DESCRIPTION

The M37733EHBXXXFP 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.

The M37733EHBXXXFP has the same function as the M37733MHBXXXFP except that the built-in ROM is PROM. (Refer to the basic function blocks description.) For program development, the M37733EHBFS with erasable ROM that is housed in a windowed ceramic LCC is also provided.
