PCA1487 - 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
PCA1487 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
