Product Summary

The MTOBB12 is a double data rate DDR SDRAM. The MTOBB12 is a high-speed CMOS, dynamic random-access memory that operates at a frequency of 167 MHz (tCK=6ns) with a peak data transfer rate of 333Mb/s/p. DDR333 continues to use the JEDEC standard SSTL_2 interface and the 2n-prefetch architecture.

Parametrics

MTOBB12 absolute maximum ratings: (1)Supply Voltage: 3.0V to 3.6V; (2)Storage Temperature: -55°C to 125°C; (3)Supply voltage: 3.0V to 3.6V; (4) Operating Temperature: 0°C to 70°C.

Features

MTOBB12 features: (1)167 MHz Clock, 333 Mb/s/p data rate; (2)VDD = +2.5V ±0.2V, VDDQ = +2.5V ±0.2V; (3)Bidirectional data strobe (DQS)transmitted/ received with data, i.e., source-synchronous data capture (x16 has two - one per byte); (4)Internal, pipelined double-data-rate (DDR)architecture; two data accesses per clock cycle; (5)Differential clock inputs (CK and CK#); (6)Commands entered on each positive CK edge; (7)DQS edge-aligned with data for READs; centeraligned with data for WRITEs; (8)DLL to align DQ and DQS transitions with CK; (9)Four internal banks for concurrent operation; (10)Data mask (DM)for masking write data (x16 has two - one per byte).
