COP8CDR9LVA8

Overview

The COP8CDR9LVA8 is an 8-bit CMOS Flash microcontroller from the COP8CBR/CCR/CDR9 family. It features 32 kbytes of Flash program memory, 1 kbyte of volatile RAM, and a 10-bit successive approximation analog-to-digital converter supporting up to 16 channels. The device operates at frequencies up to 20 MHz with instruction cycles as fast as 0.5 µs. It supports dual clock operation with a low-speed oscillator for power saving modes. Operating voltage ranges from 2.7V to 5.5V across temperatures from -40°C to +85°C. It includes two USARTs, three timers, MICROWIRE/PLUS interface, and in-system programming capabilities.

Feature Summary

• Integrated Virtual EEPROM functionality using Flash program memory for nonvolatile data storage.
• EMI reduction technology featuring gradual turn-on output drivers and internal smoothing filters.
• True in-system emulation capability allowing software debugging on production boards.
• Dual clock system with high-speed and low-speed oscillators for optimized power management.

Applications

• Embedded control systems requiring low electromagnetic interference.
• Applications needing in-system reprogrammability via serial interfaces.
• Battery-powered devices utilizing low-power idle and halt modes.
• Systems requiring analog signal processing with integrated ADC.

Procurement Notes

Verify the specific suffix LVA8 against the official datasheet to confirm package type and temperature range. Confirm availability status as older generation components may have limited supply or end-of-life status. Ensure ESD handling procedures are followed during storage and assembly due to MOS gate sensitivity.

Selection Notes

Select this component when a modified Harvard architecture with code-efficient single-byte instructions is required. Consider the COP8CDR9 variant specifically if Brownout Reset is not needed, distinguishing it from CBR9 and CCR9 models. Evaluate the need for 16-channel ADC support and dual USARTs before choosing over simpler variants.

Part Context

This part belongs to the COP8CBR9/COP8CCR9/COP8CDR9 series manufactured by Texas Instruments. These devices share a common core architecture but differ in Brownout Reset configurations and operating voltage ranges. The COP8CDR9 specifically lacks the Brownout Reset feature found in the CBR9 and CCR9 counterparts.

Replacement Considerations

Direct replacements within the same family include COP8CBR9 and COP8CCR9, noting differences in Brownout Reset presence and voltage thresholds. Verify pin compatibility and software instruction set equivalence when substituting.
