com TC55NEM208AFPN/AFTN55,70 TENTATIVE TOSHIBA MOS DIGITAL INTEGRATED CIRCUIT SILICON GATE CMOS 524,288-WORD BY 8-BIT STATIC RAM DESCRIPTION The TC55NEM208AFPN/AFTN 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 5V ± 10% 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 TC55NEM208AFPN/AFTN can be used in environments exhibiting extreme temperature conditions.
The TC55NEM208AFPN/AFTN 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).
FEATURES • • • • • • • Low-power dissipation Operating: 15 mW/MHz (typical) Single power supply voltage of 5 V ± 10% Power down features using CE .
