Full-speed device, a 12-bit ADC and 4 sets of 6-channel BPWM. The nUc121/125 series provides the high 50 MHz operating speed, 8 Kbytes SRAM, 8 USB endpoints and 24 channels of BPWM, which make it powerful in USB communication and data processing. The NUC121/125 series is ideal for industrial control, consumer electronics, and communication system applications such as printers, touch panel, gaming keyboard, gaming joystick, USB audio, PC peripherals, and alarm systems The NUC121/125 series runs up to 50 MHz and supports 32-bit multiplier, structure NVIC(Nested Vector Interrupt Control), dual-channel APB and PDMA(Peripheral Direct Memory Access) with CRC function. Besides, the NUC121/125 series is equipped with 32 Kbytes Flash memory, 8 Kbytes SRAM, and 4 Kbytes loader ROM for the ISP. It operates at a wide voltage range of 2.5v 5.5V and temperature range of -40C -+105C. It is also equipped with plenty of peripheral devices, such as 8-channel 12-bit ADC. USCL, UART. SPL. 'C. s. usB 2.0 fs device, and offers low-voltage reset and Brown-out detection, PWM(Pulse-width Modulation), capture and compare features, four sets of 32-bit timers, Watchdog Timer, and internal Rc oscillator. All these peripherals have been incorporated into the nUc121/125 series to reduce component count, board space and system cost Additionally, the NUc 121/125 series is equipped with isP(In-System Programming), lAP(In Application-Programming)and ICP(In-Circuit Programming) functions, which allows the user to update the program under software control through the on-chip connectivity interface, such as SWD, UART and USB. Also all series support SPROM. Moreover, the NUC125 support Voltage Adjustable Interface with individual o(1.8v-55V) for saving additional cost on adjusting the 1.1 Key Features Support Table UScI can be set to uart.c or sPl Product line USBD USCI UART IC SPI/Is Timer BPWM ADC NUC121 4424 24 12 NUC125 1442,4 Table 1. 1-1 Key Features Support Table The NuMicro NUC121/125 series is suitable for a wide range of applications such as USB Keyboard/Mouse Gaming-Joystick O÷m0mamo>→>oTmm Industrial automation Home automation 0 VR peripheral application USB audio Alarm system Aug.17,2018 Page 9 of 148 Rey 1.02 nuVOTon NUc121/125 2 FEATURES 2.1 NuMicro NUC121/125 Features ●Core ARMO Cortex-MO core running up to 50 MHz One 24-bit system timer Supports Low Power Sleep mode Single-cycle 32-bit hardware multiplier Supports programmable 4 level priorities of Nested vectored Interrupt Controller (NVIC) Supports programmable mask-able interrupts Supports Serial Wire Debug(swD)with 2 watch-points/ 4 breakpoints o Built-in LDo for wide operating voltage ranged from 2.5V to 5.5V ● Flash Memory Supports 32 KB application ROM(APROM) Supports 4.5 KB Flash for loader LDROM) Supports 512 bytes Security Protection Rom(SPROM) Supports 12 bytes User Configuration block to control system initiation Supports Data Flash with configurable memory size Supports 512 bytes page erase for all embedded flash Supports In-System-Programming(ISP), In-Application-Programming(lAP)update embedded flash memory Supports crc-32 checksum calculation function Supports flash all one verification function Hardware external read protection of whole flash memory by security Lock Bit Supports 2-wired ICP update through SWD/ICE interface ● SRAM Memory 8 KB embedded sram Supports byte-, half-word-and word-access Supports PDMa mode PDMA(Peripheral DMA) Supports 5 independent configurable channels for automatic data transfer between memories and peripherals mm0D→>0工mm Supports single and burst transfer type Supports normal and scatter-Gather Transfer modes Supports two types of priorities modes: Fixed-priority and Round-robin modes Supports byte-, half-word-and word-access Supports incrementing mode for the source and destination address for each channel Supports time-out function for channel o and channel 1 Supports software and SPI/12S, UART, USCl, USB, ADC, PWM and TiMER request Clock control Built-in 48 MHz internal high speed RC oscillator(HIRC) for USB device operation ( Frequency variation≤2%at-40℃~+105℃) Dynamically calibrating the HIRC OSC to48MHz±0.25%from-40℃to105℃ by external 32. 768K crystal oscillator (LXT) or internal USB synchronous mode Built-in 10 kHz internal low speed RC oscillator for Watchdog Timer and Wake-up operation Supports one interface to connect external crystal oscillator for high speed or low Aug.17,2018 Page 10 of 148 Rey 1.02
