DESCRIPTION
The CC2541 is a power-optimized true system-on-
chip (SoC) solution for both Bluetooth 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. Compared to the CC2540, the
CC2541 provides lower RF current consumption. The
CC2541 does not have the USB interface of the
CC2540, and provides lower maximum output power
in TX mode. The CC2541 also adds a HW I²C
interface.
The CC2541 is pin-compatible with the CC2533
RF4CE-optimized IEEE 802.15.4 SoC.
The CC2541 comes in two different versions:
CC2541F128/F256, with 128 KB and 256 KB of flash
memory, respectively.
