COP8SAA720N8

Overview

The COP8SAA720N8 is an 8-bit CMOS microcontroller from the COP8SA family, featuring 1k bytes of OTP program memory and 64 bytes of RAM. It utilizes a 20-pin DIP package and operates within a temperature range of -40°C to +85°C. The device supports a 10 MHz clock input with a 1 µs instruction cycle and includes a Power-On Reset circuit. Key peripherals consist of a 16-bit timer/counter with PWM output, MICROWIRE/PLUS serial interface, and Multi-Input Wakeup logic.

Feature Summary

• Integrated EMI reduction technology including low EMI clocking and gradual turn-on output drivers
• Versatile software-selectable I/O configurations supporting push-pull, tri-state, and weak pull-up modes
• Modified Harvard architecture enabling direct data table access from program memory
• User-selectable oscillator options including internal R/C, crystal/resonator, and external sources

Applications

• Low-cost embedded control systems requiring full featured controller capabilities
• Applications necessitating low electromagnetic interference (EMI) emissions
• Battery-powered devices utilizing HALT and IDLE power saving modes
• Systems requiring robust reset mechanisms via on-chip Power-On Reset

Procurement Notes

Verify the specific ordering suffix N8 confirms the 20-pin DIP package and the -40°C to +85°C industrial temperature range. Confirm that the 'A' variant designation corresponds to the 1k OTP memory configuration as defined in the official datasheet. Ensure compatibility with existing development tools for the COP8SA family before procurement.

Selection Notes

Select this component when a cost-effective 8-bit solution with OTP flexibility is required. It serves as a pin-compatible replacement for older COP800 family devices in new designs. Consider the 20-pin form factor for space-constrained applications needing moderate I/O counts. Evaluate the internal R/C oscillator accuracy if precise timing is critical without external components.

Part Context

This part belongs to the COP8SA family, which expands upon the COP800 architecture. The family offers ROM and OTP variants across various memory sizes and packages. The COP8SAA7 series specifically targets applications needing 1k to 4k memory with advanced features like low EMI and small packaging options such as CSP and DIP.

Replacement Considerations

COP8SAA720M8: Identical electrical specifications and memory but housed in a 20-pin SOIC package instead of DIP.
