4bit 1chip micro-controller for CD-DA
BU24591
The BU24591 is a 4bit 1chip micro-controller for CD-DA that integrates multiple I/O, such as 8bit 8-channel AD converter, pulse width counter, two lines of SIO, and LCD controller driver with 80 segment (Max.). All LCD segment can be switched into CMOS output by the program. These I/O achieves multi-function with few pins.
!Applications Portable CD-DA, CD radio cassette player
!Features 1) Low voltage, high-speed operation (VDD=2.3 to 3.6V at 4.
