UPD75112F

DATA SHEET MOS INTEGRATED CIRCUIT µPD75108F,75112F,75116F 4-BIT SINGLE-CHIP MICROCOMPUTER DESCRIPTION The µPD75116F offers high-speed operation (tCY = 1.91 µ s) at a low supply voltage (VDD = 2.7 V) which is not possible with the µPD75116. It has the same functions as, and is pin compatible with, the µPD75116, allowing low voltage sets to be developed by making efficient use of previously developed and used software resources. Note, however, that the operating voltage range is different from that of the µPD75116. A version of the µPD75116F with on-chip PROM, the µPD75P116* , is also available for evaluation during system development. * There are some differences in electrical specifications between the µPD75116F and the µPD75P116. Functions are described in detail in the following User’s Manual, which should be read when carrying out design work. µPD75116 User’s Manual : IEM-922 FEATURES µPD75116 low voltage high-speed operation product Instruction execution time Ta = –40 to +50 °C VDD = 2.7 to 5.0 V 1.91 µs , 15.3 µs (operation at 4.19 MHz) 2 µs, 4 µs, 32 µs (operation at 2 MHz) 1.91 µs , 15.3 µs (operation at 4.19 MHz) 2 µs, 4 µs, 32 µs (operation at 2 MHz) 0.95 µs, 1.91 µs, 15.3 µs (operation at 4.19 MHz) Ta = –40 to +60 °C VDD = 2.8 to 5.0 V VDD = 4.5 to 5.0 V 43 systematically arranged instructions 8-bit data transfer, compare, operation and increment/decrement instructions GETI instruction allowing any 2-byte or 3-byte instruction to be implemented in 1...
