M37733M4BXXXFP
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
DESCRIPTION
The M37733M4BXXXFP is a single-chip microcomputer using the 7700 Family core. This single-chip microcomputer has a CPU and a bus interface unit. The CPU is a 16-bit parallel processor that can be an 8-bit parallel processor, and the bus interface unit enhances the memory access efficiency to execute instructions fast. This microcomputer also includes a 32 kHz oscillation circuit, in addition to the ROM, RAM, multiple-function timers, serial I/O, A-D converter, and so on.
qSerial I/O (UART or clock synchronous) ..................................... 3 q10-bit A-D converter ............................................ 8-channel inputs q12-bit watchdog timer qProgrammable input/output (ports P0, P1, P2, P3, P4, P5, P6, P7, P8) ............................... 68 qClock generating circuit ........................................ 2 circuits built-in
APPLICATION
Control devices for general commercial equipment such as office automation, office equipment, and so on. Control devices for general industrial equipment such as communication equipment, and so on.
