CR16MAS9VJE9/NOPB

Overview

The CR16MAS9VJE9/NOPB is a 16-bit microcontroller from Texas Instruments, part of the CR16B series. It features a RISC core with 64 kB of Flash program memory and 3 kB of data RAM. The device operates at a maximum clock frequency of 16 MHz and provides 56 I/O pins. It is housed in an 80-pin PQFP package and supports serial interfaces. The component is designed for industrial temperature ranges, operating between -40°C and +70°C or +85°C depending on specific variant documentation.

Feature Summary

• Integrates a 16-bit RISC architecture for efficient processing
• Includes non-volatile Flash memory for program storage
• Provides extensive general-purpose input/output capabilities
• Supports serial communication interfaces

Applications

• Industrial control systems requiring robust 16-bit processing
• Embedded applications utilizing serial communication protocols
• General-purpose microcontroller tasks within specified thermal limits

Procurement Notes

Verify the current lifecycle status before procurement, as availability may be limited. Confirm the exact operating temperature range required for your application against the specific datasheet revision. Ensure compatibility with the 80-pin PQFP footprint during PCB design. Check for any specific moisture sensitivity levels if reflow soldering is planned. Validate that the 16 MHz clock speed meets system timing requirements.

Selection Notes

Select this component when a 16-bit RISC architecture is preferred over 8-bit alternatives for complex logic. Consider the 64 kB Flash capacity for larger firmware requirements. Evaluate the 56 I/O count against interface needs to minimize external multiplexing. Compare power consumption characteristics against other CR16 family members if battery operation is critical.

Part Context

This microcontroller belongs to the CR16B family, which targets cost-sensitive embedded markets. It shares architectural similarities with other 16-bit MCUs but offers specific pin counts and memory configurations tailored for mid-range applications. The NOPB suffix indicates lead-free packaging compliant with RoHS standards.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Review the broader CR16B family for pin-compatible or functionally similar devices. Verify memory size and I/O counts when selecting alternative parts.
