U62H1708

Automotive Fast 128K x 8 SRAM

Features

Description

The U62H1708 is a static RAM

manufactured using a CMOS pro-

cess technology with the following

operating modes:

! 131072 x 8 bit static CMOS RAM

! 35 and 55 ns Access Time

! Common data inputs and

data outputs

available at the outputs DQ0-DQ7.

After the address change, the data

outputs go High-Z until the new

information is available. The data

outputs have no preferred state. If

the memory is driven by CMOS

levels in the active state, and if

there is no change of the address,

data input and control signals W or

G, the operating current (I_O= 0 mA)

drops to the value of the operating

current in the Standby mode. The

Read cycle is finished by the falling

edge of E2 or W, or by the rising

edge of E1, respectively.

- Read

- Write

- Standby

! Three-state outputs

! Typ. operating supply current

35 ns: 45mA

- Data Retention

The memory array is based on a

6-Transistor cell.

55 ns: 30mA

The circuit is activated by the rising

edge of E2 (at E1 = L), or the falling

edge of E1 (at E2 = H). The

address and control inputs open

simultaneously. According to the

information of W and G, the data

inputs, or outputs, are active.

During the active state (E1 = L and

E2 = H) each address change

leads to a new Read cycle. In a

Read cycle, the data outputs are

activated by the falling edge of G,

afterwards the data word will be

! Standby current <200µA at 125°C

! TTL/CMOS-compatible

! Power supply voltage 5 V

! Operating temperature range

-40 °C to 85 °C

-40 °C to 125 °C

! QS 9000 Quality Standard

! ESD protection > 2000 V

(MIL STD 883C M3015.7)

! Latch-up immunity >100 mA

! Package: SOP32 (450 mil)

TSOP I 32

Data retention is guaranteed down

to 2 V. With the exception of E1

and E2, all inputs consist of NOR

gates, so that no pull-up/pull-down

resistors are required.
