Low-power wireless microcontrollers MCUs simplify IoT designs
Mouser is now stocking the ultra low-power SimpleLink wireless
microcontrollers (MCUs) from Texas Instruments (TI). The wireless MCUs
target Bluetooth Smart, ZigBee and other 2.4GHz RF applications. The
SimpleLink Wireless MCU platform is very low power with low active RF and
run current requirements and provide long battery life when used with small
coin-cell batteries or in energy-harvesting applications, says the company.
The TI CC26xx SimpleLink MCUs are available in three product models. The
CC2650 has a 48MHz ARM(r) Cortex M3 core paired with a 2.4GHz RF transceiver
compatible with Bluetooth Smart, ZigBee, 6LoWPAN, and other IEEE 802.15.4
protocols. The CC2640 also has a 48MHz ARM Cortex M3 with a Bluetooth Smart
radio for systems targeting compliance with ETSI EN 300 328 (Europe), EN 300
440 Class 2 (Europe), FCC CFR47 Part 15 (US), and ARIB STD T66 (Japan). The
CC2630 has a 48MHz ARM Cortex M3 and has a 2.4GHz RF transceiver with an
IEEE 802.15.4 PHY and MAC for ZigBee and 6LoWPAN.
Each of the three wireless solutions offers a rich feature set of timers and
peripherals. A dedicated ARM Cortex M0 on each core manages the radio
sections from code embedded in unchangeable ROM. The platform is code and
pin-compatible and support Bluetooth Smart, ZigBee, 6LoWPAN, sub 1 GHz,
RF4CE and proprietary modes up to 5Mbps, which allows developers to leverage
PC board designs across different wireless systems.
Each solution is supported by ready to use protocol stacks for Bluetooth,
TCP/IP, RTOS, and others. Several development systems are available
including the Texas Instruments SimpleLink Bluetooth Smart SensorTag Kit
(CC2650STK), allowing developers to quickly receive sensor-based data
through their cloud-connected IoT designs.
