Xinhai launches pin-compatible MCU, ADC, AFE

Founded in 2003, Chipsea Technology is a full signal chain chip design company integrating perception, computing, control, and transmission. Its products include high-precision ADC, high-performance analog front-end AFE, MCU, mixed-signal SOC, high-precision pressure sensing (Force Touch), etc.

CS32F030/031 series industrial signal chain MCU, using ARM Cortex-M0 core, frequency 48MHz, up to 64KB flash memory and 8KBSRAM, with rich communication interfaces and up to 11 timers. This series is pin-compatible with a certain international brand 32-bit ARM Cortex MCU series. Compared with other brands, Xinhai has the following advantages in compatibility:

-Replacement can be completed in half a day, with supporting application guide

-Registers are compatible with some source code programs, and the original hex file can be burned directly

The model with the largest shipment volume is CS32F030C8T6 (LQFP48), which can be sampled. Other models that can be sampled are:

CS32F030K6T6 (LQFP32)

CS32F030F6P6 (TSSOP20)

CS32F031K8U6 (QFN32)

CS32F031C8T6 (LQFP48)

In addition, Xinhai's newly launched Sigma-Delta ADC CS123x series is pin-compatible with a certain international brand's single-channel 20-bit, 80SPS ADC and dual-channel 24-bit, 80SPS, differential ADC; the high-performance AFE CS125x series with 24-bits ADC and BIM can functionally replace a certain international brand's dual-channel 16-bit weight scale and body composition measurement analog front-end AFE.

Xinbaiwei launches pin-compatible ADC, DAC and USB controller

Corebai was founded in 2014. Its products include amplifiers, interface circuits, power management, time-to-digital converters, DAC digital-to-analog conversion, ADC analog-to-digital conversion, etc. Corebai

's ADC products are widely used in communication instruments, energy, medical equipment, instrumentation measurement systems, motor and power controllers, industrial automation equipment, etc., and are pin-compatible with some series of a well-known international ADC brand: such as 16-bit four-channel, sampling rate 125MSPS ADC; 16-bit dual-channel, sampling rate 105MSPS, high-speed ADC; dual-channel 8-bit high-performance, low-power, sampling rate 1.5GSPS ADC, etc.

At present, high-speed and high-precision DAC products in the world are mainly monopolized by American companies. The DAC products launched by Corebai meet most communication and industrial control customer applications.

Among them, high-speed DAC and DDS products are mainly used in the digital RF transmission terminal market, base station communications (LTE and GSM), point-to-point microwave RF, satellite communications, cable TV, radar and test equipment. Some series are pin-compatible with internationally renowned DAC brands, such as dual-channel 16-bit, 1GSPS high-speed DAC.

Xinbaiwei's USB microcontrollers are widely used in portable video recorders, cameras, scanners, ATA interfaces, driving recorders, memory card readers, MPEG TV conversion, DSL modems and wireless networks. Some models such as USB2.0 and USB1.1 controllers are pin-compatible with certain international brands, which is convenient for customers to directly replace without changing the design.

After the Chinese New Year, there have been reports of chip price increases, especially for ST chips. Many companies cannot bear the rising costs.

Domestic substitution is an opportunity

It is said that the price increase will continue until next year.

The price of microchips has also increased and the delivery time has also increased.

No suitable replacement has been found yet. Some functions need to be verified by repeated trials.

Many prices have increased this year. I guess the agents are also increasing their prices.

Replace the current GD, which can be considered later

Yes, when replacing, some functions may have problems. I have encountered an SD card that did not work properly. Later, the problem was solved by increasing the clock. However, the power consumption changed after the increase, and the power consumption parameters of the replaced chip may not be the same.

Although it can be replaced as is, there will be many problems. I don’t know what problems the manufacturer has encountered from customer feedback, so generally speaking, they dare not replace it casually unless it is a new product.
