M34570M4-XXXFP Datasheet
Edited by (http://www.seekic.com/),the leading IC purchasers' best choice of platform for one-stop valued service!
Description:
The 4570 Group is a 4-bit single-chip microcomputer designed with CMOS technology. Its CPU is that of the 4500 series using a simple, high-speed instruction set. The computer is equipped with a carrier wave output circuit for remote control, an 8-bit timer with a reload register, a 10-bit timer with a reload register, and an 8-bit timer with two reload registers.
The various microcomputers in the 4570 Group include variations of the built-in memory size. The mask ROM version and One Time PROM version of 4570 Group are produced as shown in the table below.
