COP8SAA716N9

Overview

The COP8SAA716N9 is an 8-bit CMOS One-Time Programmable (OTP) microcontroller from the COP8SA family, manufactured by Texas Instruments. It features 1 kilobyte of OTP program memory and 64 bytes of RAM. The device operates within a voltage range of 2.7V to 5.5V and supports instruction cycle times as fast as 1 microsecond at 10 MHz clock speeds. It is housed in a 16-pin DIP package and is rated for industrial temperature ranges including -40°C to +85°C.

Feature Summary

• Incorporates patented EMI reduction technology featuring low EMI clock circuitry, gradual turn-on output drivers, and internal current smoothing filters.
• Features a versatile instruction set with single-byte, single-cycle execution capabilities and true bit manipulation for efficient code density.
• Includes a multi-input wakeup logic system allowing multiple pins to trigger interrupts or wake the device from power-saving modes.
• Provides up to 12 high-current outputs capable of driving loads such as LEDs or small motors directly without external buffers.

Applications

• Low-cost embedded control systems requiring minimal electromagnetic interference.
• Battery-powered devices utilizing HALT and IDLE power-saving modes.
• Applications necessitating direct drive of indicators or simple actuators via high-current I/O ports.
• Systems requiring secure, non-volatile code storage with read/write protection.

Procurement Notes

Verify the specific ordering suffix 'N9' against the manufacturer's official datasheet to confirm the 16-pin DIP package and the -40°C to +85°C temperature rating. Ensure compatibility with existing development tools, as windowed versions are required for hardware emulation. Confirm that the OTP nature of the device aligns with production volume requirements, as programming is irreversible.

Selection Notes

Select this component when a cost-effective 8-bit solution with built-in EMI suppression is required. It serves as a pin-compatible replacement for older COP800 family devices in new designs. Consider the limited 1KB memory size for simpler control tasks. Evaluate the 16-pin package constraints against the necessary I/O count, noting that Port L availability may be reduced in smaller packages.

Part Context

This device belongs to the COP8SA family, which superseded the COP800 series. The family integrates advanced features like low EMI design and flexible oscillator options into a highly integrated CMOS architecture. The COP8SAA7 variant specifically denotes the 1KB OTP version, distinguishing it from ROM-based (COP8SAA5) or larger memory variants.

Replacement Considerations

The datasheet explicitly states that COP8SAx devices are instruction set and pin-compatible supersets of the COP800 Family devices. Designers should verify that the target application does not require features exclusive to newer families, as this is a legacy OTP controller.
