Overview
The COP8CBR9IMT8/NOPB is an 8-bit CMOS Flash microcontroller from the COP8CBR9 family, manufactured by Texas Instruments. It features 32 kbytes of Flash program memory and 1 kbyte of volatile RAM. The device includes a 10-bit Analog-to-Digital Converter supporting up to 16 channels, two USART modules, and three timers. Operating voltage ranges from 2.7V to 5.5V with a maximum clock frequency of 20 MHz. It utilizes a TSSOP-48 package and supports in-system programming via MICROWIRE/PLUS.
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 high-speed and low-speed oscillators for power saving modes
- True in-system emulation and real-time debugging support
Applications
- Embedded control systems requiring large program memory
- Applications needing analog signal processing with integrated ADC
- Low electromagnetic interference designs
- In-system programmable controller applications
Procurement Notes
Verify the complete part number including the /NOPB suffix to ensure lead-free compliance and specific package configuration. Confirm the manufacturer source as Texas Instruments or authorized distributors. Check the datasheet revision history for any updates to electrical characteristics or pin assignments before finalizing procurement specifications.
Selection Notes
Select this component when an 8-bit architecture with substantial Flash memory and virtual EEPROM functionality is required. Ensure the application operates within the 2.7V to 5.5V supply range. Verify that the TSSOP-48 package fits the board layout constraints. Consider the dual-clock feature if power management across different operational states is a priority.
Part Context
This device belongs to the COP8CBR9 series, which shares architectural similarities with the COP8CCR9 and COP8CDR9 models. The primary distinction lies in the Brownout Reset voltage thresholds and operating temperature ranges. The COP8CBR9 specifically supports a lower voltage threshold compared to the CCR9 variant.

FAQ
How does the Virtual EEPROM function work?
The Virtual EEPROM feature emulates variable amounts of EEPROM by allowing the user to initialize nonvolatile variables from Flash Memory and occasionally restore these variables back to the Flash Memory.
What is the maximum instruction cycle time at 2.7V?
At operating voltages between 2.7V and 4.5V, the maximum instruction cycle time is 1.5 microseconds.
Does the device support in-system programming?
Yes, the device supports true in-system programming of Flash memory through the MICROWIRE/PLUS serial interface or custom boot ROM routines.
