COP8CBE9HVA7

Overview

The COP8CBE9HVA7 is an 8-bit microcontroller from the COP800 family, manufactured by National Semiconductor. It features a CMOS architecture with on-chip FLASH memory and operates at a maximum clock frequency of 20 MHz. The device is housed in a 44-pin Plastic Quad Flatpack (PQCC) package. It supports a wide operating temperature range from -40°C to 85°C and includes 38 I/O lines. Key integrated peripherals include PWM channels and an ADC, making it suitable for complex control applications requiring robust embedded processing capabilities.

Feature Summary

• Integrated 8-bit COP800 CPU core with FLASH memory for code storage
• Supports high-speed operation up to 20 MHz clock frequency
• Includes analog-to-digital conversion (ADC) and pulse-width modulation (PWM) channels
• Provides extensive I/O connectivity with 38 available lines

Applications

• Industrial control systems requiring robust 8-bit processing
• Consumer electronics utilizing FLASH-based firmware updates
• Automotive subsystems within specified temperature ranges
• General-purpose embedded controllers with analog signal monitoring needs

Procurement Notes

Verify the manufacturer source carefully, as National Semiconductor's microcontroller assets were acquired by Texas Instruments. Ensure the part number suffix matches the specific package and temperature grade requirements for your design. Confirm availability through authorized distributors handling legacy or TI-managed inventory to avoid counterfeit components.

Selection Notes

Select this component when an 8-bit architecture with integrated FLASH and analog peripherals is required. Compare against other COP8 variants based on memory size and pin count. Consider the PQCC package constraints for PCB layout. Evaluate if the 20 MHz speed meets real-time processing demands compared to newer 16-bit or 32-bit alternatives.

Part Context

This device belongs to the COP8SG/COP8C family of 8-bit microcontrollers. These parts are characterized by their high integration, combining CPU, memory, and I/O on a single chip. The COP8C series specifically denotes versions with internal FLASH memory, distinguishing them from OTP or ROM-based counterparts in the same family.

Replacement Considerations

Check for direct form-fit-function replacements within the COP8C or COP8SG families. Verify pin compatibility and memory capacity. Note that Texas Instruments may list equivalent or successor parts; consult official cross-reference guides for validated substitutions.
