These microcomputers support the 7900 Series instruction set, which are enhanced and expanded instruction set and are up- per-compatible with the 7700/7751 Series instruction set. The CPU of these microcomputers is a 16-bit parallel processor that can also be switched to perform 8-bit parallel processing. Also, the bus interface unit of these microcomputers enhances the memory access efficiency to execute instructions fast. Therefore, these mi- crocomputers are suitable for office, business, and industrial equip- ment controller that require high-speed processing of large data. For the internal flash memory, single-power-supply programming and erasure, using a PROM programmer or the control by the cen- tral processing unit (CPU), is supported. Also, each of these micro- computers has the memory area dedicated for storing a certain software which controls programming and erasure (reprogramming control software). Therefore, on these microcomputers, the program can easily be changed even after they are mounted on the board. • Programming/Erase control by software command • Maximum number of reprograms ............................................ 100 APPLICATION Control devices for personal computer peripheral equipment such as CD-ROM drives, DVD-ROM drives, hard disk drives, high density FDD, printers DISTINCTIVE FEATURES <Microcomputer mode> • Number of basic machine instructions .................................... 203 • Memory [M37902FCCHP] Flash memory (User ROM area) ................................. 120DKabtyateSsheet4U.com RAM ............................................................................. 4096 bytes [M37902FGCHP] Flash memory (User ROM area) ................................. 248 Kbytes RAM ............................................................................. 6144 bytes [M37902FJCHP] Flash memory (User ROM area) ................................. 498 Kbytes RAM ........................................................................... 12288 bytes [All of the above computers] Flash memory (Boot ROM area) ................................... 16 Kbytes • Instruction execution time The fastest instruction at 26 MHz frequency ........................ 38 ns • Single power supply .................................................... 5 V ± 0.5 V • Interrupts ........... 6 external sources, 16 internal sources, 7 levels • Multi-functional 16-bit timer ................................................... 5 + 3 • Serial I/O (UART or Clock synchronous) ..................................... 2 • 10-bit A-D converter ............................................ 8-channel inputs • 8-bit D-A converter ............................................ 3-channel outputs • Real-time output .... 4 bits × 2 channels, or 6 bits × 1 channel + 2 bits × 1 channel • 12-bit watchdog timer • Programmable input/output (ports P0–P8, P10, P11) ............... 84 <Flash memory mode> • Power supply voltage .................................................. 5 V ± 0.5 V • Programming/Erase voltage ........................................ 5 V ± 0.5 V • Programming method ............
