UL62H256A

Low Voltage Automotive Fast 32K x 8 SRAM

Features

Description

! 32768 x 8 bit static CMOS RAM

! 35 and 55 ns Access Time

! Common data inputs and

data outputs

The UL62H256A is a static RAM

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.

manufactured using a CMOS pro-

cess technology with the following

operating modes:

! Three-state outputs

! Typ. operating supply current

35 ns: 45 mA

- Read

- Write

- Standby

- Data Retention

The memory array is based on a

6-Transistor cell.

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.

55 ns: 30 mA

! Standby current < 40 µA at 125 °C The circuit is activated by the fal-

! TTL/CMOS-compatible

! Power supply voltage 2.5 - 3.6 V

! Operating temperature range

-40 °C to 85 °C

ling edge of E. The address and

control inputs open simultaneously.

According to the information of W

and G, the data inputs, or outputs,

are active. In a Read cycle, the

data outputs are activated by the

falling edge of G, afterwards the

data word will be available at the

outputs DQ0-DQ7. After the

address change, the data outputs

-40 °C to 125 °C

! QS 9000 Quality Standard

! ESD protection > 2000 V

(MIL STD 883C M3015.7)

! Latch-up immunity >100 mA

! Package: SOP28 (300/330 mil)
