Overview
T44C080-V Low-Current Microcontroller for Wireless Communication The T44C080-V is a member of Atmel Wireless & Microcontrollers’ family of 4-bit single-chip microcontrollers.
It contains ROM, RAM, parallel I/O ports, one 8-bit programmable multifunction timer/counter with modulator function, voltage supervisor, interval timer with watchdog function and a sophisticated on-chip clock generation with external clock input, integrated RC-, 32-kHz crystal- and 4-MHz crystal-oscillators.
Features / Benefits D Extended temperature range for very high temperature up to 125_C D Very low power consumption in active, power-down and sleep mode D 2-Kbyte ROM, 256 x 4-bit RAM D 12 bidirectional I/Os D Up to 6 external / internal interrupt sources D Multifunction timer/counter D Programmable system-clock with prescaler and five different clock sources D Wide supply voltage range (1.
8 to 6.
5 V) D Very low sleep current (< 1 µA) D Synchronous serial interface (2-wire, I2C, 3-wire) D Watchdog, POR and brown-out function D Voltage monitoring incl.
