COP8CCR9HVA8/NOPB

Overview

The COP8CCR9HVA8/NOPB is an 8-bit CMOS Flash microcontroller from the COP8 family, featuring 32 kbytes of Flash program memory and 1 kbyte of volatile RAM. It integrates a 10-bit Analog-to-Digital Converter with up to 16 channels, two USARTs, and three timers. The device supports dual clock operation with a clock doubler for speeds up to 20 MHz. It includes Virtual EEPROM functionality using Flash memory and offers in-system programmability via MICROWIRE/PLUS. Operating voltage ranges from 4.17V to 4.5V with Brownout Reset enabled.

Feature Summary

• Virtual EEPROM capability allows emulation of nonvolatile variables by copying data between RAM and Flash memory.
• Dual clock system enables switching between high-speed and low-speed oscillators to minimize power dissipation.
• True in-system emulation allows software debugging using final production boards without specialized hardware.
• EMI reduction technology includes low EMI clock circuits and gradual turn-on output drivers.

Applications

• Applications requiring full-featured, in-system reprogrammable control with large memory capacity.
• Systems needing low electromagnetic interference (EMI) emissions.
• Embedded controllers utilizing analog signal processing via the integrated A/D converter.
• Devices requiring serial communication through dual USART interfaces.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm package type and temperature range. Confirm that the component meets RoHS compliance requirements if applicable to your assembly process. Check current availability status as this product line may have limited supply or end-of-life implications.

Selection Notes

Select this microcontroller when a modified Harvard architecture is required for efficient data table access from program memory. Consider the COP8CCR9 series for designs needing a specific 4.17V to 4.5V operating voltage window with Brownout Reset protection. Ensure the application benefits from the code-efficient instruction set and single-cycle execution capabilities.

Part Context

This component belongs to the COP8CBR9/COP8CCR9/COP8CDR9 family of 8-bit CMOS Flash microcontrollers. These devices share core architectural features such as 32k Flash memory and advanced peripherals like Virtual EEPROM and high-speed timers. The COP8CCR9 variant specifically distinguishes itself with a defined Brownout Reset voltage range suitable for 4.5V nominal systems.

Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the COP8CBR9 and COP8CDR9 families. Verify functional equivalence regarding Brownout Reset thresholds and operating voltage ranges before substitution.
