CP3CN17K38

Application Specific Microcontrollers Overview

The CP3CN17K38 is a reprogrammable connectivity processor from Texas Instruments featuring the CR16C RISC core. It integrates 256 Kbytes of Flash program memory, 8 Kbytes of Flash data memory, and 10 Kbytes of static RAM. The device supports a maximum operating frequency of 24 MHz with an external 12 MHz input clock. Key peripherals include a Full CAN 2.0B interface, UART, Microwire/SPI, ACCESS.bus, Advanced Audio Interface (AAI), and a CVSD/PCM converter. It utilizes a four-channel DMA controller and offers up to 40 programmable I/O pins in a CSP-48 package.

Application Specific Microcontrollers Feature Summary

• CR16C fully static RISC core operating up to 24 MHz
• On-chip memory: 256 KB Flash program, 8 KB Flash data, 10 KB SRAM
• Full CAN 2.0B interface with 15 message buffers
• Integrated CVSD/PCM converter for audio applications

Application Specific Microcontrollers Applications

• Industrial control systems requiring CAN communication
• Audio processing devices utilizing CVSD/PCM conversion
• Embedded systems needing low-power operation modes

Application Specific Microcontrollers Procurement Notes

Verify the specific suffix 'X' or 'Y' against the datasheet table to confirm packaging type and quantity. The source indicates 'X' corresponds to tape-and-reel packaging with 2500 units, while 'Y' denotes 250 units per reel. Ensure the design accommodates the CSP-48 package constraints and industrial temperature range specifications.

Application Specific Microcontrollers Selection Notes

Select this component when a high-performance RISC core with integrated CAN and audio capabilities is required. The 24 MHz maximum speed and 256 KB Flash provide sufficient resources for complex embedded protocols. Consider the CSP-48 package size if board space is limited, noting that external bus expansion is not available on this package variant.

Application Specific Microcontrollers Part Context

The CP3CN17 series includes variants like the CP3CN17G38 in LQFP-100 packages which support external memory expansion. The K38 suffix specifically identifies the CSP-48 package version without external bus capability. All variants share the same core architecture and peripheral set, differing primarily in physical package and manufacturing lot configuration.

Application Specific Microcontrollers Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Designers should consult Texas Instruments for current equivalent recommendations or verify compatibility with alternative microcontrollers offering similar CAN and RISC core specifications.
