AT8593数据手册Analogtek中文资料规格书

描述 Description

The AT8593 is a CMOS clock/calendar circuit, optimized for low power consumption. Addresses and data are transferred serially via the two-line bidirectional I2C-bus.\r
\r
The built-in word address register is incremented automatically after each written or read data byte.\r
\r
The built-in 32.768kHz oscillator circuit and the first 8 bytes of RAM are used for the clock/calendar and counter functions. The next 8 bytes may be programmed as alarm registers or used as free RAM space
