GENERAL DESCRIPTION
DataShee
The MX23L8051 is a CMOS 8,338,608 bit seriDalaMtaaSshkeet4UT.choemMX23L8051 provide sequential read operation on the
ROM, which is configured as 1,048,576 x 8 internally. The whole chip.
MX23L8051 features a serial peripheral interface and
software protocol allowing operation on a simple 3- wire When the device is not in operation and CS is high, it is put
bus. The three bus signals are a clock input (SCLK), a in standby mode and draws less than 30uA DC current.
serial data input (SI), and a serial data output (SO). Serial
peripheral interface access to the device is enabled by CS
input.

DEVICE OPERATION
1.When incorrect command is inputted to this LSI, this LSI becomes standby mode and keeps the standby mode until
next CS falling edge. In standby mode, SO pin of this LSI should be High-Z.
2.When correct command is inputted to this LSI, this LSI becomes active mode and keeps the active mode until next CSB
rising edge.
COMMAND DESCRIPTION
(1) Read Array
This command is sent with the 4-byte address (command included), and the byte address, followed by four dummy bytes
sent to give the device time to stabilize. The device will then send out data starting at the byte address until CS goes
high. The clock to clock out the data is supplied by the master serial peripheral interface.
(2) Standby Mode
When CS is high and there is no operation in progress, the device is put in standby mode. Typical standby current is less
than 30uA.

DATA SEQUENCE
DataShee
DataSheet4U.com
Output data is serially sent out through SO pin, synchronized with the rising edge of SCLK, whereas input data is serially
read in through SI pin, synchronized with the rising edge of SCLK. The bit sequence for both input and output data is bit
7 (MSB) first, then bit 6, bit 5, ...., and bit 0.(LSB)
ADDRESS SEQUENCE
The address assignment is described as follows :
BA: Byte address Bit sequence:
X A6 A5 A4 A3 A2 A1 A0
AD1:First Address Bit sequence:
X X X X X A19 A18 A17
AD2:Second Address Bit sequence: A16 A15 A14 A13 A12 A11 A10 A9
AD3:Thrid Address Bit sequence: X X X X X X A8 A7
