Overview
The COP8SGE744V8/NOPB is an 8-bit CMOS OTP microcontroller from the COP8SG family, featuring 8k OTP EPROM and 256 bytes of RAM. It operates within a 2.7V to 5.5V supply range and supports industrial temperature ranges of -40°C to +85°C or -40°C to +125°C. The device integrates two analog comparators, a full-duplex USART, MICROWIRE/PLUS serial interface, three 16-bit timers, and multi-input wakeup logic. It utilizes a modified Harvard architecture with a 0.67 μs instruction cycle at 15 MHz and offers low EMI design features.
Feature Summary
- Integrated dual analog comparators for signal processing without external components
- EMI reduction technology including gradual turn-on output drivers and internal ICC smoothing filters
- Versatile I/O configuration supporting high current outputs, weak pull-ups, and Schmitt trigger inputs
- Multi-function timer system with PWM, event counter, and input capture capabilities
Applications
- Complex embedded control systems requiring larger memory capacity
- Applications demanding low electromagnetic interference (EMI) emissions
- Industrial monitoring utilizing integrated analog comparators
- Serial communication interfaces using USART or MICROWIRE/PLUS protocols
Procurement Notes
Verify the specific suffix 'NOPB' against official Texas Instruments documentation to confirm lead-free status and RoHS compliance. Confirm the package type matches the required 44-pin form factor. Ensure the OTP programming requirements align with available development tools. Check current production status as legacy families may have limited availability.
Selection Notes
Select this component when a cost-effective 8-bit solution with OTP flexibility is needed. Choose over ROM versions if field updates are not required but manufacturing flexibility is desired. Consider the COP8SGx7 series for its compatibility with COP8SGx5 ROM devices while offering programmable memory. Evaluate power consumption in HALT and IDLE modes for battery-sensitive designs.
Part Context
This part belongs to the COP8SG family of 8-bit microcontrollers designed for complex applications. It shares architectural similarities with other members like COP8SGR7 but differs in memory size and package options. The family emphasizes code efficiency through a unique instruction set and modified Harvard architecture, allowing direct access to data tables stored in program memory.
Replacement Considerations
COP8SGE744V8 is functionally compatible with other COP8SGE7 variants in different packages. Verify pinout compatibility when substituting between PLCC, LQFP, or WQFN packages. No direct cross-family replacements exist; migration requires software adaptation due to specific peripheral configurations.
