Note 1:
Typical values are T
A
= 25°C and nominal supply voltage (5V).
Note 2:
This parameter is periodically sampled and not 100% tested.
Note 3:
The "L" and "LZ" versions can be operated in the 2.5V to 5.5V V
CC
range. However the I
SB
values for L and LZ are applicable only when V
CC
is in the 2.5V to 4.5V range.

Note 4:
The write cycle time (t
WR
) is the time from a valid stop condition of a write sequence to the end of the internal erase/program cycle. During the write cycle,
the FM24C64 bus interface circuits are disabled, SDA is allowed to remain high per the bus-level pull-up resistor, and the device does not respond to its slave
目前医疗监护中无法动态掌握患者信息，一旦患者病情恶化，无法在第一时间实施抢救，对数据信息维护效率低。 文中首先阐述了蓝牙技术及其在医疗监护中应用的可行性，然后设计了系统框架，给出了具体功能，BlueTooth Wireless Communication Technology Application in Medical Monitoring包括数据采集和语音报警，最后对蓝牙信号在传输...[详细]
