TC55NEM208AFPV/AFTV55,70  
TENTATIVE TOSHIBA MOS DIGITAL INTEGRATED CIRCUIT SILICON GATE CMOS  
524,288-WORD BY 8-BIT STATIC RAM  
DESCRIPTION  
The TC55NEM208AFPV/AFTV is a 4,194,304-bit static random access memory (SRAM) organized as 524,288  
words by 8 bits. Fabricated using Toshiba's CMOS Silicon gate process technology, this device operates from a  
single 2.7 to 5.5 V power supply. Advanced circuit technology provides both high speed and low power at an  
operating current of 3 mA/MHz (typ) and a minimum cycle time of 55 ns. It is automatically placed in low-power  
mode at 1 µA standby current (typ) when chip enable (CE ) is asserted high. There are two control inputs. CE is  
used to select the device and for data retention control, and output enable (OE ) provides fast memory access. This  
device is well suited to various microprocessor system applications where high speed, low power and battery  
backup are required. And, with a guaranteed operating range of −40° to 85°C, the TC55NEM208AFPV/AFTV can  
be used in environments exhibiting extreme temperature conditions. The TC55NEM208AFPV/AFTV is available in  
a standard plastic 32-pin small-outline package (SOP) and normal and reverse pinout plastic 32-pin  
thin-small-outline package (TSOP).
