Product Specification

Functions

1. Core Computing Capability
   • Runs on a 32-bit MIPS M5150 core with a maximum operating frequency of 250 MHz, delivering exceptional instruction execution efficiency to handle complex algorithms, multitasking operations, and real-time data processing with ease.
   • Integrates a dedicated DSP module and an enhanced floating-point unit (FPU), supporting high-speed execution of digital signal processing tasks (e.g., FFT, filtering, modulation/demodulation) and precision floating-point calculations, which are essential for applications like motor vector control and industrial measurement.
2. On-Chip Memory Resources
   • Features 2048 KB (2 MB) of on-chip flash memory for storing program codes, firmware, and bootloader programs. It supports both in-system programming (ISP) and in-application programming (IAP), enabling convenient field firmware updates without disassembling the device.
   • Equipped with 512 KB of high-speed SRAM, providing ample space for data buffering, stack operations, and temporary storage of real-time sensor data, ensuring smooth operation of bandwidth-intensive applications.
3. Rich Peripheral Interfaces
   • Communication Interfaces: Includes a full set of industrial-grade communication peripherals, such as 10/100 Mbps Ethernet MAC (compliant with IEEE 802.3), USB 2.0 OTG, CAN FD, multiple SPI/I2C buses, and UART/USART ports. These interfaces enable seamless connectivity with industrial networks, sensors, human-machine interface (HMI) devices, and external storage modules.
   • Analog Peripherals: Integrates a 16-bit high-resolution ADC with high sampling rate, dual-channel DACs, analog comparators, and precision voltage references, supporting accurate acquisition and processing of analog signals for applications like temperature measurement and pressure sensing.
   • Control Peripherals: Comes with advanced motor control peripherals (e.g., high-resolution PWM modules, quadrature encoder interfaces (QEI)), multi-channel timer/counter modules, and a configurable interrupt controller, meeting the requirements of high-precision motion control systems.
4. Power Management and Reliability
   • Supports multiple low-power operating modes (idle, sleep, deep sleep), allowing dynamic adjustment of power consumption based on application scenarios, which is ideal for battery-powered embedded devices and energy-efficient industrial systems.
   • Complies with industrial-grade standards, with an operating temperature range of -40 °C to 125 °C. It incorporates flash memory error correction code (ECC), watchdog timer (WDT), and brown-out detection (BOD) circuits, ensuring stable and reliable operation in harsh industrial environments with electromagnetic interference and voltage fluctuations.
5. Package and Scalability
   • Adopts a 144-pin TQFP (Thin Quad Flat Package) with a surface-mount design, offering a high number of I/O pins for connecting external devices and expanding system functions.
   • Supports external memory expansion via dedicated bus interfaces (e.g., SDRAM, NOR flash), enabling scalability for applications that require large storage capacity or extended processing capabilities.
