Renesas' RX23E-B MCU features an enhanced built-in analog front end (AFE) specifically designed for industrial sensor devices. The RX23E-B series features a 24-bit delta-sigma a /D converter, offering enhanced high-speed and noise performance with a maximum data rate of 125kSPS. The noise of RMS has been reduced to approximately one-third of that of RX23E-A, allowing for precise and rapid measurement of strain, temperature, pressure, flow rate, current, voltage, etc. In addition, the RX23E-B integrates a 16-bit D/ a converter and a +/-10V high-voltage analog signal input circuit, minimizing the bill of materials (BOM) and floor space.

Application scenarios

R5F523E5BDFL is widely used in the following scenarios:

Industrial sensor equipment (such as load cells, force sensors, pressure gauges) ‌

Automatic control systems (such as PLC analog input modules, data acquisition systems)

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
