COP8CBR9HVA8/NOPB

Overview

The COP8CBR9HVA8/NOPB is an 8-bit CMOS Flash microcontroller featuring 32 kbytes of program memory and a virtual EEPROM capability. It integrates a 10-bit successive approximation 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 high-speed processing. It includes a brownout reset feature active between 2.7V and 2.9V. The component operates within a temperature range of -40°C to +85°C and utilizes a 44-pin PLCC package.

Feature Summary

• Integrated Virtual EEPROM functionality using Flash program memory for nonvolatile data storage emulation.
• Dual clock system with a clock doubler enabling high-speed operation and low-power idle modes.
• Built-in electromagnetic interference reduction circuitry including gradual turn-on output drivers.
• True in-system programming and emulation capabilities via MICROWIRE/PLUS serial interface.

Applications

• Embedded control systems requiring large program memory and low electromagnetic emissions.
• Applications necessitating in-system reprogrammability and software updates.
• Devices utilizing analog sensor inputs processed by the integrated 10-bit ADC.
• Systems employing asynchronous serial communication through dual USART peripherals.

Procurement Notes

Verify the specific suffix HVA8 against the official Texas Instruments datasheet SNOS535I to confirm pin compatibility and voltage thresholds. Confirm that the 44-PLCC package matches the target board layout. Ensure design compliance with the specified 2.7V to 2.9V brownout reset window. Check current availability status as production data may indicate end-of-life or limited supply conditions.

Selection Notes

Select this component when a modified Harvard architecture is required for efficient code execution and direct access to constant data tables. Choose the COP8CBR9 variant specifically for its integrated brownout reset protection. Consider the 44-pin PLCC package if surface mount plastic leaded chip carrier form factors are mandated. Evaluate the 10-bit ADC resolution against application signal requirements before finalizing the selection.

Part Context

This part belongs to the COP8CBR9/COP8CCR9/COP8CDR9 family of 8-bit CMOS Flash microcontrollers manufactured by Texas Instruments. The COP8 core provides a unique instruction set optimized for code efficiency and single-cycle execution. The family shares architectural similarities but differs in brownout reset configurations and operating temperature ranges. This specific model represents the standard commercial grade variant with brownout protection.

Replacement Considerations

Consult the official Texas Instruments documentation for confirmed substitute part numbers within the COP8CCE9 or COP8SCR9 series. Verify electrical specifications and pinouts before substituting. No alternative part numbers are explicitly listed in the provided source material for direct replacement.
