GENERAL DESCRIPTION
INTRODUCTION
The ST62T53B, ST62T60B, ST62T63B and ST62E60B devices are 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
■ DataEEPROM:64/128bytes(none onST62T53B)
■ User Programmable Options
■ 13 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
■ 6 I/O lines can sink up to 20mA 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
■ 8-bit A/D Converter with 7 analog inputs
■ 8-bit Synchronous Peripheral Interface (SPI)
■ On-chip Clock oscillator 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).
