COP8SAA716M7

Overview

The COP8SAA716M7 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 +125°C. It utilizes a 16-pin DIP package and includes an on-chip R/C oscillator, Power-On Reset, and MICROWIRE/PLUS serial interface.

Feature Summary

• Integrated low electromagnetic interference (EMI) design with gradual turn-on output drivers
• Versatile instruction set optimized for code efficiency and single-cycle execution
• Configurable I/O ports supporting push-pull, tri-state, and weak pull-up modes
• Built-in multi-input wakeup logic and power-saving HALT/IDLE modes

Applications

• Low-cost embedded control systems requiring EMI reduction
• Battery-powered devices utilizing low current drain modes
• Industrial controllers operating in extended temperature environments
• Applications requiring simple serial communication via MICROWIRE/PLUS

Procurement Notes

Verify the specific suffix 'M7' confirms the -40°C to +125°C temperature grade and 16-pin DIP package configuration. Confirm that the OTP version matches the required memory size and pinout compatibility with existing designs. Check for end-of-life status or obsolescence notices as this component belongs to an older generation family.

Selection Notes

Select this component when a cost-effective 8-bit solution with built-in EMI suppression is required. It serves as a direct replacement for COP800 family devices in new designs. Ensure the application does not require erasable memory, as this is an OTP variant. Verify that the 1k word program space and 64-byte RAM are sufficient for the intended firmware complexity.

Part Context

This part belongs to the COP8SA family, which expands upon the legacy COP800 architecture. The family offers various memory sizes and packaging options to suit different integration needs. The COP8SAA7 series specifically denotes the 1k OTP variant, providing a balance between functionality and board space efficiency for compact electronic designs.
