DESCRIPTION

The M37733EHLXXXHP 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 PROM, 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.

The M37733EHLXXXHP has the same function as the M37733MHLXXXHP except that the built-in ROM is PROM. (Refer to the basic function blocks description.)
