COP8CBE9HLQ9

Overview

The COP8CBE9HLQ9 is an 8-bit CMOS Flash microcontroller from the COP8CBE9 family, manufactured by Texas Instruments. It features 8k bytes of Flash program memory and 256 bytes of volatile RAM. The device includes a 10-bit Analog-to-Digital Converter with up to 16 channels, a USART with an on-chip baud generator, and two 16-bit timers. It operates within a supply voltage range of 2.7V to 5.5V and supports in-system programming via MICROWIRE/PLUS. The component is housed in a 44-pin Low Leadless Package (LLP) and is designed for applications requiring low electromagnetic interference.

Feature Summary

• Integrated Virtual EEPROM capability using Flash program memory for data retention.
• Patented EMI reduction technology including gradual turn-on output drivers and internal smoothing filters.
• Dual clock operation with a clock doubler allowing high-speed execution from lower frequency oscillators.
• True in-system emulation capability for software debugging using production devices.

Applications

• Embedded control systems requiring low electromagnetic interference.
• Applications needing in-system reprogrammable controllers with large memory.
• Devices utilizing analog signal processing via the integrated 10-bit A/D converter.
• Systems requiring serial communication through the built-in USART interface.

Procurement Notes

Verify the specific ordering suffix HLQ9 against official datasheets to confirm package type and temperature range. Ensure compatibility with development tools for the COP8 architecture. Confirm availability status as older components may have limited supply chains. Check for RoHS compliance documentation if required for your region. Validate pinout configurations for the 44-pin LLP package during PCB layout.

Selection Notes

Select this model when 8k Flash memory and 256 bytes RAM are sufficient for application logic. Choose the COP8CBE9 variant specifically for its low brownout reset threshold compared to other family members. Consider the LLP package for space-constrained designs requiring surface mount installation. Ensure the design accommodates the dual power supply requirements for digital and analog sections.

Part Context

This component belongs to the COP8CBE9/CCE9/CDE9 series of 8-bit microcontrollers. These devices share a common feature core but differ in brownout reset thresholds and operating temperature ranges. The COP8CBE9 is distinguished by its low voltage brownout detection, making it suitable for battery-powered or low-voltage applications within the specified commercial temperature range.

Replacement Considerations

Direct substitutes include other variants within the COP8CBE9/CCE9/CDE9 family, such as COP8CCE9 or COP8CDE9, provided the brownout voltage and temperature specifications align with system requirements. Verify that alternative packages like PLCC or TSSOP fit the mechanical constraints if pin compatibility is maintained.
