10 / 361 page  7470/7471/7477/7478 GROUP USER’S MANUAL HARDWARE 1.2 Group expansion 1-3 1.2 Group expansion The 7470/7471/7477/7478 group develops with the M37470M2-XXXSP as the base chip in the 7470 series. The classification of the 7470 series is as follows. 7470 series 7470 group 7471 group 7477 group 7478 group 7480 group** 7481 group** The 7470/7471/7477/7478 group permits group expansion as shown in Figure 1.2.1. This group expansion is all performed only by differences in memory type and capacity and the number of ports. This allows the user to select optimum elements according to the user's system. The 7470/7471/7477/7478 group supports the following in addition to the mask ROM version. (1) Support of One Time PROM version The One Time PROM version is a programmable microcomputer and can perform a one-time write operation to the built-in programmable ROM (PROM). For the details, refer to “1.19 Built-in PROM version.” (2) Support of EPROM version (with window) The built-in EPROM version is a programmable microcomputer with window and can perform write and erase operations to the built-in EPROM. For the details, refer to “1.19 Built-in PROM version.” (3) Support of emulator MCU The emulator MCU is a microcomputer designed for program development which facilitates program development and is an optimum element for system evaluation. For the details, refer to“1.20 Emulator MCU.” Table 1.2.1 shows the products which the 7470/7471/7477/7478 group supports. In this manual, when multiple models are described collectively, their names are arranged by putting “/” among them for separation. 7470 group, 7471 group → 7470/7471 group 7477 group, 7478 group → 7477/7478 group 7470 group, 7477 group → 7470/7477 group 7471 group, 7478 group → 7471/7478 group **:Under development |
