FEATURES

INTRODUCTION

The UT8Q512E RadTol product is a high-performance CMOS

static RAM organized as 524,288 words by 8 bits. Easy memory

expansion is provided by an active LOW Chip Enable (E), an

active LOW Output Enable (G), and three-state drivers.

20ns maximum (3.3 volt supply) address access time

Asynchronous operation for compatibility with industry-

standard 512K x 8 SRAMs

TTL compatible inputs and output levels, three-state

bidirectional data bus

Writing to the device is accomplished by taking Chip Enable (E)

and Write Enable (W) inputs LOW. Data on the eight I/O pins

Operational environment:

- Total dose: 50 krads(Si)

(DQ through DQ ) is then written into the location specified

on the address pins (A through A ). Reading from the device

- SEL Immune 110 MeV-cm /mg

is accomplished by taking Chip Enable (E) and Output Enable

(G) LOW while forcing Write Enable (W) HIGH. Under these

conditions, the contents of the memory location specified by the

address pins will appear on the I/O pins.

- SEU LET (0.25) = 52 cm MeV

- Saturated Cross Section 2.8E-8 cm /bit

-<1.1E-9 errors/bit-day, Adams 90% worst case

environment geosynchronous orbit

The eight input/output pins (DQ through DQ ) are placed in a

high impedance state when the device is deselected (E HIGH),

the outputs are disabled (G HIGH), or during a write operation

(E LOW and W LOW).

Packaging:

- 36-lead ceramic flatpack (3.831 grams)

Standard Microcircuit Drawing 5962-99607

- QML Q and V compliant part
