- Embedded applications needing reliable Flash-based code execution
Procurement Notes
Verify the specific suffix configuration against official datasheets to ensure compatibility with existing designs. Confirm that the PLCC-44 package dimensions match the target PCB footprint. Check for moisture sensitivity level requirements during assembly. Ensure the operating voltage range aligns with the system power supply. Validate that the end-of-life status does not impact long-term production needs.
Selection Notes
Select this component when an 8-bit architecture with substantial Flash memory is required. Consider the PLCC-44 package if surface-mount leaded chip carriers are preferred. Evaluate the 10 MHz clock speed against processing demands. Verify that the available I/O count meets interface requirements. Assess the absence of an ADC as it may necessitate external conversion components.
Part Context
This part belongs to the COP8SCR9 family of 8-bit CMOS Flash microcontrollers. These devices are designed for cost-sensitive applications requiring moderate performance. The COP8 architecture offers efficient instruction execution. Texas Instruments continues to support legacy components for maintenance purposes.
Replacement Considerations
Consult official substitution guides for compatible parts. Verify pinout and electrical specifications before replacing. Ensure software compatibility with alternative controllers.
