15 OTP PROGRAMMING

The programming of the PCD3755x and PCD3756x OTPs

is based on the OM4260 programmer (Ceibo MP-51),

available from Philips. The OM4260 works in conjunction

with various adapters supporting the different package

types available as listed in Table 25.

The low-voltage OTP program memory used is of

Anti-Fuse-PROM type and can not be erased after

programming.

Thus, the complete OTP memory cannot be tested by the

factory, but only partially via a special test array.

The average expected yield is 97%.

Detailed information on the OTP programming is available

in the

“PCD3755x Application Note”, which is available via

your Philips Sales office.

Note

1. As the OM5037 is only a socket converter, the OM5007 is also needed to program the PCD3755x/56x in the LQFP32

package.
