Z8L18220FSG

The Z8L18220FSG is a Zilog Z8S180 microprocessor in a 100‑pin QFP surface‑mount package. It integrates a single 8‑bit Z8S180 core running at 20 MHz and is supplied with 3.3 V I/O.

Designed for embedded and commercial applications, the device includes a DRAM controller and ASCI interface while meeting RoHS requirements. Its combination of an 8‑bit core, standard commercial temperature range, and compact QFP package targets embedded system designs that require moderate processing at 20 MHz.

Key Features

• Core  Z8S180 single 8‑bit core operating at 20 MHz, suitable for typical embedded control workloads.
• Memory  On‑chip DRAM controller support, enabling integration with external DRAM memory subsystems.
• Power and I/O  3.3 V I/O supply level for compatibility with low‑voltage embedded peripherals.
• Interfaces  Includes ASCI as an additional interface for serial communication needs.
• Package and Mounting  100‑QFP package in a surface‑mount form factor for PCB assembly and density considerations.
• Operating Range  Commercial grade with an operating temperature range of 0 °C to 70 °C.
• Regulatory  RoHS compliant.

Typical Applications

• Embedded control systems  8‑bit processing at 20 MHz makes the device suitable for general embedded control tasks in commercial products.
• Commercial electronic products  Rated for commercial temperature range (0 °C to 70 °C), appropriate for a wide range of non‑industrial, non‑automotive devices.
• Memory‑subsystem designs  Built‑in DRAM controller support facilitates designs that incorporate external DRAM for additional system memory.

Unique Advantages

• Balance of performance and simplicity  A 20 MHz Z8S180 core delivers easily predictable 8‑bit performance for deterministic embedded tasks.
• Integrated memory support  DRAM controller integration reduces external glue logic and simplifies memory subsystem design.
• Industry‑standard I/O voltage  3.3 V I/O compatibility aligns with common low‑voltage peripheral interfaces.
• Compact, surface‑mount package  100‑QFP surface‑mount package supports modern PCB assembly and space‑constrained layouts.
• Commercial grade reliability  Specified operating range and RoHS compliance support mainstream commercial product development and procurement.
