The GMS97C5x, 97L5x are programmed by using a modified Quick-Pulse Programming
TM
algorithm. It
differs from older methods in the value used for Vpp (programming supply voltage) and in the width and
number of the ALE/PROG pulses. The GMS97C5x, 97L5x contains two signature bytes that can be read
and used by an EPROM programming system to identify the device. The signature bytes identify the device
as an manufactured by LGS. Table 11 shows the logic levels for reading the signature byte, and for
programming the program memory, the encryption table, and the security bits. The circuit configuration
and waveforms for quick-pulse programming are shown in Figures 12 and 13. Figure 14 shows the circuit
configuration for normal program memory verification.
