... PROM) version of Sanyo's LC6529N/F/L 4-bit single-chip CMOS microcontroller. It provides identical functionality to, and pin compatibility with, the mask ROM versions of the LC6529N/F/L, and provides a 1-KB internal PROM. The LC65P29 is provided in DIP24S and MFP30S plastic packages and the program can be written by the customer, thus makes this IC appropriate for the limited-run products and the startup of initial production of new products ...
