INTRODUCTION

The ST6215L/25L are low voltage mask programmed ROM version of ST62T15C,T25C OTP devices.

They offer the same functionality as OTP devices, selecting as ROM options the options defined in the programmable option byte of the OTP version, with the exception of the LVD Reset that is not available.
