GENERAL DESCRIPTION
®
®
The NuMicro M261/M262/M263 series 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. The 32-bit low-power microcontrollers supports low supply voltage from 1.8 ~
3.6V and operating temperature range from -40 ~ +105 ℃.
Low-power Technology for IoT application
Low power and robust security are two major vitals for Internet-of-Things (IoT) applications. The
®
NuMicro M261/M262/M263 series 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 M261/M262/M263 series
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
M261/M262/M263 series, 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. It’s
low power, wide supply voltage and fast wake-up features make it suitable for battery-powered
IoT applications.
Secure Boot - Make sure your products in secure execution
®
The NuMicro M261/M262/M263 series 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.
M261/M262/M263 SERIES PRODUCT BRIEF
eXecute-Only-Memory (XOM) - Protect the intelligent property of developers
®
The NuMicro M261/M262/M263 series 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. Up to 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.
Voltage Adjustable Interface (VAI) - Support 2
nd
I/O voltage without level-shifter
®
The NuMicro M261/M262/M263 series integrates Voltage Adjustable Interface (VAI), up to 6 I/O
nd
pins to support the 2 I/O voltage from 1.8 ~ 3.6V to save level shifter components while
connecting to external devices.
Secure Digital Host Controller (SDHC)
®
The NuMicro M261/M262/M263 series 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.
Rich Pheripherals for comprehensive product application scenarios
®
The NuMicro M261/M262/M263 series is equipped with plenty of peripherals such as Timers,
Watchdog Timers, RTC, PDMA, External Bus Interface (EBI), Low-power UART, Universal Serial
2
Control Interface (USCI), Qual SPI (QSPI), SPI/I²S, I C, Smart Card Interface (ISO-7816-3),
GPIOs, up to 24 channels of PWM, makes it highly suitable for connecting comprehensive
®
external modules and LED lighting control. The NuMicro M261/M262/M263 series 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

M261/M262/M263 Series
(ACMP), temperature sensor, low voltage reset (LVR) and brown-out detector (BOD) to enhance
product performance, reduce external components and form factor simultaneously.
USB 2.0 Full Speed On-The-Go (OTG) supporting Crystal-less function
®
®
The part numbers of NuMicro M262/M263 series are all based on NuMicro M261 series, it
integrates USB 2.0 Full Speed On-The-Go (OTG) transceiver, compliant with USB OTG
Supplement 2.0, can configurable as host-only, device only or ID-dependent. It also integrates
®
USB 1.1 Host Controller and USB 2.0 Full Speed Device Controller. The NuMicro M262/M263
series supports crystall-less function that can generate precise frequency required by USB
protocol without the need of external crystal, to reduce both the BOM cost and PCB size.
Controller Area Network (CAN)
®
®
The part numbers of NuMicro M263 series are all based on NuMicro M261 series, it supports
one set of CAN 2.0B controllers, the bit rate can be programmed to values up to 1MBit/s. This
CAN bus can be set to be one of six paired I/Os by PinConfigure.
Available Packages
®
The NuMicro M261/M262/M263 series provides 9 product part numbers. The package types of
®
NuMicro M261/M262/M263 series includes QFN33 (5mm x 5mm)、LQFP64 (7mm x 7mm) and
LQFP128 (14mm x 14mm). Pin-to-pin compatible in same package makes optimizing product
