EZ80190AZ050EG

The EZ80190AZ050EG is a Zilog eZ80 microprocessor IC featuring a single eZ80 core with an 8-bit bus architecture operating at 50 MHz. It targets embedded designs that require a compact, industrial-grade MPU with standard 3.3 V I/O and common serial interfacing.

Packaged in a 100-lead VQFP (14 × 14 mm) surface-mount package, the device combines eZ80 processing capability with an extended operating temperature range and RoHS compliance for industrial applications. A full product specification and datasheet are available for system-level integration and detailed design reference.

Key Features

• Core and Architecture Single eZ80 core with an 8-bit bus width, optimized for embedded control and legacy Z80-compatible applications.
• Performance 50 MHz operating clock speed for responsive embedded processing suited to control and interfacing tasks.
• Power and I/O 3.3 V I/O voltage level compatible with common embedded logic and peripheral interfaces.
• Interfaces On-chip support for I2C for system and sensor communications (additional peripheral details are documented in the product specification).
• Package and Mounting 100-lead VQFP package (14 × 14 mm), surface-mount for standard PCB assembly and space-efficient placement.
• Industrial Grade and Temperature Range Rated for industrial operation with an ambient temperature range of −40 °C to 105 °C.
• Regulatory RoHS compliant, meeting common environmental directives for electronic components.

Unique Advantages

• Compact single-chip processing: The single eZ80 core delivers embedded processing in a small 100-VQFP footprint, simplifying board layout and minimizing BOM count.
• Standard 3.3 V I/O: Native 3.3 V I/O enables direct interfacing with modern sensors, peripherals, and logic families without level-shifting.
• Industrial temperature capability: −40 °C to 105 °C rating supports deployment in harsh or temperature-variable environments.
• Surface-mount package for production: 100-VQFP (14 × 14 mm) supports automated assembly and high-density PCB designs.
• Documented specification: Comprehensive product specification and register/core documentation are available to support design, validation, and firmware development.
