TI introduces the industry's first CC2540 Bluetooth low energy system-on-chip and ANT network

Texas Instruments (TI) has launched the industry's first complete Bluetooth low energy solution and the highest integrated ANT network processor to provide ultra-low power short-range wireless connectivity solutions for consumer medical, mobile accessories, sports and health care applications. Using CC2540 single-mode Bluetooth low energy system-on-chip and CC257x ANT network processor, the target application can work continuously for more than 1 year through a button battery.

Low-energy Bluetooth technology is designed for low-cost, low-power, short-range RF connections. In such applications, the focus is on energy consumption (current × time), not just current. Zhou Xiang, business development manager of TI's Analog Devices Division, pointed out that in applications with a large amount of transmitted data, because the data transmission process takes a long time, it is not obvious to optimize energy consumption by shortening the wake-up time; For applications that transmit very little data, the data transfer processing time is shorter, and a large amount of time can be saved by quickly waking up, thereby reducing energy consumption. Therefore, TI's Bluetooth low energy solution is especially suitable for wireless applications with small data transmission.

CC2540 Bluetooth low energy system-on-chip features include:

Single chip device: integrated controller, host and application in 6mm × 6mm package can reduce physical size and reduce cost; based on flash memory: device firmware can be updated in the field, data can be stored on-chip, which can increase flexibility for developers; Complete solution: low-power RF IC, comprehensive embedded single-mode protocol stack, configuration file software and application support; RF performance: excellent long-range link budget (up to + 97dB) and good compatibility with other 2.4GHz devices Coexistence; interoperability / compatibility: single-mode and dual-mode devices that comply with the Bluetooth specification version 4.0 (Bluelink 7.0 Bluetooth / FM single-chip solution, WiLink 7.0 WLAN / GPS / Bluetooth / FM single-chip solution, and WiLink 6.0 WLAN / Bluetooth / FM single chip solution) can realize comprehensive link test and development.

The CC2540 Bluetooth low energy SoC in QFN-40 package is now in mass production, and engineers can use the development kit CC2540MINI-DK to start development immediately. The CC2570 (single channel) and CC2571 (8 channel) ANT in QFN-40 package will be put into mass production in December 2010.

Digital Timer

Instruction Manual

1. Features

Clock display, 10 sets of adjustable timed power control, randomized power control, manual switch and optional DST setup.

2. First time charging

This Timer contains a rechargeable battery. It is normal that the new/old model runs out of battery if it wasn`t being charged for a long period of time. In this case, the screen will not turn on.

To charge : simply plug the timer to a power outlet. The charging time should take at least 15 minutes.

If the screen doesn`t light up or displays garbled characters, simply reboot the system by pressing the [RESET" button.

3. Set clock


Hold [CLOCK" button and [WEEK" button to adjust week.

Hold [CLOCK" button and [HOUR" button to adjust hour.

Hold [CLOCK" button and [MINUTE" button to adjust minute.

Hold [CLOCK" button and [TIMER" button to select 12 hour/24 hour display.

Hold [CLOCK" button and [ON/AUTO/OFF" button to enable/disable DST (daylight-saving-time).

4. Set timer

Press [TIMER" button, select and set timer. Setting rotation : 1on, 1off, 2on, 2off, ...... , 10on, 10off.

Press [HOUR" button to set hour for timer.

Press [MIN" button to set minute for timer.

Press [WEEK" button to set weekday for timer. Multiple weekdays can be selected. ex: if selected [MO", the timer will only apply on every Monday; if selected [ MO, WE, FR", the timer will apply on every Monday, Wednesday and Friday.


Press [RES/RCL" button to cancel the selected on or off timer. The screen will show "-- -- : -- --" , the timer is canceled.

Press [RES/RCL" button again to reactivate the timer.


When timers are set, press [CLOCK" to quit timer setting and return to clock.

5. Random function


Press [RANDOM" button to activate random function, press again to cancel function.

System only runs random function when [AUTO" is on.

Random function will automatically start the timer from 2 to 32 minutes after the setting.

ex : if timer 1on was set to 19:30 with the random function on, the timer will activate randomly between 19:33 to 20:03.

if timer 1off was set to 23:00 with the random function on, the timer will activate randomly between 23:02 to 23:32.

To avoid overlapping, make sure to leave a minimum of 31 minutes gap between different sets of timer.

6. Manual control

Displayed features:

ON : socket turns on.

OFF : socket turns off.

AUTO : socket turns on/off automatically via timer.

Manual ON setting

Press [ON/AUTO/OFF" button to switch from [AUTO" to [ON".

This mode allows socket of the device to power up. Power indicator will light up.

Manual OFF setting

Press [ON/AUTO/OFF" button to switch from [AUTO" to [OFF".

This mode turns socket of the device off. Power indicators will turn off.

7. Electrical parameters

Operating voltage : 230VAC

Battery : NiMh 1.2V

Power consumption : < 0.9W

Response time : 1 minute

Power output : 230VAC/16A/3680W

Q&A

Q: Why won`t my timer turn on?

A: It`s out of battery, you can charge the timer by plugging onto any power outlet. Charge the device for at least 15 minutes. Then press [RESET " button to reset the device.

Q: Can I set seconds of the timer?

A: No, the smallest time unit is minute.

Q: Does my timer keeps old settings without being plugged onto a power outlet?

A: Yes, the timer has an internal battery, it allows the timer to save settings without a power outlet.

Q: Is the battery rechargeable?

A: Yes, the battery is rechargeable. We recommend to charge it for 4 hours so the battery is fully charged.

Q: Does the timer needs internet connection?

A: The timer does not need internet.

Q: Does the screen have back light function?

A: It doesn`t support back light.
