description
The TM4EP64xxN is a 32M-byte, 168-pin, dual-in-line memory module (DIMM). The DIMM is composed of
sixteen TMS42x409A, 4 194 304 × 4-bit EDO dynamic random-access memories (DRAMs), each in a 300-mil,
26-pin plastic thin small-outline package (TSOP) (DGA suffix) mounted on a substrate with decoupling
capacitors. See the TMS42x409A data sheet (literature number SMKS893). The TM4EP64xJN is available with
an SOJ package (DJ suffix).
The TM4EP72xxN is a 32M-byte, 168-pin DIMM. The DIMM is composed of eighteen TMS42x409A,
4 194 304 × 4-bit EDO DRAMs, each in a 300-mil, 26-pin plastic TSOP (DGA suffix) mounted on a substrate with
decoupling capacitors. See the TMS42x409A data sheet (literature number SMKS893). The TM4EP72xJN is
available with an SOJ packaage (DJ suffix).
operation
The TM4EP64xxN operates as 16 TMS42x409As that are connected as shown in the TM4EP64xxN functional
block diagram. The TM4EP72xxN operates as 18 TMS42x409As that are connected as shown in the
TM4EP72xxN functional block diagram.

serial presence detect
The serial presence detect (SPD) is contained in a 256-byte Serial EEPROM located on the module. The SPD
nonvolatile EEPROM contains various data such as module configuration, DRAM organization, and timing
parameters (see Table 1 through Table 4). 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.
SPD contents for the TM4EPxxxxN devices are listed in the following tables:
Table 1–TM4EP64BxN
