CC2545RTCR

RF Transceiver ICS Overview

The CC2545RTCR is a Texas Instruments RF System-on-Chip designed for 2.4 GHz applications, featuring a high-performance 8051 microcontroller core with code prefetch. It integrates a single-chip 2.4 GHz RF transceiver, 32 kB of in-system programmable flash memory, and 1 kB of SRAM. The device supports up to 31 general-purpose I/O pins and includes multiple serial interfaces such as SPI, UART, and I2C. It operates within a temperature range of -40°C to +85°C and is housed in a VQFN-48 package.

RF Transceiver ICS Procurement Notes

Verify the suffix 'R' indicates reel packaging and 'T' denotes tape-and-reel configuration when ordering. Confirm the specific variant matches the required pinout and memory configuration. Ensure compatibility with existing firmware development tools and debug interfaces. Check moisture sensitivity levels for proper storage and handling procedures during assembly.

RF Transceiver ICS Selection Notes

Select this component for designs requiring integrated RF and MCU functionality without external transceivers. Consider the 32 kB flash size for application code and data storage needs. Evaluate the 31 GPIO count against interface requirements for sensors and actuators. Assess power consumption profiles against battery life expectations for portable applications.

RF Transceiver ICS Part Context

The CC2545 belongs to Texas Instruments' Value Line SoC family, targeting cost-sensitive 2.4 GHz wireless applications. It shares architectural similarities with the CC2541 but offers different memory configurations and pin counts. This series is optimized for simple, robust wireless solutions using standard 8051-based development ecosystems.

RF Transceiver ICS Replacement Considerations

The CC2545RTCR may be substituted with other CC254x series variants depending on memory and pin requirements. Verify pin-to-pin compatibility if replacing with CC2541 or CC2543 models. Ensure software compatibility across the family due to shared peripheral structures.
