Overview
The COP8SAA720M9 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 0°C to +70°C. The device supports a single supply voltage of 2.7V to 5.5V and includes an on-chip R/C oscillator with selectable clock modes. Key peripherals include a 16-bit timer/counter with PWM output, MICROWIRE/PLUS serial interface, and Multi-Input Wakeup logic.
Feature Summary
- Low electromagnetic interference design utilizing gradual turn-on output drivers and internal current smoothing filters.
- 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 multi-sourced wakeup interrupts.
Applications
- Battery-powered consumer electronics requiring low standby current
- Industrial control systems needing robust EMI performance
- Simple embedded interfaces using MICROWIRE/PLUS communication
Procurement Notes
Verify the specific ordering suffix M9 corresponds to the required 0°C to +70°C commercial temperature grade. Confirm that the 20-pin DIP package meets the mechanical constraints of the target PCB layout. Ensure development tools support the COP8SA architecture for programming the OTP memory space.
Selection Notes
Select this component when a cost-effective 8-bit solution with OTP flexibility is required. It serves as a direct pin-compatible replacement for older COP800 devices in new designs. Consider the 20-pin form factor for applications where board space is limited but through-hole mounting is preferred over surface mount options.
Part Context
This part belongs to the COP8SA family, which expands upon the legacy COP800 architecture. The family integrates advanced features such as low EMI circuitry and high-current outputs while maintaining backward compatibility with existing instruction sets. It targets applications demanding full-featured controller capabilities at a minimal system cost.
