Description
The Atmel® AT30TS00 combines a temperature sensor, programmable over-
temperature alarms, and a 2-wire I2C/SMBus compatible serial interface into single
compact packages specifically designed for DRAM memory module applications.
However, the AT30TS00 is ideal for many other applications. The AT30TS00
converts its die temperature into digital values using internal analog-to-digital
converters (ADCs). The result of the conversion is held in a temperature register
and is readable at any time through the serial interface. The temperature sensor
converts temperatures from -20°C to +125°C to a digital word and provides an
accuracy of ±1°C (max.) in the temperature range +75°C to +95°C. The temperature
sensor continuously monitors temperature and updates data in the temperature
register at least 8 times per second.
The AT30TS00 supports the industry standard 2-wire I2C/ SMBus serial Interface to
include a time out feature to help prevent system lock-ups.
The AT30TS00 has flexible user programmable internal registers to configure the
temperature sensor performance and response to over temperature conditions. The
device contains programmable high, low, and critical temperature limits. A dedicated
alarm output, EVENT, activates if the conversion result exceeds the value
programmed in the high temperature register. The device EVENT pin is configured
as active low and can be configured to operate as an interrupt or as a comparator
output.
The AT30TS00 features a shutdown mode that saves power by turning off
everything but the power-on reset and the 2-wire interface. The AT30TS00 EVENT
and SDA pins are open-drains and require connection of a suitable external pull-up
resistor.

2. Pin Descriptions
SERIAL CLOCK (SCL):
The SCL input is used to positive edge clock data into each device and
negative edge clock data out of each device.
SERIAL DATA (SDA):
The SDA pin is bidirectional for serial data transfer. This pin is open drain
driven and may be wire-ORed with any number of other open-drain or open
collector devices.
Device Addresses (A2, A1, A0): The A2, A1, and A0 pins are device address inputs that are hardwired (directly
to GND or to VCC) for compatibility with two-wire devices. If these pins are left
floating, the A2, A1, and A0 pins will be internally pulled to GND. However,
Atmel® recommends always connecting the address pins to a known state by
direct connection to ground or VCC.
Temperature Alert Output (EVENT): The EVENT Pin outputs a signal when the temperature goes beyond the user-
programmed temperature limit. The EVENT Pin is an open-drain output and can
be programmed as an interrupt, critical alarm or comparator mode.
