BCM89071 Data Sheet
One-Time Programmable Memory
One-Time Programmable Memory
The BCM89071 includes a One-Time Programmable (OTP) memory, allowing manufacturing customization and
avoiding the need for an on-board NVRAM.If customization is not required, then the OTP does not need to be
programmed. Whether the OTP is programmed or not, it is disabled after the boot process completes to save
power.
The OTP size is 128 bytes.
The OTP is designed to store a minimal amount of information. Aside from OTP data, most user configuration
information will be downloaded into RAM after the BCM89071 boots up and is ready for host transport
communication. The OTP contents are limited to:
• Parameters required prior to downloading user configuration to RAM.
• Parameters unique to a customer design.
