A62S6308-SI series: *Operating: 40mA (max.) *Standby: 30ľA (max.) n Extended operating temperature range:-25° to 85° C C n Full static operation, no clock or refreshing required n All inputs and outputs are directly TTL-compatible n Common I/O using three-state output n Output enable and two chip enable inputs for easy application n Data retention voltage: 2V (min.) n Available in 32-pin SOP, TSOP, sTSOP (8 X 13.4mm) forward type and 36-ball Mini BGA (6X8) packages
General Description
The A62S6308 is a low operating current 524,288-bit static random access memory organized as 65,536 words by 8 bits and operates on a low power supply voltage from 2.7V to 3.6V. Inputs and three-state outputs are TTL compatible and allow for direct interfacing with common system bus structures. Two chip enable inputs are provided for POWER-DOWN and a device enable and an output enable input are included for easy interfacing. Data retention is guaranteed at a power supply voltage as low as 2V.
