series includes a total of 33 ARM Cortex -M4F based products, including the M451 Base Series, M452 USB Series, M453 CAN Series, and M451M Series which is pin compatible with M051 LQFP48 and M058S LQFP64. By planning a complete product line, Nuvoton hopes to ® ® fulfill the demand for the ARM Cortex -M4F core with products at all levels and realize its customer commitment: total support for long-term competitiveness enhancement, and to fulfill their current product development demand and future innovation imagination. ® ® The M451 series embedded with the ARM Cortex -M4F core supports DSC (digital signal controller) and FPU (float point unit) and features high performance computing capability running up to 72 MHz, built-in 256/128/72/40 KB Flash ROM, 32/16 KB SRAM complying with IEC60730 and independent 4 KB in-system programming Flash ROM for developing more flexible online 2 upgrade code that support external UART, SPI, I C, CAN and USB. It also supports EBI to provide greater flexibility for external memory. The entire M451 series is provided with outstanding specifications: four 32-bit timers, dual watchdogs, and integrates plenty of peripherals such as PDMA and RTCs, five UARTs that support 16-byte FIFO, three sets of SPI controllers 2 that support quad mode, two I²C devices that support SMBus and PMBus, two sets of I S, two LINs, CAN bus, ISO-7816-3 interface, full-speed USB OTG, full-speed USB devices, 16-channel 12-bit ADC with 1 MSPS conversion rate, built-in reference voltage (VREF) for circuit generation, 12-bit DAC, two analog comparators and temperature detectors. The M451 series provides two special designs. One is high-resolution 144 MHz PWM with highspeed electromechanical control timer and resolution= 2.9V Vref2 Vref(2.048V) 1.986 2.048 2.109 V AVDD >= 2.5V Vref3 Vref(3.072V) 2.98 3.072 3.164 V AVDD >= 3.4V Vref4 Vref(4.096V) 3.973 4.096 4.219 V AVDD >= 4.5V Min.
