The device programs the 64-bit and Sixteen 128-bit user-programmable OTP Register
data 16 bits at a time (see
page
Register’s address space causes a program error (SR.4 set). Attempting to program a
locked OTP Register causes a program error (SR.4 set) and a lock error (SR.1 set).
When programming the OTP bits in the OTP Registers for a Top Parameter Device, the
upper addresses A[Max:17] must also be driven high (V
packages.
Locking the OTP Registers
Each OTP Register can be locked by programming its respective lock bit in the Lock
Register. To lock an OTP Register, program the corresponding bit in the Lock Register by
issuing the Lock Register Program Setup command, followed by the desired Lock
Register data (see
physical addresses of the Lock Registers are 0x80 for register 0 and 0x89 for register 1.
These addresses are used when programming the Lock Registers (see
Identifier Information” on page
Bit 0 of Lock Register 0 is already programmed during the manufacturing process at
Numonyx factory, locking the lower half segment of the first 128-bit OTP Register. Bit 1
of Lock Register 0 can be programmed by user to the upper half segment of the first
128-bit OTP Register. When programming Bit 1 of Lock Register 0, all other bits need to
be left as ‘1’ such that the data programmed is 0xFFFD.
Lock Register 1 controls the locking of the upper sixteen 128-bit OTP Registers. Each
bit of Lock Register 1 corresponds to a specific 128-bit OTP Register; e.g.,
programming LR1.0 locks the corresponding OTP Register 1.
After being locked, the OTP Registers cannot be unlocked.
