GENERAL DESCRIPTION
The ST6294 microcontroller is member of the 8-bit HCMOS ST62xx family, a series of devices oriented to low-medium complexity applications. All ST62xx members are based on a building block approach: a common core is surrounded by a combination of onchip peripherals (macrocells). The macrocells of the ST6294 are: the Timer peripheral that includes an 8-bit counter with a 7-bit software programmable prescaler (Timer1), the 8bit Auto-reload Timer with 7 bit programmable prescaler (AR Timer), the 8-bit A/D Converter with up to 13 analog inputs (A/D inputs are alternate functions of I/O pins), the Digital Watchdog (DWD) and an 8-bit Serial synchronous Peripheral Interface (SPI). In addition, these devices offer 128 bytes of EEPROM for non volatile data storage. The ST6294 is a version of the ST6265 specifically tailored to be used in telephone set applications. The only difference is that a CKOUT pin is provided instead of the NMI pin. For this reason this datasheet only contains information relating to the differences to the ST6265, and thus should be read in conjunction with the ST6265 datasheet.
