Series Structure
Usage Notes
The LC58E76 is designed for use in developing and evaluating programs for the microprocessors in the
LC587X series. However, there are differences between the LC58E76 and the mask ROM versions. Keep the
following points in mind when using the LC58E76.
1. Notes on Reset
2. Cover the LC58E76’s window with an opaque seal when writing data to EPROM.
3. The LC58E76 and the mask ROM versions differ in the following points.
Note: Although the strobes number 00 to 1E can be used with CF 2 MHz and lower specifications, strobes number 0E, 0F and 1E cannot be used with the

When the RES pin input changes from high to low, the reset state is cleared after the prescribed oscillator
stabilization period has elapsed. The options and the segment PLA are set up during the first 256 cycles following the
clearing of the reset state. Instructions are executed starting at location 0 after this setup phase has completed. (The
options are undefined and the segment outputs are held at the V
256 cycles following the clearing of the reset state.)
