Device:

MCRF250 = 125 kHz Anticollision MicroID tag, 96/128-bit

Temperature Range:

I

=

-40

°C to +85°C

Package:

WF

= Sawed wafer on frame (7 mil backgrind)

W

= Wafer (11 mil backgrind)

S

= Dice in waffle pack

P

= Plastic PDIP (300 mil Body) 8-lead

SN

= Plastic SOIC (150 mil Body) 8-lead

Configuration:

Three-digit hex value to be programmed into the configura-

tion register. Three hex characters correspond to 12 binary

bits. These bits are programmed into the configuration

register MSB first (CB12, CB11...CB1). Refer to example.

SQTP Code:

An assigned, customer 3-digit code used for tracking and

controlling production and customer data files for factory

programming. In this case the configuration code is not

shown in the part number, but is captured in the SQTP

documention.

Examples:

a)

MCRF250-I/W40A =

125 kHz,

industrial

temperature, wafer package, contactlessly

programmable, 96 bit, FSK Fc/8 Fc/10,

direct encoded, Fc/50 data return rate tag.

b)

MCRF250-I/WFQ23 = 125 kHz, industrial

temperature, wafer sawn and mounted on

frame, factory programmed.

The configuration register is:

CB12 CB11 CB10 CB9 CB8 CB7 CB6 CB5 CB4 CB3 CB2 CB1
