ST6294 Datasheet (STMicroelectronics)

ST6294, 8-BIT HCMOS MCU

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).

* as the ST6265. NMI There is no external NMI pin in the ST6294. Although the ST6294 uses the standard ST62 core, which includes the NMI function. The user program therefore cannot place the ST62 in NMI mode. However, NMI mode is the default mode at power on or after a system reset generated by the wa
