GENERAL DESCRIPTION
INTRODUCTION
The ST62T52C and ST62T62C devices is low cost members of the ST62xx 8-bit HCMOS family of microcontrollers, which is targeted at low to medium complexity applications. All ST62xx devices are based on a building block approach: a common core is surrounded by a number of on-chip peripherals.

■ 3.0 to 6.0V Supply Operating Range
■ 8 MHz Maximum Clock Frequency
■ -40 to +125°C Operating Temperature Range
■ Run, Wait and Stop Modes
■ 5 Interrupt Vectors
■ Look-up Table capability in Program Memory
■ Data Storage in Program Memory: User selectable size
■ Data RAM: 128 bytes
■ Data EEPROM: 64 bytes (none on ST62T52C)
■ User Programmable Options
■ 9 I/O pins, fully programmable as:
   – Input with pull-up resistor
   – Input without pull-up resistor
