Santa Clara, Calif. QP Semiconductor's newest family of CMOS UV PROMS that feature low-power consumption and high speeds to 15 ns. The devices are complete redesigns of Cypress high-speed PROMs.
Devices are available initially in hermetic packages for military, aerospace and industrial applications. Plastic versions could also be available based on customer demand.
"When we reviewed the world demand for UV PROMs we realized that there would soon be a shortage of certain part numbers," said Jim Townsend, director, marketing. "So we embarked on a program to redesign pin-for-pin equivalent devices. We picked the parts that we felt had the widest appeal and also had demonstrated demand. Our business practice is to provide solutions to our customers for obsolete and hard-to-get parts and this redesign effort should serve our customers well."
The family offers the advantage of high-speed, low-power and proven high programming yield. They are all eight-bit wide memories available either as a one-time- programmable (OTP) device or in a windowed package to allow for reprogrammability. The memory cells utilize proven CMOS PROM floating-gate technology. The I/Os are TTL compatible. Devices are available in memory sizes from 4 Kbytes to 512 Kbytes in a wide range of memory configurations and speed ranges. The QP7C225A for example is a 4K device, configured 512 X 8 (registered). The devices are available in 25, 30, and 35ns speeds.
Most products are sampling now and are available in either industrial grade hermetic packages or full mil qualified QML hermetic packages. Pricing in quantities of 100 pieces begin at $12.50 each depending on package type and screening requirements. Windowed and windowless package types include standard DIPs (300 and 600 mil) flatpack, and leadless chip carriers.
All products have been qualified and may be ordered using their SMD number, listed with DSCC, or their standard ordering code. QP PDF data sheets can be accessed at: www.qpsemi.com/literature.
