The M2351 Series is a secure microcontroller (MCU) platform powered by ARM® Cortex®-M23 core with ARMv8-M architecture, TrustZone® technology, security technologies, peripherals and tools. The ultra-low-power 32-bit microcontroller works in low voltage range from 1.62V to 3.6V and can operate at up to 48 MHz frequency, with up to 512 Kbytes embedded Flash memory in dual bank mode supporting OTA firmware update and up to 96 Kbytes embedded SRAM. It is suitable for applications such as IoT secure connections, fingerprint authentication, EMV card reader, security alarm system, smart home appliance, wireless sensor node device (WSND), auto meter reading (AMR) and portable wireless data collector.
The M2351 series is equipped with 32 Kbytes Secure Boot ROM as root of trust, multiple firmware programming tools by In-System Programming (ISP), In-Circuit Programming (ICP) and In-Application Programming (IAP). In addition to TrustZone software protection mechanism, it also supports eXecution Only Memory (XOM), LDROM (user program loader) and multiple cryptographic hardware accelerators which are used to protect the core software and data assets on a microcontroller system. The M2351 series also integrates a 8 COM x 40 SEG controller with internal charge pump for segment LCD panel and provides high performance connectivity peripheral interfaces such as UART, SPI, I²C, GPIOs, USB and ISO 7816-3 for smart card reader.
As to Power efficiency, the M2351 series supports Brown-out detector, Power-down mode with RTC turn on, RAM retention less than 2.0 uA, deep power-down mode with RAM retention less than 1 uA and fast wake-up via multiple peripheral interfaces.

Nuvoton Technology was founded to bring customers new solutions inspired by innovation. The company was spun-off as a Winbond affiliate in 2008 while Winbond continues to focus on its large Memory business.
From those beginnings we are relatively new up-and-coming digital/analog/mixed signal semiconductor company. Public since just September 27, 2010 on the Taiwan Stock Exchange (TSE) , we are bringing new solutions to our customers that change the world around us.
The Nuvoton portfolio includes products previously under Winbond and those that have grown organically including:
Computer: Super IO (SIO) , Embedded Controllers (EC) , Trusted Platform Modules (TPM) , Power Management among others.
We are one of the world's top three suppliers of Super IO, Embedded Controllers and Trusted Platform Modules for the PC industry.
Microcontrollers: ARM® Cortex™ M0 plus ARM® 7/ ARM® 9 with others in development plus 8051 families.
We are a leader in microcontrollers with our new fast growing portfolio of ARM® Cortex™ microcontrollers plus a family of 8051 products. These families currently include a wide range of ARM® controllers including Cortex™ M0, ARM® 7/ ARM® 9 with more to come.
Mixed Signal: Speech Playback and Record Products with embedded Flash. Audio Products including Power Amplifiers, Audio ADC's/DAC's and CODECS.
We also lead the industry with extremely high fidelity solutions for speech recording/playback and full range audio applications that serve consumer, automotive, white goods and other markets.
Headquartered in Hsinchu, Taiwan, Nuvoton has subsidiaries in the U.S.A., Mainland China, Israel,and India to strengthen regional support and global management.
