LRS1381

The LRS1381 is a kind of stacked chip with32M flash and 4M SRAM.It is a combination memory organized as 2,097,152 x16 bit flash memory and 262,144 x16 bit static RAM in one package.

The following is about its features.(1)It is not designed or rated as radiation hardened;(2)72pin CSP (LCSP072-P-0811) plastic package;(3)flash memory has P-type bulk silicon,and SRAM has P-type bulk silicon.

What comes next is absolute maximum ratings.(1):power supply is from 2.7 to 3.3 V;(2):supply voltage(VCC) is from -0.2 to 3.9 V;(3):input voltage(VIN) is from -0.2 to VCC+0.3 V;(4):operating temperature(TA) is from -25 to 85;(5):storage temperature(TSTG)is from -55 to 125;(6):F-VPP voltage is from -0.2 to 12.6 V.(7):the access time of the flash memory is 85 ns and 70 ns for SRAM;(8)power supply current for SRAM is 50 mA and the operating current is 8 mA,then standby current is 25 A and the data retention current is 25 A.
