ST62T28C General Description

The ST62T28C and ST62E28C devices are low cost members of the ST62xx 8-bit HCMOS family of microcontrollers, which are 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 onchip peripherals.

The ST62E28C is the erasable EPROM version of the ST62T28C device, which may be used to emulate the ST62T28C device, as well as the respective ST6228C ROM devices. OTP and EPROM devices are functionally identical.

The ROM based versions offer the same functionality selecting as ROM options the options defined in the programmable option byte of the OTP/ EPROM versions.OTP devices 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 feature a Timer comprising an 8-bit counter and a 7-bit programmable prescaler, an 8-bit Auto-Reload Timer, with 1 input capture channel, capability, a serial asynchronous port interface (UART), a synchronous serial port interface, an 8-bit A/D Converter with 12 analog inputs and a Digital Watchdog timer, making them well suited for a wide range of automo-

ST62T28C Maximum Ratings

Symbol	Parameter	Value	Unit
V_DD	Supply Voltage	-0.3 to 7.0	V
V_I	Input Voltage	VSS - 0.3 to V_DD + 0.3(1)	V
V_O	Output Voltage	VSS - 0.3 to V_DD + 0.3(1)	V
IV_DD	Total Current into VDD (source)	80	mA
IV_SS	Total Current out of VSS (sink)	100	mA
T_J	Junction Temperature	150	°C
T_STG	Storage Temperature	-60 to 150	°C

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.
