INSTRUCTIONS
The instruction set of the M93Cx6 devices con-
tains seven instructions, as summarized in Table
lowing parts, as shown in Figure 4.:
s
Each instruction is preceded by a rising edge
on Chip Select Input (S) with Serial Clock (C)
being held Low.
s
A start bit, which is the first ‘1’ read on Serial
Data Input (D) during the rising edge of Serial
Clock (C).
s
Two op-code bits, read on Serial Data Input
(D) during the rising edge of Serial Clock (C).
(Some instructions also use the first two bits of
the address to define the op-code).
s
The address bits of the byte or word that is to
be accessed. For the M93C46, the address is
made up of 6 bits for the x16 organization or 7
bits for the x8 organization (see Table 5.). For
the M93C56 and M93C66, the address is
made up of 8 bits for the x16 organization or 9
bits for the x8 organization (see Table 6.). For
the M93C76 and M93C86, the address is
made up of 10 bits for the x16 organization or
11 bits for the x8 organization (see Table 7.).
The M93Cx6 devices are fabricated in CMOS
technology and are therefore able to run as slow
as 0 Hz (static input signals) or as fast as the max-
