Shenzhen Mingjiada Electronics Co., Ltd. is an electronic component inventory recycler specialising in providing professional, efficient, and secure electronic component recycling services to global customers. With its professional technical team, efficient evaluation system, and global logistics network, the company can quickly help customers reduce inventory, minimise storage costs, and recover funds.

Recycled products include: 5G chips, new energy ICs, IoT ICs, Bluetooth ICs, vehicle networking ICs, automotive-grade ICs, communication ICs, artificial intelligence ICs, memory ICs, sensor ICs, microcontroller ICs, transceiver ICs, Ethernet ICs, WiFi chips, wireless communication modules, connectors, and a range of other products.

Recycling process:

1. Sort your excess IC/module inventory, identifying model numbers, brands, production dates, and quantities.

2. Send the inventory list via fax or email to our evaluation team.

3. Wait for a purchase quote from our professionals. Once an agreement is reached, both parties will negotiate the specific transaction details for delivery.

4. The company only recycles products sourced from official channels, such as distributors, traders, and end-user factories, and does not accept products from non-official channels.

【Core Value of the SPI-to-I2C Bridge】

Silicon Labs' CP2120 is a quintessential SPI-to-I2C bridge and GPIO port expander. The evaluation kit CP2120EK fully demonstrates this device's fixed functionality.

From a technical specification perspective, the CP2120 operates via a 4-wire SPI bus at frequencies up to 1MHz, whilst I²C data transfer rates can be configured up to 400kHz. These performance parameters offer a distinct advantage over comparable products, particularly when handling high-speed data transmission requirements.

The bridge features a highly compact design incorporating 255-byte receive and transmit buffers. This ensures stable communication performance even during data bursts, preventing data loss.

For power management, the CP2120 supports operating voltages from 2.4V to 3.6V while providing 5V-tolerant I/O pins. This design enhances the device's compatibility and applicability.

【Widespread Applications of USB Bridges】

Silicon Labs offers multiple USB bridge solutions, with the CP2102C series being a representative example. These products are suitable for diverse scenarios requiring USB communication.

Taking the CP2102C as an illustration, it highly integrates a USB-to-UART bridge controller within a compact 4mm x 4mm package, significantly simplifying design complexity and reducing material costs.

This series offers multiple packaging options, such as QFN-20, QFN-24, and QFN-28, to accommodate diverse design requirements.

Notably, these USB bridges excel in power consumption management. For instance, the CP2102C exhibits a USB suspend current of merely 195 microamperes. This low-power characteristic confers significant advantages in battery-powered applications during standby operation.

Whether deployed in POS terminals, diagnostic equipment, or USB dongles, Silicon Labs' USB bridges emerge as engineers' preferred solution, featuring UART baud rates up to 3 Mbps and full USB 2.0 compatibility.

【Specialised Capabilities of Digital Audio Bridges】

In the digital audio domain, Silicon Labs' CP2615 exemplifies the technological standard for USB-to-I2S digital audio bridges. Optimised for audio applications and compliant with the USB Audio 1.0 specification, this device transmits audio data from USB to I2S without requiring any code development.

Regarding technical specifications, the CP2615 supports 48 kHz sampling rates and 16-bit/24-bit stereo digital audio processing capabilities. This audio quality fully meets the requirements of most consumer and professional audio equipment.

The audio bridge features an exceptionally compact QFN-32 package measuring just 5 mm x 5 mm. Its diminutive form factor enables seamless integration into compact audio devices such as USB speakers, headphones, and point-of-sale terminals.

For power management, the CP2615 incorporates an on-chip voltage regulator operating within a 2.7V to 3.6V range, with a typical operating current of 20.2mA. This power design ensures stable operation under varied supply conditions.
