Summary description

7/23

LPSDRAM Component

The NAND256-M and NAND512-M devices contain either:

●

one M65KA256AL: 256Mbit (x16) Single Data Rate (SDR) LPSDRAM

●

●

one M65KG256AF: 256Mbit (x16) Double Data Rate (DDR) LPSDRAM

●

one M65KG512AB: 512Mbit (x16) Double Data Rate (DDR) LPSDRAM

●

one M65KC512AB: 512Mbit (x32) Single Data Rate (SDR) LPSDRAM

Refer to Table 1: Product List, for a description of the memories contained in the NAND256-

M, NAND256-M and NAND01G-M devices.

For detailed information on how to use the SDR LPSDRAM devices, refer to the

M65KA256AL and M65KC512AB datasheets which are available from your local

STMicroelectronics distributor.

For detailed information on how to use the DDR LPSDRAM device, refer to the

M65KG256AB datasheet which is available from your local STMicroelectronics distributor.
