Code Memory Storage

 Flash memory used on C8051F34A family

 Byte-programmable EPROM code memory on the C8051T62x/32x

families

 When pre-fetch engine is enabled (default) timing is similar to flash devices

 Porting considerations

• Insure no firmware routines exist to erase code memory

• In application firmware can write to memory, but only once

 Add a 4.7 uF capacitor to enable programming the V

pin to ground

• C8051T62x and C8051T32x devices
