Since the advent of smart door locks, with the maturity of related technologies and the change of daily consumption concepts and habits, consumer acceptance has gradually increased. Whether a smart door lock is outstanding, the core lies in the lock board program, and the key to the quality of the lock board program lies in whether it has a powerful master control chip.
Today, according to the bydir semiconductor public account news, following the launch of the first integrated touch, RFID smart lock main control MCU (BF5823AM48) in China in August 2020, BYD Semiconductor recently integrated product advantages, multi-dimensional upgrades, and successfully developed a higher integration, higher configuration, higher positioning "four-in-one" MCU - BF5885AM64.
More integrated "four-in-one" MCUs – BF5885AM64
The "four-in-one" MCU chip integrates and implements four major functions: MCU master control, RFID smart card detection, Touch-Key touch buttons and voice playback. Compared with the previous generation, BF5885AM64 has improved its parameters, performance and application-side functions, and has added the special function of voice playback, which can meet the needs of network interaction and background thread processing, and is oriented to higher-end customer groups.
Launched at the same time as BF5885AM64 is a 120 multifunctional fingerprint module BF5031A0, with pixels of 120*120. It integrates BYD Semiconductor 120*120 capacitive fingerprint sensor, fingerprint MCU and fingerprint algorithm, and has both AES128/SM4 security algorithm and embedded dual-mode algorithm, which is mainly used in the field of fingerprint door lock, which can be tailored for different customers. The product has the following characteristics: 1. Ultra-low power consumption, power consumption
120 fingerprint module: BF5031A0
"Four-in-one" MCU chip + 120 fingerprint module to create a one-stop solution for smart door locks. Compared with the mainstream smart lock board solution in the market, the advantages of THIS set of smart door lock solutions of BYD Semiconductor are more prominent:

▌The solution is highly integrated
The "four-in-one" MCU chip can directly integrate a variety of functions such as touch function, RFID card function and voice playback with only one chip, and with BYD Semiconductor fingerprint module, the overall solution is more cost-effective.
▌ Develop application experience is better
As long as you debug a "four-in-one" MCU chip, you can complete the function debugging of the main control + 3 peripherals, which greatly shortens the overall software and hardware solution development cycle. In addition, in BYD Semiconductor's complete and reliable chip hardware design scheme and software supporting debugging data, there are complete SDK, hardware recommendation circuits, demo DEMO circuits and source code, customers can quickly complete functional debugging, convenient and efficient.
▌ Lower static power consumption
Based on the highly integrated and low-power design, the BF5885AM64 has a quiescent power consumption of less than 30uA (touch button @4Hz, RFID@2Hz), which is better than the industry average and lower than the previous generation.
▌ The overall configuration is more powerful
BF5885AM64 has a high-performance core Cortex-M0, the highest operating frequency of 48MHz, can work stably in the environment of -45 °C ~ +125 °C, I/O port electrostatic test can pass ±8KV, has passed many rounds of rigorous reliability testing, to achieve high quality assurance. Not only that, the overall solution has a streamlined application circuit, rich IO resources, and low Bom cost, which is conducive to cost control. Before and after the establishment of the project, BYD Semiconductor's complete scientific research team continuously summarized and learned from past development experience, worked together to overcome a number of technical problems, and had strong technical support strength.
