To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all devices. Each device has one of three prefixes: X, P, or null (no prefix) (for example, xRM46L852). These prefixes represent evolutionary stages of product development from engineering prototypes through fully qualified production devices/tools.
Device development evolutionary flow:
x and P devices are shipped against the following disclaimer:
"Developmental product is intended for internal evaluation purposes."
Production devices have been characterized fully, and the quality and reliability of the device have been demonstrated fully. TI's standard warranty applies.
Predictions show that prototype devices have a greater failure rate than the standard production devices. Texas Instruments recommends that these devices not be used in any production system because their expected end-use failure rate still is undefined. Only qualified production devices are to be used.
Figure 8-1 shows the numbering and symbol nomenclature for the RM46L852 device.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

The device identification code register identifies several aspects of the device including the silicon version. The details of the device identification code register are shown in Table 8-1. The device identification code register value for this device is:
|TECH||I/O VOLTAGE||PERIPH PARITY||FLASH ECC||RAM ECC||VERSION||1||0||1|
|LEGEND: R/W = Read/Write; R = Read only; -n = value after reset|
|31||CP15||Indicates the presence of coprocessor 15|
|30-17||UNIQUE ID||100011|| Unique device identification number
This bitfield holds a unique number for a dedicated device configuration (die).
|16-13||TECH||Process technology on which the device is manufactured.|
