High-performance NuMicro® Family Arm Cortex®-M4 based Microcontroller (MCU) with FPU and DSP extension

The NuMicro Family Cortex-M4 based MCUs support floating-point unit (FPU, single-precision only IEEE-754 compliant) and DSP extension, including single cycle 16/32-bit MAC, single cycle dual 16-bit MAC, and 8/16-bit SIMD arithmetic. The Cortex-M4 core is powered by ARMv7E-M architecture with a 3-stage pipeline.

The NuMicro Family Cortex-M4 based MCUs provide high performance system design up to 90-240 DMIPS operating at up to 72-192 MHz. When executing from the embedded Flash memory, the power consumption can be down to 130 μA/MHz with dynamic power scaling function supported by the M480 series.

The NuMicro Family Cortex-M4 based MCUs comprise following product series.

  • M480 Series: 192 MHz core speed, 512/256 KB Flash memory, 160/128 KB SRAM, Secure Boot, 1.8V to 3.6V operating voltage, ETM
    • M481 – Dual 12-bit 5 MSPS ADC, Quadrature Encoder Interface (QEI), 16-ch 192 MHz PWM
    • M482 – USB 2.0 Full Speed device/host/OTG with integrated FS transceiver and 1 KB data buffer, crystal-less in USB device mode, camera interface
    • M483 – 3x CAN 2.0B, 24-ch 12-bit 5 MSPS ADC,
    • M484 – USB 2.0 High Speed device/host/OTG with integrated HS transceiver and 4 KB data buffer, dual USB interface
    • M485 – Hardware cryptography engine including ECC-256, AES-256, and SHA-512
