The CC2541 is a power-optimized true system-on-chip (SoC) solution for both low energy and proprietary 2.4-GHz applications. It enables robust network nodes to be built with low total bill-of-material costs. The CC2541 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 CC2541 is highly suited for systems where ultralow power consumption is required. This is specified by various operating modes. Short transition times between operating modes further enable low power consumption.
The CC2541 is pin-compatible with the CC2540 in the 6-mm × 6-mm QFN40 package, if the USB is not used on the CC2540 and the I2C/extra I/O is not used on the CC2541.
CC2541主要特性:
CC2541 WITH TPS62730
• TPS62730 is a 2-MHz Step-Down Converter With Bypass Mode
• Extends Battery Lifetime by up to 20%
• Reduced Current in All Active Modes
• 30-nA Bypass Mode Current to Support
• RF Performance Unchanged
• Small Package Allows for Small Solution Size
• CC2541 Controllable
CC2541應(yīng)用:
• 2.4-GHz Bluetooth" title="Bluetooth">Bluetooth low energy Systems
• Proprietary 2.4-GHz Systems
• Human-Interface Devices (Keyboard, Mouse, Remote Control)
• Sports and Leisure Equipment
• Mobile Phone Accessories
• Consumer Electronics

CC2541評估模塊
The CC2541 Evaluation Module Kit contains two CC2541 Bluetooth low energy Evaluation Modules, which can be used either as standalone modules (requires a power source and a simple carrier board like the SoC Battery Board or connected to e.g. the SmartRF05EB Evaluation Boards (included in the CC2540DK) for full control from the PC.
The evaluation modules can be used as a reference board for prototyping and for verifying the performance of the CC2541 RF IC.
CC2541評估模塊主要特性:
The CC2541EMK includes:
? 2 x CC2541EM Evaluation Modules
? 2 x 2.4 GHz Antennas
