Overview
The COP8SGR728N8/NOPB is an 8-bit CMOS OTP microcontroller from the COP8SG family, featuring 32k OTP EPROM and 512 bytes of RAM. It operates within a 4.5V to 5.5V supply range at temperatures up to +125°C. The device integrates three 16-bit timers, a full-duplex USART, MICROWIRE/PLUS interface, and two analog comparators. It utilizes a 44-pin PLCC package with 40 I/O pins.
Feature Summary
- Integrates two analog comparators for signal processing without external components
- Features low radiated emissions through patented EMI reduction circuitry
- Includes multi-input wakeup logic with optional interrupts for power management
- Supports versatile instruction sets with single-byte single-cycle execution
Applications
- Complex embedded control systems requiring larger memory
- Applications demanding low electromagnetic interference (EMI)
- Systems utilizing full-duplex serial communication protocols
- Industrial controllers operating in high-temperature environments
Procurement Notes
Verify that the specific suffix '28' aligns with the manufacturer's pinout or variant definitions, as standard datasheets list base part numbers like COP8SGR7. Confirm the 44-pin PLCC package availability matches the required footprint. Ensure the OTP programming requirements are compatible with existing development tools before procurement.
Selection Notes
Select this component when 32k program memory and 512 bytes of RAM are necessary for complex applications. Choose this model over ROM versions if field programmability or prototyping flexibility is required. Consider the integrated analog comparators and USART capabilities to reduce external component count in the design.
Part Context
This device belongs to the COP8SG family of 8-bit microcontrollers designed for cost-effective, high-performance applications. The family combines ROM and OTP variants with advanced peripherals like timers and serial interfaces. The COP8SGR7 specifically denotes the 32k OTP version, offering form-fit-function compatibility with its ROM counterpart.
Replacement Considerations
COP8SGR5/NOPB serves as a direct replacement if only 32k ROM is sufficient. For lower memory requirements, COP8SGE7/NOPB provides 8k OTP. Verify that the target application does not require the extended -40°C to +85°C temperature range if the +125°C variant is strictly necessary.
