COP8SAA716M9

Overview

The COP8SAA716M9 is an 8-bit CMOS microcontroller from the COP8SA family, featuring 1k bytes of OTP EPROM and 64 bytes of RAM. It utilizes a modified Harvard architecture with a 1 µs instruction cycle time at 10 MHz CKI. The device supports single-supply operation between 2.7V and 5.5V and includes an on-chip R/C oscillator. Key peripherals include a 16-bit timer/counter with PWM output, MICROWIRE/PLUS serial interface, and Multi-Input Wakeup logic. It is housed in a 16-pin PLCC package.

Feature Summary

• Low EMI design incorporating gradual turn-on output drivers and internal current smoothing filters to reduce radiated emissions.
• Versatile I/O configuration allowing software-selectable TRI-STATE, push-pull, weak pull-up, or high impedance modes.
• Integrated power management features including user-selectable Power-On Reset, WATCHDOG timer, and low-power HALT/IDLE modes.

Applications

• Battery-powered consumer electronics requiring low standby current
• Industrial control systems utilizing MICROWIRE/PLUS communication
• Appliances needing robust EMI performance and simple I/O interfacing

Procurement Notes

Verify the specific ordering suffix M9 corresponds to the 0°C to +70°C temperature range as defined in the official National Semiconductor ordering guide. Confirm that the windowed PLCC package is suitable for your development tool requirements, as this variant supports hardware debugging. Ensure compatibility with existing COP800 family designs if used as a direct replacement.

Selection Notes

Select this component when a cost-effective 8-bit solution with OTP flexibility is required. It serves as a pin-compatible superset to the COP800 family, facilitating migration. Consider the 16-pin PLCC package for applications demanding moderate I/O counts within a compact footprint. Evaluate the internal R/C oscillator accuracy against system timing requirements.

Part Context

This device belongs to the COP8SA family, which expands upon the legacy COP800 architecture. It offers enhanced integration with reduced packaging options compared to earlier generations. The family emphasizes code efficiency through a unique instruction set optimized for small program memory spaces, targeting low-cost embedded control applications.
