8583T - PCF8583T

Description

The PCF8583 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 bidirectional I2C-bus.

The built-in word address register is incremented automatically after each written or read data byte.

Features

I2C-bus interface operating supply voltage: 2.5 V to 6 V.
Clock operating supply voltage 1.0 V to 6.0 V at 0 °C to +70 °C.
240 × 8-bit low-voltage RAM.
Data retention voltage: 1.0 V to 6.0 V.

PCF8583 Clock and calendar with 240 x 8-bit RAM Rev. 06 — 6 October 2010 Product data sheet 1. General description The PCF8583 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 bidirectional 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 32.768 kHz oscillator circuit and the first 8 bytes 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.
