(Summary description)In recent years, the upgrading of household consumption, such as greening, intelligence, and customization, has gradually become a new trend in home consumption. Among them, smart door locks have become essential for home use, with an increasing level of intelligence. They can not only achieve the most basic unlocking methods such as fingerprints, passwords, and facial recognition, but also more intelligent unlocking methods such as gesture recognition and voice recognition. Although a series of intelligent functions are highly recognized by the market, stability issues such as system crashes and disconnections, high fingerprint recognition error rates, and the need for frequent battery replacement for door locks still plague major smart lock enterprises. The core component of intelligent door locks is the MCU chip, so the most direct solution to optimize the system and battery life is to choose a high reliability and low-power MCU solution. Physical image of a certain brand's fingerprint lock (with built-in Hangshun MCU solution) As mentioned above, a certain brand of intelligent fingerprint lock with built-in Hangshun HK32C030 family solution is powered by 4 batteries, which have extremely low power consumption in standby mode, greatly extending the battery's usage time. In terms of functionality, it supports multiple unlocking modes such as fingerprint unlocking, password unlocking, RF card swiping unlocking, and supports voice prompts, voice anti-theft alarms, and third-generation optical fingerprint recognition. Block diagram of intelligent door lock system (HK32C030 family application) In the intelligent lock system, HK32C030 is mainly responsible for controlling and managing various sensors, actuators, and communication modules. For example, it can unlock the door lock by reading the RF card or fingerprint recognition, and convey the unlocking information to the user through voice broadcasting and OLED display modules. Compared with other MCU products, HK32C030 not only has excellent performance and low power consumption characteristics, but also effectively enhances the battery life of the intelligent lock, ensuring long-term operation of the system; It can also provide rich peripheral interfaces and powerful processing capabilities, which can meet the high requirements of intelligent lock systems. HK32C030 Family Product Features CPU core: ARM Cortex-M0, with a maximum clock frequency of 64 MHz Supports up to 64 KB of Flash (including 61Kbyte main Flash area and 3Kbyte Bootloader area that can be configured as main Flash area), 10 KB SRAM Data communication interface 3-way UART: It can generate different baud rates through its built-in baud rate generator, and also supports single line half duplex communication, multi processor communication, and other functions. 2-way high-speed SPI: supports 4 to 16 bit programmable data frames with a multiplexed I2S interface. 2-way I2C: Supports ultra fast mode (1Mbit/s), SMBus, and PMbus. In Stop mode, supports data reception and wake-up. Timer and PWM generator 1 16 bit advanced timer (TIM1 has 4 PWM outputs, including 3 with dead zone complementary outputs and braking function) 5 16 bit and 1 32-bit universal timers (TIM2/TIM3/TIM14/TIM15/TIM16/TIM17) 1 16 bit basic timer (TIM6) On chip analog circuit 1 12 bit SAR ADC (up to 23 analog signal input channels) maximum converter frequency: 1.14 MSPS 9-bit resolution temperature sensor with a temperature acquisition range of -40 ° C to+105 ° C Supports RTC with alarm function Working voltage range: VDD: 2.6V~5.5V Working temperature range: -40 ° C~+105 ° C Reliability: Tested at HBM6500V/CDM2000V/LU800mA level. The HK32C030 series MCU is equipped with corresponding development boards for engineers to verify its functionality, and software provides application routines for commonly used functions for engineers to design and reference. At present, many mainstream smart door lock companies have chosen the HK32C030 series of Hangshun chips for product design and mass production. In order to achieve a fast and effective product development process for the client, we are committed to updating and improving the ecosystem while conducting product research and development.
