The device can also be programmed in standard programmers. The array matrix organisation allows each block to be erased and reprogrammed without affecting other blocks. Blocks can be protected against programing and erase on programming equipment, and temporarily unprotected to make changes in the application. Each block can be programmed and erased over 100,000 cycles. July 1998 PDIP32 (P) PLCC32 (K) TSOP32 (N) 8 x 20mm Figure 1.
