COP8CBE9IMT9

Overview

The COP8CBE9IMT9 is an 8-bit CMOS Flash microcontroller from the COP8 family, featuring 8k bytes of program memory and 256 bytes of RAM. It integrates a 10-bit A/D converter with up to 16 channels, USART, and two 16-bit timers. The device supports in-system programming via MICROWIRE/PLUS and includes virtual EEPROM functionality. Operating voltage ranges from 2.7V to 5.5V, with a low brownout reset threshold of 2.7V to 2.9V. It is housed in a 48-pin TSSOP package and operates within a temperature range of 0°C to +70°C.

Feature Summary

• Virtual EEPROM capability using Flash program memory for nonvolatile data storage
• EMI reduction technology including low radiated emissions and gradual turn-on output drivers
• Dual clock operation with high-speed and low-speed oscillators for power saving modes
• True in-system emulation support for software debugging on production boards

Applications

• In-system reprogrammable controller applications requiring large memory
• Embedded control designs needing low electromagnetic interference
• Development and pre-production environments using final production devices
• Applications utilizing virtual EEPROM for variable data retention

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm package type and temperature range. Ensure the component matches the required brownout voltage specifications for your application. Confirm availability status as older components may have limited supply or end-of-life status. Cross-reference the pinout with your PCB design to ensure compatibility with the 48-pin TSSOP footprint.

Selection Notes

Select this microcontroller when an 8-bit architecture with integrated analog-to-digital conversion is required. Consider the COP8CBE9 variant specifically for applications needing a low brownout reset threshold between 2.7V and 2.9V. Evaluate the 48-pin TSSOP package if space constraints favor surface-mount technology over PLCC or LLP options. Ensure the system design accommodates the single-supply voltage requirements and operating temperature limits defined in the electrical characteristics.

Part Context

The COP8CBE9 is part of the COP8CBE9/CCE9/CDE9 series, which shares identical core features but differs in brownout reset thresholds and temperature ranges. The CBE9 variant is distinguished by its low brownout voltage specification compared to the high brownout CCE9 or the no-brownout CDE9 models. All variants offer the same 8k Flash memory and peripheral set, allowing for flexible selection based on power management and environmental requirements.

Replacement Considerations

Direct substitutes include other members of the COP8CBE9/CCE9/CDE9 family with compatible packages. Verify that any replacement maintains the same 48-pin TSSOP form factor and electrical specifications. Check for equivalent brownout reset thresholds if power monitoring is critical to the application.
