PCA1485 Datasheet (NXP)

PCA1485, CMOS

chip with bumps on tape chip with bumps on tape chip on foil chip on foil GENERAL DESCRIPTION PCA148x series * No loss of motor steps possible because of on-chip detection of the induced motor voltage * Indication for battery end-of-life * Stop function for accurate timing

PCA1485 Features

* 32 kHz oscillator, amplitude regulated with excellent frequency stability

* High immunity of the oscillator to leakage currents

* Time calibration electrically programmable and reprogrammable (via EEPROM)

* A quartz crystal is the only external component required
