DS87C530/DS83C530 EPROM/ROM Microcontrollers with Real-Time Clock
DS83C530 ROM Verification
The DS83C530 memory contents can be verified using a standard EPROM programmer. The memory
address to be verified is placed on the pins shown in Figure 7, and the programming control pins are set to
the levels shown in Table 9. The data at that location is then asserted on port 0.
DS83C530 Signature
The Signature bytes identify the DS83C530 to EPROM programmers. This information is at
programming addresses 30h, 31h, and 60h. Because Mask ROM devices are not programmed in device
programmers, most designers will find little use for the feature, and it is included only for compatibility.
