Overview
The COP8SAC728M8/NOPB is an 8-bit CMOS microcontroller from the COP8SA family, featuring 4k bytes of OTP memory and 128 bytes of RAM. It operates within a voltage range of 2.7V to 5.5V and supports temperatures from -40°C to +85°C. The device utilizes a 28-pin SOIC package and includes a 16-bit timer with PWM output, MICROWIRE/PLUS serial interface, and Multi-Input Wakeup logic.
Feature Summary
- Integrated EMI reduction technology including low EMI clock circuitry and gradual turn-on output drivers.
- 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.
- Supports multiple oscillator options including internal R/C, external crystal, and external clock sources.
Applications
- Low-cost embedded control systems requiring full featured controller capabilities
- Applications necessitating low electromagnetic interference (EMI) emissions
- Battery-powered devices utilizing power saving HALT and IDLE modes
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm pin compatibility and temperature ratings. Ensure that the NOPB designation aligns with current environmental compliance requirements for the intended deployment region. Cross-reference the datasheet revision history to validate electrical characteristics prior to finalizing procurement specifications.
Selection Notes
Select this component when a cost-effective 8-bit solution with OTP programmability is required. Consider the COP8SA family for its high pin efficiency and integrated peripherals such as the 16-bit timer and MICROWIRE interface. Evaluate the package constraints to ensure the 28-pin SOIC form factor fits the board layout while providing sufficient I/O lines for the application.
Part Context
This device belongs to the COP8SA family, which serves as a superset of the older COP800 architecture. It offers enhanced features like low EMI operation and very small packaging options compared to legacy counterparts. The family is designed to replace older ROM-based controllers in new designs while maintaining backward compatibility where possible.
