X25138S

The X25138S is a CMOS 128K-bit serial E2PROM,internally organized as 16K x 8. The X25138 features a Serial Peripheral Interface (SPI) and software protocol allowing operation on a simple three-wire bus.The bus signals are a clock input (SCK) plus separate data in (SI) and data out (SO) lines. Access to the device is controlled through a chip select (CS) input,allowing any number of devices to share the same bus.

The features of X25138S can be summarized as :(1)5MHz Clock Rate; (2)Low Power CMOS: <1A Standby Current, <5mA Active Current; (3)2.5V To 5.5V Power Supply; (4)SPI Modes (0,0 & 1,1); (5)16K X 8 Bits, 2 Byte Page Mode; (6)Block Lock? Protection Protect 1/4, 1/2 or all of E2PROM Array; (7)Programmable Hardware Write Protection In-Circuit Programmable ROM Mode; (8)Built-in Inadvertent Write Protection Power-Up/Down protection circuitry: Write Enable Latch, Write Protect Pin; (9)Self-Timed Write Cycle 5ms Write Cycle Time (Typical); (10)High Reliability: Endurance: 100,000 cycles, Data Retention: 100 Years, ESD protection: 2000V on all pins; (11)Packages: 8-Lead XBGA, 8, 14-Lead SOIC, 8-Lead PDIP, 8-Lead TSSOP.

The absolute maximum ratings of the X25138S are: (1)Temperature under Bias: 65°C to +135°C; (2)Storage Temperature: 65°C to +150°C; (3)Voltage on any Pin with Respect to VSS: 1V to +7V; (4)D.C. Output Current: 5mA, (Soldering, 10 seconds): 300°C.
