COP8SAC744J3

Overview

The COP8SAC744J3 is a 4k EPROM-based 8-bit microcontroller from the COP8SA family, manufactured by Texas Instruments. It features an 8-bit CPU core with 128 bytes of RAM and supports up to 40 I/O pins. The device operates within a temperature range of 0°C to +70°C and utilizes a 44-pin PLCC package.

Feature Summary

• Incorporates low EMI circuitry including gradual turn-on output drivers and internal current smoothing filters.
• Features a versatile instruction set optimized for code efficiency with single-byte, single-cycle execution capabilities.
• Includes a multi-input wakeup logic system supporting optional interrupts on multiple pins.

Applications

• Low-cost embedded controller applications requiring full feature sets
• Systems necessitating low electromagnetic interference (EMI) performance
• Designs utilizing Power-On Reset (POR) functionality

Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence. Confirm that the specific ordering suffix matches the required package type and memory configuration. Ensure compatibility with existing development tools if windowed versions are needed for programming.

Selection Notes

Select this component when a 4k EPROM capacity and 44-pin PLCC packaging are required. It serves as a replacement for older COP800 family devices in new designs. Consider the 0°C to +70°C operating range and ensure the application does not require extended industrial or automotive temperature ratings.

Part Context

This device belongs to the COP8SA family of 8-bit CMOS microcontrollers. It is pin-compatible with the COP800 family but offers enhanced features such as low EMI design and advanced interrupt handling. The family includes ROM, OTP, and EPROM variants across various package sizes.
