ATAR890 - Low-current Microcontroller

Download the ATAR890 datasheet PDF. This datasheet also covers the ATAR090 variant, as both devices belong to the same low-current microcontroller family and are provided as variant models within a single manufacturer datasheet.

Description

The ATAR090 and ATAR890 are members of Atmel’s family of 4-bit single-chip microcontrollers.

They offer the highest integration for IR and RF data communication and remote-control.

The ATAR090 and ATAR890 are suitable for the transmitter side.

Features

  • 2-Kbyte ROM, 256 × 4-bit RAM 12 Bi-directional I/Os Up to 6 External/Internal Interrupt Sources Multifunction Timer/Counter with.
  • IR Remote Control Carrier Generator.
  • Bi-phase-, Manchester- and Pulse-width Modulator and Demodulator Programmable System Clock with Prescaler and Five Different Clock Sources Wide Supply-voltage Range (1.8 V to 6.5 V) Very Low Slee.
