BLE SoC senses tire pressure
A BLE-enabled TPMS built with the DA14585 does not require a microcontroller. The part handles all of the processing for a TPMS, while bringing the added benefits of security, upgradable firmware, and connectivity to automobile computers via a single node for all Bluetooth Low Energy functions.
The DA14585 supports all Bluetooth developments up to and including Bluetooth 5 and Bluetooth Low Energy mesh. Along with its ARM Cortex-M0 CPU, the device integrates 96 kbytes of RAM (double that of its predecessor), as well as 64 kbytes of one-time programmable memory. The chip even furnishes a microphone interface for voice support. In addition to TPMS applications, the DA14585 can be used for remote controls, proximity tags, beacons, connected medical devices, and smart home nodes.
Housed in a QFN40 package, the DA14585 costs approximately $1.98 in lots of 1000 units and is available through Dialog Semiconductor’s distributor network.
