SUMMARY DESCRIPTION  
This specification covers a range of 4K, 2K, 1K bit  
serial Electrically Erasable Programmable Memo-  
ry (EEPROM) products (respectively for M93S66,  
M93S56, M93S46). In this text, these products are  
collectively referred to as M93Sx6.  
and instructions used to set the memory protec-  
tion. These are summarized in Table 2. and Table  
3.).  
A Read Data from Memory (READ) instruction  
loads the address of the first word to be read into  
an internal address pointer. The data contained at  
this address is then clocked out serially. The ad-  
dress pointer is automatically incremented after  
the data is output and, if the Chip Select Input (S)  
is held High, the M93Sx6 can output a sequential  
stream of data words. In this way, the memory can  
be read as a data stream from 16 to 4096 bits (for  
the M93S66), or continuously as the address  
counter automatically rolls over to 00h when the  
highest address is reached.

Within the time required by a programming cycle  
(t ), up to 4 words may be written with help of the

Page Write instruction. the whole memory may  
also be erased, or set to a predetermined pattern,  
by using the Write All instruction.

Within the memory, a user defined area may be  
protected against further Write instructions. The  
size of this area is defined by the content of a Pro-  
tection Register, located outside of the memory ar-  
ray. As a final protection step, data may be  
permanently protected by programming a One  
Time Programming bit (OTP bit) which locks the  
Protection Register content.

Programming is internally self-timed (the external  
clock signal on Serial Clock (C) may be stopped or  
left running after the start of a Write cycle) and  
does not require an erase cycle prior to the Write  
instruction. The Write instruction writes 16 bits at a  
time into one of the word locations of the M93Sx6,  
the Page Write instruction writes up to 4 words of  
16 bits to sequential locations, assuming in both  
cases that all addresses are outside the Write Pro-  
tected area. After the start of the programming cy-  
cle, a Busy/Ready signal is available on Serial  
Data Output (Q) when Chip Select Input (S) is driv-  
en High.

The M93Sx6 is accessed through a serial input (D)  
and output (Q) using the MICROWIRE bus proto-  
col. The memory is divided into 256, 128, 64 x16  
bit words (respectively for M93S66, M93S56,  
M93S46).
