COP8CBE9IMT9/NOPB

Overview

The COP8CBE9IMT9/NOPB 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 at temperatures between 0°C and +70°C. The component is housed in a 48-pin TSSOP package.

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
• Dual clock operation with HALT/IDLE power save modes and a clock doubler for high-speed performance
• True in-system emulation and programming via MICROWIRE/PLUS serial interface

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and temperature range. Ensure compatibility with existing development tools and software libraries designed for the COP8CBE9 family. Confirm that the 48-pin TSSOP footprint matches the target PCB design requirements before procurement.

Selection Notes

Select this component when an 8-bit architecture with integrated analog conversion and serial communication interfaces is required. Consider the 8k Flash capacity and 256-byte RAM limits for application complexity. Evaluate the need for Brownout Reset functionality and the specific operating temperature range of 0°C to +70°C against system environmental conditions.

Part Context

This part belongs to the COP8CBE9/CCE9/CDE9 series of 8-bit CMOS Flash microcontrollers. These devices are based on the COP8 Feature core and are designed for highly integrated applications. The series offers various memory sizes and package options, supporting both standard and extended temperature ranges depending on the specific variant selected.

Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the COP8CBE9/CCE9/CDE9 family. Verify if other variants offer different Brownout thresholds or temperature ranges suitable for the specific application environment without requiring board redesign.

FAQ

What is the maximum clock frequency supported by the COP8CBE9IMT9/NOPB?

The device supports a primary oscillator operating at high speed up to 10 MHz, which can be doubled to 20 MHz using the internal clock doubler.

How does the Virtual EEPROM feature function?

Virtual EEPROM emulates variable amounts of EEPROM by allowing the user to initialize nonvolatile variables from Flash Memory and occasionally restore these variables back to Flash Memory using routines in the boot ROM.

What I/O configuration options are available for the ports?

Each individual I/O pin can be independently configured as an output (low or high), input with high impedance, or input with a weak pull-up device under program control.
