• True in-system emulation capability allowing software and hardware debugging on final production boards.
• Virtual EEPROM capability enabling nonvolatile variable storage by copying data blocks between RAM and Flash memory.
• Dual clock system with high-speed and low-speed oscillators for flexible power saving modes.

Applications

• Embedded control systems requiring large program memory and low electromagnetic interference.
• Applications needing in-system reprogrammability and real-time emulation during development.
• Systems utilizing virtual EEPROM for data retention without dedicated EEPROM hardware.
• Power-sensitive designs utilizing dual clock operation and HALT/IDLE power save modes.

Procurement Notes

Verify the specific package type and temperature grade corresponding to the HLQ8 suffix against the official datasheet, as the COP8CBR9 family spans multiple packages and operating ranges. Confirm availability status, as this product line may be subject to end-of-life notices or limited distribution. Ensure compliance with RoHS directives if required for the target application.

Selection Notes

Select this component when an 8-bit architecture with substantial 32k Flash memory and integrated analog conversion is required. Consider the COP8CBR9 series for designs prioritizing EMI reduction and true in-system emulation capabilities. Evaluate the need for Virtual EEPROM versus external nonvolatile memory solutions based on endurance requirements and code efficiency needs.
