BC840/M/E, Compact BLE 5, Thread, Zigbee Modules

Ver 1.00, April 2019

The 32 bit ARM Cortex M4F MCU with hardware supports for DSP instructions and floating point operations,

code density and execution speed are higher than other Cortex M MCU. The Programmable Peripheral

Interconnect (PPI) system provides a 20-channel bus for direct and autonomous system peripheral

communication without CPU intervention. This brings predictable latency times for peripheral to peripheral

interaction and power saving benefits associated with leaving CPU idle. The device has 2 global power modes

ON/OFF, but all system blocks and peripherals have individual power management control which allows for an

automatic switching RUN/IDLE for system blocks based only on those required/not required to achieve

particular tasks.

The radio supports Bluetooth low energy and ANT. Output power is scalable from a maximum of +8dBm down

to -20 dBm in 4dB steps. Sensitivity is increased to -96 dBm to -89 dBm, depending on data rate. Sensitivity for

BLE is -96 dBm, and -92.5 dBm for ANT.

The NFC block supports NFC-A tags with proximity detection and Wake-on-field from low power mode. The

NFC enables Out-Of-Band (OOB) Bluetooth pairing of devices and thus greatly simplifying deployment.

ARM Trustzone CryptoCell 310

ARM® TrustZone® CryptoCell-310 co-processor is a security subsystem which provides Root of Trust (RoT) and

cryptographic services for a device. CryptoCell services are available to the application through a software library API, not

a hardware register interface.
