V62C2161024L(L) Ultra Low Power 64K x 16 CMOS SRAM Features Functional Description • Ultra Low-power consumption - Active: 35mA ICC at 55ns - Stand-by: 5 µA (CMOS input/output) 1 µA (CMOS input/output, L version) The V62C2161024L is a Low Power CMOS Static RAM organized as 65,536 words by 16 bits. Easy memory expansion is provided by an active LOW (CE ) and (OE) pin. • 55/70/85/100 ns access time • Equal access and cycle time • Single +2.2V to 2.7V Power Supply This device has an automatic power-down mode feature when deselected. Separate Byte Enable controls (BLE and BHE) allow individual bytes to be accessed. BLE controls the lower bits I/O1 - I/O8. BHE controls the upper bits I/O9 - I/O16. Writing to these devices is performed by taking Chip Enable (CE) with Write Enable (WE) and Byte Enable (BLE/BHE) LOW. • Tri-state output • Automatic power-down when deselected Reading from the device is performed by taking Chip Enable (CE) with Output Enable (OE) and Byte Enable (BLE/BHE) LOW while Write Enable (WE) is held HIGH. • Multiple center power and ground pins for improved noise immunity • Individual byte controls for both Read and Write cycles • Available in 44 pin TSOP (II) Package Logic Block Diagram TSOP(II) Pre-Charge Circuit A4 A3 A2 A1 A0 CE I/O1 I/O2 I/O3 I/O4 Vcc Vss I/O5 I/O6 I/O7 I/O8 WE A15 A14 A13 A12 NC A0 A1 A3 A4 A5 A6 Row Select A2 A7 Vcc Vss Memory Array 1024 X 1024 A8 A9 I/O1 - I/O8 Data Cont I/O9 - I/O16 Data Cont I/O Circuit Column Select A10 A11 A12 A13 A14 A15 WE OE BHE BLE CE 1 REV. 1.1 April 2001 V62C2161024L(L) 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 A5 A6 A7 OE BHE BLE I/O16 I/O15 I/O14 I/O13 Vss Vcc I/O12 I/O11 I/O10 I/O9 NC A8 A9 A10 A11 NC V62C2161024L(L) Absolute Maximum Ratings * Parameter Symbol Minimum Maximum Unit Voltage on Any Pin Relative to Gnd Vt -0.5 +4.6 V Power Dissipation PT − 1.0 W Storage Temperature (Plastic) Tstg -55 +150 0 Temperature Under Bias Tbias -40 +85 0C C * Note: Stresses greater than those listed above Absolute Maximum Ratings may cause permanent damage to the device.

WE are high for read cycle. 2. All read cycle timing is referenced from the last valid address to the first transition address. 3. tHZ and tOHZ are defined as the time at which the outputs achieve the open circuit condition referenced to VOH or VOL levels. 4. At any given temperature and voltage condition tHZ (max.) is less than tLZ (min.) both for a given device and from device to device. 5. Transition is measured + 200mV from steady state voltage with load. This parameter is sampled and not 100% tested. 6. Device is continuously selected with CE = VIL. 7. Address valid prior to coincident with CE transition Low. 8. For common I/O applications, minimization or elimination of bus contention conditions is necessary during read and write cycle. 9.

All write timing is referenced from the last valid address to the first transition address. A write occurs during the overlap of a low CE and WE. A write begins at the latest transition among CE and WE going low: A write ends at the earliest transition among CE going high and WE going high. tWP is measured from the beginning of write to the end of write. 3. tCW is measured from the later of CE going low to end of write. 4. tAS is measured from the address valid to the beginning of write. 5. tWR is measured from the end of write to the address change. 6. If OE, CE and WE are in the Read Mode during this period, the I/O pins are in the output Low-Z state. Inputs of opposite phase of the output must not be applied because bus contention can occur. 7. For common I/O applications, minimization or elimination of bus contention conditions is necessary during read and write cycle. 8. If CE goes low simultaneously with WE going low or after WE going low, the outputs remain high impedance state. 9. DOUT is the read data of the new address. 10. When CE is low: I/O pins are in the outputs state. The input signals in the opposite phase leading to the output should not be applied. 11.

Transition is measured + 500mV from steady-state voltage. This parameter is guaranteed, but is not tested. WE is High for read cycle. CE and OE are LOW for read cycle. Address valid prior to or coincident with CE transition LOW. All read cycle timings are referenced from the last valid address to the first transtion address. CE or WE must be HIGH during address transition. All write cycle timings are referenced from the last valid address to the first transition address. 8 REV. 1.1 April 2001 V62C2161024L(L) V62C2161024L(L) Ordering Information Device Type* Speed Package V62C2161024L-55T V62C2161024L-70T V62C2161024L-85T V62C2161024L-100T 55 ns 70 ns 85 ns 100 ns 44-pin TSOP Type 2 V62C2161024LL-55T V62C2161024LL-70T V62C2161024LL-85T V62C2161024LL-100T 55 ns 70 ns 85 ns 100 ns * For Industrial temperature tested devices, an “I” designator will be added to the end of the device number. 9 REV. 1.1 April 2001 V62C2161024L(L) MOSEL VITELIC V62C2161024L(L) WORLDWIDE OFFICES U.S.A.
