COP8SAB720M8

Overview

The COP8SAB720M8 is an 8-bit CMOS microcontroller from the COP8SA family, featuring 2k bytes of One-Time Programmable (OTP) EPROM and 128 bytes of RAM. It utilizes a modified Harvard architecture with a single-cycle instruction cycle time of 1 µs at 10 MHz CKI. The device operates within a voltage range of 2.7V to 5.5V and supports temperatures from -40°C to +85°C. Key peripherals include a 16-bit timer/counter, MICROWIRE/PLUS serial interface, and Multi-Input Wakeup logic.

Feature Summary

• Low electromagnetic interference design utilizing patented EMI reduction circuitry for quiet operation.
• Versatile instruction set optimized for code efficiency with single-byte, single-cycle execution capabilities.
• Flexible I/O configuration allowing software-selectable TRI-STATE, push-pull, or weak pull-up modes.
• Integrated power management features including HALT and IDLE modes with low current drain.

Applications

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

Procurement Notes

Verify the specific suffix M8 confirms the -40°C to +85°C temperature grade and 20-pin package type against the manufacturer's ordering guide. Confirm that the OTP variant matches the required memory capacity and security settings for the application. Check for end-of-life status as this component series may be discontinued.

Selection Notes

Select this part when a balance of moderate program memory and high pin efficiency is required. The COP8SAB720M8 offers a cost-effective solution compared to ROM-based equivalents while maintaining full form-fit-function compatibility with the COP800 family. Ensure the design accommodates the OTP programming process if field reprogramming is not needed.

Part Context

This component belongs to the COP8SA family, which serves as a superserset replacement for the legacy COP800 devices. The family integrates advanced features like low EMI and Power-On Reset into a highly compact footprint. The COP8SAB720M8 specifically provides 2k OTP memory in a 20-pin package, bridging the gap between lower and higher density variants.
