OTP Memory Operation (C505A-4E and C505CA-4E only)
The C505A-4E/C505CA-4E contains a 32K byte one-time programmable (OTP) program memory.
With the C505A-4E/C505CA-4E fast programming cycles are achieved (1 byte in 100
sec). Also
several levels of OTP memory protection can be selected.
For programming of the device, the C505A-4E/C505CA-4E 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 C505A-4E/C505CA-4E 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 11.5V programming voltage. Figure 26 shows the pins of the C505A-4E/C505CA-4E
which are required for controlling of the OTP programming mode.
