CP80C88-2Z

The CP80C88-2Z is an 80C88 CMOS microprocessor IC featuring a single 16-bit core running at 8 MHz, designed for embedded applications that require a through-hole 40-PDIP package and 5 V I/O. It combines a 16-bit internal architecture with an 8-bit external data bus for use in systems that need compact processing capability with straightforward interfacing.

Built on a static CMOS design with low-power modes and RoHS-compliant packaging, the CP80C88-2Z is suited to embedded and consumer-qualified designs where compatibility with legacy 8088/8086 software and hardware is important.

Key Features

• Core & Architecture  80C88 core with a 16-bit internal architecture and an 8-bit external data bus, providing a balance between data-path width and external interface simplicity.
• Clock Speed  Operates at 8 MHz (CP80C88-2Z variant), enabling deterministic, low-frequency embedded processing.
• Voltage I/O  5 V I/O levels compatible with TTL-family interfaces.
• Memory Addressing  Up to 1 MB of direct memory addressing capability as specified in the device family datasheet.
• Power Efficiency  Completely static CMOS design with low-power characteristics: ICCSB (standby) specified up to 500 µA maximum and ICCOP (operating) around 10 mA/MHz maximum in the datasheet.
• Compatibility  Direct software compatibility with 80C86, 8086, and 8088 architectures and compatibility with NMOS 8088 hardware per the datasheet.
• Package & Mounting  40-PDIP / 40-DIP (0.600", 15.24 mm) through-hole package for easy prototyping, repair, and legacy PCB reuse.
• Operating Temperature  Consumer-grade range of 0 °C to 70 °C.
• Environmental Compliance  RoHS compliant; Pb-free plastic packaged option noted in the product documentation.
• Bus-Hold & I/O Handling  Includes bus-hold circuitry as noted in the datasheet to simplify external pull-up requirements on bus lines.

Typical Applications

• Embedded control and logic  Use as a general-purpose microprocessor for embedded control tasks where an 8 MHz clock and 16-bit internal processing meet system requirements.
• Legacy system maintenance and upgrades  Drop-in-friendly option for systems that rely on 8088/8086 software compatibility and industry-standard pinouts in a 40-DIP package.
• Through-hole prototyping and repair  40-PDIP through-hole mounting simplifies breadboard work, prototyping, and field-level replacement on legacy PCBs.
• Low-power consumer embedded devices  Well-suited for consumer designs operating within 0 °C to 70 °C that benefit from the device’s static CMOS low-power behavior.

Unique Advantages

• Direct legacy software compatibility:  Datasheet-level compatibility with 80C86, 8086, and 8088 software enables reuse of existing codebases and reduces firmware migration effort.
• Static CMOS low-power operation:  Static design and documented low standby and operating currents reduce system power consumption and simplify power budgeting.
• 1 MB direct addressing:  Support for up to 1 MB of direct memory addressing allows straightforward interfacing with legacy memory maps and larger memory spaces.
• Through-hole 40-PDIP packaging:  Classic 40-pin DIP footprint eases prototyping, manual assembly, and replacement on established board designs.
• RoHS-compliant package option:  Pb-free packaging documented in the product information supports environmental compliance requirements.
• Bus-hold circuitry:  On-chip bus-hold reduces the need for external pull-up resistors on bus lines, simplifying BOM and board routing.
