COP8CCE9HLQ9

Overview

The COP8CCE9HLQ9 is an 8-bit CMOS Flash microcontroller from the COP8CBE9/CCE9/CDE9 family. It features 8k bytes of Flash program memory, 256 bytes of volatile RAM, and a 10-bit Analog-to-Digital Converter supporting up to 16 channels. The device includes Virtual EEPROM functionality via Flash emulation, a USART with an on-chip baud generator, and two 16-bit timers. It operates within a supply voltage range of 4.5V to 5.5V for industrial temperatures (-40°C to +125°C) and 2.7V to 5.5V for commercial temperatures (0°C to +70°C). Key hardware features include Brownout Reset, high-current I/Os, and EMI reduction circuitry.

Feature Summary

• Virtual EEPROM capability allows variable non-volatile data storage by emulating EEPROM using Flash program memory blocks.
• Integrated EMI reduction technology utilizes low EMI clock circuits, gradual turn-on output drivers, and internal smoothing filters to minimize radiated emissions.
• Dual clock operation supports high-speed processing and low-power HALT/IDLE modes, featuring a clock doubler for enhanced performance.
• High-current I/O ports provide sufficient drive strength for direct connection to peripherals such as LEDs, motors, and speakers.

Applications

• In-system reprogrammable controllers requiring large memory capacity
• Embedded control designs sensitive to electromagnetic interference
• Applications necessitating virtual EEPROM for data retention without external components

Procurement Notes

Verify the specific package type and temperature grade against the ordering suffix, as the datasheet lists multiple variants (e.g., LLP, PLCC, TSSOP) and ranges. Confirm that the 'HLQ9' designation aligns with the manufacturer's current part numbering scheme for the 44-pin LLP package and extended temperature range. Cross-reference the component with official Texas Instruments or National Semiconductor documentation to ensure authenticity and correct revision status before procurement.

Selection Notes

Select this microcontroller when system design demands integrated analog conversion, serial communication, and in-system programmability within a single chip. The COP8CCE9 variant is appropriate for applications requiring a higher Brownout reset threshold compared to the CBE9 series. Consider the modified Harvard architecture and code-efficient instruction set for optimizing program memory usage in cost-sensitive embedded systems.

Part Context

The COP8CCE9HLQ9 belongs to the COP8CBE9/CCE9/CDE9 series of 8-bit CMOS Flash microcontrollers. This family is characterized by its integration of advanced features like Virtual EEPROM and high-speed timers alongside standard microcontroller functions. The devices are designed for versatility, supporting development, pre-production, and volume production using common software and hardware tools across the series.
