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. When the device is not in operation and CS is high, it is put in standby mode and draws less than 30uA DC current.

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: X X A16 X A6 X A15 X A5 X A14 X A4 X A13 X A3 A20 A12 X A2 A19 A11 X A1 A18 A10 A8 A0 A17 A9 A7 P/N: PM0825 4 REV. 1.2, JUL. 01, 2004 MX23L1651 ELECTRICAL SPECIFICATIONS ABSOLUTE MAXIMUM RATINGS RATING Ambient Operating Temperature Storage Temperature Applied Input Voltage Applied Output Voltage VCC to Ground Potential VALUE 0 C to 70 C -55 C to 125 C -0.5V to 4.6V -0.5V to 4.6V -0.5V to 4.6V 3.During voltage transitions, all pins may overshoot to 4.6V or -0.5V for period up to 20ns. 4.All input and output pins may overshoot to VCC+0.5V while VCC+0.5V is smaller than or equal to 4.6V. 2.Specifications contained within the following tables are subject to change.
