DESCRIPTION
The 7540 Group is the 8-bit microcomputer based on the 740 family core technology.
The 7540 Group has a serial I/O, 8-bit timers, a 16-bit timer, and an A-D converter, and is useful for control of home electric appliances and office automation equipment.

FEATURES
• Basic machine-language instructions ....................................... 71
• The minimum instruction execution time .......................... 0.50 µs
   (at 8 MHz oscillation frequency for the shortest instruction)
• Memory size ROM ............................................ 16K to 32K bytes
                        RAM .............................................. 512 to 768 bytes
• Programmable I/O ports ........................................................... 29
                                                                        (25 in 32-pin version)
• Interrupts .................................................. 15 sources, 15 vectors
                                      (14 sources, 14 vectors for 32-pin version)
• Timers ............................................................................ 8-bit ✕ 4
                                                                                         16-bit ✕ 1
• Serial I/O1 ...................................................................... 8-bit ✕ 1
                                                        (UART or Clock-synchronized)
• Serial I/O2 ...................................................................... 8-bit ✕ 1
                                                                       (Clock-synchronized)
• A-D converter ................................................ 10-bit ✕ 8 channels
                                                        (6 channels for 32-pin version)
• Clock generating circuit ............................................. Built-in type
   (low-power dissipation by a ring oscillator enabled)
   (connect to external ceramic resonator or quartz-crystal oscillator
                                                                  permitting RC oscillation)
• Watchdog timer ............................................................ 16-bit ✕ 1
