CP80C88Z

The CP80C88Z is a 1‑core 80C88 CMOS microprocessor in a 40‑pin PDIP through‑hole package, operating at 5 MHz and with 5 V I/O. Designed for embedded systems, it delivers a 16‑bit internal architecture with an 8‑bit external data bus for compact, low‑power control applications.

Its design supports both small‑system (Minimum) and larger‑system (Maximum) modes, enabling flexible deployment from simple embedded controllers to multiprocessing environments while maintaining low static and active current characteristics.

Key Features

• Core and Architecture – 80C88 core with a 16‑bit internal architecture and 8‑bit external data bus interface for efficient data handling and legacy software support.
• Operating Speed – 5 MHz rated clock frequency for timing‑predictable embedded control tasks.
• Power and Efficiency – Completely static CMOS design with low standby and active currents (standby ICCSB up to 500 µA; operating ICCOP up to 10 mA/MHz) for reduced power consumption in both idle and active modes.
• Memory and Addressing – 1 MB direct memory addressing capability with 24 operand addressing modes for flexible memory mapping and code/data placement.
• Compatibility – Direct software compatibility with 80C86, 8086, and 8088; compatible with NMOS 8088 systems and TTL‑compatible signaling (except CLOCK) for reuse of existing designs and software assets.
• System Modes – Configurable Minimum and Maximum operation modes to optimize for small single‑chip systems or larger multiprocessing applications.
• Bus and I/O – Bus‑hold circuitry eliminates external pull‑ups on data lines, simplifying board design and increasing signal integrity.
• Package and Mounting – 40‑pin PDIP (0.600", 15.24 mm) through‑hole package for ease of prototyping and retrofit into existing through‑hole assemblies.
• Environmental and Qualification – Consumer qualification with RoHS compliance and an operating temperature range of 0 °C to 70 °C.

Typical Applications

• Embedded Control – Compact controllers and appliance control where a 5 MHz CMOS microprocessor with low standby current and through‑hole packaging is suitable.
• Legacy x86‑Compatible Systems – Designs requiring direct software compatibility with 80C86/8086/8088 code bases for maintenance, retrofit, or incremental upgrades.
• Multiprocessing/Expansible Systems – Larger applications that leverage the Maximum mode for system expansion and multiprocessing arrangements.

Unique Advantages

• Direct Software Reuse: Enables reuse of existing 80C86/8086/8088 software, reducing development time and preserving legacy investments.
• Flexible System Configuration: Minimum and Maximum operation modes let designers optimize the same device for small standalone systems or larger multiprocessing environments.
• Low‑Power CMOS Design: Static CMOS architecture with low standby and predictable operating currents minimizes system power budgets.
• Board‑Level Simplicity: Bus‑hold circuitry reduces the need for external pull‑ups, simplifying BOM and PCB routing.
• Prototyping‑Friendly Package: 40‑pin PDIP through‑hole package supports straightforward prototyping, testing, and replacement in legacy sockets.
• Regulatory Compliance: RoHS‑compliant construction supports environmentally conscious manufacturing and procurement.
