The N25Q064 has 64 one-time-programmable bytes (OTP bytes) that can be read and
programmed using two dedicated instructions, Read OTP (ROTP) and Program OTP
(POTP), respectively. These 64 bytes can be permanently locked by a particular Program
OTP (POTP) sequence. Once they have been locked, they become read-only and this state
cannot be reversed.
Many different N25Q064 configurations are available, please refer to the ordering scheme
page for the possibilities. Additional features are available as security options (The Security
features are described in a dedicated Application Note). Please contact your nearest
Numonyx Sales office for more information.
