C8051T620/1/6/7 & C8051T320/1/2/3
15.1. Program Memory
The CIP-51 core has a 64 kB program memory space. The C8051T620/1/6/7 & C8051T320/1/2/3 imple-
ments up to 65535 bytes of this program memory space as in-system byte-programmable EPROM. Refer
to Table 2.1 on page 21 or Figure 15.1 for additional details on program memory size. Figure 15.3 shows
the program memory maps for C8051T620/1/6/7 & C8051T320/1/2/3 devices.
