environmental requirements.
• Graphics No integrated graphics acceleration; suitable where discrete or no graphics is required.

Typical Applications

• Embedded Systems — Single‑core 32‑bit processing for control, I/O handling, and computation in embedded products.
• Commercial Electronics — Commercial‑grade processor suited to non‑industrial, non‑automotive electronic equipment operating within 0 °C to 80 °C.
• Board‑Level Designs & Retrofits — 370‑PPGA through‑hole package supports board upgrades and designs that require this package style.
