COP8CCR9HVA8

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 features a Brownout Reset circuit operating between 4.17V and 4.5V. The component is available in 44-pin PLCC, WQFN, and TSSOP packages.

Feature Summary

• Virtual EEPROM capability allows emulation of non-volatile storage by copying data blocks between RAM and Flash memory.
• Dual clock system enables switching between high-speed and low-speed oscillators to optimize power consumption during idle or halt modes.
• Integrated EMI reduction technology utilizes gradual turn-on output drivers and internal smoothing filters to minimize radiated emissions.
• True in-system emulation support allows software debugging on final production boards without removing the microcontroller.

Applications

• Embedded control systems requiring low electromagnetic interference
• Applications needing in-system reprogrammability via MICROWIRE/PLUS interface
• Battery-powered devices utilizing low-power sleep and halt modes
• Systems requiring analog signal acquisition through integrated ADC channels

Procurement Notes

Verify the specific suffix against the official datasheet to confirm package type and temperature range. Ensure compatibility with existing development tools as the COP8 architecture requires specialized programming hardware. Confirm availability status as legacy components may have limited supply chains. Check RoHS compliance documentation for environmental regulations.

Selection Notes

Select this component when 32 kbytes of Flash memory and multiple communication interfaces are required in an 8-bit architecture. Consider the COP8CCR9 variant specifically for applications demanding a higher Brownout Reset threshold compared to the CBR9 series. Evaluate pin count requirements across available packages to ensure sufficient I/O for the design.

Part Context

This part belongs to the COP8CBR9/COP8CCR9/COP8CDR9 family of 8-bit microcontrollers. These devices share a common core architecture but differ in voltage thresholds and peripheral configurations. The COP8CCR9 is distinguished by its specific Brownout Reset voltage range, differentiating it from the lower-voltage CBR9 and the no-BOR CDR9 variants within the same product line.
