The NuMicro® M261KIAAE is a low-power microcontroller platform based on Arm® Cortex®-M23 core for Armv8-M 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 ℃.
Low power and robust security are two major vitals for Internet-of-Things ( IoT ) applications. The NuMicro® M261KIAAE 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® M261KIAAE also integrates RTC with independent VBAT voltage source pin to support low power mode with main power off and VBAT only. Regarding the power consumption of the NuMicro® M261KIAAE, 97 μA / MHz ( LDO mode ) and 45 μA / MHz ( DC-DC mode ) in normal run mode, 2.8 μA in Standby Power-down mode, and less than 2μA in Deep Power-down mode without VBAT. It’s low power, wide supply voltage and fast wake-up features make it suitable for battery-powered IoT applications.
The NuMicro® M261KIAAE 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.
The NuMicro® M261KIAAE provides 4-region programable eXecute-Only-Memory ( XOM ) to secure critical program codes. The AES 256 / 192 / 128 hardware accelerator and True Random Number Generator ( TRNG ) are built-in for data encryption. Six tamper detection pins are implemented to avoid malicious damage from hacker. Accompany with 96-bit Unique Identification ( UID ) and 128-bit Unique Customer Identification ( UCID ) to enhance the product security.
The NuMicro® M261KIAAE integrates Voltage Adjustable Interface ( VAI ), 6 I / O pins to support the 2nd I / O voltage from 1.8 ~ 3.6 V to save level shifter components while connecting to external devices.
The NuMicro® M261KIAAE integrates one set of Secure Digital Host Controllers ( SDHC ), compliant with SD Memory Card Specification Version 2.0. It supports 50 MHz to achieve 200 Mbps at 3.3V operation, and dedicated DMA master with Scatter-Gather function to accelerate the data transfer between system memory and SD / SDHC / SDIO card.
The NuMicro® M261KIAAE is equipped with plenty of peripherals such as Timers, Watchdog Timers, RTC, PDMA, External Bus Interface ( EBI ), Low-power UART, Universal Serial Control Interface ( USCI ), Qual SPI ( QSPI ), SPI/I²S, I²C, Smart Card Interface ( ISO-7816-3 ), GPIOs, 24 channels of PWM, makes it highly suitable for connecting comprehensive external modules and LED lighting control. The NuMicro® M261KIAAE also integrates high performance analog front-end circuit blocks, such as one 16 channels of 12-bit 3.76 MSPS SAR ADC, two 12-bit 1 MSPS voltage type DAC, two rail-to-rail analog comparator ( ACMP ), temperature sensor, low voltage reset ( LVR ) and brown-out detector ( BOD ) to enhance product performance, reduce both external components and form factor.
The package types of NuMicro® M261KIAAE is LQFP128 ( 14 mm x 14 mm ). Pin-to-pin compatible in same package makes optimizing product features and performance easily
Nuvoton NuMaker M261 / M262 / M263 evaluation boards ( NK-M263KI ) and Nu-Link debugger are available for evaluation and product development. 3rd Party IDEs such as Keil MDK, IAR EWARM and NuEclipse IDE with GNU GCC compilers, are also supported.
