OTP Memory Operation (C515C-8E only)
The C515C-8E contains a 64 Kbytes one-time programmable (OTP) program memory.
With the C515C-8E fast programming cycles are achieved (1 byte in 100
s). Also
several levels of OTP memory protection can be selected.
For programming of the device, the C515C-8E must be put into the programming mode.
This typically is done not in-system but in a special programming hardware. In the
programming mode the C515C-8E operates as a slave device similar as an EPROM
standalone memory device and must be controlled with address/data information,
control lines, and an external 11.5 V programming voltage. Figure 25 shows the pins of
the C515C-8E which are required for controlling of the OTP programming mode.
