Milpitas, Calif.--June 23, 1997--Xicor Inc. (Milpitas, Calif.) announced their fastest 32-kbit EEPROM with a Serial Peripheral Interface (SPI).
The X25330 transfers data at 5 Mbps which is 67 percent faster than existing 32-kbit SPI devices. In addition, the new chip has two memory protection modes that reduce the chip count in customer designs by eliminating the need for an extra EPROM or ROM for sensitive read-only data.
The X25330 can be used to increase the speed of existing products since it is a pin-for-pin replacement for existing 32-kbit SPI EEPROM memories.
The device can also boost performance of new products in a wide range of applications including telecommunications, consumer products, computer peripherals, industrial products, and automotive systems.
The X25330 has a Block Lock or In-Circuit Programmable ROM mode that eliminates the need for an additional EPROM or ROM to hold sensitive read-only data.
The Block Lock mode allows certain memory segments to be "write locked" to protect the data from inadvertent writes that could corrupt sensitive information such as billing information or serial numbers.
The In Circuit Programmable ROM mode allows engineers to permanently lock certain portions of data as read-only in the manufacturing process. This is important in cases where critical system information such as calibration data needs to be protected.
The X25330 has standby current of 1 A (maximum) and operates at voltages from 5 V down to 2.5 V, which makes the device ideal for battery powered products. The smaller than "thumb tack" sized packages (SOIC and TSSOP) of the new device are also important for the small size of battery-based products.
The X25330 is sampling now with production quantities available in the third quarter of 1997. The device is priced at $1.46 for 10,000-piece quantities in either an 8-pin SOICor in a 14-pin TSSOP.
