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

– Input with interrupt generation

– Open-drain or push-pull output

– Analog Input

■ 5 I/O lines can sink up to 30mA to drive LEDs or TRIACs directly

■ 8-bit Timer/Counter with 7-bit programmable prescaler

■ 8-bit Auto-reload Timer with 7-bit programmable prescaler (AR Timer)

■ Digital Watchdog

■ Oscillator Safe Guard

■ Low Voltage Detector for Safe Reset

■ 8-bit A/D Converter with 4 analog inputs

■ On-chip Clockoscillator can be driven by Quartz Crystal

Ceramic resonator or RC network

■ User configurable Power-on Reset

■ One external Non-Maskable Interrupt

■ ST626x-EMU2 Emulation and Development System

(connects to an MS-DOS PC via a parallel port)
