COP8CCR9IMT7/NOPB

Overview

The COP8CCR9IMT7/NOPB is an 8-bit CMOS Flash microcontroller from the COP8CxR9 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 with up to 16 channels, two USARTs, and three timers. It supports dual clock operation with a high-speed oscillator up to 10 MHz and a low-speed oscillator at 32.768 kHz. The part operates within a voltage range of 4.5V to 5.5V for temperatures between -40°C and +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
• In-system programmability through MICROWIRE/PLUS serial interface

Applications

• Embedded control systems requiring large memory and low electromagnetic interference
• Applications needing in-system reprogrammability and software updates
• Development and pre-production environments utilizing final production units for testing
• Systems requiring analog signal processing with integrated A/D conversion

Procurement Notes

Verify the specific suffix IMT7 corresponds to the TSSOP-48 package and the extended temperature range (-40°C to +125°C) as defined in the COP8CxR9 datasheet. Confirm that the NOPB designation indicates RoHS compliance. Ensure compatibility with existing design tools and development hardware supporting the COP8 architecture before procurement.

Selection Notes

Select this component when a modified Harvard architecture with code-efficient instruction sets is required. It is suitable for designs needing high I/O pin efficiency and multiple communication interfaces like USART and MICROWIRE/PLUS. Consider the dual clock modes for power management strategies involving idle and halt states. Verify that the 4.5V to 5.5V operating voltage aligns with the system power supply constraints.

Part Context

This microcontroller belongs to the COP8CxR9 series, which also includes the COP8CBR9 and COP8CDR9 variants. These devices share the same core architecture and memory size but differ in brownout reset specifications and temperature ranges. The COP8CCR9 specifically includes a brownout reset feature and supports the higher temperature range compared to the CBR9 variant.
