Code Mem Stor
The most obvious difference between the C8051F34A and the C8051T62x/T32x devices is the code memory storage technology. On the C8051F34A device, Flash memory is used, while on the C8051T62x and C8051T32x devices, a Byte-programmable EPROM code memory architecture is used. EPROM memory can be programmed one Byte at a time but cannot be erased. The impact of code storage technology on the development of T62x/T32x firmware is minimal. When developing firmware for the C8051T62x or C8051T32x on the C8051F34A or porting an existing design from any C8051F34x device, ensure that there are no firmware routines intended to erase areas of code memory, as they will not have any effect on the C8051T62x or C8051T32x. Firmware can write to code memory on the C8051T62x and C8051T32x using in-application programming; however, each bit can only be cleared once and can never be reset.
