The 16F62X microcontroller

The 16F62X family of microcontrollers includes the two devices 16F627 and 16F628.

The 16F62X microcontrollers are flash devices and have 18 pins and data EEPROM just like the 16F84, but they have more functions. Notably there is an on board oscillator so an external crystal is not required. This frees up two pins for extra I/O. The 16F62X in fact can use 16 of its 18 pins as I/O.

Table 17.1 shows the specification of the 16F62X devices and the 16F84 for comparison.
