The TC77-3.3MOATR is a serially accessible digital temperature sensor particularly suited for low cost and small form-factor applications. Temperature data is converted from the on-board thermal sensing element and made available at anytime as a 13-bit two's compliment digital word. Communication with the TC77-3.3MOATR is accomplished via an SPI/ Microwire compatible interface. The device features a 12-bit plus sign temperature resolution of 0.0625°C per LSB.The TC77-3.3MOATR offers a temperature accuracy of +/-1.0°C (max) over the temperature range of +25°C to +65°C. The SHUTDOWN bits in the Configuration register can be used to activate the low power Standby mode (0.1 uA typical). When operating, the TC77-3.3MOATR consumes only 250 µA (typ), 400 µA max. Small size, low installed cost and ease of use make the TC77-3.3MOATR an ideal choice for implementing thermal management in a variety of systems.
