COP8SAC720N9

Overview

The COP8SAC720N9 is an 8-bit CMOS microcontroller from the COP8SA family, featuring 4k bytes of OTP EPROM program memory and 128 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 a Power-On Reset (POR) circuit. It offers up to 16 I/O pins in a 20-pin DIP package and incorporates low EMI design features.

Feature Summary

• Low electromagnetic interference (EMI) design utilizing gradual turn-on output drivers and internal smoothing filters.
• Versatile instruction set optimized for code efficiency with single-byte, single-cycle execution capabilities.
• Integrated peripheral support including a 16-bit timer/counter with PWM output and MICROWIRE/PLUS serial interface.
• User-selectable configuration options for clock sources, watchdog timer, and power-on reset logic.

Applications

• Battery-powered consumer electronics requiring low current drain
• Industrial control systems needing robust EMI performance
• Cost-sensitive embedded applications utilizing OTP programming

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm temperature range and package type. Confirm availability status as legacy components may be discontinued or subject to limited supply constraints. Ensure compatibility with existing development tools for COP8SA family devices before procurement.

Selection Notes

Select this component when a cost-effective 8-bit solution with OTP flexibility is required. Consider the 20-pin DIP package for through-hole mounting requirements. Evaluate the 4k memory size against application code complexity. Verify that the 16 available I/O pins meet system interface needs without additional multiplexing.

Part Context

This part belongs to the COP8SA family, which serves as a pin-compatible superset of the older COP800 family. The COP8SA series introduces enhanced features such as lower EMI emissions and improved packaging options while maintaining backward compatibility with established COP8 software and hardware development environments.
