• Manufacturer: ST Microelectronics

ST62T35B/E35B
INTRODUCTION (Cont’d)
OTP and EPROM devices are functionally identi-
cal. The ROM based versions offer the same func-
tionality selecting as ROM options the options de-
fined 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 programma-
bility are required.
These compact low-cost devices feature a Timer
comprising an 8-bit counter and a 7-bit program-
mable prescaler, an 16-bit Auto-Reload Timer,
with 2 input capture channels, EEPROM data ca-
pability, a serial synchronous port communication
interface (SPI), a serial asynchronous port inter-
face (UART), an 8-bit A/D Converter with 24 ana-
log inputs and a Digital Watchdog timer, making
them well suited for a wide range of automotive,
appliance and industrial applications.
