1.1 INTRODUCTION
●The ST62T55B, ST62T65B and ST62E65B 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
●■ Data EEPROM: 128 bytes (none on ST62T55B)
●■ User Programmable Options
●■ 21 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
●■ 8 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 13 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)
