The UL62H1616A is a static RAM

manufactured using a CMOS pro-

cess technology with the following

operating modes:

- Lower / Upper Byte Read

- Word Read

- Lower / Upper Byte Write

- Word Write

- Standby

- Data Retention

The memory array is based on a

6-Transistor cell.

The circuit is activated by the fal-

ling edge of E. The address and

control inputs open simul taneously.

According to the information of W

and G, the data inputs, or outputs,

are active. During the active state

E = L and W = H each address

change lead s to a new Read cycle.

In a Read cycle, the data outputs

are activated by the falling edge of

G. If LB = L the data lower byte will

be available at the outputs DQ0-

DQ7, on UB = L the data upper

byte appear at the outputs DQ8-

DQ15. After the address change,

the data outputs go High-Z until the

new information is available. The

data outputs have no preferred

st ate. The Read cycle is finished by

the falling edge of W, or by the

rising edge of E, respecti ve ly.

Data retention is guaranteed down

to 2 V. With the exception of E, all

inputs consist of NOR gates, so

that no pull-up/pull-down resistors

are required.

Characteristics

**Not more than 1 output should be shorted at the same time. Duration of the short circuit should not exceed 30 s.

All voltages are referenced to VSS = 0 V (ground).

All charac teristics are valid in the power supply voltage range and in th e operati ng te mperatu re range s pecified.

Dynamic measurements are based on a rise and fall tim e of ≤ 5 ns, measured between 10 % and 90 % of VI, as well as

input levels of VIL = 0 V and VIH = 2.5 V. The timing reference level of all input and output signals is 1.5 V,

with the exception of the tdis-times and ten-times, in which ca ses t ransition is measured ±200 mV from s tead y-s tate vol tag e.
