Functional Description
Endurance and data retention
The AM93LC86 is designed for applications
requiring up to 1M programming cycles (WRITE,
WRAL, EARSE and ERAL). It provides 40 years of
secure data retention.
Device operation
The AM93LC86 is controlled by seven 13-bit
instructions. Instructions are clocked in (serially) on
the DI pin. Each instruction begins with a logical "1"
(the start bit). This is followed by the opcode (2 bits),
the address field (10/11 bits), and data, if
appropriated,. The clock signal (SK) may be halted
at any time and the AM93LC86 will remain in its last
state. This allows full static flexibility and maximum
power conservation.
Auto increment read operations
Sequential read is possible, since the AM93LC86
has been designed to output a continuous stream
of memory
content
in
response to a
single
read
operation instruction. To utilize this function, the
system asserts a read instruction specifying a start
location address. Once the 8-bit or 16-bit of the
addressed word have been clocked out, the data in
consecutively higher address locations is output.
The address will wrap around continuously with CS
high until the chip select (CS) control pin is brought
low. This allows for single instruction data dumps to
be executed with a minimum of firmware overhead.
Read (READ)
The READ instruction is the only instruction that
outputs serial data on the DO pin. After the read
instruction and address have been decoded, data is
transferred from the selected memory register into
a 8-bit or 16-bit serial shift register. (Please note
that one logical "0" bit precedes the actual 8-bit or
16-bit output data string.) The output on DO
changes during the rising edge transitions of SK.
