U62H256A

Automotive Fast 32K x 8 SRAM

Features

32768 x 8 bit static CMOS RAM

35 and 55 ns Access Time

Common data inputs and

Description

go High-Z until the new information

is available. The data outputs have

no preferred state. The Read cycle

is finished by the falling edge of W,

or by the rising edge of E, respec-

tively.

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.

The U62H256A is a static RAM

manufactured using a CMOS pro-

cess technology with the following

operating modes:

data outputs

- Read

- Standby

Three-state outputs

- Write

- Data Retention

Typ. operating supply current

The memory array is based on a

35 ns: 45 mA

6-transistor cell.

55 ns: 30 mA

Standby current < 50 µA at 125 °C The circuit is activated by the fal-

ling edge of E. The address and

TTL/CMOS-compatible

control inputs open simultaneously.

Power supply voltage 5 V

According to the information of W

Operating temperature range

-40 °C to 85 °C

and G, the data inputs, or outputs,

-40 °C to 125 °C

are active. In a Read cycle, the

data outputs are activated by the

falling edge of G, afterwards the

ESD protection > 2000 V

(MIL STD 883C M3015.7)

data word will be available at the

outputs DQ0-DQ7. After the
