ow Voltage Read
The IS93C66-3 has been designed to ensure that data
read operations are reliable in low voltage environments.
The IS93C66-3 is guaranteed to provide accurate data
during read operations with Vcc as low as 2.7V.
Auto Increment Read Operations
In the interest of memory transfer operation applications,
the IS93C66-3 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 16 bits of the addressed word have
been clocked out, the data in consecutively higher address
locations (the address
“
000000
”
is assumed as the ad-
dress of
“
111111"
) 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.
Write Enable (WEN
)
The write enable (WEN) instruction must be executed
before any device programming (WRITE, WRALL, ERASE,
and ERAL) can be done. When Vcc is applied, this device
powers up in the write disabled state. The device then
ENDURANCE AND DATA RETENTION
The IS93C66-3 is designed for applications requiring up
to 100,000 programming cycles (WRITE, WRALL, ERASE
and ERAL). It provides 10 years of secure data retention,
without power after the execution of 100,000 programming
cycles.
DEVICE OPERATION
The IS93C66-3 is controlled by seven 11-bit instructions.
Instructions are clocked in (serially) on the D
IN
pin. Each
instruction begins with a logical
“
1
”
(the start bit). This is
followed by the opcode (2 bits), the address field (8 bits),
and data, if appropriate. The clock signal (SK) may be
halted at any time and the IS93C66-3 will remain in its last
state. This allows full static flexibility and maximum
power conservation.
Read (READ)
The READ instruction is the only instruction that outputs
serial data on the D
OUT
pin. After the read instruction and
address have been decoded, data is transferred from the
selected memory register into a 16-bit serial shift register.
(Please note that one logical
“
0
”
bit precedes the actual
16-bit output data string.) The output on D
OUT
changes
during the low-to-high transitions of SK (see Figure 3).
