Nxp (PCF8583T/5,518) Calendar, Clock IC, I2C, 2.5 V to 6 V supply, SOIC-8

Calendar, Clock IC, Format (YYYY:MM:WK:DD:hh:mm:ss/Binary), I2C, 2.5 V to 6 V supply, SOIC-8 Product Overview The PCF8583T/5,518 is a Clock and Calendar Chip, based on a 2048-bit static CMOS1 RAM organized as 256 words by 8-bits. Addresses and data are transferred serially via the two-line bi-directional I²C-bus. The built-in word address register is incremented automatically after each written or read data byte. Address pin A0 is used for programming the hardware address, allowing the connection of two devices to the bus without additional hardware. The built-in 32.768kHz oscillator circuit and the first 8bytes of the RAM are used for the clock, calendar and counter functions. The next 8 bytes can be programmed as alarm registers or used as free RAM space. The remaining 240 bytes are free RAM locations. Clock function with 4-year calendar Universal timer with alarm and overflow indication Automatic word address incrementing Programmable alarm, timer and interrupt function Applications Communications & Networking, Signal Processing Product Information Date Format: YYYY:MM:WK:DD:Hr:Min:Secs Clock Format: Binary Clock IC Type: Calendar, Clock Supply Voltage Min: 2.5V Supply Voltage Max: 6V Clock IC Case Style: SOIC No. of Pins: 8Pins IC Interface Type: I2C Operating Temperature Min: -40°C Operating Temperature Max: 85°C MSL: MSL 2 - 1 year
