About This Manual
The CC2540/41 is a cost-effective, low-power, and true system-on-chip (SoC) solution for Bluetooth
low-energy applications. It enables robust BLE master or slave nodes to be built with very low total
bill-of-material costs. The CC2540/41 combines the excellent performance of a leading RF transceiver
with an industry-standard enhanced 8051 MCU, in-system programmable flash memory, 8-KB RAM, and
many other powerful supporting features and peripherals. The CC2540/41 is suited for systems where
very low power consumption is required. Very low-power sleep modes are available. Short transition times
between operating modes further enable low power consumption.
The CC2540 comes in two different versions: CC2540F128 and CC2540F256, with 128 KB and 256 KB of
flash memory, respectively.
The CC2541 comes in two different versions: CC2541F128 and CC2541F256, with 128 KB and 256 KB of
flash memory, respectively.
The CC2541F128/F256 comes in two different versions: CC2541F128/F256, with 128 and 256 KB of flash
memory, respectively.
Combined with the Bluetooth low-energy protocol stack from Texas Instruments, the
CC2540F128/CC2540F256 and CC2541F128/CC2541F256 constitute the market’s most comprehensive
single-mode Bluetooth low energy solution.
The CC253x System-on-Chip solution for 2.4 GHz is suitable for a wide range of applications. These can
easily be built on top of the IEEE 802.15.4 based standard protocols ( RemoTI™ network protocol, TIMAC
software, and Z-Stack™ software for ZigBee
®
compliant solutions) or on top of the proprietary SimpliciTI™
network protocol. The usage is, however, not limited to these protocols alone. The CC253x family is, e.g.
also suitable for 6LoWPAN and Wireless HART implementations.
Each chapter of this manual describes details of a module or peripheral; however, not all features are
present on all devices. To see the differences regarding features, see Table 0-1 in the Devices section.
For detailed technical numbers, such as power consumption and RF performance, see the device-specific
data sheet (Appendix C).
