The NuMicro® M480 series is a high performance, low power microcontroller powered by the Arm® Cortex®-M4F core with DSP extension. The 512 KB embedded dual bank Flash memory supports OTA (Over-The-Air) firmware upgrade, and the 160 KB embedded SRAM includes 32 KB cache to speed up external SPI Flash code execution. The 256 KB embedded single bank Flash memory supports up to 4 configurable eXecute-Only-Memory regions, and the 128 KB embedded SRAM provides multi-level retention in standby power-down mode. The factory pre-loaded bootloader enables Secure Boot functionality to check code integrity inside embedded Flash memory.

5. Introduction of NuMicro M480 Series
5
The NuMicro® M480 series is a high
performance, low power microcontroller
powered by the Arm® Cortex®-M4F core
with DSP extension.
Running up to 192 MHz with 175 or
130 µA/MHz dynamic power
consumption provides excellent
energy efficiency.
The 512 KB embedded dual bank Flash
memory supports OTA (Over-The-Air)
firmware upgrade, and the 160 KB
embedded SRAM includes 32 KB cache to
speed up external SPI Flash code execution.
The 256 KB embedded single bank Flash
memory supports up to 4 configurable
eXecute-Only-Memory regions, and the
128 KB embedded SRAM provides multi-
level retention in standby power-down
mode.
The factory pre-loaded bootloader delivers Secure Boot functionality to
check code integrity inside embedded Flash memory.
