5 / 59 page  5 MB89670R/670AR Series s DIFFERENCES AMONG PRODUCTS 1. Memory Size Before evaluating using the piggyback product, make sure of its differences from the product that will actually be used. Take particular care on the following points: • On the MB89P677A, the program area starts from address 8007H, while on the MB89677AR and MB89PV670A starts from 8000H. (On the MB89P677A, the option setting data can be read by reading the addresses “8000H” to “8006H”, while on the MB89677AR and MB89PV670A, addresses 8000H to 8006H could also be used as a program ROM. However, do not use these addresses in order to maintain compatibility of the MB89P677A.) • The stack area, etc., is set at the upper limit of the RAM. • The external area is used. 2. Current Consumption • In the case of the MB89PV670A, add the current consumed by the EPROM which is connected to the top socket. • When operated at low speed, the product with an OTPROM (one-time PROM) or an EPROM will consume more current than the product with a mask ROM. However, the current consumption in sleep/stop modes is the same. (For more information, see sections “s Electrical Characteristics” and “s Example Characteristics.”) 3. Mask Options Functions that can be selected as options and how to designate these options vary by the product. Before using options check section “s Mask Options.” Take particular care on the following point: • Options are fixed on the MB89PV670A. 4. Differences between the MB89670/670A and MB89670R/670AR Series • Memory access area Memory access area of both the MB89677A and MB89677AR is the same. The access are of the MB89673 is different from that of the MB89673R and MB89673AR respectively in the external bus mode. See below. Address Memory area MB89673 MB89673R/673AR 0000H to 007FH I/O area I/O area 0080H to 01FFH RAM area RAM area 0200H to 027FH External area Access prohibited 0280H to BFFFH External area C000H to DFFFH Access prohibited E000H to FFFFH ROM area ROM area |
