APPLICATION NOTE
SELECTING BETWEEN ROM, FASTROM AND OTP
FOR A MICROCONTROLLER
by Microcontroller Division Applications
INTRODUCTION
A customer who develops an MCU-based application needs various levels of flexibility in order
to perform code modifications at different times in the life cycle of the product (these levels are
explained on the next page). To satisfy these requirements, STMicroelectronics supports sev-
eral device types within two main groups of microcontroller product families:
– EPROM, OTP, FASTROM and ROM microcontroller families
– Flash, FASTROM and ROM microcontroller families
This Application Note discusses the first group of families. For information on the second
group, refer to Application Note AN1068.
