Overview
The CR16MCS9VJE7 is a member of the 16-bit CAN-enabled CompactRISC Microcontroller family manufactured by National Semiconductor. It utilizes the CR16B CPU core and operates at a maximum clock frequency of 16 MHz. The device features an integrated Analog-to-Digital Converter (ADC) and provides 56 I/O lines within an 80-pin Plastic Quad Flat Package (QFP). It supports an external data bus width and functions within a temperature range of -40 °C to 125 °C.
Feature Summary
- Integrates Controller Area Network (CAN) communication capabilities for embedded systems.
- Includes built-in Analog-to-Digital Conversion functionality.
- Supports high-temperature operation up to 125 °C.
Applications
- Embedded control systems requiring CAN bus connectivity
- Industrial automation controllers
- Automotive electronic modules
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status, as indicated in available records, prior to integration. Ensure supply chain stability due to potential end-of-life status associated with legacy National Semiconductor inventory. Validate package integrity upon receipt.
Selection Notes
Select this microcontroller when a 16-bit architecture with native CAN support is required. Consider the 16 MHz processing speed and ADC presence for signal processing tasks. Evaluate the 80-pin QFP footprint against PCB layout constraints. Assess thermal management requirements given the extended industrial temperature range capability.
Part Context
This component belongs to the CR16MCS series of 16-bit microcontrollers designed by National Semiconductor, now part of Texas Instruments. The CR16B core offers efficient code density and performance suitable for complex embedded applications. This specific variant emphasizes connectivity and analog input handling within a robust industrial-grade package.
Replacement Considerations
Consult official datasheets for cross-reference options such as the CR16MCS9VJE8/NOPB. Verify pin compatibility and software register mapping before substitution. Note that newer revisions may include updated packaging or compliance certifications.
