COP8SAA716M8

Overview

The COP8SAA716M8 is an 8-bit CMOS One-Time Programmable (OTP) microcontroller from the COP8SA family, manufactured by Texas Instruments. It features 1k bytes of OTP program memory and 64 bytes of RAM. The device operates within a voltage range of 2.7V to 5.5V and supports an industrial temperature range of -40°C to +85°C. It utilizes a modified Harvard architecture with a 1 µs instruction cycle time at 10 MHz clock speeds. Key peripherals include a 16-bit timer/counter with PWM output, MICROWIRE/PLUS serial interface, and Multi-Input Wakeup logic.

Feature Summary

• Integrated EMI reduction technology featuring low radiated emissions, gradual turn-on output drivers, and internal current smoothing filters.
• Versatile instruction set optimized for code efficiency, supporting single-byte single-cycle execution and true bit manipulation.
• Flexible I/O configuration allowing software-selectable TRI-STATE, push-pull, weak pull-up, or high impedance modes.
• Multi-sourced interrupt capability including external interrupts, idle timer, and multi-input wakeup pins.

Applications

• Low-cost embedded control systems requiring full featured controller capabilities
• Applications necessitating low electromagnetic interference (EMI) performance
• Battery-powered devices utilizing power-saving HALT and IDLE modes
• Industrial controllers operating in extended temperature environments

Procurement Notes

Verify component authenticity through authorized distributors as this part may be subject to obsolescence. Confirm specific ordering suffixes match required package types and temperature grades. Ensure development tools are compatible with the COP8SA family architecture before procurement. Check for moisture sensitivity levels and storage requirements prior to assembly.

Selection Notes

Select this component when a cost-effective 8-bit solution with OTP flexibility is required. Consider the COP8SA family for its pin compatibility with older COP800 devices. Evaluate memory requirements against the 1k OTP capacity. Ensure system design accommodates the specific I/O port configurations and available packages such as DIP or SOIC.

Part Context

This microcontroller belongs to the COP8SA family, which serves as a superserset replacement for the legacy COP800 family in new designs. The family shares instruction set compatibility while offering enhanced features like reduced EMI and smaller packaging options. It targets applications demanding high integration and low component counts.

Replacement Considerations

COP8SAA716M9 is the commercial temperature variant (0°C to +70°C). COP8SAC7 series offers higher memory capacities (4k OTP). Verify pinout compatibility if substituting with other COP8SA members.
