IS46LR16320C fiche technique
IS43/46LR16320C
8M x 16Bits x 4Banks Mobile DDR SDRAM
Description
The IS43/46LR16320C is 536,870,912 bits CMOS Mobile Double Data Rate Synchronous DRAM organized as 4 banks of 8,388,608 words x
16 bits. This product uses a double-data-rate architecture to achieve high-speed operation. The Data Input/ Output signals are transmitted
on a 16-bit bus. The double data rate architecture is essentially a 2N prefetch architecture with an interface designed to transfer two data
words per clock cycle at the I/O pins. This product offers fully synchronous operations referenced to both rising and falling edges of the clock.
The data paths are internally pipelined and 2n-bits prefetched to achieve very high bandwidth. All input and output voltage levels are
compatible with LVCMOS.
Features
• JEDEC standard 1.8V power supply
• VDD = 1.8V, VDDQ = 1.8V
• Four internal banks for concurrent operation
• MRS cycle with address key programs
- CAS latency 2, 3 (clock)
- Burst length (2, 4, 8, 16)
- Burst type (sequential & interleave)
• Fully differential clock inputs (CK, /CK)
• All inputs except data & DM are sampled at the rising
edge of the system clock
• Data I/O transaction on both edges of data strobe
• Bidirectional data strobe per byte of data (DQS)
• DM for write masking only
• Edge aligned data & data strobe output
• Center aligned data & data strobe input
• 64ms refresh period (8K cycle)
• Auto & self refresh
• Concurrent Auto Precharge
• Maximum clock frequency up to 200MHZ
• Maximum data rate up to 400Mbps/pin
• Power Saving support

- Auto TCSR (Temperature Compensated Self Refresh)
- Deep Power Down Mode
- Programmable Driver Strength Control by Full Strength
or 3/4, 1/2, 1/4, or 1/8 of Full Strength
• Status Register Read (SRR)
• LVCMOS compatible inputs/outputs
• 60-Ball FBGA package
