MT46V32M4 – 8 MEG x 4 x 4 BANKS
MT46V16M8 – 4 MEG x 8 x 4 BANKS
MT46V8M16 – 2 MEG x 16 x 4 BANKS
Features
VDD = +2.5V ±0.2V, VDDQ = +2.5V ±0.2V
VDD = +2.6V ±0.1V, VDDQ = +2.6V ±0.1V (DDR 400)
Bidirectional data strobe (DQS) transmitted/
received with data, i.e., source-synchronous data
capture (x16 has two – one per byte)
Internal, pipelined double-data-rate (DDR)
architecture; two data accesses per clock cycle
Differential clock inputs (CK and CK#)
Commands entered on each positive CK edge
DQS edge-aligned with data for READs; center-
aligned with data for WRITEs
DLL to align DQ and DQS transitions with CK
Four internal banks for concurrent operation
Data mask (DM) for masking write data (x16 has two
– one per byte)
Programmable burst lengths: 2, 4, or 8
Auto Refresh and Self Refresh Modes
Longer lead TSOP for improved reliability (OCPL)
2.5V I/O (SSTL_2 compatible)
Concurrent auto precharge option is supported
tRAS lockout supported (tRAP = tRCD)
NOTE:
1. Contact Micron for availability of lead-free products.
2. Supports PC3200 modules with 3-3-3 timing.
3. Supports PC2700 modules with 2.5-3-3 timing.
4. -6T is not available in the x16 configuration.

9. CL = CAS (READ) latency.
10. Minimum clock rate @ CL = 2 (-75E, -75Z), CL = 2.5 (-6, -6T, -75),
and CL = 3 (-5B).
11. FBGA package is EOL and no longer available.
