COP8SGR744V8/NOPB

Overview

The COP8SGR744V8/NOPB is an 8-bit CMOS microcontroller from the COP8SG family, featuring 32k OTP EPROM and 512 bytes of RAM. It integrates a full-duplex USART, two analog comparators, three 16-bit timers, and MICROWIRE/PLUS serial interface. The device operates on a 2.7V to 5.5V supply with instruction cycle times as fast as 0.67 μs at 15 MHz. It includes low EMI features, multi-input wakeup logic, and user-selectable clock options.

Feature Summary

• Integrated full-duplex USART and MICROWIRE/PLUS serial interface for communication
• Two analog comparators with high input impedance and programmable enable
• Three 16-bit timers supporting PWM, external event counting, and input capture
• Low electromagnetic interference design with gradual turn-on output drivers

Applications

• Complex embedded control systems requiring larger memory capacity
• Applications necessitating analog signal processing via integrated comparators
• Systems utilizing asynchronous serial communication protocols
• Devices requiring precise timing control through multiple hardware timers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature range compatibility. Ensure that the NOPB designation aligns with RoHS compliance requirements for your target market. Confirm availability status as legacy components may have limited production runs or end-of-life implications.

Selection Notes

Select this component when system design demands high I/O pin efficiency combined with substantial program memory. The modified Harvard architecture supports efficient data table access directly from program memory. Consider the OTP nature for production volumes where ROM customization is unnecessary but flexibility during development is required.

Part Context

This part belongs to the COP8SG family of 8-bit microcontrollers designed for cost-sensitive applications. It serves as the OTP version compatible with the COP8SGR5 ROM counterpart. The family emphasizes low power consumption and reduced board space through high integration of peripherals within standard packages like PLCC.

Replacement Considerations

COP8SGR544V8 is the ROM-based equivalent within the same family. COP8SGE744V8 offers lower memory capacity (8k) but maintains functional compatibility. Verify pinout and software compatibility before substituting, as memory size differences may impact code execution.
