Overview
The COP8TAC9EMW8/NOPB is an 8-bit CMOS Flash microcontroller from the COP8TAx9 family, manufactured by Texas Instruments. It features 4 KB of Flash program memory and 128 bytes of RAM. The device operates within a supply voltage range of 2.25V to 2.75V and supports an internal RC oscillator at 10 MHz or an external crystal oscillator up to 15 MHz. It is housed in a 28-pin SOIC package and functions across a temperature range of -40°C to +85°C.
Feature Summary
- Includes 4 KB of in-system reprogrammable Flash memory with security features and high endurance.
- Integrates MICROWIRE/PLUS and ACCESS.Bus synchronous serial interfaces for communication.
- Features low electromagnetic interference (EMI) design with quiet clock circuitry and output drivers.
- Provides true in-system emulation capabilities for software debugging on production boards.
Applications
- In-system programmable controller applications requiring moderate memory
- Low EMI embedded control designs
- Development and pre-production phases using final production devices
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and temperature range. Ensure code compatibility if migrating from Masked ROM variants, as Boot ROM function calls may differ between Flash and ROM versions.
Selection Notes
Select this component for applications needing in-system reprogrammability and low power consumption. Consider the 2.25V–2.75V operating voltage constraint. Verify that the required I/O count fits within the 28-pin package limitations and that the 10 MHz internal RC or 15 MHz crystal timing meets system requirements.
Part Context
This part belongs to the COP8TAx9 series of 8-bit CMOS Flash microcontrollers. It shares architectural similarities with the COP8TAB9 but offers double the program memory capacity. The COP8 family utilizes a modified Harvard architecture and a unique instruction set optimized for code efficiency and single-cycle execution.
Replacement Considerations
COP8TAB9EMW8/NOPB: Offers identical functionality with 2 KB Flash memory instead of 4 KB. Ensure application code does not exceed 2 KB when substituting.
