5 Instructions
Instructions
The instruction set of the M93Cx6 devices contains seven instructions, as summarized in
Table 4 to Table 6. Each instruction consists of the following parts, as shown in Figure 5:
READ, WRITE, WEN, WDS sequences:
Each instruction is preceded by a rising edge on Chip Select Input (S) with Serial Clock
(C) being held low.
A start bit, which is the first ‘1’ read on Serial Data Input (D) during the rising edge of
Serial Clock (C).
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).
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 4). 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 5). 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 6).
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 maximum ratings specified in “AC
characteristics” tables, in Section 10: DC and AC parameters.
