UL62H256ASA35G1 Overview

Low Voltage Automotive Fast 32K x 8 SRAM

UL62H256A
Low Voltage 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 UL62H256A 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 < 40 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 2.5 - 3.6 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
