M37735S4LHP
16-BIT CMOS MICROCOMPUTER
DESCRIPTION
The M37735S4LHP is a microcomputer using the 7700 Family core. This 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 RAM, multiple-function timers, serial I/O, A-D converter, and so on. Its strong points are the low power dissipation, the low supply voltage, and the small package.
qInterrupts ............................................................ 19 types, 7 levels qMultiple-function 16-bit timer ................................................. 5 + 3 qSerial I/O (UART or clock synchronous)..........................................3 q10-bit A-D converter ..............................................8-channel inputs q12-bit watchdog timer qProgrammable input/output (ports P4, P5, P6, P7, P8) ..............................................................37 qClock generating circuit ........................................ 2 circuits built-in qSmall package.......................80-pin plastic molded fine-pitch QFP (80P6D-A; 0.5 mm lead pitch)
FEATURES
qNumber of basic instructions .................................................. 103 qMemory size RAM ................................................ 2048 bytes qInstruction execution time The fastest instruction at 12 MHz frequency .......................333 ns qSingle power supply ..................................................... 2.7 – 5.5 V qLow power dissipation (At 3 V supply voltage, 12 MHz frequency) ............................................ 10.8 mW (Typ.)
