One-time-programmable (OTP) memory
There are 32 bytes of OTP memory ideally suited for serial numbers, security keys, factory
calibration constants, or other permanent data constants. These OTP data bytes can be
programmed only one time through either the JTAG interface or by the CPU, and these
bytes can never be altered afterwards. As an option, a “lock bit” can be set by the JTAG
interface or the CPU which will block any further writing to the this OTP area. The “lock bit”
itself is also OTP. If the OTP array is unlocked, it is always possible to go back and write to
an OTP byte location that has not been previously written, but it is never possible to change
an OTP byte location if any one bit of that particular byte has been written before. The last
two OTP bytes (bytes 31 and 30) are reserved for the STR91xFA product ID and revision
level.
Product ID and revision level
OTP bytes 31 and 30 are programmed at ST factory before shipment and may be read by
firmware to determine the STR91xFA product type and silicon revision so it can optionally
take action based on the silicon on which it is running. In Rev H devices and 1MB/2MB Rev
A devices, byte 31 contains the major family identifier of "9" (for STR9) in the high-nibble
location and the minor family identifier in the low nibble location, which can be used to
determine the size of primary flash memory. In all devices, byte 30 contains the silicon
revision level indicator. See
devices and size of primary Flash memory. See
identification of silicon revisions.
