ST62T65BM3 Datasheet PDF - ST Microelectronics

●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)
