DS3231详细介绍(⾮芯⽚⼿册)年误差⼩于1分钟⾼精度时钟DS3231的设计及应⽤深圳市凌雁电⼦有限公司[1].前⾔在许多单⽚机的测控系统和家⽤电器中都含有时钟显⽰部分,最廉价的是直接使⽤单⽚机中的定时器,辅以⼀定的中断服务程序,构成时钟显⽰部分,这种⽅式是⼏乎不需要增加新的硬件即可实现,缺点是计时误差⼤,同时电源掉电不能保持时钟继续运⾏。
在相对要求较⾼的场合,则使⽤廉价的时钟芯⽚(如DS1302等等)辅以备⽤电池,计时精度略⾼,可满⾜⼀般的要求。
在这篇⽂章中,我们重点介绍⾼精度时钟电路DS3231的设计和应⽤。
在DS1302普及型时钟芯⽚,晶体均需外置,由于晶体的离散性,很难选择到精度很⾼的器件,同时也没有温度补偿电路,不同的温度环境下,晶体的特性也在变化,直接影响着时钟的振荡频率,较⼤的误差在所在所难免。
⽽DS3231⾼精度时钟芯⽚,将晶体和温度补偿均集成在芯⽚中,为提⾼计时精度提供了可能,实册证明,使⽤DS3231时钟芯⽚,误差可做到⼀年⼩于⼀分钟,甚⾄部分显⽰器误差可⼩于20秒/⼀年。
这对有相对精确时钟要求的应⽤场合是个理想的选择。
[2].DS3231时钟芯⽚结构原理DS3231是⼀款⾼精度I2C实时时钟(RTC)器件,具有集成的温度补偿晶体振荡器(TCXO)。
该器件包含电池输⼊端,断开主电源时仍可保持精确计时。
集成的晶体振荡器可提⾼器件的长期精确度。
DS3231的寄存器能保存秒、分、时、星期、⽇期、⽉、年和闹钟设置等信息。
少于31天的⽉份,可⾃动调整⽉末⽇期,包括闰年补偿。
时钟的⼯作格式为24⼩时或带AM/PM指⽰的12⼩时格式。
DS3231提供两个可编程⽇历闹钟和⼀路可编程⽅波输出。
DS3231与单⽚机通过I2C双向串⾏总线传输地址与数据。
下图为DS3231典型应⽤电路,图中可看出,DS3231⼏乎不需要外部元件。
[3].DS3231时钟芯⽚结构如图1所⽰,DS3231的主要组成部分有8个模块,划分为4个功能组:TCXO、电源控制、按钮复位和RTC。

The APLL has two modes: the lock mode and the bypass mode.In the lock mode, the input clock is multiplied and/or divided, and in the bypass mode, the input clock is divided only. At device power-up, the bypass mode is selected.To configure the APLL, use the USB analog PLL control register, USBAPLL (see Figure 7 and Table 4). This register is at address 1F00h in the I/O space of a TMS320VC5507/5509A device. The following paragraphs describe the functionality provided by the bits in USBAPLL.The MODE bit selects either the lock mode or the bypass mode. In the lock mode, the APLL requires the use of an internal voltage-controlled oscillator (VCO). The VCO is turned on by either the MODE bit or the ON bit, and the VCO is turned off if both of these bits are 0.The MULT field of USBAPLL selects a multiplication factor K. In the bypass mode, K determines how the input clock (CLKIN) is divided to produce the USB module clock. In the lock mode, K is used in conjunction with the DIV bit to determine the relative frequency of the USB module clock. Table 15 summarizes all the options. Remember that the USB module requires a frequency of 48 MHz.The COUNT field is a down-counter used to track the APLL lock time. The APLL requires approximately 350 μs to lock, and COUNT provides a means to track the lock time in terms of the input clock (CLKIN). As soon as the lock mode is turned on (that is, as soon as the MODE bit changes from 0 to 1), the phase-locking sequence begins and COUNT decremented by 1 every 16 CLKIN cycles. When COUNT reaches 0, the STAT bit is set. To make sure the countdown time matches the lock time, use the following equation whenloading COUNT:Figure 7. USB Analog PLL Control Register (USBAPLL)Legend: R = Read; W = Write; -n = Value after reset↑This reserved bit must be kept 0 for proper operation of the USB clock generator.Table 4. Bits of the USB Analog PLL Control Register (USBAPLL)15−12 MULT PLL multiply value. MULT + 1 is the multiply factor K. Table5shows how this factor affects the operation of the APLL.0000b K= 10001b K = 20010b K = 30011b K = 40100b K = 50101b K = 60110b K = 70111b K = 81000b K = 91001b K = 101010b K = 111011b K = 121100b K = 131101b K = 141110b K = 151111b K = 16Introduction to the USB ModuleTable 5. APLL Options for the USB Module Clock Frequency↑ K = MULT + 1↕ The USB clock frequency must be 48 MHz for proper operation of the USB module.2.4.4 Idle Mode ConsiderationsIdling the USB module does not idle the USB clock generator. Doing this simplyprevents the USB module clock signal from driving the USB module.Both the DSP clock generator and the USB clock generator are part of the CLKGEN idledomain. If the IDLE instruction deactivates the CLKGENdomain, both clock generators stop running.3 USB Buffer Manager (UBM)When data is to be moved to or from the buffer RAM, the UBM accesses oneof the following endpoint buffers in the buffer RAM:Each general-purpose endpoint can be configured to have a single buffer (X)or a double buffer (two buffers, X and Y). This is controlled by the double buffermode (DBUF) bit in USBxCNFn. If there are two buffers, the UBM keeps trackof which buffer to use. If the endpoint is in the non-isochronous mode, the UBMuses the X buffer for a DATA0 packet and the Y buffer for a DATA1 packet.Each of the endpoint buffers is associated with a programmable count registerof the following format:The NAK bit corresponds to the negative acknowledgement (NAK) of the USBprotocol. If the NAK bit is set (NAK = 1), the SIE sends a NAK in response toa host request to that particular endpoint. The UBM does not access the bufferuntil NAK is cleared (NAK = 0).译文:2.4.3 APLL 操作(只有TMS320VC5507/5509A设备)在TMS320VC5507/5509A设备中,如果PLLSEL= 1在USBPLLSEL中则APLL被选择。

Thisis automatically the case if the device does not stretch the low period of the SCL signal. If such a device does stretch the low period of the SCL signal, it must output the next data bit to the SDA line t R(MAX)+t SU:DAT = 1000 + 250 = 1250ns before the SCL line is released.Note 10:C B —total capacitance of one bus line in pF.Note 11:The parameter t OSF is the period of time the oscillator must be stopped for the OSF flag to be set over the voltage range of0.0V ≤V CC ≤V CC(MAX)and 2.3V ≤V BAT ≤3.4V.Note 12:This delay applies only if the oscillator is enabled and running.
