The MCP79512 SPI RTCC is highly integrated with memory and advanced features normally found in higher priced devices. By starting with a basic real-time clock, digital trimming was added for higher accuracy, a battery switchover for backup power, a timestamp to log power failures and three types of memory, which includes SRAM, EEPROM and a unique ID in a locked section of EEPROM. This ID is preprogrammed with a 64-bit MAC Address, but it can also be ordered blank for the end user to program.
General purpose SPI RTCC with features that target low power, security & communications applications.Low Power Operation ? ? -? ? VCC Min = 1.8V ? ? -? ?Icc
Low Backup Power ? ? -? ? VBAT Min = 1.3V ? ? -? ? Ibat
Automatic Battery Switchover with Timestamp ? ? -? ? VCC to VBAT ? ? ? (VCC Lost) ? ? -? ? VBAT to VCC ? ? ? (VCC Restored)
Dual configurable alarms with a 0.01 sec count on one alarm? ? -? ? IRQ ? ? ? (VCC or VBAT)
Clock Out frequencies: 32.768, 8.192 & 4.096 KHz and 1 Hz
Digital Trimming Range from -255 to + 255 ppm in 1 ppm steps ? ? -? ? Adjusts up to 22 seconds/day
EEPROM has 8 Bytes/Page with Block Sector write protection? ? -? ? Protect:?? None, 1/4, 1/2 or all of array
Factory standard MAC address programming or custom ID available

相較于內(nèi)含MCU的混合式半數(shù)位電源控制的LEDDriver,MCP1633在價(jià)格上相對低廉許多,而使用上也和DEPA系列的MCP19xxxLowsideMOSFETdriver也非常類似,可以
存儲,一個(gè)簡單的詞匯,卻保存了對于我們而言十分重要的數(shù)據(jù)。往期存儲相關(guān)文章中,小編對對象存儲、文件存儲、云存儲均有所闡述。為增加大家對存儲的認(rèn)識,本文將對MCP存儲器以及MCP存儲器的應(yīng)用發(fā)展予以
