Set the address of PROM programmer in the user ROM area. Fig. 57 Programming and testing of One Time PROM version Package 100PFB-A 100P6Q-A 100D0 Name of Programming Adapter PCA4738H-100A PCA4738G-100A PCA4738L-100A Table 12 Special programming adapter The PROM of the blank One Time PROM version is not tested or screened in the assembly process and following processes. To en- sure proper operation after programming, the procedure shown in Figure 57 is recommended to verify programming. Programming with PROM programmer Screening (Caution) (150 °C for 40 hours) Verification with PROM programmer Functional check in target device The screening temperature is far higher than the storage temperature. Never expose to 150 °C exceeding 100 hours. Caution : |
