The PD75116(A) is one of the 4-bit single-chip microcomputer 75X series. The PD75116(A) is a product with the extended ROM capacity of the PD75108(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 PD75116 have been improved by a wide variety of bit control instructions. The PD75116 is provided with interface inputs/outputs with peripheral circuits having different power voltages, and analog inputs and suitable for controlling automobile electrical equipment, etc. For the PD75116(A), an on-chip pin-compatible one-time PROM product (PD75P116) is separately available for system development evaluation. Functions are described in detail in the following User's Manual, which should be read when carrying out design work. |
