The NuMicro® CM3034 series is a 32-bit microcontroller powered by the Arm® Cortex®-M33 core. It integrates TrustZone® technology, a DSP instruction set, and a Floating-Point Unit (FPU). Designed for high-performance applications, it targets industrial control, smart factories, smart buildings, renewable energy, and consumer electronics. Operating at up to 180 MHz, the CM3034 series supports 1.7V to 3.6V operating voltage and -40°C to +105°C wide operating temperature. It offers diverse packaging options and superior reliability, featuring high immunity with ESD HBM 4 kV and EFT 4.4 kV ratings.
Robust Memory and Security
The CM3034 series provides up to 512 KB of Flash memory with Error Correction Code (ECC), 320 KB of SRAM (including 64 KB with hardware parity check), and an 8 KB user-defined loader (LDROM). To ensure robust security, it supports TrustZone® technology, Secure Boot (Root of Trust, ROT), and Execute-Only-Memory (XOM).
Enhanced Analog Features
The CM3034 series integrates rich analog peripherals, including two analog comparators, up to 16 channels of 12-bit 4.2 Msps SAR ADC, multiple levels of internal voltage reference, a temperature sensor, low-voltage reset (LVR), and a brown-out detector (BOD) to reduce external components and form factors simultaneously.
Extensive Connectivity and Control Peripherals
The CM3034 series supports a comprehensive range of peripherals, including one set of Enhanced LED Light Strip Interface (ELLSI) and 10 sets of LED Light Strip Interface (LLSI) for ARGB Gen1 and Gen2 LED control. It features up to 48 channels of 16-bit PWM, one I3C interface, two CAN FD controllers, and two Universal Serial Control Interfaces (USCI) configurable as UART, I2C, or SPI. Communication capabilities are further extended with five UARTs, three I²C, three SPI/I2S, one Quad-SPI, one SDH, and one USB High-Speed device/host/OTG controller with a built-in transceiver. Furthermore, the CM3034 series incorporates one EQEI, one ECAP, one EBI, and a Real-Time Clock (RTC).
Supported packages include QFN 33-pin, QFN 48-pin, LQFP 48-pin, LQFP 64-pin, and LQFP 128-pin. Package is Halogen-free, RoHS-compliant and TSCA-compliant.
For the development, Nuvoton provides the NuMaker-CM3034HS8 evaluation board, and Nuvoton Nu-Link debugger. The 3rd Party IDE such as Keil MDK Nuvoton Edition, IAR EWARM, and VS Code with support for both Arm Compiler and GNU C Compiler are also available.
