COP8CCR9IMT8/NOPB

Overview

The COP8CCR9IMT8/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 via Flash memory and offers in-system programmability through MICROWIRE/PLUS. Operating voltage ranges from 4.5V to 5.5V at temperatures up to +125°C, or 2.7V to 5.5V up to +85°C.

Feature Summary

• Integrated Virtual EEPROM capability allows emulation of non-volatile storage using Flash memory routines.
• Dual clock system with high-speed and low-speed oscillators enables flexible power management and wake-up modes.
• EMI reduction technology includes low EMI clock circuits and gradual turn-on output drivers to minimize radiated emissions.
• True in-system emulation support allows debugging on final production boards using standard connectors.

Applications

• Applications requiring low electromagnetic interference (EMI) in embedded control designs
• Systems needing in-system reprogrammability and software updates via serial interfaces
• Industrial controllers operating in extended temperature environments up to +125°C
• Battery-powered devices utilizing dual-clock power saving modes

Procurement Notes

Verify the specific suffix against the official Texas Instruments datasheet SNOS535I to confirm package type and temperature range. Ensure compatibility with existing development tools as the COP8 architecture requires specific hardware and software support for programming and emulation. Check for end-of-life status or alternative recommendations from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when high integration of analog and digital peripherals is required within an 8-bit architecture. The COP8CCR9 variant is suitable for applications demanding operation at higher voltages (4.5V–5.5V) and extended temperatures (+125°C). Consider the available I/O count and timer resources relative to system complexity. Evaluate the need for Virtual EEPROM if persistent data storage without external chips is necessary.

Part Context

This part belongs to the COP8CBR9/COP8CCR9/COP8CDR9 family of 8-bit CMOS Flash microcontrollers. These devices share a common core architecture but differ in Brownout Reset configurations and operating voltage ranges. The COP8CCR9 specifically includes a Brownout Reset feature with a trip level between 4.17V and 4.5V, distinguishing it from the CDR9 which lacks this feature.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. Consult Texas Instruments documentation for potential obsolescence notices or recommended upgrades within the COP8 family or newer architectures.

FAQ

What is the maximum operating frequency of the COP8CCR9?

The device supports operation up to 20 MHz when using a 10 MHz oscillator with the clock doubler enabled.

How does the Virtual EEPROM function work?

Virtual EEPROM emulates variable amounts of EEPROM by initializing nonvolatile variables from Flash Memory and periodically restoring them to Flash Memory using boot ROM routines.

Does the COP8CCR9 support in-system programming?

Yes, it supports true in-system programming and real-time emulation via the MICROWIRE/PLUS serial interface or custom user-defined routines.
