NINA-W1 series
Stand-alone Wi-Fi, Bluetooth and multiradio modules
User Manual
Abstract
This document describes the system integration of NINA-W1 series stand-alone modules, which
includes the NINA-W13 (Wi-Fi) and NINA-W10 and NINA-W15 series (multiradio) and NINA-B2
(Bluetooth) modules. These modules feature a number of useful embedded security features,
including secure boot that ensures that only authenticated software can run on the module. NINA-
W1 modules are ideal for critical IoT applications where security is important. The modules connect
to a host system using UART, high-speed RMII, or GPIO interfaces.

NINA-W1 series - User Manual System description Overview The NINA-W1 series of wireless and multiradio MCU IoT is suitable for industrial markets where security is important. NINA-W1 includes the following stand-alone modules: Model Description NINA-W13 series Wireless MCU modules integrate a powerful microcontroller (MCU) and a Wi-Fi radio for wireless communication. -
Page 6: Cpu
NINA-W1 series modules include an additional voltage supply input for setting the I/O voltage level. A separate VCC_IO pin enables module integration in many applications with different voltage supply levels (1.8 V or 3.3 V for example) without level converters. NINA-W1 series modules currently support 3.3 V IO levels only. -
Page 7: System Function Interfaces
If decoupling capacitors are needed on the supply rails, it is best practice to position these as close as possible to the NINA-W1 series module. The power routing of some host system designs makes decoupling capacitance unnecessary. -
Page 8: Ethernet (Rmii+Smi)
On NINA-W15, direct MAC to MAC connection will be supported when the module reaches Engineering Sample status. NINA-W1 series modules include a full RMII for Ethernet MAC to PHY communication using the included Station Management Interface (SMI). The RMII and SMI uses nine signals in total. The interface requires an external 50 MHz clock source either from a compatible PHY chip or from an external oscillator. - Page 9 RMII_CLK input (GPIO27) at startup. If an RMII clock is discovered, then Ethernet communication is initiated. During startup of NINA-W1 series modules the RMII clock must be started within 100 us, but not before an initial delay of 1.2 ms.
