Description

The MCP98208 digital output temperature sensor is a

complete and NIST-traceable device and is verified

with equipment calibrated according to the

ISO/IEC-17025 standards. The MCP98208 device

converts temperature from -40°C and +125°C to a

digital word. This sensor provides an accuracy of

±0.2°C/±0.5°C (typical/maximum) from -20°C to

+60°C.

The MCP98208 device utilizes flexible, user-programmable

internal registers to configure the temperature

sensor's performance and response to high and low

temperature conditions, in order to provide system

design flexibility. Three dedicated alarms activate if the

temperature measurement exceeds the user-defined

temperature conditions. The internal registers allow

user-selectable settings, such as Shutdown or

Low-Power modes and the specification of temperature

Alert boundaries or Alert limits.

The MCP98208 has an internal 256-byte EEPROM

that can be used to store user-customizable data or

specific product information, critically important to

enhancing the application's system performance and

reliability. The EEPROM provides ultimate data storage

and protection capabilities with Permanent

Write-Protect and Software Reversible Write-Protect

options. This allows the system designer to store key

protect product information and protect it from hacking

or accidental data over-write. The EEPROM can be

used for high write endurance (>1M write cycles) for

frequent data storage and event capture capabilities.

This sensor uses an industry standard 2-wire,

I2C-compatible serial interface, allowing up to eight

devices to be controlled on a single serial bus.

The MCP98208 device is available in a space-saving

2 x 3 mm, 8-lead TDFN package.
