COP8SAB720N9

Overview

The COP8SAB720N9 is a 2k OTP microcontroller from the COP8SA family, featuring an 8-bit architecture with 128 bytes of RAM and 16 I/O pins. It operates on a single supply voltage ranging from 2.7V to 5.5V and supports instruction cycle times as fast as 1µs at 10MHz clock speeds. The device includes a 16-bit timer/counter, MICROWIRE/PLUS serial interface, and power-saving HALT/IDLE modes.

Feature Summary

• Integrated low EMI circuitry including gradual turn-on output drivers and internal current smoothing filters to reduce radiated emissions.
• Modified Harvard architecture allowing direct access to data tables stored in program memory for efficient code execution.
• Versatile instruction set optimized for code efficiency, enabling complex operations within single-byte instructions.

Applications

• Low-cost embedded control systems requiring small packaging
• Battery-powered devices utilizing power-saving HALT and IDLE modes
• Applications needing robust electromagnetic interference reduction

Procurement Notes

Verify the specific ordering suffix '20N9' against the manufacturer's official documentation to confirm package type (DIP-20) and temperature range. Ensure compatibility with existing development tools such as MetaLink systems for programming and debugging this OTP variant.

Selection Notes

Select this component when a cost-effective 8-bit solution with 2k program memory is required. It serves as a pin-compatible replacement for older COP800 family devices. Consider its low current drain and high current output capabilities for driving external loads directly without additional buffering components.

Part Context
