1.3
CPU
The NINA-B2 series has a dual-core system with two Harvard Architecture Xtensa LX6 CPUs with
maximum 240 MHz internal clock frequency. The internal memory of NINA-B2 includes the following:
•
448 Kbyte ROM for booting and core functions
•
520 Kbyte SRAM for data and instruction
•
16 Mbit FLASH for code storage including hardware encryption to protect programs and
data
•
1 kbit EFUSE (non- erasable memory) for MAC addresses, module configuration, Flash-
Encryption, and Chip-ID

Operating modes
Power modes
The NINA-B2 series modules are power efficient devices capable of operating in different power
saving modes and configurations. Different sections of the module can be powered off when not
needed and complex wake up events can be generated from different external and internal inputs.
1.5
Supply interfaces
Module supply design (VCC)
The NINA-B2 series modules use an integrated Linear Voltage converter to transform the supply
voltage presented at the
VCC
pin into a stable system voltage.
