V62C3802048L(L) Ultra Low Power 256K x 8 CMOS SRAM Features Functional Description • Low-power consumption - Active: 40mA at 35ns - Stand-by: 10 µA (CMOS input/output) 2 µA CMOS input/output, L version The V62C3802048L is a low power CMOS Static RAM organized as 262,144 words by 8 bits. Easy memory expansion is provided by an active LOW CE1, an active HIGH CE2, an active LOW OE , and Tri-state I/O’s. This device has an automatic power-down mode feature when deselected. • Single + 2.7 to 3.3V Power Supply Writing to the device is accomplished by taking Chip Enable 1 (CE1) with Write Enable (WE ) LOW, and Chip Enable 2 (CE2) HIGH. Reading from the device is performed by taking Chip Enable 1 (CE1) with Output Enable (OE) LOW while Write Enable (WE ) and Chip Enable 2 (CE2) is HIGH. The I/O pins are placed in a high-impedance state when the device is deselected: the outputs are disabled during a write cycle. • Equal access and cycle time • 35/45/55/70/85/100 ns access time • Easy memory expansion with CE1, CE2 and OE inputs • 1.0V data retention mode • TTL compatible, Tri-state input/output • Automatic power-down when deselected • Package available: 32-TSOP1 / STSOP • 48 Ball CSP_BGA Logic Block Diagram The V62C3802048LL comes with a 1V data retention feature and Lower Standby Power. The V62C3802048L is available in a 32-pin 8 x 20 mm TSOP1/8 x 13.4mm STSOP and CSP type 48-fpBGA packages. 32-Pin TSOP1 / STSOP(CSP_BGA see next page) A11 A9 A8 A13 WE CE2 A15 ROW DECODER A3 A4 A5 A6 A7 A8 A9 SENSE AMP INPUT BUFFER A0 A1 A2 Cell Array A 11 A14 A12 A7 A6 A5 A4 I/O1 COLUMN DECODER A10 Vcc A17 A16 I/O8 A12 A 13 A 14 A 15 CONTROL CIRCUIT A 16 A 17 OE WE CE1 CE2 1 REV. 1.2 May 2001 V62C3802048L(L) 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 32 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 OE A10 CE1 I/O8 I/O7 I/O6 I/O5 I/O4 GND I/O3 I/O2 I/O1 A0 A1 A2 A3 V62C3802048L(L) MOSEL VITELIC V62C3802048L(L)B 1 2 3 4 5 6 1 2 3 4 5 6 A A0 A1 CS2 A3 A6 A8 B I/O5 A2 WE A4 A7 I/O1 C I/O6 NC NC A5 NC I/O2 D VSS NC NC NC NC VCC E VCC NC NC NC NC VSS F I/O7 NC NC A17 NC I/O3 G I/O8 OE CS1 A16 A15 I/O4 H A9 A10 A11 A12 A13 A14 Note: NC means no Ball.

Transition is measured + 500mV from steady-state voltage. This parameter is guaranteed, but is not tested. WE is HIGH for read cycle. CE1 and OE are LOW and CE2 is HIGH for read cycle. Address valid prior to or coincident with CE1 transition LOW or CE2 transition HIGH. All read cycle timings are referenced from the last valid address to the first transtion address.
