COP8TAB9EMW8

Overview

The COP8TAB9EMW8 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 2.25 V to 2.75 V and supports a maximum clock frequency of 15 MHz. It is housed in a 28-pin SOIC wide package and functions across a temperature range of -40°C to +85°C.

Feature Summary

Incorporates patented EMI reduction technology including low radiated emissions circuitry for quiet design operation.
Supports true in-system programming and emulation via MICROWIRE/PLUS interface without requiring external programmers.
Features high current I/O capability with 10 mA drive strength at low voltage levels.

Applications

Embedded control systems requiring low electromagnetic interference.
Applications necessitating in-system reprogrammability and debugging on final production boards.
Battery-powered devices utilizing low voltage operation and power save modes.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as datasheet indicates potential variations. Check for obsolescence notices as this series may be discontinued. Ensure development tools are compatible with the specific COP8TAx9 feature set before procurement.

Selection Notes

Select this model when 4 kB of Flash memory is required alongside 128 bytes of RAM. Choose the 28-pin SOIC package for surface mount assembly needs. Ensure the application environment stays within the specified -40°C to +85°C operating temperature range. Verify that the 2.25V to 2.75V supply voltage aligns with system power constraints.

Part Context

This component belongs to the COP8TAx9 series of 8-bit microcontrollers. It shares architectural similarities with the COP8TAB5 masked ROM variant but includes Boot ROM and Flash capabilities. The device utilizes the modified Harvard architecture typical of the COP8 family, allowing direct access to data tables stored in program memory.
