Description

The µPD75112(A) is one of the 4-bit single-chip micro-computer 75X series.

The µPD75112(A) is a product with the extended ROMcapacity of the µPD75108(A). In addition of high-speed operations, it can manipulate data in units of 1, 4 and 8 bits.  In particular, the I/O operation of the µPD75112(A) have been improved by a wide variety of bit control instructions.  The µPD75112(A) is provided with interface inputs/outputs with peripheral circuits having different power voltages, and analog inputs and suitable forcontrolling automobile electrical equipment, etc.  For the µPD75112(A)an on-chip pin-compatibleone-timePROM product (µPD75P116) is separately available forsystem development evaluation.
