COP8CCR9IMT8

Overview

The COP8CCR9IMT8/NOPB is an 8-bit CMOS Flash microcontroller from the COP8CBR9/CCR9/CDR9 family, manufactured by Texas Instruments. It features 32 kbytes of Flash program memory and 1 kbyte of volatile RAM. The device includes a 10-bit successive approximation analog-to-digital converter supporting up to 16 channels, two USARTs with on-chip baud generators, and three timers. It operates within a supply voltage range of 4.17V to 4.5V and supports frequencies up to 20 MHz from a 10 MHz oscillator. The component is housed in a 48-pin TSSOP package and functions across a temperature range of -40°C to +125°C.

Feature Summary

• Virtual EEPROM capability using Flash program memory for nonvolatile data storage
• EMI reduction technology including low EMI clock circuitry and gradual turn-on output drivers
• True in-system emulation and real-time debugging support via standard connectors
• Dual clock operation with high-speed and low-speed oscillators for power saving modes

Applications

• Embedded control systems requiring large memory and low electromagnetic interference
• Applications needing in-system reprogrammability and virtual EEPROM functionality
• Development and pre-production environments utilizing true in-system emulation tools

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm package type and temperature range. Confirm that the required voltage range aligns with the CCR9 variant specifications. Check current availability status as legacy components may have limited stock or end-of-life implications. Ensure compatibility with existing development tools for the COP8 architecture.

Selection Notes

Select this component when a robust 8-bit controller with significant Flash memory and integrated analog peripherals is required. The CCR9 variant is specifically suited for applications operating at higher voltage levels compared to the CBR9. Consider the package options available for the COP8CCR9 series to match board space constraints. Evaluate the need for Brownout Reset features which are present in this variant.

Part Context

This microcontroller belongs to the COP8CBR9/COP8CCR9/COP8CDR9 family, which shares a common core architecture but differs in voltage ranges and Brownout Reset configurations. The COP8CCR9 variant is distinguished by its specific operating voltage window and extended temperature capabilities. This family utilizes a modified Harvard architecture and offers code-efficient instruction sets designed for compact program memory utilization.
