4. Nuvoton (Xintang Technology), an agent of Kaitai Group, a subsidiary of the General Assembly, launched the new 32-bit Cortex ™ -M0 microcontroller series—Mini51 mini core.

Nuvoton (Xintang Technology) announced the launch of the new 32-bit Cortex â„¢ -M0 microcontroller series --- Mini51 mini core. Nuvoton's Mini51 series are highly integrated microcontrollers, continuing the characteristics of the M051 series, using ARM's Cortex-M0 processor, built-in various analog and mixed-signal devices, a variety of high-speed communication devices, to meet customer requirements for streamlining program code, Small packaging, low power consumption, low cost and high performance are required.

Nuvoton's Mini51 series uses ARM® Cortex ™ -M0 as the core, the main frequency is up to 24MHz (21.6 DMIPS) performance, built-in 32-bit multiplier, nested interrupt control structure NVIC; built-in 4K ~ 16K Bytes, 2K Bytes SRAM Programmable Data Flash, integrated high-speed communication peripherals: SPI, I2C, UART; analog peripheral parts, providing 8-channel 10-bit ADC, 2-channel comparator, built-in POR / BOD reset circuit: fast / slow power-on, power supply Drop / plug reset detection function. In addition, the Mini51 series also has 6-channel pulse width modulation PWM with dead zone control, center alignment function, 2 sets of 32-bit clock TImer, internal 10K RC drive high-reliability watchdog, high-precision RC oscillator, built-in frequency automatic The correction circuit can be automatically corrected by an external 32.768 KHz full temperature and full pressure range within ± 1%. Use QFN33 (5mmx5mm), QFN33 (4mmx4mm) and LQFP48 (7mmX7mm) packages, the same package provides different program space size. For applications with limited space, the Mini51 series QFN33 (4mmx4mm) package is the best choice.

5. SiTIme, an agent of Kaitai Group, a subsidiary of the United Nations General Assembly, launched the silicon electromechanical system (Silicon MEMS) clock product. The reference frequency signal is as important as all heartbeats for all electronic products. The movement of all electronic circuits is repeated and stable. As the reference signal source. A well-designed frequency signal is almost an important basis for whether the system can achieve high performance, continuous and stable operation.

Generally speaking, the reference frequency signal of system design can be generated by different frequency devices, such as resonator (Resonator), oscillator (Oscillator) and frequency generator (Clock Generator). Different system designs will be considered according to different designs. Choose a different device to provide the reference frequency. The resonator uses the principle of mechanical vibration and an external resonant circuit to generate periodic oscillation signals. Generally, the resonant circuit is integrated into the chip. The oscillator device integrates the resonator and resonant circuit in a 4 or 6 pin package to output the reference frequency signal. The frequency generator is a relatively complex frequency signal output device. Generally, this type of device requires an external reference resonator, and internally integrates one or more phase lock loops (Phase Lock Loop; PLL) to generate one or several references. Frequency output signal. For all system designs, no matter what frequency device is used as the reference signal in circuit design, a stable and good quality periodic signal is required, including a good waveform, duty cycle, short climb time and fall time ( rising TIme & falling time) and accurately repeating edge time.

SiTime replaces the traditional quartz crystal design with Silicon MEMS technology design. In addition to innovative MEMS resonator technology, the internal design of MEMS oscillators is also constantly improving. The use of MEMS resonators to achieve varying output frequency efficiency and the use of Sigma-Delta Fran-N PLL phase-locked loops as frequency doubling circuits have also become technical design points. Highly integrated MEMS technology, low-power circuit design and circuit module, ultra-small and ultra-thin packaged MEMS oscillator is more attractive for the design of portable products, and its programmable function can also satisfy designers to shorten the product development cycle and quickly, Mass delivery requirements.

SiTime product packaging includes SMD 2.5 mm x 2.0 mm, 3.2 mm x 2.5 mm, 5.0 mm x 3.2 mm, 7.0 mm x 5.0 mm.
