Overview
The COP8SGE728M8/63SN is an 8-bit CMOS OTP microcontroller from the COP8SG family, featuring 8k memory and a PLCC-44 package. It operates within a voltage range of 2.7V to 5.5V and supports temperatures from -40°C to +125°C. The device includes two analog comparators, a full-duplex USART, MICROWIRE/PLUS interface, three 16-bit timers, and an idle timer. It utilizes a modified Harvard architecture with a 0.67 μs instruction cycle time at 15 MHz.
Feature Summary
- Integrated EMI reduction circuitry including low radiated emissions clocking and gradual turn-on output drivers.
- Versatile I/O configuration allowing software-selectable TRI-STATE, push-pull, weak pull-up, and high impedance modes.
- Advanced power management capabilities with HALT and IDLE modes for significant current drain reduction.
Applications
- Complex embedded control systems requiring larger program memory
- Applications necessitating integrated analog comparator functionality
- Systems utilizing full-duplex serial communication protocols
Procurement Notes
Verify component authenticity through authorized channels as this part may be subject to obsolescence. Confirm that the specific ordering suffix matches the required package and temperature grade. Ensure compatibility with existing development tools for OTP programming. Review datasheet specifications regarding moisture sensitivity levels prior to assembly.
Selection Notes
Select this model when 8k OTP capacity meets application requirements alongside integrated analog features. Consider the PLCC-44 package constraints for board layout. Evaluate the need for the specific COP8 core instruction set efficiency. Verify that the operating voltage range aligns with system power supply rails.
Part Context
This component belongs to the COP8SG family of 8-bit microcontrollers designed for cost-effective, high-performance applications. The 'E' designation indicates 8k memory size, while '7' specifies OTP EPROM technology. The family shares architectural similarities with ROM-based variants but offers field-programmability for production flexibility.
Replacement Considerations
COP8SGR7 devices are form-fit-function compatible OTP versions within the same family. Windowed Q3 packages are available for development purposes using standard COP8 tools.
