GENERAL DESCRIPTION
The MX23L1651 is a CMOS 16,777,216 bit serial Mask
ROM, which is configured as 2,097,152 x 8 internally. The
MX23L1651 features a serial peripheral interface and
software protocol allowing operation on a simple 3- wire
bus. The three bus signals are a clock input (SCLK), a
serial data input (SI), and a serial data output (SO). Serial
peripheral interface access to the device is enabled by CS
input.
The MX23L1651 provide sequential read operation on the
whole chip.
PIN CONFIGURATIONS
PIN DESCRIPTION
When the device is not in operation and CS is high, it is put
in standby mode and draws less than 30uA DC current.

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 interface. The read operation is executed on a segment
(512 bytes) basis. If the end of the segment is reached then the device will wrap around to the beginning of the segment.
(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
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:
AD1:First Address Bit sequence:
AD2:Second Address Bit sequence:
AD3:Thrid Address Bit sequence:

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. While CS=VIH, current=standby current, while
CS=VIL and commands are issuing, or commands are invalid, current=5mA(typ.) to 15mA(max.).
