GENERAL DESCRIPTION
MX23L1651 CMOS 16,777,216 serial Mask ROM, which configured 2,097,152 internally. MX23L1651 features serial peripheral interface software protocol allowing operation simple wire bus. three signals clock input (SCLK), serial data input (SI), serial data output (SO). Serial peripheral interface access device enabled input. MX23L1651 provide sequential read operation whole chip. When device operation high, standby mode draws less than 30uA current.

DEVICE OPERATION
1.When incorrect command inputted this LSI, this becomes standby mode keeps standby mode until next falling edge. standby mode, this should High-Z. 2.When correct command inputted this LSI, this becomes active mode keeps active mode until next rising edge.
COMMAND DESCRIPTION Read Array
This command sent with 4-byte address (command included), byte address, followed four dummy bytes sent give device time stabilize. device will then send data starting byte address until goes high. clock clock data supplied master serial interface. read operation executed segment (512 bytes) basis. segment reached then device will wrap around beginning segment. Standby Mode When high there operation progress, device standby mode. Typical standby current less than 30uA.
DATA SEQUENCE
Output data serially sent through pin, synchronized with rising edge SCLK, whereas input data serially read through pin, synchronized with rising edge SCLK. sequence both input output data (MSB) first, then 0.(LSB)
ADDRESS SEQUENCE
address assignment described follows Byte address sequence: AD1:First Address sequence: AD2:Second Address sequence: AD3:Thrid Address sequence:
