2.1 Product Information
The AW2540 is a cost-effective, low-power for Bluetooth low energy applications. It
enables robust BLE master or slave nodes to be built with very low total bill-of-material
costs. It combines an excellent 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 AW2540 is suitable 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 modules can be roughly divided into one of three categories: CPU-related
modules; modules related to power, test, and clock distribution; and radio-related modules。
CPU and Memory：
The 8051 CPU core is a single-cycle 8051-compatible core. It has three different memory
access busses (SFR,DATA, and CODE/XDATA), a debug interface, and an 18-input
extended interrupt unit。
8 KB SRAM and 128/256 KB flash
Peripherals：
A versatile five-channel DMA controller is available in the system, accesses memory using
the XDATA memory space, and thus has access to all physical memories. Each channel
(trigger, priority, transfer mode, addressing mode, source and destination pointers, and
transfer count) is configured with DMA descriptors that can be located anywhere in memory.
Many of the hardware peripherals (AES core, flash controller, USARTs, timers, ADC
interface, etc.) can be used with the DMA controller for efficient operation by performing
data transfers between a single SFR or XREG address and flash/SRAM.
The debug interface implements a proprietary two-wire serial interface that is used for
in-circuit debugging.Through this debug interface, it is possible to erase or program the
entire flash memory, control which oscillators are enabled, stop and start execution of the
user program, execute instructions on the 8051 core, set code breakpoints, and single-step
through instructions in the code. Using these techniques, it is possible to perform in-circuit
debugging and external flash programming elegantly.
USART 0 and USART 1 are each configurable as either an SPI master/slave or a UART.
They provide double buffering on both RX and TX and hardware flow control and are thus
well suited to high-throughput full-duplex applications. Each USART has its own
high-precision baud-rate generator, thus leaving the ordinary timers free for other uses.
When configured as SPI slaves, the USARTs sample the input signal using SCK directly
instead of using some oversampling scheme, and are thus well-suited for high data rates。
The interrupt controller services a total of 18 interrupt sources, divided into six interrupt
groups, each of which is associated with one of four interrupt priorities. I/O and sleep timer
interrupt requests are serviced even if the device is in a sleep mode (power modes 1 and 2)
by bringing the AW2540 back to the active mode。
2.2 Operating conditions
The operating conditions are the physical parameters that AW2540 can operate within.

Caution: Any changed or modifications not expressly approved by the party responsible
for compliance could void the user`s authority to operate this equipment.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1) this device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired
operation.
Note: This equipment has been tested and found to comply with the limits for a Class B
digital device,pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user
is encouraged to try to correct the interference by one or more of the following measures:
—Reorient or relocate the receiving antenna.
—Increase the separation between the equipment and receiver.
—Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected.
—Consult the dealer or an experienced radio/TV technician for help.
This device complies with FCC radiation exposure limits set forth for an uncontrolled
environment.
This device should be installed and must not be co-located or operating in conjunction with
any other antenna or transmitter.
The module in this product is labeled with its own FCC ID and the FCC ID is not visible
when the module is installed inside another device. To satisfy FCC exterior labeling
requirements, the following text must be placed on the exterior of the end product.
