Introduction
The SAPPHIRE evaluation board includes Toshiba Bluetooth LE IC complies with Bluetooth v4.2, low energy single-mode radio.
Toshiba Bluetooth LE IC is
・
Compliant with Bluetooth v4.2 low energy system
・
Operating frequency: 2.4 GHz ISM band at 2400-2483.5 MHz (40 RF channels; f=2402+k*2 MHz, k=0, … ,39)
・
Maximum output power level: 0dBm (typ.)
This time, we made following changes.
・
Flash memory’s capacity in the IC (BTLE IC) is changed from 256KB to 128KB for cost saving
・
ROM in the IC (BTLE IC) is changed from 384KB to 216KB for cost saving
・
RAM in the IC (BTLE IC) is changed from 192KB to 128KB for cost saving
・
A random number generator for security is newly added in the IC(BTLE IC)
・
A 32kHz silicon oscillator in the IC(BTLE IC) is deleted for cost saving
・
Some components/parts (IC6, CN12, X3, S2) are newly added for using CMSIS-DAP

-About A Randam Number Generator-
A random number generator is used to generate the key of the encrypted protocol.
-About CMSIS-DAP-
CMSIS-DAP is the interface firmware for a Debug Unit that connects the Debug Port to USB. Debuggers, which execute on a host computer, connect via USB
to the Debug Unit and to the Device that runs the application software. The Debug Unit connects via JTAG or SWD signals to the target Device. ARM Cortex
processors provide the
CoreSight Debug and Trace Unit.
CMSIS-DAP supports target devices that contain one or more Cortex processors.
