The secure boot is a chain of secure process for verifying each software identity and integrity on the system. Secure boot can help to make sure that a device boots using only software that is trusted by the original developer. When the MCU starts, the firmware checks the signature of boot software, if the signatures are valid, the MCU boots, and the firmware gives control to the operating system. Otherwise, the system will not run at all.\u003c\/p\u003e\u003cp\u003eThe NuMicro\u003csup\u003e®\u003c\/sup\u003e M261KIAAE provides 4-region programable eXecute-Only-Memory ( XOM ) to secure critical program codes.

The secure boot is a chain of secure process for verifying each software identity and integrity on the system. Secure boot can help to make sure that a device boots using only software that is trusted by the original developer. When the MCU starts, the firmware checks the signature of boot software, if the signatures are valid, the MCU boots, and the firmware gives control to the operating system. Otherwise, the system will not run at all.\u003c\/p\u003e\u003cp\u003eThe NuMicro\u003csup\u003e®\u003c\/sup\u003e M262ZIAAE provides 4-region programable eXecute-Only-Memory ( XOM ) to secure critical program codes.

architecture. It runs up to 64 MHz with 512 Kbytes embedded Flash memory in dual bank mode supporting Over-The-Air ( OTA ) firmware update and 96 Kbytes embedded SRAM. It also supports low supply voltage from 1.8 ~ 3.6 V and operating temperature range from - 40 ~ + 105 ℃.\u003c\/p\u003e\u003cp\u003eLow power and robust security are two major vitals for Internet-of-Things ( IoT ) applications. The NuMicro\u003csup\u003e®\u003c\/sup\u003e M262SIAAE provides multi power modes for diverse operating scenarios, such as Power-down mode ( PD ), Fast Wake-up Power-down mode ( FWPD ), Low Leakage Power-down mode ( LLPD ), Ultra Low Leakage Power-down mode ( ULLPD ), Standby Power-down mode ( SPD ) and Deep Power-down mode ( DPD ). The NuMicro\u003csup\u003e®\u003c\/sup\u003e M262SIAAE also integrates RTC with independent V\u003csub\u003eBAT\u003c\/sub\u003e voltage source pin to support low power mode with main power off and V\u003csub\u003eBAT\u003c\/sub\u003e only.

The secure boot is a chain of secure process for verifying each software identity and integrity on the system. Secure boot can help to make sure that a device boots using only software that is trusted by the original developer. When the MCU starts, the firmware checks the signature of boot software, if the signatures are valid, the MCU boots, and the firmware gives control to the operating system. Otherwise, the system will not run at all.\u003c\/p\u003e\u003cp\u003eThe NuMicro\u003csup\u003e®\u003c\/sup\u003e M262SIAAE provides 4-region programable eXecute-Only-Memory ( XOM ) to secure critical program codes.

architecture. It runs up to 64 MHz with 512 Kbytes embedded Flash memory in dual bank mode supporting Over-The-Air ( OTA ) firmware update and 96 Kbytes embedded SRAM. It also supports low supply voltage from 1.8 ~ 3.6 V and operating temperature range from - 40 ~ + 105 ℃.\u003c\/p\u003e\u003cp\u003eLow power and robust security are two major vitals for Internet-of-Things ( IoT ) applications. The NuMicro\u003csup\u003e®\u003c\/sup\u003e M262KIAAE provides multi power modes for diverse operating scenarios, such as Power-down mode ( PD ), Fast Wake-up Power-down mode ( FWPD ), Low Leakage Power-down mode ( LLPD ), Ultra Low Leakage Power-down mode ( ULLPD ), Standby Power-down mode ( SPD ) and Deep Power-down mode ( DPD ). The NuMicro\u003csup\u003e®\u003c\/sup\u003e M262KIAAE also integrates RTC with independent V\u003csub\u003eBAT\u003c\/sub\u003e voltage source pin to support low power mode with main power off and V\u003csub\u003eBAT\u003c\/sub\u003e only.

It’s low power, wide supply voltage and fast wake-up features make it suitable for battery-powered IoT applications.\u003c\/p\u003e\u003cp\u003eThe NuMicro\u003csup\u003e®\u003c\/sup\u003e M262KIAAE provides secure boot function for a system developer to create a secure execution system in the microcontroller. The secure boot is a chain of secure process for verifying each software identity and integrity on the system. Secure boot can help to make sure that a device boots using only software that is trusted by the original developer. When the MCU starts, the firmware checks the signature of boot software, if the signatures are valid, the MCU boots, and the firmware gives control to the operating system. Otherwise, the system will not run at all.\u003c\/p\u003e\u003cp\u003eThe NuMicro\u003csup\u003e®\u003c\/sup\u003e M262KIAAE provides 4-region programable eXecute-Only-Memory ( XOM ) to secure critical program codes.
