UL62H256B  
Low Voltage Automotive Fast 32K x 8 SRAM  
Features  
Description  
The UL62H256B is a static RAM  
manufactured using a CMOS pro-  
cess technology with the following  
operating modes:  
F 32768 x 8 bit static CMOS RAM  
F 35 and 55 ns Access Time  
F Common data inputs and  
data outputs  
address change, the data outputs  
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 1.5 V. With the exception of E, all  
inputs consist of NOR gates, so  
that no pull-up/pull-down resistors  
are required.  
F Three-state outputs  
F Typ. operating supply current  
35 ns: 45 mA  
- Read  
- Write  
- Standby  
- Data Retention  
The memory array is based on a  
6-Transistor cell.  
55 ns: 30 mA  
F Standby current < 30 µA at 125 °C The circuit is activated by the fal-  
F Power supply voltage 2.5 V  
F 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  
-40 °C to 125 °C  
F CECC 90000 Quality Standard  
F ESD protection > 2000 V  
(MIL STD 883C M3015.7)  
F Latch-up immunity >100 mA  
F Package: SOP28 (300/330 mil)
