Publication Date: Feb. 2008 Revision: 2.4 2/47 SDRAM 512K x 32 Bit x 4 Banks Synchronous DRAM FEATURES JEDEC standard 3.3V power supply LVTTL compatible with multiplexed address Four banks operation MRS cycle with address key programs - CAS Latency ( 2 & 3 ) - Burst Length ( 1, 2, 4, 8 & full page ) - Burst Type ( Sequential & Interleave ) All inputs are sampled at the positive going edge of the system clock DQM for masking Auto & self refresh 15.6μs refresh interval ORDERING INFORMATION Product No. MAX FREQ. PACKAGE COMMENTS M12L64322A-5TG 200MHz TSOPII Pb-free M12L64322A-6TG 166MHz TSOPII Pb-free M12L64322A-7TG 143MHz TSOPII Pb-free M12L64322A-5BG 200MHz 90BGA Pb-free M12L64322A-6BG 166MHz 90BGA Pb-free M12L64322A-7BG 143MHz 90BGA Pb-free GENERAL DESCRIPTION The M12L64322A is 67,108,864 bits synchronous high data rate Dynamic RAM organized as 4 x 524,288 words by 32 bits. Synchronous design allows precise cycle control with the use of system clock I/O transactions are possible on every clock cycle. Range of operating frequencies, programmable burst length and programmable latencies allow the same device to be useful for a variety of high bandwidth, high performance memory system applications.
