Notes:
- Stresses above those listed as "absolute maximum ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these conditions is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability.
- (1) Within these limits, clamping diodes are guarantee to be not conductive. Voltages outside these limits are authorised as long as injection current is kept within the specification.
This product contains devices to protect the inputs against damage due to high static voltages, however it is advisable to take normal precaution to avoid application of any voltage higher than the specified maximum rated voltages.
For proper operation it is recommended that VI and VO be higher than VSS and lower than VDD.Reliability is enhanced if unused inputs are connected to an appropriate logic voltage level (VDD or VSS).Power Considerations.The average chip-junction temperature, Tj, in Celsius can be obtained from:
Tj=TA + PD x RthJA
Where:TA = Ambient Temperature.
RthJA =Package thermal resistance (junction- to ambient).
PD = Pint + Pport.
Pint =IDD x VDD (chip internal power).
Pport =Port power dissipation (determined by the user).
DescriptionThe ST62T08C,T09C,T10C,T20C and ST62E20C 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.
The ST62E20C is the erasable EPROM version of the ST62T08C,T09C,T10C and T20C device, which may be used to emulate the ST62T08C,T09C,T10C and T20C device, as well as the respective ST6208C,09C,10C,20C ROM devices.
OTP and EPROM devices ST62T08C,T09C,T10C,T20C and ST62E20C are functionally identical. The ROM based versions offer the same functionality selecting as ROM options the options defined in the programmable option bytes of the OTP/EPROM versions.
OTP devices ST62T08C,T09C,T10C,T20C and ST62E20C offer all the advantages of user programmability at low cost, which make them the ideal choice in a wide range of applications where frequent code changes, multiple code versions or last minute programmability are required.
These compact low-cost devices ST62T08C,T09C,T10C,T20C and ST62E20C feature a Timer comprising an 8-bit counter and a 7-bit programmable prescaler,an 8-bit A/D Converter with up to 8 analog inputs and a Digital Watchdog timer, making them well suited for a wide range of automotive, appliance and industrial applications.
