GENERAL DESCRIPTION

The NuMicro® M480 series 32-bit microcontroller powered by Arm® Cortex® -M4F with DSP

extension runs up to 192 MHz with 175µA/MHz power consumption. Its 256/512 KB embedded Flash

memory in dual-bank architecture supports Over-The-Air firmware upgrade. The 96/160 KB embedded

SRAM includes 32 KB cache for speeding up code execution from the external SPI Flash. Built-in 4

KB Secure Protection ROM provides a safe space for saving confidential program or data. System

supports a wide voltage range from 1.8V to 3.6V in industrial operating temperature from -40°C to

105°C.

The M480 series is equipped with a large number of high speed digital peripherals, such as a USB 2.0

high speed interface with on-chip transceiver working in device/host/OTG mode, a USB 2.0 full speed

interface with on-chip transceiver working in device/host/OTG mode, up to nine UART interfaces

including three ISO-7816-3 interfaces, up to four composite SPI/I

2S interfaces, a Quad-SPI interface, a

SPI Flash interface supporting quad mode, three I

2C interfaces, a 192 kHz/32-bit I2S interface, two

SDIO interfaces, two CAN 2.0B interfaces, two QEI interfaces, a 10/100 Mbps Ethernet MAC

supporting RMII and two Universal Serial Control Interfaces which can be configured as UART, SPI or

2C. The M480 series also supports 16 channels peripheral DMA and up to 32 channels PWM running

up to 192 MHz.

The M480 series provides high performance analog peripherals, such as a 12-bit 5MSPS SAR ADC

with up to 16 channels, two 12-bit 1MSPS DAC, two analog comparators and three operational

amplifiers, as well as a built-in hardware cryptography accelerator that supports ECC, AES, DES,

triple DES, SHA, HMAC and a random number generator (RNG).

The NuMicro® M480 series includes the following sub-series:



NuMicro® M481 Base series: Delivers high performance computing power with low

power consumption for running complex algorithm.



NuMicro® M482 USB FS OTG series: Built-in USB 2.0 full speed interface with on-chip

OTG transceiver working in device/host/OTG mode.



NuMicro® M483 CAN series: Built-in two sets of CAN 2.0B bus interfaces.



NuMicro® M484 USB HS OTG series: Built-in USB 2.0 high speed interface with on-chip

OTG transceiver working in device/host/OTG mode.



NuMicro® M485 Crypto series: Built-in hardware cryptography engine and random

number generator.



NuMicro® M487 Ethernet series: Built-in 10/100Mbps Ethernet MAC supports industrial

RMII, MDC and MDIO for communicating with an external transceiver.
