R H1344 Copyright © 2004, EM Microelectronic-Marin SA 4 www.emmicroelectronic.com Functional Description Oscillator and Frequency Divider The quartz oscillator consists of an inverter, internal feedback resistance to bias the input and integrated capacitors. The values of the integrated capacitors are selectable by metal mask. The oscillator is designed for 32768Hz. Motor Drive Output The circuit contains two push-pull output buffers for driving bipolar stepping motors. Between two pulses, both P- channel transistor of the other buffer are conducting. The outputs are protected against i nductive voltage spikes with diodes to both supply pins. Both the motor pulse period and motor pulse width are programmable by metal mask over a wide range of values (see page 6 for available options). Alarm Output The alarm is activated by connecting ALARM IN to VSS and is deactivated by opening the connection. A metal mask option is available to program a continuous activation of the alarm output. The alarm output driver contains a push-pull output buffer to drive an external sound source by means of an external bipolar transistor. A metal mask option is available to allow the use of NPN or PNP-transistors. The tone frequency, modulation frequency, modulation frequency and cycle time (ON/OFF time) are metal mask selectable. Test Mode The ALARM IN pin fulfills three functions: a) For normal operation, the ALARM IN pin is left open. The circuit provides a square wave signal of 1024Hz, which can be used to tune the oscillator. b) If the pin is connected to V SS, the alarm signal is provided at pin 6. c) If the ALARM IN pin is connected to V DD, all output frequencies are increased by a factor of 64, the alarm modulation of fA1 = 8Hz and fA = 2kHz are suppressed.
