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.
