CC2620F128RSMT

RF Transceiver ICS Overview

The CC2620F128RSMT is a SimpleLink ultra-low power wireless MCU from Texas Instruments, featuring an ARM Cortex-M3 core operating at 48 MHz. It integrates a 2.4 GHz RF transceiver supporting IEEE 802.15.4 and Zigbee protocols. The device includes 128 kB of flash memory and 20 kB of SRAM. It operates on a supply voltage range of 1.8 V to 3.8 V. Key electrical parameters include a receiver sensitivity of -100 dBm, maximum data rate of 250 kbps, and output power of 0 dBm. Current consumption is approximately 5.9–6.1 mA during reception and 6.1–9.1 mA during transmission. It is housed in a 32-VQFN package with a bare pad.

RF Transceiver ICS Feature Summary

• Industrial sensor nodes
• RF4CE remote controls

RF Transceiver ICS Procurement Notes

Verify the suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the specific variant matches the required memory size and package type against the official datasheet. Ensure compatibility with the intended wireless protocol stack. Check for moisture sensitivity level requirements during storage and handling.

RF Transceiver ICS Selection Notes

Choose this component for applications requiring Zigbee or 802.15.4 connectivity with moderate processing needs. Compare against CC2620F128RSMR if reel packaging is not required. Consider the CC13xx series if sub-1 GHz frequency bands are needed instead of 2.4 GHz. Evaluate current consumption profiles against application duty cycles.

RF Transceiver ICS Part Context

This part belongs to the Texas Instruments SimpleLink CC26xx family of wireless MCUs. It is designed for low-power wireless applications using the ARM Cortex-M3 core. The family supports various protocols including Zigbee, Thread, and proprietary RF. It competes in the market for integrated wireless microcontrollers requiring high efficiency and small form factors.

RF Transceiver ICS Replacement Considerations

CC2620F128RSMR is a direct functional equivalent with different packaging (tray vs. reel). CC2620F128RGZR offers the same functionality in a QFN package. Verify pinout and software compatibility before substitution.
