description
The TM8SR64JPU is a 64M-byte, 168-pin dual-in-line memory module (DIMM). The DIMM is composed of eight TMS664814DGE, 8 388 608 x 8-bit SDRAMs, each in a 400-mil, 54-pin plastic thin small-outline package (TSOP) mounted on a substrate with decoupling capacitors. See the TMS664814 data sheet (literature number SMOS690). The TM16SR64JPU is a 128M-byte, 168-pin DIMM. The DIMM is composed of sixteen TMS664814DGE, 8 388 608 x 8-bit SDRAMs, each in a 400-mil, 54-pin plastic TSOP mounted on a substrate with decoupling capacitors. See the TMS664814 data sheet (literature number SMOS690). The TM8SR72JPU is a 64M-byte, 168-pin DIMM. The DIMM is composed of nine TMS664814DGE, 8 388 608 x 8-bit SDRAMs, each in a 400-mil, 54-pin plastic thin small-outline package (TSOP) mounted on a substrate with decoupling capacitors. See the TMS664814 data sheet (literature number SMOS690). The TM16SR72JPU is a 128M-byte, 168-pin DIMM. The DIMM is composed of eighteen TMS664814DGE, 8 388 608 x 8-bit SDRAMs, each in a 400-mil, 54-pin plastic TSOP mounted on a substrate with decoupling capacitors. See the TMS664814 data sheet (literature number SMOS690).

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTE 1: All voltage values are with respect to VSS.

tT Transition time 1 5 ms All references are made to the rising transition of CK unless otherwise noted. NOTES: 11. tAC is referenced from the rising transition of CK that precedes the data-out cycle. For example, the first data out tAC is referenced from the rising transition of CK that is read latency (one cycle after the READ command). Access time is measured at output reference level 1.4 V. 12. tLZ is measured from the rising transition of CK that is read latency (one cycle after the READ command). 13. tHZ (max) defines the time at which the outputs are no longer driven and is not referenced to output voltage levels. 14. For read or write operations with automatic deactivate, tRCD must be set to satisfy minimum tRAS.

serial presence detect
The serial presence detect (SPD) is contained in a 2K-bit serial EEPROM located on the module. The SPD nonvolatile EEPROM contains various data such as module configuration, SDRAM organization, and timing parameters (see tables below). Only the first 128 bytes are programmed by Texas Instruments, while the remaining 128 bytes are available for customer use. Programming is done through an IIC bus using the clock (SCL) and data (SDA) signals. All Texas Instruments modules comply with the current JEDEC SPD Standard. See the Texas Instruments Serial Presence Detect Technical Reference (literature number SMMU001) for further details. Tables in this section list the SPD contents as follows: Table 1 -TM8SR64JPU Table 3 -TM8SR72JPU Table 2 -TM16SR64JPU Table 4 -TM16SR72JPU
