General Description The A43L2632 is 67,108,864 bits Low Power synchronous high data rate Dynamic RAM organized as 4 X 1,048,576 words by 32 bits, fabricated with AMIC’s high performance CMOS technology. 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 latencies allows the same device to be useful for a variety of high bandwidth, high performance memory system applications. Features ■ JEDEC standard 3.3V power supply ■ LVTTL compatible with multiplexed address ■ Four banks / Pulse RAS ■ 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 ■ Deep Power Down Mode ■ Burst Read Single-bit Write operation ■ DQM for masking ■ Auto & self refresh ■ 64ms refresh period (4K cycle) ■ Self refresh with programmable refresh period through EMRS cycle ■ Programmable Power Reduction Feature by partial array activation during Self-refresh through EMRS cycle ■ 86 Pin TSOP (II) ■ operating temperature range: 0ºC to + 70ºC ■ Clock Frequency (max) : 166MHz @ CL=3 (-6) 143MHz @ CL=3 (-7)
