1 / 12 page TC55NEM216ASTV55,70 2002-10-30 1/12 TENTATIVE TOSHIBA MOS DIGITAL INTEGRATED CIRCUIT SILICON GATE CMOS 262,144-WORD BY 16-BIT FULL CMOS STATIC RAM DESCRIPTION The TC55NEM216ASTV is a 4,194,304-bit static random access memory (SRAM) organized as 262,144 words by 16 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 or chip select (CS) is asserted low. There are three control inputs. CE is used to select the device and for data retention control, and output enable ( OE ) provides fast memory access. Data byte control pin ( LB , UB ) provides lower and upper byte 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 extreme temperature range of −40° to 85°C, the TC55NEM216ASTV can be used in environments exhibiting extreme temperature conditions. The TC55NEM216ASTV is available in a plastic 44-pin thin-small-outline package (TSOP). FEATURES • Low-power dissipation Operating: 15 mW/MHz (typical) • Single power supply voltage of 2.7 to 5.5 V • Power down features using CE • Data retention supply voltage of 2.0 to 5.5 V • Direct TTL compatibility for all inputs and outputs • Wide operating temperature range of −40° to 85°C • Standby Current (maximum): 20 µA PIN ASSIGNMENT (TOP VIEW) 44 PIN TSOP PIN NAMES A0~A17 Address Inputs CE Chip Enable CS Chip Select R/W Read/Write Control OE Output Enable LB , UB Data Byte Control I/O1~I/O16 Data Inputs/Outputs VDD Power GND Ground NC No Connection • Access Times (maximum): TC55NEM216ASTV 55 70 Access Time 55 ns 70 ns CE Access Time 55 ns 70 ns OE Access Time 30 ns 35 ns • Package: TSOP II44-P-400-0.80 (Weight: g typ) A4 A3 A2 A1 A0 I/O1 I/O2 I/O3 I/O4 VDD GND I/O5 I/O6 I/O7 I/O8 R/W A15 A14 A13 A12 A16 A5 A6 A7 I/O16 I/O15 I/O14 I/O13 GND VDD I/O12 I/O11 I/O10 I/O9 CS A8 A9 A10 A11 A17 1 44 2 43 3 42 4 41 5 40 6 39 7 38 8 37 9 36 10 35 11 34 12 33 13 32 14 31 15 30 16 29 17 28 18 27 19 26 20 25 21 24 22 23 OE UB LB CE |
